Spray Foam Insulation in Bronxville
Bronxville is a small, affluent village of stone and Tudor homes, anchored by the Lawrence Park historic district and its early artists' colony houses. The architecture is distinctive and often a century old, which is exactly where careful insulation pays off.

Insulation built for Bronxville homes
Sebastian Spray Foam is a Brookfield, CT insulation contractor working in Bronxville and across Westchester 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 Bronxville homes. Homes around Bronxville 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 New York season, with lower bills to match.
What Bronxville homes are built like
Bronxville's housing is dense and historic, with stucco Tudors, shingled Victorians, and stone houses built into the hillsides, most with plaster walls and attics that were never sealed for modern comfort.
Working in Bronxville
In Lawrence Park and along the village's steep streets, the older homes sit close together and lose heat through the roof and the band joists, which is where we focus first.

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