Before and After Pictures from Arlington
Basement Spray Foam in Arlington, VA

Basement Spray Foam in Arlington, VA

Before After
Basement Spray Foam in Arlington, VA Basement Spray Foam in Arlington, VA

This Arlington, VA homeowner was remodeling their home and wanted to use spray foam for their basement. Comfenergy recommended a closed cell spray foam without a thermal barrier for this project.  This type of spray foam was used for its ability to be a vapor barrier.  Also, the spray foam was being covered up by drywall, so there was no need for a thermal barrier.

We need some insulation above our garage ceiling and around some air vents in our attic.
in Arlington
We have a 1937 brick cape cod with a large crawl space beneath our front bedroom. We had the space re mediated for mold several years ago and tried with foam board and fiberglass rolls to insulate it ourselves. I'm afraid we didn't do a very good job. Also, the concrete floor is cracked in places and needs to be repaired or replaced, as there are cracks that go all the way to the bare ground and once a small plant even grew up through one. Help!
