I have just purchased a house, and had a flooring co. in today for an estimate on new carpeting, which the entire house needs. The company said they charge extra for removal, so I sliced up the carpet & padding in the family room myself as a start, and removed it. The sub-floor, which is plywood, is filthy. Also, it has some rather large spots in the center that look like moisture stains, and seem to hold onto thick dirt more than other areas. The stains are a deep brown/gray in color. Are these mold? How do I rid the subfloor of this/disinfect it, in order to get new carpet laid on a few weeks? Can I use the bleach/dawn remedy, even on plywood? Do I have to replace the sub-flooring altogether?
My home inspection did not reveal any moisture in the crawlspace below – The inspector actually said the ground underneath was bone dry.
Ideas? Thx in advance.
