From Millionaires' Row to Main Street
Spray Foam Insulation in Irvington serves a village of about 6,650 people on the Hudson, where Main Street climbs uphill from the train station to Broadway. The village counted about 1,180 single-family homes and 100 multi-family homes in 2018, plus co-op, condominium and apartment complexes totaling nearly 1,100 units. Survey data puts the median build year at 1956, with 28.5% of housing built before 1940.
Estates turned neighborhoods
In the Gilded Age, the estates along Broadway between Irvington and Briarcliff Manor were known as Millionaires' Row. After World War I some of them were subdivided into neighborhoods such as Jaffray Park, Matthiessen Park and Spiro Park. Houses on those streets range from large interwar homes to midcentury houses, each with its own insulation needs: big attics and kneewalls in the older ones, rooms over garages and cantilevers in the newer ones.
Main Street historic district
The Main Street area was added to the National Register of Historic Places in 2014, with 212 contributing buildings. If your house or building is in the district, check with the village before any exterior work. Most of what we do, such as attic sealing, basement rim joists and dense-packing walls from inside, does not change the look of the building.
Co-ops and condos
Irvington has thirteen cooperative complexes and eight condominium complexes, many built after World War II. In those buildings we work only where the owner controls the space and the board has approved the work. Top-floor units under a shared attic and units over garages are the most common calls.
Top-floor units and garages
In Irvington's postwar co-op and condo complexes, the most common complaints come from top-floor units under a shared attic and units over garages. The fix is the same as in a single-family house, sealing then insulating, but the work needs the board's approval because the attic or garage is often common space. We can provide a written scope and quote for the board to review before scheduling.
Hills and the river
Like its neighbors, Irvington is hilly and wooded, and houses on slopes often have one exposed basement wall. That wall and its rim joist are where closed-cell foam does the most good. The state energy code applies, with Westchester in Climate Zone 4.

Irvington Questions
Can you insulate a co-op or condo unit?
Where the owner controls the space and the board approves, yes. Top-floor ceilings and floors over garages are the most common jobs.
Will insulation work affect the look of a historic house?
Usually not. Attic, basement and dense-pack wall work happens from inside or through small patched holes. Check with the village before any exterior changes.
Can you give my co-op board a written scope?
Yes. We provide a written scope with materials, thicknesses and the areas involved, along with the price, for the board to review.
Do you work in Irvington's hillside neighborhoods?
Yes, throughout the village. Call (914) 785-6679 to set a visit.
