Spray Foam That Matches Chantilly's Homes

Chantilly's neighborhoods include Westfields, Pleasant Valley, Franklin Farm, and communities along the Route 28/50 corridor. The area mixes 1980s colonials with newer townhomes and additions. Common comfort issues include thin roof decks, leaky rim joists, and over-garage bonus rooms that never feel like the rest of the house. We install spray foam that expands in place and closes hidden pathways around framing, ducts, and penetrations. Once uncontrolled air movement is cut off, upstairs spaces stop swinging with the weather, traffic and aircraft noise from the Dulles corridor softens, and the whole house feels tighter and easier to condition.
Open Cell or Closed Cell: Chosen by Assembly, Not Habit
Open cell foam is excellent for deep air sealing at the roofline and in living areas where sound matters, including family rooms, bedrooms, and home offices. Closed cell foam delivers a higher R-value per inch and real vapor resistance, which makes it the right call for garage ceilings with rooms above, band joists at the foundation, low-slope dormers, and crawl or storage bays that tend to run damp. In many Chantilly homes we pair the two: open cell at the roof deck to tame upstairs temperature swings, and closed cell at rims, short slopes, and tricky overhangs so those trouble spots stop bleeding comfort. Every area gets the chemistry and thickness that meet Fairfax County requirements and your performance goals.
High-Impact Upgrades for Chantilly Layouts
Two locations usually deliver the biggest win: the roof deck and the garage lid. Converting a vented attic to a properly detailed unvented roofline smooths out the hot and cold cycle that makes second floors hard to live in. Foaming the garage ceiling as a system with adjoining knee walls and rim areas brings bonus rooms and FROGs back in line with the rest of the home. We also address short sloped ceilings, dormers, and band-joist perimeters that leak on windy days along the 28/50 corridor, giving you a tighter shell and a quieter interior from day one.
