Seal Annandale Homes at the Source

Many Annandale houses—brick colonials, ramblers, and split-levels from the 50s–70s—leak air at the roof deck, rim joists, and over garages. Our team installs spray foam that expands in place to close those hidden pathways around framing, ducts, and penetrations so conditioned air stays inside. With the shell tightened, rooms track the thermostat more closely through humid summers and crisp winters, traffic noise along Little River Turnpike and the Beltway softens, and your HVAC runs shorter, fewer cycles. Whether it is an original attic, a carport conversion, or a two-story addition, we tune the scope so the comfort gains are immediate and durable.

Foam Types Matched to Each Assembly

Open cell foam is a strong air sealer that also calms sound in living spaces, making family rooms, bedrooms, and home offices feel steady and quiet. Closed cell foam delivers higher R-value per inch plus meaningful moisture resistance—ideal for garage ceilings with rooms above, band joists at the perimeter, knee walls in split-levels, and crawl spaces that benefit from added stiffness and vapor control near Accotink Creek's damp pockets. In attics we can treat the roofline to eliminate hot-and-cold swings; in tricky overhangs and dormers we bring stubborn zones back in line with the rest of the home. We specify type and thickness by assembly rather than forcing one product everywhere so performance is consistent across the house.

Clean, Code-Aware Install From Masking to Walkthrough

Every project begins with a clear scope and a site walk. We protect floors and finishes, establish ventilation during application, and apply foam evenly to the specified thickness and target R-values that meet Fairfax County requirements. Recessed lights, bath fans, and access hatches get the details that preserve airflow and safety, and we keep the jobsite organized from start to finish. When the work is complete, we tidy the space and review what was installed so you know exactly what to expect on day one. Our crew serves Annandale Acres, Broyhill Crest, Canterbury Woods, and surrounding neighborhoods with straightforward communication and results you can feel the first week.
