Spray Foam Insulation in Roxbury
Roxbury is a small, rural Litchfield County town of farmhouses, converted barns, and quiet country homes on generous lots. It has long drawn people who want space and privacy, and those older houses reward an envelope that is finally sealed properly.

Insulation built for Roxbury homes
Sebastian Spray Foam is a Brookfield, CT insulation contractor working in Roxbury and across Litchfield 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 Roxbury homes. Homes around Roxbury 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 Roxbury homes are built like
Roxbury's housing runs to antique farmhouses and colonials, many with fieldstone foundations, unfinished attics, and additions built across different eras, so heat escapes through a patchwork of weak points.
Working in Roxbury
On Roxbury's back roads the homes sit on open, wind-exposed land, so sealing the attic and the rim joists is what steadies the temperature against a cold night.

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