Spray Foam Insulation in Ardsley, NY

Spray Foam Insulation in Ardsley deals with younger houses than most of southern Westchester. Survey data for 2019 to 2023 puts only about 11% of the village's homes before 1940, and 15.3% were built in the 2010s, one of the highest shares of recent construction in the area. The median is still 1958, so the typical Ardsley house is a postwar Colonial, split or ranch, with some newer homes and townhouses mixed in.

Where postwar houses leak

Houses from the 1950s and 1960s were usually built with some insulation, but it is thin by today's standards and has settled. Their common problems are different from prewar houses: rooms over attached garages with cold floors, cantilevered floors over the foundation, kneewalls in second-floor rooms, recessed lights cut into the top-floor ceiling, and finished basements with uninsulated rims behind the paneling. Each is a contained job, and several together make a full-house plan.

Newer homes

A house built in the last fifteen years has better insulation, but it is not perfect. We still find rooms over garages with gaps at the bay ends, attic hatches that leak and spots where insulation was disturbed after inspection. If your newer house has one room that does not match the others, that is usually something we can find and fix.

The Saw Mill River

Ardsley sits along the Saw Mill River, and its Wikipedia history notes that recurrent flooding along the river has damaged residential buildings, with severe floods in 1980, 1984 and September 1999. Hurricane Agnes flooded the downtown in 1972. For houses on low ground, we check basements carefully for water history before insulating any foundation wall, and closed-cell foam is our usual material below grade because it does not absorb water.

Splits and raised ranches

The split-level and raised ranch are common in Ardsley, and both have the same weak spots. The upper level sits on a band joist over the lower level, and that band is often uninsulated. The room over the garage has cold air beneath it. Recessed lights in the top-floor ceiling let air into the attic. We seal and insulate each one, and those three fixes together usually even out the temperatures between levels.

Owners, code and permits

About 81% of occupied units are owner-occupied. Ardsley follows the state energy code, with Westchester in Climate Zone 4. Permits go through the village.
