Why Cellulose Works for McLean Homes

McLean’s mix of large colonials, custom infill, and river-influenced estates often hides small air paths at roof edges, knee spaces, and the band joist. Blown-in cellulose flows around wiring and irregular framing, then locks together to slow air movement inside the cavity. The fiber is made from recycled content and treated with borate for fire resistance and long-term pest deterrence. Packed to the correct density, it resists settling, softens roadway noise from the Beltway and the GW Parkway, and helps bedrooms track the thermostat through humid Potomac summers and crisp winter mornings along Old Dominion Drive and Chain Bridge Road.

Attic Caps and Dense-Pack Retrofits, Done Cleanly

A stable upstairs begins with a continuous lid. We seal top plates and open chases, set soffit baffles so ventilation stays clear, and insulate plus weather-seal the hatch before blowing a level cellulose blanket from corner to corner with depth markers for easy verification. On low slopes, dormers, and complex valleys common to McLean roofs, we add wind-wash protection so outside air does not scour the perimeter. Finished exterior walls are tightened from the interior through small access points and dense-packed so the fill wraps outlets and pipes and stays put. Short sloped ceilings and knee walls over garages are netted and blown to a precise pounds-per-cubic-foot target, which brings bonus rooms and lofts in Salona Village, McLean Hamlet, and Ballantrae back in line with the rest of the home. If the attic already has dry fiberglass, a cellulose overlay suppresses internal air looping and raises total R-value without a tear-out.

Local Compliance, Tidy Work, Visible Results

Our scopes reflect Fairfax County requirements and common HOA expectations, and we protect hardwoods and finishes from setup to sweep-up. Recessed lights receive rated covers or safe clearances, bath fans are sealed and ducted outdoors, and rim or masonry interfaces get targeted air sealing so heat and air do not bypass the upgrade. When we finish, you receive documentation of installed depths and densities for your records. Most homeowners notice steadier temperatures upstairs, fewer drafts near baseboards, a quieter interior in rooms facing Tysons or the Parkway, and shorter HVAC run times because stray airflow has been reduced.
