Spray Foam for Fairfax Homes—Comfort You Can Feel

Fairfax has a little of everything: 60s and 70s colonials in Mantua and Mosby Woods, townhomes near GMU, and newer builds around Fair Oaks and Fairfax Corner. Across all of them, comfort improves fastest when the building shell stops leaking air. Our crew installs spray foam that expands in place and closes the hairline gaps around framing, ducts, and penetrations. With uncontrolled air movement reduced, rooms track the thermostat more closely through humid summers and chilly winters along I-66 and Route 123, everyday dust pathways calm down, and the house sounds quieter even during busy traffic hours.
Open Cell vs. Closed Cell—Matched to the Assembly
Instead of one material everywhere, we match foam type and thickness to each area of the house. Open cell is excellent for rooflines and living areas where you want strong air sealing plus sound softening—great for bonus rooms and home offices near Fairfax Boulevard. Closed cell delivers higher R-value per inch and meaningful moisture control, which makes it the right choice for rim joists, over-garage floors with bedrooms above, and tricky knee walls or dormers that never hold temperature. If you are converting a vented attic to an unvented assembly, we design the approach to meet code and protect ventilation pathways, so the upgrade performs year-round without creating new issues.
Attics, Over-Garage Rooms, and Bonus Spaces
Fairfax homes often lose the most comfort through the lid of the house and over the garage. At the roof deck we can create an unvented, insulated assembly that smooths out hot and cold swings and helps upstairs rooms feel consistent from morning to night. Over-garage rooms that were always a step behind the thermostat become part of the conditioned envelope when the garage lid and adjoining knee walls are foamed as a system. Dormers, short slopes, and attic returns by the stairs get the same attention, and we weatherstrip and insulate the hatch so the new performance is not undercut at the access point.
