Hi all, I had a carpenter fit new skirting boards in my house a few months ago. The walls were all newly boarded and skimmed. We had carpets fitted a month or so later after doing all the painting etc, and yesterday noticed that one of the carpets was wet near a wall underneath a radiator. After lifting the carpet to investigate, I eventually pulled off the skirting on that wall and found that one of the paslode nails used to pin the skirting is stuck in the wall, and presumably stuck in a radiator pipe - water is dripping out of the bottom of the wall directly underneath it. I think the nail went straight into the pipe and plugged it, because there was no leak for at least a month between skirting going in and the carpets going down. Then the carpet fitter has partially dislodged the nail when stretching the carpet, and it started to leak. I think it must have got gradually got worse since then. I'll have to cut into the plasterboard to expose the pipe and get a plumber to patch it up somehow. But that part of the carpet is sodden, and the supplier says it's likely to shrink and so would need to be replaced. In addition, there are two other rooms where the pipes run in the same position, and these have all had skirting fitted in the same way. I think it would be a miracle if the same thing hasn't happened elsewhere, since all the nails are pretty much in line with where the pipes must run. We should probably pull off the skirting in the affected areas and try to see if the same thing has happened elsewhere. I think the carpenter should have checked for pipes before nailing the skirting in, and glued it instead on these walls. I assume there is a tool for this. He also used 50mm nails, which seem unnecessarily long. A mitigating factor is that in one room, an old redundant pipe is visible running at the base of the wall. It's perhaps reasonable to see this and assume there were no other pipes? Though I think it would have been prudent to check anyway. He certainly should have checked in all the other places, or at least asked if we knew where the pipes were. Should the carpenter replace the carpet, if neccesary? I think at a minimum he should replace all the skirting we'll have to remove, and probably pay the plumber's costs. What are other's thoughts?
