What a chimney liner does
A liner is the protective channel inside your chimney that carries smoke and gases out of the home. It keeps intense heat away from the surrounding framing and stops acidic byproducts from eating into the masonry.
Older homes often have clay tile liners that crack with age or after a chimney fire. A stainless steel liner is the most common, long-lasting fix, and it is often required when you install a new insert, stove, or high-efficiency furnace.
You may need a new liner if…
- An inspection found cracked, shifted, or missing flue tiles
- You had a chimney fire, even a small one
- You are installing a wood or gas insert or a new stove
- You are replacing your furnace or water heater
- Tile shards or crumbling mortar are appearing in the firebox
What a quality relining job includes
- A camera inspection to confirm the liner’s condition and size
- Correctly sized stainless steel liner for your appliance
- Insulation where required by the manufacturer and code
- New top plate and rain cap
- Post-install inspection and paperwork
