Spray Foam Insulation in New Canaan
New Canaan is known for its modernist glass houses and its grand estate colonials, a town where design matters and the building stock spans two centuries. Both extremes share a need: an envelope that performs without compromising the architecture.
Insulation built for New Canaan homes
Sebastian Spray Foam is a Brookfield, CT insulation contractor working in New Canaan 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 New Canaan homes. Homes around New Canaan 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 New Canaan homes are built like
Alongside the antique colonials near the village, New Canaan holds a remarkable collection of mid-century modern homes, many with flat roofs, large glazing, and minimal wall cavities that make careful air sealing essential.
Working in New Canaan
The heavy renovation market here means many homes are being opened up, which is the ideal moment to seal the attic, walls, and rim joists properly before the finishes go back.

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