Spray Foam Insulation in Sherman
Sherman is the quiet northern end of Candlewood Lake, a farm-and-lake town with fewer people than any other in Fairfield County. Its homes are spread out, many of them older, and most were never built to hold heat through a hill-country winter.

Insulation built for Sherman homes
Sebastian Spray Foam is a Brookfield, CT insulation contractor working in Sherman and across Fairfield 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 Sherman homes. Homes around Sherman 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 Connecticut season, with lower bills to match.
What Sherman homes are built like
Sherman's housing is a mix of lakefront cottages and year-round homes on Candlewood's northern shore, antique farmhouses and colonials along the old town roads, and newer houses set back on large wooded lots. Converted lake cottages tend to sit over vented crawl spaces; the farmhouses lose heat through fieldstone foundations and attics that have been added onto more than once.
Working in Sherman
Sherman is about 25 minutes up from our Federal Road shop. The lake houses need the moisture handled under the floor first, while the farmhouses up in the hills are mostly an attic and foundation job.

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