I recently bought a house and this weekend I went to start a fire. When I did this I found that there is a gap of about 6" between the brick and wood framing for the fireplace mantle. This poses a severe fire risk as burning hot amber could roll into that gap and start my house on fire. This gap is all the way around and the only option I can see would be to tear out some framing and brick to the opening but I wanted to get some suggestions. Any help would be appreciated.
