There’s nothing quite like a cozy fire on a cool New Hampshire day. But before you light the first fire of the season, it’s worth taking a closer look at your chimney to ensure it’s working as it should. Over time, soot, creosote, and other debris can collect inside your chimney, reducing venting performance and increasing the risk of a chimney fire. The tricky part is that much of this buildup happens where you can’t see it. So, how do you know when it’s time to have your chimney cleaned? Here Are Eight Signs to Watch For: 1. There’s Soot or Creosote Buildup in Your Fireplace or Flue. One of the clearest signs that your chimney needs cleaning is soot or creosote buildup inside your fireplace or flue. When wood burns, it produces smoke and combustion byproducts. As those materials travel up the chimney, some can condense along the flue walls and form creosote, a combustible residue that can range from flaky and powdery to hard, shiny, and glazed. If you notice a significant layer of dark soot or creosote inside your fireplace or chimney, it’s time to have a chimney professional evaluate your system. 2. Your Fireplace Has a Strong Smoky or Musty Odor. Does your fireplace give off a smell even when you’re not using it? A strong smoky, burnt, or musty smell coming from your chimney can indicate that creosote deposits have accumulated inside the flue. Note: While an odor doesn’t automatically mean your chimney needs cleaning (moisture intrusion and other chimney problems can also cause odors), it’s a good reason to schedule an inspection. >READ MORE: What’s that smell? Fireplace odor causes and solutions 3. Smoke Is Coming Back Into Your Home. A properly functioning chimney should create enough draft to move smoke and combustion gases up the flue and safely out of your home. If smoke begins spilling back into your living space, something may be interfering with that airflow. Possible Causes Include: Heavy soot or creosote buildup Leaves, twigs, or other debris Bird or animal nests Damper problems Chimney design or draft issues Other obstructions within the flue NOTE: If smoke is entering your home, it’s important to determine the cause. A professional chimney inspection will tell you whether a cleaning will address your chimney’s performance issues or additional services are required. 4. You’re Finding Black Flakes or Debris in Your Fireplace. If you notice black, crusty flakes collecting in your firebox, schedule a chimney inspection before continuing to use it. Why? "These flakes may come from creosote that has loosened inside your chimney and fallen downward," says Admiralty Chimney Owner John Butler, a CCP-certified Master Chimney Technician. John notes that creosote deposits can take several forms, and some are harder to remove than others. Heavy or glazed deposits may require more intensive professional cleaning beyond routine sweeping. 5. Your Fire Isn’t Drafting Like It Used To. Changes in how your fireplace burns can signal that something is going on inside your chimney. Reduced Airflow If you’re suddenly having trouble starting a fire, the fire seems sluggish, or smoke lingers in your home longer than usual, reduced airflow may be part of the problem. "Chimneys depend on unobstructed airflow to create proper draft. Buildup or blockages can interfere with that process," John points out. However, draft problems can have several different causes. Schedule a professional chimney inspection to determine what’s actually going on. 6. You Hear or See Signs of Birds or Animals in Your Chimney. Chimneys can offer attractive shelter for birds and small animals, especially if a chimney cap is damaged or missing. Bird nests, leaves, twigs, and other nesting materials can partially or completely block a flue. Even if you haven’t used your fireplace recently, an obstruction may have developed since the last time the chimney was checked. Listen for scratching, chirping, or movement inside your chimney, and watch for debris appearing in your firebox. >READ MORE: Keeping Critters Out of Your Chimney REMINDER: Lighting a fire in an effort to remove a suspected nest or blockage can cause a chimney fire or smoke buildup in your home. Schedule a chimney inspection instead. 7. You Can’t Remember the Last Time Your Chimney Was Inspected. Sometimes the biggest warning sign is simply not knowing when your chimney was last inspected. The Chimney Safety Institute of America (CSIA) recommends having an annual chimney inspection and notes that masonry fireplaces should generally be swept when there is about 1/8 inch of sooty buildup--or sooner if glazed creosote is present. Even if you only use your fireplace occasionally, it should still be inspected annually. Why? Because animals, moisture, deterioration, and debris can affect a chimney even when few fires have been burned, and a chimney inspection will tell you if it needs a professional cleaning and/or repairs. 8. You’ve Recently Purchased Your Home If you’ve recently moved into a home with a fireplace or wood stove, it’s a good idea to have your chimney evaluated before assuming it’s ready to use. Unless the previous homeowner provides reliable documentation, you may not know: How frequently the fireplace was used When the chimney was last cleaned If there has been a previous chimney fire If repairs are needed What condition the flue liner is in John notes that a professional chimney inspection gives you a clearer picture of the system’s condition and whether cleaning or repairs are recommended before you begin using it. How Often Should a Chimney Be Cleaned? No single cleaning schedule applies to every chimney. How quickly deposits accumulate depends on the kind of fireplace or stove you have, how often it’s used, the type of wood being burned, the chimney system, and burning habits. That’s why The Chimney Safety Institute of America (CSIA) recommends having an annual chimney inspection instead of relying on a fixed cleaning schedule. A professional can determine how much buildup is present and whether the chimney needs sweeping. >READ MORE: Everything You Should Know About Chimney Inspections Why Is Chimney Cleaning Important? Chimney cleaning isn't just about tidiness. "Removing soot, creosote, and obstructions helps your chimney vent properly and can reduce the risk of a chimney fire," John says, noting that a professional inspection and cleaning can also uncover problems that aren't obvious from the fireplace opening. Creosote is particularly important to address because it is combustible. That's why chimneys should be inspected annually and cleaned and repaired as needed to help prevent chimney fires. Get Your Chimney Ready for the Burning Season Once temperatures drop in New England, most fireplaces and wood stoves see heavy use. Getting your chimney checked before you use it will help ensure your system works safely and efficiently throughout the burning season. If you notice soot or creosote, unusual odors, falling debris, smoke entering your home, poor draft, OR if you can't remember the last time your chimney was inspected, contact Admiralty Chimney to schedule a professional chimney inspection.

When most homeowners think about chimney damage, a raging roof fire comes to mind. In reality, the greatest long-term threat to your chimney isn't fire; it's water. Throughout the year, your chimney is exposed to water in many forms--from heavy spring rain to summer humidity to the repeating freeze-thaw cycles of winter. Over time, this moisture penetrates your chimney’s brick and mortar, causing masonry to crack, flake, weaken, and eventually fail. The bad news: Left untreated, this damage can lead to costly repairs. The good news: Waterproofing your chimney is a cost-effective way to prevent damage. Why Water is so Damaging to Chimneys Brick and mortar naturally absorb moisture. During colder months, that trapped water freezes and expands, creating pressure inside the masonry. As this process repeats year after year, it causes: Cracked bricks Deteriorating mortar joints Spalling (flaking or chipping masonry) Chimney crown damage Interior water leaks Mold and mildew growth Premature chimney deterioration Because water damage develops over time, many homeowners don’t realize they have a masonry problem until significant and costly repairs are required. This is why scheduling a professional annual chimney inspection is so important. Five Benefits of Professional Chimney Waterproofing 1. It Prevents Costly Water Damage. A professional waterproofing treatment creates a breathable barrier that repels rain and snow before moisture can penetrate your chimney's masonry. Preventing water intrusion today can save thousands of dollars in future masonry repairs. 2. It Prevents Mold and Mildew Growth. When water enters a damaged chimney, it can migrate into your home’s walls, ceilings, and framing. This excess moisture creates ideal conditions for mold and mildew growth, potentially affecting both your home and your indoor air quality. 3. It Extends the Life of Your Chimney. Your chimney is built to last for decades-- but only if it's properly maintained. Waterproofing protects masonry from the constant cycle of moisture absorption and freeze-thaw damage, helping preserve the structural integrity of your chimney for years to come. 4. It Improves Energy Efficiency. Damaged masonry allows heat to escape more easily while permitting unwanted moisture into your home. Keeping your chimney dry helps maintain its performance and contributes to a more energy-efficient home, particularly during the heating season. 5. It Preserves Your Home's Appearance. A chimney is one of the most visible architectural features of your home. Cracked mortar, stained brick, and deteriorating masonry can negatively impact curb appeal. Waterproofing helps keep your chimney looking clean, well-maintained, and structurally sound. Before Waterproofing Your Chimney… Applying a waterproof coating over damaged masonry doesn't solve the underlying problem; it simply hides it. Before waterproofing your chimney, schedule a professional chimney inspection to identify and address any masonry damage, deteriorated mortar joints, cracked crowns, or other issues. Can You Waterproof Your Chimney Yourself? You could, but we don’t recommend it. Professional chimney waterproofing uses a specially formulated, vapor-permeable sealant that repels liquid water while allowing the masonry to release water vapor naturally. This is important because chimney masonry needs to "breathe." Products that trap moisture inside the brick can actually accelerate deterioration. A professional waterproofing application also ensures your entire chimney is treated safely and evenly without exposing you to the hazards of working on a roof. Is Chimney Waterproofing Worth The Investment? Compared with rebuilding damaged masonry, replacing bricks, repairing crowns, or correcting water intrusion inside your home, chimney waterproofing is a relatively small investment that can significantly reduce future repair costs. In New England, where chimneys are exposed to harsh winters and frequent freeze-thaw cycles, waterproofing is one of the most effective preventative maintenance services available.

Your chimney masonry may be strong, but it certainly isn't indestructible. Over time, nature’s elements, including heavy rain, snow, ice, and humidity, make it expand, contract, and absorb moisture. This leads to cracks, loose bricks, deteriorating mortar joints, and even structural instability. The good news? Most masonry problems can be repaired before they become major (and expensive) issues. Here's what every homeowner should know about chimney masonry repair: What Does Chimney Masonry Repair Involve? Chimney masonry repair involves restoring the brick, stone, mortar, or concrete components of your chimney to keep it safe, structurally sound, and protected from water damage. Depending on the condition of your chimney, repairs may include: Replacing damaged or loose bricks Tuckpointing deteriorated mortar joints Repairing cracked crowns Rebuilding damaged chimney sections Replacing flashing around the chimney Waterproofing the masonry to help prevent future damage Signs Your Chimney Needs Masonry Repair: Cracked or Missing Mortar Mortar joints naturally wear down over time. If you notice gaps, crumbling mortar, or missing sections between bricks, water can begin working its way into the chimney structure. Loose, Cracked, or Spalling Bricks Bricks that are cracking, flaking, or breaking apart (known as spalling) are usually a sign that moisture has entered the masonry and repeatedly frozen and thawed. White Staining (Efflorescence) White, chalky deposits on the outside of your chimney suggest that moisture has penetrated its masonry. The staining itself isn't harmful, but it usually suggests there is a water problem that needs to be addressed. Water Leaks Around the Fireplace Water stains on ceilings or walls near the chimney, damp fireplace walls, or musty odors often point to masonry or flashing problems. Pieces of Brick or Mortar on the Ground If you find fragments of brick or mortar around the base of your chimney, deterioration is already occurring and should be repaired promptly. Leaning or Tilting If your chimney is leaning or separating from your home, it is a serious structural concern that requires immediate professional attention. More Than a Cosmetic Issue A small crack in the masonry of a chimney is much more than a cosmetic issue. Even tiny openings allow water to penetrate your chimney’s masonry. Once moisture gets inside, every freeze-thaw cycle causes it to expand, making cracks larger and weakening your chimney over time. Delaying masonry repairs can lead to: Extensive brick deterioration Interior water damage Damaged chimney liners Structural instability Costly chimney rebuilds Safety hazards for your home and family Addressing minor masonry issues early is almost always far less expensive than waiting until major chimney reconstruction is required. When Is the Best Time for Chimney Masonry Repair? The ideal time to schedule chimney masonry work is during the spring, summer, or early fall. These seasons typically provide: Warmer temperatures needed to allow mortar to cure properly Lower humidity for better masonry performance More predictable weather conditions Plenty of time to complete repairs before heating season begins Scheduling repairs before fall also ensures your fireplace and chimney are ready for safe use when colder weather returns. What if you find damage during the winter? If masonry damage is discovered during the winter, temporary solutions may sometimes be used until permanent repairs can be completed under better weather conditions. The Chimney Masonry Repair Process Every chimney is different, but most repair projects follow a similar process. 1. Thoroughly Inspecting Your Chimney We thoroughly inspect your chimney to identify masonry issues so we can address the underlying cause of the damage rather than simply repairing the symptoms. 2. Removing Damaged Materials We carefully remove loose bricks, deteriorated mortar, cracked concrete, and any other damaged components—without disturbing the surrounding structure. 3. Repairing and Restoring Whenever possible, we color-match new mortar, replace damaged bricks, and repair and restore damaged bricks, crowns, flashing, and other components as needed. The goal is to blend repairs seamlessly with the existing chimney while restoring structural integrity. 4. Waterproofing (When Appropriate) After repairs are complete, a professional-grade breathable waterproofing treatment may be applied to your chimney. This helps repel rainwater while still allowing trapped moisture inside the masonry to escape naturally. 5. Final Inspection Before the project is complete, we inspect your chimney again to ensure repairs meet safety standards and it is ready for years of safe and reliable service. Addressing Small Masonry Problems Before They Become Big Ones It’s unlikely that any chimney masonry damage will improve on its own. Small cracks eventually become larger ones, minor water leaks turn into larger, costlier problems, and deteriorating mortar can compromise the stability of your entire chimney. At Admiralty Chimney, our CSIA-certified chimney professionals provide detailed inspections, expert masonry repairs, and honest recommendations to help homeowners protect both their chimneys and their homes. Whether your chimney needs minor tuckpointing or more extensive masonry restoration, we'll help restore it safely and correctly the first time. If you've noticed signs of chimney deterioration, or it's been a while since your last inspection, now is the time to schedule a professional evaluation so any needed repairs can be addressed before the burning season. Call us at (603) 594-0400 or visit us online to schedule an appointment.

There’s nothing better than the smell of a wood-burning fire on a cold New England evening. But once winter ends and summer humidity arrives, you may notice something very different coming from your fireplace: a strong, unpleasant odor. If your fireplace smells sour, musty, smoky, or even like something rotting, you’re not alone. Over the summer, we often hear from homeowners who are surprised when their chimney suddenly starts to smell, even though it hasn't been used. Here’s why it happens, and what you can do about it. The Triple Threat: Moisture, Humidity & Creosote Buildup In most cases, summer chimney odors are caused by a combination of moisture, humidity, and creosote buildup inside the flue. We all know what moisture and humidity are, but what is creosote? It is the dark, tar-like residue left behind after burning wood. Over time, it coats the inside of your chimney and absorbs into porous masonry surfaces. During hot, humid weather, warm outside air moves down the chimney and mixes with moisture and acidic creosote deposits inside the flue. The result is a musky, smoky, or sour odor that can spread throughout your home. The odor is often more noticeable: On humid or rainy days When the air conditioning is running At homes with tightly sealed windows and doors In lower-pressure areas, such as basements >Did you know? When your air conditioning system is running, it can pull air down the chimney, bringing those odors directly into your living space. Other Common Causes of Chimney Odors Creosote is one of the most common culprits, but it’s not the only one. Summer chimney smells can also be caused by: Animal Nests or Critters Birds, squirrels, raccoons, and other animals often seek shelter inside uncapped chimneys during the spring and summer months. Nesting materials, droppings, or trapped animals can create extremely unpleasant odors. Water Intrusion Rainwater entering through a damaged crown or flashing, or a missing chimney cap, can soak into the chimney masonry, causing interior deterioration and musty odors. Debris Buildup Any leaves, twigs, soot, or other debris trapped inside the flue can retain moisture and contribute to odors. Mold or Mildew Excess moisture inside a chimney can sometimes lead to mold growth, especially in damp or poorly ventilated systems. How to Reduce Summer Fireplace Odors Schedule a Professional Chimney Cleaning & Inspection. Because chimney odors can have multiple causes, the best first step is to schedule a professional chimney inspection. Our certified chimney technicians can quickly identify the source of the smell and recommend the proper solution before the problem worsens. Install a Chimney Cap. A properly installed chimney cap helps protect your chimney system by Keeping rainwater out Preventing animals and nesting debris from entering Reducing downdrafts Minimizing moisture-related odors If your chimney does not currently have a cap, or if the existing cap is damaged, summer is the ideal time to install or replace one. Repair Damaged Masonry. Unfortunately, chimney masonry naturally absorbs water over time, which can lead to odors and structural damage, including cracked mortar joints, damaged bricks, and deteriorating crowns. Professional masonry repairs help seal vulnerable areas in your chimney and prevent water intrusion. Waterproof Your Chimney. Professional chimney waterproofing is one of the most effective ways to protect masonry from long-term moisture damage. It creates a breathable barrier that helps repel water while still allowing trapped moisture vapor to escape. When properly applied, chimney waterproofing can help protect your chimney for years. Remove Fireplace Ashes. Leaving ashes in the firebox throughout the off-season can contribute to lingering odors. At the end of the burning season, be sure to remove any remaining fireplace ashes, using a non-combustible container. Close the Damper When Your Fireplace Isn’t in Use. Closing the damper and glass fireplace doors when your system is not in use can help reduce the amount of humid outside air entering your home through the chimney. (Just remember to reopen the damper before starting your next fire.) Why Summer is the Best Time for Chimney Service Most homeowners wait until fall to schedule chimney cleanings and inspections. However, summer is actually one of the best times to service your chimney because: You will beat the “fall rush.” You can eliminate odors before they worsen. You can address any problems before the burning season. Your fireplace will be ready for when you need it most. Chimney Cleaning, Inspection & Repair in NH and MA Whether you’re dealing with unpleasant fireplace odors, water leaks, masonry damage, or overdue maintenance, the certified professionals at Admiralty Chimney can help. Summer is the perfect time to schedule your annual chimney cleaning and safety inspection so your system is clean, safe, and ready for fall.

If your chimney doesn’t have a cap, you might be wondering if it’s really necessary. The short answer is yes. A chimney cap is a simple and effective way to protect your chimney and home. In New Hampshire, where we deal with heavy rain, snow, and freezing temperatures, that protection matters even more. What is it and what does it do? A chimney cap is a protective stainless steel covering installed at the top of your chimney. Typically, it includes a mesh screen and a solid top that allows smoke to escape while keeping unwanted elements (water, debris, critters) out. Chimney Cap Benefits: 1. Preventing Water Damage You may not know this, but water is one of the biggest threats to your chimney. If you don’t have a chimney cap, rain and snow can easily get inside it. Over time, this leads to moisture damage within the flue and masonry, and eventually to deterioration and costly repairs. A chimney cap acts like a roof for your chimney, helping keep it dry year-round. 2. Keeping Critters Out of Your Chimney Birds, squirrels, raccoons, and other small animals often see a chimney as a safe place to nest, especially during cold weather. Without a cap, it’s only a matter of time before an uninvited guest moves in yours. Once inside, these critters can cause serious problems, including fire hazards and carbon monoxide buildup. 3. Blocking Debris Small branches, twigs, leaves, and other debris can easily get into an open chimney, creating a fire hazard. By restricting airflow, debris buildup can also allow dangerous carbon monoxide gas to back up into your home. A chimney cap helps prevent debris buildup, reducing the risk of fire and improving ventilation. 4. Reducing Downdrafts Brrr. Strong winds can push cold air down your chimney, creating drafts and decreasing energy efficiency. Installing a chimney cap helps reduce downdrafts, improving the performance of your fireplace or heating system. 5. Decreasing the Risk of a Roof Fire The mesh screen on a chimney cap can also act as a spark guard, preventing hot embers from escaping onto your roof. This added layer of protection can help reduce the risk of accidental roof or exterior fires. What Happens If You Don’t Have a Chimney Cap? It might not seem like a big deal at first, but not having a chimney cap can lead to serious (and expensive) problems over time, including water damage to your chimney liner, masonry, and even your home’s interior. And in New Hampshire’s climate, freeze-thaw cycles can exacerbate moisture damage, accelerating cracking and structural issues. Small Investment. Big Benefits. Compared to the cost of removing animal nests or repairing water damage, a chimney cap is a small investment that can extend your chimney’s lifespan and improve your home's overall comfort and safety. Chimney Cap Installation in Southern NH & Northern MA For over 20 years, Admiralty Chimney has been a trusted installer of chimney caps in southern New Hampshire and northern Massachusetts.

When most homeowners think about chimney damage, fire comes to mind. While a fire can cause devastating damage, there’s another culprit that quietly deteriorates chimneys before homeowners realize there is a problem: water. At Admiralty Chimney, we’ve seen how quickly moisture can compromise a chimney’s structural integrity. For this reason, it’s important to know the common signs of water damage and how to prevent it. But first, let’s discuss WHY chimneys are so susceptible to water damage. Chimneys are built with porous materials--like brick, mortar, and concrete--that absorb water. During the winter months, absorbed water goes through repeated freeze-thaw cycles. Over time, it causes bricks to crack, mortar to crumble, and chimney liners to deteriorate . Signs Your Chimney Has Water Damage Water damage doesn’t always show up immediately, so be on the lookout for these common signs: Cracked or missing mortar joints Spalling bricks (flaking or popping surfaces) White staining (efflorescence) on the chimney exterior Rust on the damper or firebox Water stains on ceilings and walls Musty odors coming from the fireplace Leaning or tilting chimney structure If you notice any of these signs, contact our chimney experts so we can take action before the problem worsens. How Water Gets Into Your Chimney Several factors allow water to enter your chimney system: Lack of a waterproofing sealant causes bricks to absorb water like a sponge. Condensation buildup occurs when a system is improperly vented. A damaged or missing chimney cap leaves the flue open to rain and snow. A Cracked crown or chimney top allows water to seep inside the chimney. Deteriorated mortar joints create pathways for moisture. Improperly sealed or installed flashing allows water to seep in. Often, it’s not just one issue--but a combination of issues--that leads to significant chimney damage. Long-Term Effects of Ignoring Water Damage Water damage gets worse over time, leading to: Structural instability of the chimney Interior home damage, including ceilings and walls Mold and mildew growth Reduced heating efficiency Expensive rebuilds or full chimney replacement Unfortunately, what starts as a small chimney crack can quickly become a major repair project. How to Protect Your Chimney From Water Damage Although water can cause devastating damage to your chimney, you can take measures to prevent it by: 1. Installing a chimney cap A chimney cap helps keep rain, snow, debris, and small critters out of your flue. 2. Applying a waterproof sealant Professional-grade waterproofing allows masonry to “breathe” while repelling water. 3. Repairing or replacing the chimney crown The crown is your chimney’s first line of defense. Keeping it sealed and crack-free is essential. 4. Maintaining the chimney flashing Ensure the metal flashing around your chimney base is tight and properly sealed to prevent roof leaks. 5. Scheduling an annual inspection Routine chimney inspections catch small issues before they become expensive problems. What to do if You Already Have Water Damage on Your Chimney: If your chimney is already showing signs of water damage, contact us as soon as possible to schedule any needed repairs. Repair solutions vary according to the type of damage and may include: Tuckpointing (repairing mortar joints) Crown repair or rebuild Chimney cap installation Waterproofing treatment Flashing repair Partial or full rebuild in severe cases Note: Summer is the best time to address chimney masonry repairs in New Hampshire, because the warmer, drier conditions allow the mortar and/or sealant to cure properly. Chimney Water Proofing & Water Damage Repair in Southern NH & Northern MA Water may be the most common cause of chimney damage, but it’s also the most preventable.

While winter tends to linger in New England, we’re definitely approaching the end of the burning season. Now is the time to think about your chimney and fireplace’s maintenance and long-term care. Why? Because what you do after  the season can have a big impact on your heating system’s safety, efficiency, and repair costs down the road. Here’s what you should be considering as spring approaches. 1. Schedule a chimney inspection. With regular use, soot, creosote, and debris build up inside your chimney. After the burning season, scheduling a professional chimney inspection will help: Identify creosote buildup (a leading cause of chimney fires). Detects cracks or damage in the flue. Spot early signs of water intrusion or structural issues. Spring inspections are ideal because you’ll have more scheduling flexibility and plenty of time to address any issues before next fall. 2. Schedule a chimney cleaning. Even if you didn’t use your fireplace a lot this season, even small amounts of creosote buildup can become dangerous over time. Cleaning your chimney at the end of the season: Removes flammable residue. Prevents lingering smoky odors during humid months. Ensures your system is ready for next year. Again, it’s much easier (and often more convenient) to schedule a chimney cleaning now, rather than scrambling in the fall when everyone else is booking appointments. 3. Check for moisture and water damage. Melting winter snow, spring rain, and increased humidity can wreak havoc on your chimney. Water is one of the most damaging elements for masonry chimneys, leading to cracking, spalling, and deterioration. After the burn season ends, take a moment to look for: White staining (efflorescence) on the exterior brick Rust on the damper or firebox components Musty or damp odors coming from the fireplace If you notice any of these signs, it’s worth having a professional assess the situation. Preventative waterproofing or minor repairs now can help you avoid costly work in the long run. 4. Inspect the chimney cap and crown. Caps and crowns protect chimneys from water damage, animal invasions, and debris buildup. Winter weather can be especially harsh on these components, causing cracks or loosening. A quick inspection can help identify: Missing or damaged chimney caps Cracks in the crown that allow water in Blockages from leaves, animal nests, or debris Addressing these issues in the off-season ensures your chimney stays protected year-round. 5. Close the damper (but keep airflow in mind). Once you’re done using your fireplace for the season, ensure the damper is properly closed to prevent drafts and improve energy efficiency. Proper damper use can help: Reduce energy loss from your home Prevent humid air from entering the chimney system Keep pests from making their way inside Note: Before closing your system for the season, ensure any residual moisture has dried out.  6. Take care of any needed repairs. A common mistake many homeowners make is waiting until the first cold snap to address any needed chimney concerns or repairs. By then, most chimney professionals are booked weeks out, and any minor issues may have become larger, costlier problems. Spring and summer are the best times to: Repair cracked flue liners Replace damaged components Repoint deteriorating mortar joints Getting ahead of repairs ensures your fireplace is safe and ready when you need it most. 7. Think ahead to next season. Take a moment to reflect on how your fireplace performed this winter. Did you notice smoke backing up into the room? Did you experience any unusual odors or have difficulty starting fires?  These are all clues that your system may need attention. Addressing these issues now means you’ll be able to enjoy your fireplace with confidence in the next burning season. Remember: A Little Attention Goes a Long Way Your chimney and fireplace work hard all winter long. Giving them a little attention as the season winds down will extend your system's lifespan and keep your home and family safe. Contact  our expert team today to schedule your inspection and cleaning.

A fireplace is a beloved feature in many New England homes, providing warmth and comfort during the long winter months. But like any complex system, over time, problems can develop that affect its safety and efficiency. At Admiralty Chimney, we help homeowners identify and resolve fireplace and chimney issues before they become safety hazards or lead to costly repairs. Below are some of the most common problems we see--and what you can do about them. 1. Smoke Coming Into the House What’s going on? If smoke enters your home instead of going up the chimney, it’s usually a drafting problem. Common causes: Creosote buildup (narrows the flue) Blocked chimney (nests, debris, snow, or ice) Cold air trapped in the flue Improper chimney height or design Troubleshooting tips: Make sure the damper is fully open before lighting a fire Crack a window slightly to improve airflow Warm the flue by lighting a rolled newspaper before starting a fire If smoke problems persist, contact us , and we’ll come take a look at your system. 2. Excessive Creosote Buildup What’s going on? Creosote is a black, tar-like substance that forms when wood doesn’t burn completely. In New England’s extended burning season, creosote can accumulate quickly. Why it matters: It’s highly flammable It reduces chimney efficiency It’s the leading cause of chimney fires Troubleshooting tips: Burn only seasoned, dry firewood Avoid smoldering or low-temperature fires Schedule annual chimney cleanings Creosote   cannot be safely removed without professional tools, so don’t try to scrape it yourself. 3. Chimney Leaks and Water Damage What’s going on? Water is one of the most damaging elements for chimneys, especially with New England’s freeze-thaw cycles. Common entry points: Cracked or missing chimney crown Damaged flashing Porous or deteriorating masonry Missing chimney cap Troubleshooting tips: Look for water stains on ceilings or walls near the chimney Check for rusted dampers or firebox components Install a chimney cap to keep rain and snow out Ignoring water damage can lead to major structural repairs.  Contact our team  to schedule an inspection and determine the best course of action. 4. Cracked or Deteriorating Masonry What’s going on? Your brick-and-mortar chimney expands and contracts with temperature fluctuations. Why it matters: Over time, this can cause cracks, loose bricks, or crumbling mortar joints. Troubleshooting tips: Inspect your chimney exterior each spring and fall Look for white staining (efflorescence), which signals moisture issues Address small cracks early before they worsen Schedule any needed masonry repairs during the spring and summer months, when temperatures are warm enough for the mortar to cure properly . 5. Fireplace Won’t Stay Lit What’s going on? If your fire keeps going out, airflow is usually the culprit. Possible causes: Closed or partially closed damper Blocked flue Negative air pressure in the home Oversized firebox or undersized chimney Troubleshooting tips: Confirm the damper is fully open Use dry kindling and proper fire-building techniques Avoid running kitchen or bathroom exhaust fans while starting a fire Persistent issues should be evaluated by a chimney professional. Contact our office  to schedule an appointment.  6. Strange Odors From the Fireplace What’s going on? Fireplace odors are common in humid New England summers or after heavy rain. Typical causes include: Creosote mixing with moisture Animal nesting materials Poor ventilation Troubleshooting tips: Keep the damper closed when the fireplace isn’t in use Install a chimney cap Schedule a cleaning  if odors linger > Related Reading: What’s that smell? Fireplace odor causes and solutions . When DIY Troubleshooting Isn’t Enough While some chimney problems can be spotted early by homeowners, most are identified by experienced professionals with the proper training and equipment.

When temperatures plummet in New England, there’s nothing like a warm fire to take the chill off. But can your fireplace get too hot ? Yes. This is called over-firing , and it can damage your fireplace or even cause a chimney fire. Here are the causes and signs of over-firing, along with how to prevent it. Causes of over-firing: Too much fuel: You don’t need to fill every square inch of your firebox with wood. Most standard fireplaces accommodate 2 to 3 logs measuring 3 to 6 inches in diameter and 16 to 18 inches in length. Once you have a good fire going, add one log at a time to maintain steady heat.  Too much oxygen:  While oxygen is essential for a strong, efficient fire, too much air  can cause it to burn too quickly, reducing heat output and increasing wear on your fireplace and chimney.  NOTE: Air-pumping bellows should only be used with a stagnant fire. Burning the wrong materials: Use only seasoned hardwood  (oak, maple, ash, or birch) with a 15-20% moisture content, as it burns  more predictably and at a safer temperature. >Related Reading: 8 Things You Should Never Burn in Your Fireplace Signs that your fireplace is too hot: Recognizing the signs of over-firing can help prevent damage and keep your home and family safe: Loud roaring sounds similar to a blowtorch or a freight train Flaking, cracked, or broken firebricks Strong metallic burning odors Glowing red dampers, grates, or doors Warping or deformed metal parts Sparks or embers shooting up the flue Preventing over-firing: Only burn seasoned hardwood.

Before you kick off the holiday season, we encourage you to review these fireplace and chimney safety reminders with your family. A little preparation goes a long way in keeping your home warm and safe this winter. 1. Schedule a chimney cleaning and inspection. If you haven’t done so already, schedule your annual chimney cleaning and inspection so we can check for creosote buildup, cracks, blockages, or other hazards that could make your fireplace unsafe. Starting the season with a clean, well-maintained chimney not only protects your home but also helps your fireplace operate more efficiently. 2. Only burn seasoned firewood. Fresh-cut or damp wood produces heavy smoke and accelerates creosote buildup in the chimney. Stick with well-seasoned hardwoods—such as oak, birch, or maple—for a hotter, cleaner burn that helps keep your chimney healthier throughout the winter. 3. Keep holiday décor at a safe distance. Garlands, stockings, and other festive decorations look great around the hearth, but they should never be too close to the flames. Keep all décor at least three feet away to prevent accidental ignition. 4. Toss—don’t burn— your wrapping paper. Wrapping paper burns too quickly and can send embers up the flue, potentially igniting creosote deposits. Dyed and inked paper can also release harmful fumes. Toss your gift wrap in the trash or recycling bin instead. 5. Never leave a fire unattended. While it may be tempting to walk away from a dwindling fire, never leave your fireplace unattended until the flames and embers are fully extinguished.  Tip:  Spread the coals with your fireplace tools so they cool more quickly. 6. Don’t overfill your firebox. Well-meaning guests may try to add extra logs to “keep the fire going,” but too much fuel can create excessive heat and stress your chimney system . Overloaded fires increase creosote production and can damage brick or mortar. A moderate, controlled fire is safer and just as enjoyable. 7. Dispose of ashes safely. Because fireplace ashes can retain heat well after the flames have disappeared, it’s essential to remove and store them properly. Reminder:  Always place ashes in a metal container with a tight-fitting lid. Be sure to store it away from your home, garage, or any other structure that could catch fire. 8. Test smoke alarms and carbon monoxide detectors. Test your smoke alarms and carbon monoxide detectors to ensure they are working and replace batteries as needed. Keep a fire extinguisher within easy reach and make sure everyone at home knows its location and how to use it. 9. Get a fireplace screen. If you don’t have one already, place a screen in front of your fireplace to contain sparks and keep children and pets a safe distance from the hearth.

Your fireplace is the coveted spot in your home during the cold weather, offering a place of coziness, comfort, and respite on a chilly day. While it can be tempting to toss a few household items in your fireplace to get the fire going, it’s important to remember that this quick fix can have long-term health and safety consequences. Below are eight things you should never burn in your fireplace. 1.Cardboard Cardboard is often treated with chemicals that when burned can release hazardous fumes into the air that are harmful to breathe. It is also possible for burning cardboard to escape through an unscreened hearth, or float up the flue through an uncapped chimney . This is especially dangerous since any burning cardboard that enters the chimney can ignite creosote within the flue . 2.Colored Paper The inks used in newspaper inserts, coupon handouts, glossy magazines and other items contain metals and pigments that release toxic fumes when burned. Like cardboard, bits of burning paper can float up and out an uncapped chimney, putting your roof and nearby structures at risk of fire. 3.Seasonal Decorations and Wrappings The holidays bring with it festive decorations and wrappings that contain chemicals and coloring that can generate hazardous fumes. They are probably very light and can easily go airborne once they catch on fire. 4.Wet Firewood Unseasoned, or wet, firewood can contain up to 45 percent water. Burning high-moisture content wood will smoke and lead to rapid creosote buildup in the chimney liner. Reduce the risk of buildup by burning only dry firewood and having your chimney professionally cleaned and inspected . 5.Christmas Trees and other Evergreen Wood It can be tempting to cut up and burn your live Christmas tree in your fireplace. But your tree, wreath, and other evergreen woods are not safe to burn. In addition to not being properly seasoned, evergreen wood contains high levels of resin that catch fire quickly and produce a hot flame . This wood burns so fast that the fire will fizzle out quickly, and the high resin content leaves heavy creosote deposits in your chimney. 6.Garbage Many people have fallen into the habit of tossing a used plastic-foam cup or paper plate into an open fire. Most consumer products contain chemicals that produce hazardous fumes when burned. Toxic trash items contain plastic, which releases a category of toxins known as dioxins. When inhaled, this level of toxin can lead to major health risks, such as internal organ damage, respiratory symptoms, and headaches. 7.Fresh Fruit Peels Adding scents to your fireplace delivers aromas of oranges, lemons, and apples, however fresh, moist fruit peels will smolder in a fire, and lead to abundant smoke and creosote buildup . A better course of action is to dry your fruit peels at a low temperature in the oven, and then toss them on your fire. You’ll still get the fresh scent you want, but without the moisture. 8.Dryer Lint Dryer lint may be an effective campfire starter, but keep it out of your fireplace. The synthetic fibers in dryer lint can release dangerous chemical fumes into your home and chimney.

Please take a moment to review these chimney and fireplace safety tips and contact us if you have any questions. Top Tips for Chimney and Fireplace Safety 1. Schedule an annual chimney inspection. The National Fire Protection Association (NFPA) and the Chimney Safety Institute of America (CSIA) recommend that all chimneys, fireplaces, and vents be inspected at least once* a year. During your annual inspection, our certified technicians will check for chimney blockages, damage, and creosote buildup  that can cause a fire or carbon monoxide leaks. *This guideline applies even if you don’t use your chimney very often. 2. Keep your chimney clean. If your inspection reveals any buildup, schedule a professional chimney cleaning before using your fireplace for the season. Routine sweeping removes soot and creosote that could easily ignite. 3. Burn the right type of wood. Avoid burning wet or green wood, as it produces excessive smoke and sticky creosote. Use seasoned hardwoods like oak, maple, or birch for cleaner, hotter, and safer fires. > LEARN MORE: How to Select and Store Firewood   4. Know what NOT to burn in your fireplace. In addition to unseasoned hardwood, here is a list of what not to burn in your fireplace: Cardboard Colored Paper Seasonal Decorations and Wrappings Wet Firewood Christmas Trees and Other Evergreen Wood Garbage Fresh Fruit Peels Dryer Lint 5. Install a Chimney Cap A chimney cap  prevents birds, leaves, and other debris from entering your flue, reducing blockages and keeping out rain or snow that can damage your chimney’s interior. 6. Use a Fireplace Screen or Door A sturdy fireplace screen or glass door stops sparks and embers from escaping into your living space, protecting your flooring and furnishings from stray flames. 7. Keep Decorations and Furniture at a Safe Distance It’s important to remember that heat radiating from a fireplace or chimney can ignite nearby materials. Always keep decorations, curtains, and furniture at least three feet away from your hearth or chimney area. This is especially important during the holidays, when garlands, stockings, and other flammable decorations are often placed too close to the fire. 8. Test Smoke and Carbon Monoxide Detectors No matter how well you maintain your chimney, working smoke and CO detectors are essential. Test them monthly and replace batteries twice a year for reliable protection.
