A huge amount of dirt and soot can be discharged from an old fireplace upon reopening it for renovation. A decent Castleford fireplace fitter will bring dust sheets to cover up your furniture and supply a bit of protection, but it's wise where possible to remove furniture and carpets from the room before work begins. If you're lucky enough to be working on a full home restoration project then it should be one of the initial jobs to complete before re-plastering and decorating the walls. This helps prevent any staining damage to any restored work you have already completed.
