How to test for mold in basement?
If you've had problems with water damage in your basement before, there is a really good chance that you have mold. The downside is, it can be hard to detect mold on your own since it can grown within the walls or under carpet. You can buy a mold test kit from somewhere like Home Depot to check on your own. I would probably start there if I were you and if you see you have a problem, then I would probably call a professional. Especially if you've noticed a decrease in air quality in your basement.
