Dampness on inside wall
Posted: Wed Oct 31, 2012 9:21 am
We discovered a problem, not sure where it's from. There was a musty smell coming from one of the kid's bedrooms. There is a double bed in that room, it's one of the high mattress types, and it was up against an outside wall lengthwise. Pulling it away from the wall we discovered what looks like condensation on the wall, and the bed sheets felt damp where it was up against the wall. There was a bit of green mold along the baseboard, but none on the bed or anything.
There is another, identical bedroom along the same wall, so we inspected that one, and no problem there, although it has a different kind of bed with a thinner mattress, and no box spring (it's a "captain's" bed with drawers along the bottom).
My question is, is what we're seeing condensation from interior humidity? And because the big bed was there, it acted like an insulator? Sort of like if you put a vapour barrier on the outside of a wall instead of the inside? I can't find any evidence of leaking through the walls from rain, and if it came in that way I would expect to see black mold, not the surface green mold... sound right? I'm not sure why this would happen unless her wall isn't insulated well or something.
Has anyone ever experienced something like this before, and is there a solution other than leaving a gap between the bed and the cold wall? (limited space as it is)
