Made for Alexandria Rowhouses and Townhomes

Old Town brick rows, Del Ray duplexes, and West End townhomes have tight cavities, party walls, and low-slope roofs that let air leak in hard-to-reach places. Cellulose is blown as a fiber-rich fill that flows around pipes, wiring, and uneven framing, then locks together to slow air movement inside the assembly. Treated with borate for fire resistance and long-term pest deterrence, it adds control without opening finished rooms or changing historic exteriors. The payoff in Alexandria is immediate: steadier rooms during humid Potomac summers and winter snaps, and a calmer sound profile under the Reagan National flight path and along Duke Street.

Attics and Low-Slope Roofs—A Better Lid on Comfort

Most comfort loss starts at the top of the house. We prepare the attic by closing obvious bypasses, setting vent chutes in cornice bays to keep airflow where it belongs, and insulating plus weatherstripping the scuttle or pull-down stair so access is not the weak point. Then we install an even cellulose cap across the field, mark depths for verification, and build raised service platforms where storage is needed so the blanket is not crushed. On short slopes and dormers common to Alexandria rooflines, we use a net-and-blow method to create dense, gap-free coverage that tames the hot-cold swing that makes top floors hard to live in.

What You Notice Afterward

Bedrooms that lagged behind finally track the thermostat, hallway floors feel less chilly on windy winter mornings, and street and aircraft noise drop a notch. Because uncontrolled air movement is reduced, equipment typically cycles less often and for shorter bursts, trimming energy use and wear. Dust routes ease too, since the same cracks that moved air were carrying fine particles through the shell. It all adds up to a quieter, steadier envelope that makes day-to-day living in Alexandria more comfortable.
