My basement smells all the time and I am trying to find an actual solution that will work. The basement is finished with a walkout with two windows, a suspended ceiling and concrete floor. The ceiling tiles I am going to replace since they are old and are sagging. And I want to paint the floor with an epoxy basement sealing paint. But I am not confident that either will 100% get rid of the smell. I am going to get a dehumidifier this weekend and see if that starts to help.
