Hello,

I recently bought a house that has all the main bedrooms in the basement.
You can see the foundation wall in all of the bedrooms. It acts as a ledge.
All the walls are finished and there appears to be drywall overtop of the
foundation wall.

My question is that I have noticed a soft spot on one of the foundation
portion of the wall in one of the bedroom (the drywall on the foundation
wall) and I am not sure what I should do about it. The soft spot is under
the window and above the electric baseboard heater. It doesn't feel
symmetrical. I'm not sure how to describe it...it's like as if the gyp-rock
has gone away (dissolved?) leaving the paper part of the dry way.

The soft spot doesn't appear newly formed. There is no sign (smell, touch,
or sight) of mold. I have an 17L (30 pint) dehumidifier with digital RH
meter set to 60%.

I'm not sure what or if I should do anything about this? What could be some
possible causes for this? And what action(s) should I be taking.


Thank you,

Alvin
