Contractor says don't use dehumidifier
Hi all! I'm in dry, warm Southern California and I've just had a basement area finished. It was an unfinished open room off the garage, with one concrete block wall.
My contractor closed it off from the garage, added insulation to the ceiling (under my living room), can lights, and Drylocked then insulated/drywalled the concrete wall.
The concrete wall side is underground.
I ordered a dehumidifier for another purpose, but told my contractor I would use it in the new basement room too. He said it wasn't necessary, and not only that - it would draw moisture from outside INTO the concrete wall, new insulation, etc.
We've not had any moisture issues there previously, and this is a 30-y.o. townhome.
Any experiences? Do these dehumidifiers work so well that they draw moisture in from the outside like that?
I will listen to my contractor, since he's a smart cookie, but I am curious.
