A more comfortable building starts with a tighter shell. Our Bethesda crew installs open and closed cell spray foam that expands in place to close gaps around framing, ducts, and penetrations. By reducing uncontrolled air movement, rooms hold temperature more evenly through humid summers and chilly winters, dust and street noise drop, and your HVAC does not have to work as hard. From a single bonus room to a full roof-deck application, we size material and thickness to your goals, budget, and local code so results are noticeable right away and durable over time.
The Right Foam for Each Assembly
Open cell foam is a strong air sealer that also helps with sound control in living areas, making family rooms, bedrooms, and home offices feel calmer. Closed cell foam delivers higher R-value per inch and meaningful moisture resistance, which is ideal for garage ceilings with rooms above, rim joists at the perimeter, and crawl spaces that benefit from stiffness and vapor control. In attics, a roof-deck application can smooth out hot and cold spots; at the band joist it stops the perimeter leaks you can feel near baseboards; and in tricky overhangs or knee walls it brings stubborn spaces back in line with the rest of the home. We match foam type and thickness to each assembly rather than using one material everywhere, so performance is optimized across the house.
Clean, Professional Installation—Start to Finish
Every project begins with a walkthrough and a clear scope. We protect floors and finishes, ventilate during application, and apply foam evenly to the specified thickness and target R-value. When the work is complete, we clean the space and review results with you so you know exactly what was installed and what to expect from day one. Our team serves Downtown Bethesda, Edgemoor, Westmoreland-area blocks, and nearby neighborhoods with the same careful approach: clear communication, code-compliant materials, and a tidy, respectful jobsite from start to finish.
