So I was preparing the living room recess at the side of the chimney breast for soundproofing, attaching battens to the wall when I discovered that I had drilled into a gas pipe, (feeding the gas fire), hidden low down in the wall, above the skirting board, but under the plaster. The emergency gas man told me this was an unusual place to locate it.... Step 1 is obviously to get someone to repair the pipe. But step 2? Can I just attach the soundproofing materials and plasterboard over the pipe or will I need to bring the pipe out of the wall completely?
