crawl space insulation

winterh · 07-17-2015, 07:29 PM

Can someone recommend a local contractor who understands the proper way to insulate a crawl space. I bought a place last year with a dirt floor covered in plastic but not sealed tight. There is some insulation on the block walls but not every where. Batt insulation in the floor joists but sagging in places. I read an article about some crawl space horror stories that caused me to go under there and take a hard look. No obvious issues but definitely not done right. I have closed cell foam at home and was considering spraying the underside of the floor with that but am anxious to find out what works best.
