How to carefully remove brick raised heath
I need to rebuild a brick raised hearth for my fireplace and was wondering what the best way to demo the existing hearth: 1) Safely, and 2) without damaging the face of the fireplace, which is also brick. Are we talking chisel and masonry hammer? Thanks!

an electric chipping gun works the same but does it much faster,,, IF you're worried about the f/p face, use a 4" grinder & diamond blade to saw an isolation kerf

Thanks guys. One more question, I'm going to rebuild the raised hearth (slightly smaller) and it's going to have a granite slab on top of it and stone veneer on the sides. Approx 18" x 48", 2" thick. Not sure what it weights but it's obviously heavy. What kind of structure am I going to have to build to rest this on? I was thinking about constructing something out of 2x6s, then putting 3/4" ply and cement board on the sides. Should I put plywood & cement board on the top as well? With this frame be strong enough for the slab? Thanks!

IF what's supporting the hearth now is sufficient, i wouldn't think you need worry about what's underneath,,, your plan sounds fine BUT remember little people ( AND big people, too ) often have desires to sit upon hearths :yes: granite has little flexural strength so keep that in mind,,, no sense in expending all your time/$ only to see your fat brother-in-law sit on it then hear it crack :no:
