Here is the situation I am faced with. I had a hardwood floor installed on top of concrete almost 2 years ago. Last year, the floor started buckling and I asked my contractor to tell me what was wrong and to fix it. He told me I should have put a rug down on the floor so that it wouldn't absorb moisture from the air. He also said that he might not have left enough room for expansion of the wood, so he cut a strip of wood off one side of the floor where most of the buckling was happening. The floor continued to buckle and I noticed it happening in other places as well. He then came back and resanded the floor, then put two coats of finish on it. This was about 2 months ago. 1 month ago, i noticed that some of the boards have started to blacken, when i look closely, i see mold spores -- both white and black. I'm very concerned and need to tell him what to do. When I ask him, he said he didn't know what the problem was. This is how he laid down the floor: Nailed a plywood subfloor on the concrete, laid down paper on top of the subfloor, then laid down the hardwood (beautiful red oak!) -- the hardwood was not prefinished hardwood. I am looking for an expert to help me so that I can tell him what needs to be done. Please help!! A friend told me that it sounds like he didn't install a vapor barrier, could that be the case?
Thanks so much,
Indira
