Spray Foam Insulation in Carmel

Carmel is Putnam County's seat, a lake town centered on Lake Gleneida, and its hamlet of Mahopac wraps around Lake Mahopac to the west. Between the two lakes and the reservoirs around them, a lot of Carmel's houses live close to the water.

Insulation built for Carmel homes

Sebastian Spray Foam is a Brookfield, CT insulation contractor working in Carmel and across Putnam 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 Carmel homes. Homes around Carmel 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 Carmel homes are built like

Carmel and Mahopac have lake homes and former summer cottages along Lake Mahopac, Lake Gleneida and the smaller lakes, older village houses near the county buildings, and capes, raised ranches and colonials built from the 1950s on as the area filled in. The lake houses deal with damp crawl spaces and wind off the water; the mid-century homes have thin attic insulation and open rim joists.

Working in Carmel

Coming from Brookfield it's I-84 to Route 6, around 35 minutes. Lakefront and hillside homes get different work: closed-cell foam where the ground is damp, attic air sealing and insulation up on the hills.

Questions from Carmel homeowners

Do you work in Carmel?

Yes. Sebastian Spray Foam is based on Federal Road in Brookfield, CT and works across Putnam County, including Carmel and nearby Brewster, Patterson and Somers. Call (203) 546-7800 or request an estimate and we will set up an in-home assessment.

Why are the floors in Carmel 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 Carmel?

First, an in-home assessment: we inspect your attic, walls or crawl space and find where the house is leaking energy. In Carmel 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 Brewster, Patterson and Somers. Then the install: our own crew seals the envelope, protects your home throughout, and leaves it spotless, anywhere in Putnam County.
