Spray Foam Insulation in Greenwich
Greenwich holds some of the oldest and largest homes in Connecticut, most built long before anyone thought about air sealing. Stone colonials, converted carriage houses, and waterfront estates share the same problem: beautiful construction with almost no barrier against the cold.
Insulation built for Greenwich homes
Sebastian Spray Foam is a Brookfield, CT insulation contractor working in Greenwich 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 Greenwich homes. Homes around Greenwich 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 Greenwich homes are built like
Much of the housing here predates 1940, with plaster walls, balloon framing, and unfinished attics that were never designed to hold heat. Renovations routinely uncover wall cavities with no insulation in them at all.
Working in Greenwich
Backcountry Greenwich sits on large wooded lots where the homes tend to have deep attics and unconditioned crawl spaces. Those two spaces are where most of the heat loss is on properties in that part of town.

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