How do I stop a reoccurring mold problem?
I have a client with a set of stairs leading to their finished basement. They have had a reoccurring issue with mold growth on the last few treads and risers. I have added a vapor barrier in the crawlspace behind, re-insulated the stairs with rigid foam and caulked or foamed every last crack. I’ve had these stairs apart twice now and after the last time (2 yrs ago) I thought I’d finally solved the problem. Unfortunately, I got the “it’s ba-ack” call last week. Any ideas?
