Around Hull, Colbert and Danielsville many properties have a barn, shop or poultry house next to the home. Closed-cell spray foam on metal panels stops condensation and drafts, so we size commercial work and residential work in the same visit.
The Census median year built for Hull homes is 1993, so many attics still have the original vented layout and settled blown-in insulation. Those homes often benefit most from air sealing plus a roof-deck or attic-floor upgrade.
