I live in a condo with a unit below me. 5 years ago I installed engineered wood floors throughout my home, including bathrooms. I watched as the soundproofing material was put in place. Last year a new owner moved in below me. Her father is a contractor and did work in the unit. When he was doing some work in the bathroom I noticed warmth in the hardwood floor in front of my toilet. I notified him immediately, told him exactly where the area was and it was remedied. There is RECESSED LIGHTING THROUGHOUT the home below me. Periodically as I walk through my home barefoot I come across other areas where "warmth" is felt in the hardwood floors. They (he) swears they did nothing else that would cause the warmth. He also said there is no concrete between the floors (huh?). The HOA and my neighbor both tell me it's my problem - call out a plumber and see what's the problem. I live in So California - no radiant heat. I have marked the spots and taken pictures. I have area rugs around my home so I have no idea what's going on under them. I have lived here for over 30 years so I have a pretty good handle on my home and this building. All of my plumbing runs up into my ceiling. I am 99% sure this situation was not there when the previous owners lived there. Any suggestions or recommendations would be appreciated.
