Brand new house...but basement VERY humid
WE just moved into our new construction house the end of April. Shortly after we moved in we noticed that the basement felt very humid. We put some of our cardboard moving boxes down there and after a few weeks we were down there and they almost felt damp to the touch..you could feel the moisture in them. We mentioned it to the builder (we have a 1 year warranty) but he didn't think there was a problem. We have a dehumidifier that we run constantly. Because we don't have a drain, we need to manually empty it. We empty it every morning before work and it is full (and shut off) when we get home. On the weekends we can empty it (from full and shut off) at least 3-4 times per day. I don't have an exact listing, but I think it holds about 1 gallon of water. Yesterday I decided to move some things around and found a couple bags with mold growth on them. They did not have mold when we moved them less then 4 months ago. I contacted the builder and am waiting to hear back. Does anyone have any input on what we should do? I'm debating on contacting a professional myself and see what they say and then let the builder know. I also thought about getting a 2nd dehumidifier. The sq ft of the basement is approx. 1300. We do not have gutters and noticed that we have a "trench" around the perimeter of the house from where the rain falls. We also had some water in the basement during our walk-through that appeared to come from the bulkhead, but that was fixed.
