Mold, moisture and dirt basement
Project Location: Harwinton, CT
Basement appears dry but it is a concrete block foundation and there is a drain around the edge of floor that seems damp. Room was finished at one time but walls were moved to do re-wiring. My client wants an estimate on finishing the correct way so that it won't be damp.

We need to workout space in our house. The spare bedroom we're using is too small. Our basement has a concrete floor and walls and no drop ceiling. The stairs leading to the basement need to be replaced. We need moisture control, adequate lighting, a floor that's appropriate for exercising and mirrors on the walls.

Heres the deal: 1250 sq ft ranch. Basement is half 2 car garage the other half un finished basement. We do not get any water, but we do get a lot of moisture on the ground in the garage area and a constant musty /moldy area. We currently run a dehumidifier down stairs and pull about 100 pints a day. I would like to see if there is someway we can correct this issue withour spending an arm and a leg. Please help.
