Basement and crawl space insulation in Brooklyn

Basement and crawl space insulation in Brooklyn

Cold first floors, frozen pipes and a musty smell usually start in the basement. Older Brooklyn foundations let in cold air at the rim joists, where the floor framing sits on the wall, and dampness through the masonry.

What we do

• Rim joists: closed-cell foam seals and insulates the band around the top of the foundation, the leakiest spot in most basements.
• Foundation walls: closed-cell foam on the walls keeps the basement warmer and slows the dampness coming through old stone and brick.
• Crawl spaces: foam on the crawl space walls, or under the floor above, so the rooms over it stop feeling cold.
• Basement ceilings: when the basement stays unheated, we insulate the ceiling instead, to keep heat in the rooms above.

Finishing your basement?

Have us foam the walls before the framing and drywall go up. It is far easier than coming back later.

Rebates

Most of Brooklyn has National Grid gas. National Grid’s Total Home Comfort program is paused for new applications, so most one- to four-family homes now go through NYSERDA programs, and buildings with 5 or more units through National Grid’s multifamily program. We check what is open for your address before we price the job. See the NYC rebate guide.

Common questions

Will foam stop water coming in? It slows dampness through the walls, but it does not fix leaks or flooding. Those need to be fixed first.

How long does it take? Most basements take one day.
