Spray Foam for Arlington's Mix of Homes

Arlington blends brick colonials in Lyon Village, bungalows along Columbia Pike, and townhomes near Ballston, Clarendon, and Rosslyn. Many of these homes leak at the roof deck, along rim joists, and around additions that created rooms over garages. Our team installs spray foam that expands in place and closes the thin pathways around framing, ducts, and penetrations so conditioned air stays inside. With uncontrolled air movement reduced, upstairs rooms hold steadier temperatures through humid Potomac summers and cold snaps off the river, and interiors sound calmer near I-66, the GW Parkway, and under the Reagan National flight path.

Attics, Over-Garage Rooms, and Tricky Short Slopes

Top floor comfort in Arlington often improves fastest at the roof deck. Converting a vented attic to a properly detailed unvented assembly brings second floors in line with the thermostat and reduces the conditions that lead to winter heat loss. Rooms over garages in North Arlington become part of the conditioned shell when the lid, knee walls, and rim areas are treated as a connected system. Short sloped ceilings, dormers, and attic returns common in post-war layouts also benefit from foam, since the material creates a continuous thermal and air barrier in spaces that are hard to seal with traditional products.

What Changes After Installation

You can expect fewer temperature swings from morning to night, less street and aircraft noise in exterior rooms, and shorter HVAC run times because the shell is no longer leaking behind the scenes. Dust tracks ease as well, since the same gaps that moved air were carrying fine particles through the envelope. Homeowners across Clarendon, Ballston, Cherrydale, Pentagon City, and National Landing usually feel the difference within the first week.
