Cupping Complaints

Wayne Lee Headshot

I woke up with a strange feeling … wet subfloors, wet subfloors, like a bad dream over and over. Then I got two phone calls with complaints about floors cupping and popping.

The AC pipes are dripping with water. I keep telling them to get air movement and shut down the crawlspace vents, but they all say the same thing ("I opened them to get more air.") Well, all that does is let in more outside high-RH air. (I feel like a broken record.)
