Kitchen pipe flooded bedroom - should GC replace carpet?
Tuesday night, I walked into my daughter's room and stepped into a puddle in the carpet. The carpet was really wet all along the 12' wall between the kitchen and the bedroom. (We went through several bath towels trying to soak up the water.) When our GC opened up that wall yesterday, he discovered that the cabinet guys (who I hired directly) put a nail through one of the pipes. The water ran down the wall and under the carpet on the bedroom side. The kitchen has tile on slab, so no water came through there. (I just had a terrible thought - we may need to pull the toe kicks off the cabinets to make sure there is no water under the cabinets, which sit on the tile.) GC removed several sections of drywall from the bedroom side and is running fans to dry out the space.
This is a brand new wall installed by GC with new plumbing work done by GC's sub. There was no metal plate put in between the pipe and drywall to warn anyone trying to put a screw or nail through the wall that there were utilities there, so I have a hard time blaming the cabinet installer. If the plumbers had paid attention to the cabinet layout shown on the building plans, they should have realized it was a stupid place to put the pipe. Someone, the plumber, framer (GC) or drywall guy, should have put up a metal plate to shield the pipes before installing drywall and hiding them.
The bedroom is 11' x 12' and had new carpet installed 6 months ago. GC pulled back a 12' x 5' section of the carpet and removed the pad underneath so the carpet can dry. He put the section of pad outside to dry. DH thinks it will be fine to put the same pad back in in a few days and stretch the carpet back over it. Since it was only wet for one day and it was clean water, he is not worried about mold or mildew. The pad we used was the most expensive pad upgrade with antimicrobial treatment, which the store recommended for people with pets and small children. The carpet is a Stainmaster carpet. I am concerned that all of the water may have washed the stain-resistant coating off of the carpet and/or the mold-resistant chemicals out of the pad, thereby shortening the useable life of the carpet. We have the same carpet in 5 rooms and my experience is that carpet colors/patterns available from a manufacturer change regularly, so we may not be able to re-carpet the one room in a few years if we need to and still have it match the other rooms.
Am I worried for nothing? I do not want to ask the GC to replace the pad (and maybe the carpet too) if it is not really necessary. There have been other problems with subs on this job, and I don't think he is making much money on it at this point. Plus, we would like to get the room back to normal as soon as possible.
