How do I find the source of a musty mildew smell?
We bought a house 3 years ago. I didn't have this issue for the first year and a half. My problem is , when you first walk into our home you get a strong mildew smell, just in the entrance way. We now , are starting to get it in the back bedroom closets. We don't live here yet, we are here every other weekend, until we retire. There is no evidence of damp areas. When we first moved in, we had the crawlspace redone with new insulation and automatic vents , everything has been painted, I had the sprinkler heads adjusted so they no longer hit the foundation of the house. Just a few months ago we installed a commercial dehumidifier in the crawlspace ( which has no odor ) we just pulled out and replaced all the old carpet and padding. The smell disappeared, but it was just the strong new carpet smell that masked the smell. I don't know if this has anything to do with the smell , but both areas back up to a slab....the entrance way to the front porch & garage. The back closets back up to the 3 season room that is on a slab...we need help !!! Anyone have some ideas ??? Even who to contact ???
