Insulation built for Putnam County homes

Sebastian Spray Foam is a Brookfield, CT insulation contractor working in Putnam 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 Putnam County homes. Homes around Putnam County 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 Putnam County homes are built like

Putnam County runs from Carmel and Brewster near the Connecticut line to Cold Spring on the Hudson: lake communities, older village homes and newer colonials on wooded lots, most with the vented crawl spaces and open attics that lose heat through a Hudson Valley winter.

Working in Putnam County

Putnam is a short drive from our Brookfield shop across the state line. The work follows the house: moisture control under the lake homes, attic air sealing and insulation on the hills.

Questions from Putnam County homeowners

Do you work in Putnam County?

Yes. Sebastian Spray Foam is based on Federal Road in Brookfield, CT and works across Putnam County, New York, including Putnam County and nearby Westchester County, Dutchess County and Danbury. Call (203) 546-7800 or request an estimate and we will set up an in-home assessment.

Why are the floors in Putnam County homes near the water so cold?

Cold floors and musty air usually start under the house. In a vented crawl space or at an open rim joist, damp outside air moves up into the living space. Closed-cell spray foam on the crawl space walls and rim joists blocks ground moisture and the drafts that come with it, which is why it is the material we specify there.

What happens when I request an estimate in Putnam County?

First, an in-home assessment: we inspect your attic, walls or crawl space and find where the house is leaking energy. In Putnam County that usually means the crawl space and rim joists first, for the moisture, and then the attic. Then a clear quote, with the right material for each space, the same way we quote in Westchester County, Dutchess County and Danbury. Then the install: our own crew seals the envelope, protects your home throughout, and leaves it spotless, anywhere in Putnam County.
