Hello, I have tried searching the archive and tried looking up stuff in the Building Regs, but with no luck. Please, does anyone know whether it is OK to cut into 7" deep joists (to run 2 22mm pipes across them) without reinforcing the floor? My installer yesterday did this. It looked as though he was taking enormous chunks out of the joists. Now in one corner, when I steppe on it to clear up this morning, the floor moved a bit, the pipes under the floor at the point rattled and the radiator about 15' away on the other side of the room made a noise. Is the floor dangerous?
I phone the local Council's Building Regs people and was told you can't cut into a 7" joist without reinforcing it. I have tried to check out this information but couldn't find anything. The Building Regs man said it would be a good idea to get an independent Structural Engineer out: before I do this I thought I'd speak to people here. Of course I shall get the engineer if it's necessary becasue I can't have the floor collapsing. The job was done by a Warm Front installer, by the way, so I had no choice of the firm.
