How do you fix a moldy basement smell?
I live in Sudbury Canada in a 1959 bungalow and the basement is always humid and the dehumidifier runs constantly. It also costs a fortune to heat. I was advised to insulate the top portion of the foundation (the top third) but the wall is not insulated at all. And on the bottom of the walls there is a white powder. According to what I am told, the problem is from excess moisture and probably due to french drains that aren’t working anymore. A contractor gave me a price for excavating the outside and replacing the drains but that is very expensive. Someone else told me to install a sump in the basement instead which would cost much less, will that do it? After fixing the problem I want to insulate the basement so I’m hoping for some advice. Thank you.
