Long Island Insulation Contractor

Insulation for Long Island homes and buildings

We cover Nassau and Suffolk, from the towns closest to the city out through the North and South Shores. Long Island homes tend to be larger, with full attics and basements, so attic air sealing and insulation is usually where the savings are.

What we do on Long Island

• Spray foam insulation: attics, cathedral ceilings, rim joists, basements and pole barns.
• Blown-in insulation: attic floors and closed walls in older homes.
• Air sealing: the leaks that cause drafts and ice dams.
• Crawl space insulation: for cold floors and damp crawl spaces.

Long Island homes we know

Capes and colonials. Knee walls, short attics and finished upstairs rooms are often under-insulated. We seal and insulate each space.

Ranches and high ranches. Long, open attics are well suited to air sealing plus blown-in on the attic floor.

Shore homes. On the South Shore, we use closed-cell foam where moisture and wind are a concern.

Areas we serve

Nassau County, including Great Neck, Manhasset, Hempstead, Garden City, Mineola, Freeport, Long Beach and Massapequa. Suffolk County, including Huntington, Babylon, Islip, Smithtown and Brookhaven.

Rebates for Long Island homes

On Long Island, gas is mostly National Grid and electric is PSEG Long Island. That can open National Grid programs, PSEG Long Island programs and NYSERDA programs, depending on your home and what’s funded this year. We check what’s open for your address first. Read the NYC and Long Island rebate guide.
