Spray Foam Insulation in Patterson
Patterson is Putnam County's northeast corner, a town of farmland, the Great Swamp and the lake community at Putnam Lake, right on the Connecticut line. It's quiet, open country, and the homes feel every bit of the wind.

Insulation built for Patterson homes
Sebastian Spray Foam is a Brookfield, CT insulation contractor working in Patterson and across 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 Patterson homes. Homes around Patterson 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 Patterson homes are built like
Patterson's homes include the bungalows and cottages of Putnam Lake, many built as summer places and later winterized, along with farmhouses in the valley and colonials and raised ranches on the hills. The winterized bungalows usually have little insulation in the walls, low attics and crawl spaces open to damp air.
Working in Patterson
Our crew comes over through New Fairfield, a trip of roughly 35 minutes. Near the Great Swamp and the lakes, moisture under the house is the first thing to fix; the hilltop homes are mostly an attic and air sealing job.

Questions from Patterson homeowners
Do you work in Patterson?
Yes. Sebastian Spray Foam is based on Federal Road in Brookfield, CT and works across Putnam County, including Patterson and nearby Brewster, Pawling and New Fairfield. Call (203) 546-7800 or request an estimate and we will set up an in-home assessment.
Why are the floors in Patterson 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 Patterson?
First, an in-home assessment: we inspect your attic, walls or crawl space and find where the house is leaking energy. In Patterson 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 Brewster, Pawling and New Fairfield. Then the install: our own crew seals the envelope, protects your home throughout, and leaves it spotless, anywhere in Putnam County.
