Spray foam insulation in Queens

Spray foam for Queens homes

Queens has more detached and attached houses than any other borough, and most of them were built with little or no insulation. Spray foam fills the gaps and seals the air leaks that loose insulation leaves open, so it suits the spaces that are hardest to insulate well.

Where we spray in a Queens house

• Attics and cathedral ceilings: foam under the roof deck in Tudors, colonials and capes, when the attic is used or the ceiling slopes.
• Rim joists: the band where the floor framing sits on the foundation, a big source of drafts.
• Basements and crawl spaces: closed-cell foam on the walls, for warmer floors over them.
• Row-house roofs: in Ridgewood and Middle Village, closed-cell foam under the flat roof deck.

Open cell or closed cell?

• Closed cell: dense and water resistant, for rim joists, basements, crawl spaces and flat roofs.
• Open cell: lighter, for pitched roofs and walls, and it quiets street and airplane noise.

We tell you which fits each part of the house after we look at it.

Rebates

Queens is split between utilities. Much of the borough has National Grid gas, parts of northwest Queens have Con Edison gas, and the Rockaways have PSEG Long Island electric. Most one- to four-family homes now go through NYSERDA programs. We check what is open for your address before we price the job. See the NYC rebate guide.

Common questions

Can you foam a finished attic? Only where the roof deck can be reached. Otherwise blown-in insulation fills the closed spaces.

How long does it take? Most Queens homes take one or two days.
