A Chimney Liner May Be the Answer

Chimney liners is often the most practical and affordable way to repair a damaged chimney. Chimneys can damage from a number of things such as settling, hurricanes and lightning. However, the most common form of chimney damage is a chimney fire.

In addition to chimney damage, older liners may deteriorate. Additionally, there may not be a liner in there at all!

Reasons to Reline:

  1. Repair damage to the chimney, which could occur by a chimney fire, lightning strike, or settling, etc.
  2. Upgrade old chimneys without chimney liners.
  3. Replace worn, deteriorated liners. This may be allowing smoke, creosote or condensation to seep through the chimney walls.
  4. Properly size the chimney for a new appliance.
  5. Prevent excessive creosote buildup (and risk of a chimney fire) when venting a woodstove through an existing fireplace.
