Spray Foam Insulation in Southbury
We insulate Southbury homes and additions so every room holds its temperature through Connecticut winters.
Insulation built for Southbury homes
Sebastian Spray Foam is a Brookfield, CT insulation contractor working in Southbury and across New Haven 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 Southbury homes, and commercial insulation for the buildings along its business corridors. Homes around Southbury 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 Southbury homes are built like
Southbury ranges from the historic homes around Southbury Green to the mid-century neighborhoods along Main Street South and Route 6 and the condominiums of Heritage Village. The older houses leak through attics and foundations; condominium and addition work is mostly air sealing and insulating to the existing structure.
Working in Southbury
Southbury sits where New Haven County meets Litchfield County, between Newtown and Woodbury. Additions and finished basements are common here, and both start with sealing the rim joist and the attic.

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