A chimney needs relining when the flue liner is cracked, deteriorated, or missing, or when you change heating appliances. A damaged liner is a fire and carbon monoxide hazard, so relining is a safety repair, not optional.
When relining is needed
A cracked or spalling clay liner, an unlined older chimney, damage after a chimney fire, or installing a new stove or insert that needs a properly sized liner.
Warning signs
Pieces of clay tile in the firebox, draft problems, rapid creosote buildup, or a failed camera inspection. The liner is hard to judge without a camera.
Why it matters
The liner shields your masonry and home from heat and corrosive gases. A failed liner can let heat and carbon monoxide reach framing, which is why relining should not wait.
