6 Signs your Chimney Liner Needs to be Replaced

Some consider chimney liners to be the unsung hero of the chimney system. Tucked within the brick masonry, hidden from plain sight, your chimney liner silently improves the safety of your fireplace with no pomp and circumstance. A true behind-the-scenes component of your chimney system, how would know when this vital structure needs to be replaced? Here are six tell-tale signs from the CCP-certified pros at Admiralty Chimney.

What does my chimney liner do?

A chimney liner keeps toxic gas, smoke and creosote from entering your home and prevents the chimney structure from being damaged by heat. These liners are so important that building codes require them in fireplaces. If a liner is missing or damaged, it can lead to serious consequences. There are certain situations that suggest a liner needs replacing, such as:

1. There is an excessive amount of efflorescence on your bricks.

Efflorescence, a white, powdery substance on the surface of your bricks, is a sign that your flue liner is cracked or has lost its seal. This is a serious condition that will cause rapid brick and mortar deterioration.

2. There are broken shards or flakes on your fireplace floor.

Older clay chimney liners will start to crack over time, leaving pieces of clay in your hearth. Without having an expert take care of a cracked liner, it increases the risk of chimney fires.

3. The fire is producing room-filling smoke.

A chimney liner is responsible for moving smoke outside the home. If your home is smoky, it could be a sign that your liner needs to be replaced. This issue can lead to a number of health problems including carbon monoxide poisoning, asthma attacks and other respiratory issues.

4. Your chimney hasn’t been inspected.

If you can’t remember the last time you had professional technicians inspect your chimney, then it has been too long. Arrange for a safety inspection to examine and assess the condition of your chimney and liner.

5. Your chimney liner is old.

Certain types of chimney liners could last around 20 years, while budget liners could only last five years. Additionally, if your family uses the fireplace often, then the frequent wear and tear can cause the flue liner to deteriorate quicker.

6. You’ve purchased a new energy-efficient heating system.

When you replace your heating system for a high-efficiency model, or to a type of heater that you haven’t used before, it is a good idea to get a new liner installed. An older chimney liner may not provide proper ventilation for a new system.

What do I do if I’m unsure about needing a liner replacement?

Scheduling a professional chimney inspection is the best way to let you know when you need a new liner. A CCP-certified chimney technician can alleviate or confirm your concerns by taking a thorough look at the condition of your liner and chimney system. If you suspect that it’s time for a chimney liner replacement, contact Admiralty Chimney for an inspection.
