Hello, I have an issue with, what is to believe, molding on the corner wall in my bedroom during winter season. Its odd that I don't see it during summer but only during winter and especially at the same location every year. Now it looks like its heading to the corner ceiling. Am I right to say that there is a leak behind the drywall? Or is it just trap moisture? There is a wardrobe there occupying the space which is also catching mold. I have been using a mold spray product which gets rid of it but does respawn the next season. What are my options when it comes to eliminating this mold-fessed corner? Should I check the attic (insulated filled) for leaks? Is it something that just require deeper cleaning? I don't want to tear down the walls if possible as that would be my very last option if it comes to it. Since I'm discussing molds, I have mold around my window frames due to condensation on the windows, I believe, and the water is leaking down. Is there any solution for that? I notice no other new windows installed there are mold, even especially in the basement. Any and all response are greatly appreciated. Thank you.
