Over an extended period of time, moisture collects in traditional clay and mortar chimney liners - making them susceptible to deterioration.

When your chimney's innermost liner membrane begins to break down or crumbles - you become vulnerable to hazardous carbon monoxide poisoning or a structure fire that can do significant damage to your home.

Rebuilding a liner will make your chimney safe again. However, rebuilding a liner can be very costly.

That's why installation of stainless steel replacement liners have become so popular. Not only are stainless steel liners more economical as a replacement, they're also easier to maintain and thought to be a bit safer.
