I just moved into a range-style house we just purchased. It is our first one and is a starter home located in the midwest.
Half of the basement is finished (very nicely I might add) with drywall and carpet. The carpet is directly on the floor (with a pad of some kind)-- no sub-floor.
The finished part is musty. It is not overly powerful, but it is definitely noticeable. There are really no signs of water/seepage anywhere in the basement. The unfinished portion doesn't seem to smell and seems dry and clean.
When we viewed the house, we just assumed that a dehumidifier would solve the problem (as it did in my college rental house...literally worked wonders by just running a couple hrs/day). The realtor (buyer's agent) didn't seem to think it was a big deal either and also thought a dehumidifier would work.
Well, the dehumidifier been running non-stop for 3-4 days now and has helped, but it is still musty. We are also running the A/C even though the outside is currently 65 degrees (with 85% humidity)
Also in the closing, the seller (stupidly) revealed that when they moved in 8 years ago, he had to refinish the basement because mold was growing on the drywall. He claims it is because there was no previous vapor barrier and that he put in such a barrier so we should have no such problems (must have been on his mind???). The seller seemed like an idiot...especially for revealing this in the closing. But now we know some history...
The home inspector didn't mention anything in the basement. However he did mention that the outside grading is not good at all, there are no window wells, and their are no downspouts for the gutter. Of course we plan on fixing these things as soon as possible and maybe this will solve the _causes_ of our must problem.
However I'm now very fearful of not being able to solve it. I'm thinking that maybe mold (!!!) is growing between the vapor barrier and the foundation wall. This would require tearing out the drywall I think. Or maybe that moisture comes up from underneath the basement and can't be solved without a sub-floor (not much headroom for one)
The market for homes in our area was terrible for this price range so we had to act quickly on this house. However we will definitely be selling in 4-5 years and I fear that as the market cools off, this must/mold situation cold make things very difficult for us or cold lead to costly repairs or even worse...
Any advice is greatly appreciated. I'm pretty worried about being royally screwed. Granted this is my first house and I'm jittery about it as is...
