I found the source of my mold smell. I guess I should have pulled the overhead cushion back further before buying my 1993 Seabreeze. I probably would have bought her anyway though.
Here is what I can see. Window leaking under wall paper and dripping into the seam. Seam is mushy. The actual wall still feels solid, but the wallpaper is no longer adhered to the wall.
Is there any way to put a stop to this without tearing anything out? I was thinking about caulking the window and caulking closed the smelly seam. Is this a bad idea? Does anyone know how much this might cost to have it professionally repaired or how difficult it would be to cut out the moldy part? Hopefully the part that needs to be removed, if any, is the bed under the cushion near the wall and not the wall itself.
Thank you for any help!
