Modern furnaces don’t waste energy by sending a lot of heat up a chimney. As a result, temperatures in the flue drop low enough to produce condensation. This water combines with acids in the flue to create acidic moisture.
Clay liners are particularly vulnerable to this acidic moisture assault. As a result we often find fire-clay tiles that are in such bad shape that it can be a carbon monoxide risk. In addition to safety issues, this moisture problem can break the the chimney structure itself.
Soot Soldiers offers a range of chimney relining products. We will choose one that is perfect for your heating system. Relining a chimney requires proper sizing. Some companies will put in whatever liner fits, ignoring codes and national standards. We take the time to find out what is REQUIRED by your system, and then go from there.
