We have moved into house whuch has marble fire surround and basket in it with artificial coals in it. It was formerly a gas fire but had been capped off by previous owners. We were advised to get chimney sweeped and then had bew chimney pot put on which we have done. The issue is with the next step. We seem to be receiving different advise and wondered if anyone csn assist? One guy said he needs to see photos of the fire but that it may be that whole fire surround has to come off. I can't believe it. He said something about heat of fire could crack it. The floor around fire is concrete in black. Any advice greatly appreciated. Cheers
