Question:

Dear Craig- I have a fireplace about 30 yrs old. It has a crack along the back firewall. Do I have to remove those plates and replace them- or can I use some kind of patching material. If I can use a patching material- what would you recommend. One last question: where can I find the name of the manufacturer on the fireplace? Thx for you help and time.



Answer:

Scott- I assume you are talking about a factory built "pre-fab" fireplace- otherwise known as zero clearance. Many times these are lined with plates of refractory clay- which can develop cracks over time. You do not need to replace the piece until it actually falls apart. There is a full metal wall behind that brick...so the panel is just a protector.You can purchase refractory cement or buff colored fireplace mortar in most stove shop or hardware stoves. Clean out the crack- wet it- and patch.<p>
Replacement panels can also be installed by many chimney sweeps. These panels are cut-to-size by the installer.
