Spray Foam Insulation in Katonah
Katonah is the village that moved: in the 1890s, when New York City's reservoir system was set to flood the old hamlet, many of its houses were rolled to the present site beside the railroad. Today it's a walkable village of Victorians around the Harlem Line station, with Caramoor and the John Jay Homestead just outside.
Insulation built for Katonah homes
Sebastian Spray Foam is a Brookfield, CT insulation contractor working in Katonah and across Westchester County. We install open- and closed-cell spray foam, attic, crawl space and rim joist insulation, air sealing, blown cellulose and fiberglass, and batt insulation in Katonah homes. Homes around Katonah lose the most energy where you can't see it, the attic, the rim joists, and the gaps inside finished walls. Our licensed, insured crew seals those leaks so your home holds its temperature through every New York season, with lower bills to match.
What Katonah homes are built like
Katonah's village streets are lined with late-Victorian and early-1900s houses, some of them the same homes moved in the 1890s, while the roads outside the village hold colonials, farmhouses and estate homes on large lots. The village houses are mostly balloon-framed with plaster walls and little or nothing in the wall cavities; out on the larger lots, the estate homes have a great deal of air to keep warm, and every leak in the shell adds to it.
Working in Katonah
Katonah is about 40 minutes from Brookfield by I-84 and I-684. In the village the work is done from the inside, in the attic, the basement and the closed walls, so the old houses keep their character.

Questions from Katonah homeowners
Do you work in Katonah?
Yes. Sebastian Spray Foam is based on Federal Road in Brookfield, CT and works across Westchester County, including Katonah and nearby Bedford Hills, Bedford and North Salem. Call (203) 546-7800 or request an estimate and we will set up an in-home assessment.
Can you insulate an older Katonah home without opening the walls?
Often, yes. Dense-packed cellulose fills closed walls without opening them, and the attic and rim joists can be air-sealed and insulated from inside. Where a renovation already has the walls open, spray foam seals the cavities before the finishes go back. We look at the house first and recommend the material that fits it.
What happens when I request an estimate in Katonah?
First, an in-home assessment: we inspect your attic, walls or crawl space and find where the house is leaking energy. In Katonah that usually means the attic, the basement or cellar, and the closed walls, worked from the inside so the original detail stays put. Then a clear quote, with the right material for each space, the same way we quote in Bedford Hills, Bedford and North Salem. Then the install: our own crew seals the envelope, protects your home throughout, and leaves it spotless, anywhere in Westchester County.
