Spray Foam Insulation in Tarrytown, NY

Spray Foam Insulation in Tarrytown covers a village of about 11,900 people on the east bank of the Hudson, roughly 25 miles north of Midtown. Survey data for 2019 to 2023 counts about 5,650 housing units with a median build year of 1955; 28.8% predate 1940 and another 10.8% went up in the 1940s. About 57% of occupied units are owner-occupied, and the rest are rentals, from older multi-family houses to newer apartments.

Historic districts

Tarrytown has protected its older streets since 1979, when the village board created historic districts to stop large-scale demolition. The North Grove Street Historic District is on the National Register. Estates like Lyndhurst, on the Tarrytown and Irvington line, are famous, but most historic houses here are ordinary village homes. Insulation work in those districts should not change how a house looks, and we keep it that way: attic and basement work from inside and wall work through small, patched holes.

What changed and what stayed

Mid-twentieth-century urban renewal cleared parts of the waterfront and lower Main Street, replacing older houses with public housing, parks and boat basins, and the original Tappan Zee Bridge opened in 1955. That leaves a village where nineteenth-century houses on the hillside streets sit near postwar buildings. The older ones need attic sealing, rim joist foam and wall filling. The postwar ones need attention at rooms over garages and in finished basements.

Wind off the river

Houses on the hillside above the river take the wind, especially in winter. Exposed basement walls and rim joists on the downhill side, and top floors with windows facing the water, are where comfort complaints start. Closed-cell foam at the rim and sealing at the attic floor go a long way.

Rentals and multi-family houses

About 43% of occupied units in Tarrytown are rented, and many are in older multi-family houses near the village center. Sealing the shared attic and basement helps every unit and often reduces complaints about uneven heat. We schedule foam work for times the building can be cleared and do sealing and blown-in work with tenants home.

Code and permits

Tarrytown follows the New York State energy code, with Westchester in Climate Zone 4 and R-49 listed for ceilings. Work that needs a permit goes through the village building department.
