After having the dehumidifier running non-stop in the crawl space

Q: You were kind enough to give your opinion on our floors last fall. Now we’ve given it several months, with a dehumidifier running non-stop in the crawl space. The floors have gone down some, but there is still a noticeable cup. Continue reading After having the dehumidifier running non-stop in the crawl space
