Spray Foam Insulation in Great Kills, NY

Spray foam insulation in Great Kills deals with houses near water in more ways than one. Wikipedia explains that kill is an old Dutch word for creek or channel, and many small streams run through the neighborhood. Great Kills Harbor forms its southern edge. Like other East Shore neighborhoods, it was mostly rural with shoreline resorts until the 1950s, after which the Verrazzano-Narrows Bridge brought heavy residential growth from Brooklyn.

Houses from the growth years

Most homes here were built from the 1950s through the 1990s: capes, ranches, raised ranches, colonials and townhouses. Typical gaps are thin attic insulation, open bypasses around plumbing and wiring, bare rim joists and poorly insulated rooms over garages. Capes with half stories have kneewalls that run hot in summer and cold in winter.

Water nearby

With streams and the harbor close, some basements and crawl spaces run damp. We check for moisture, staining and standing water first. Closed-cell foam on the rim joist and foundation walls keeps humid air off cold surfaces, and a vapor barrier helps in crawl spaces. Near the harbor, we also ask whether the house is in a mapped flood zone, since that limits materials below the flood elevation.

The size of the area

Wikipedia's census summary for the Great Kills-Eltingville tabulation area shows 54,699 residents in 2020, with 22.9% of occupied units rented. Most of our work here is for owner-occupants improving houses they plan to stay in.
