We have a pipe that bangs for a while right when we turn the heating on. I managed to isolate where the pipe is (under the floorboards on one room), the problem is that I can't lift the floorboards because they go under a built in wardrobe, and I don't want to cut them in case I hit the pipe.

I read that an idea could be make a hole on the floorboard right on top of the pipe (I'll need to figure out how to do it without hitting the pipe) and just inject insulation foam, but I'm not sure about this method.

Has anybody have any suggestion or similar experience?
