Building Envelope Solutions
Who we are
Insulation Builders is a Brooklyn insulation contractor. Our shop is at 3701 Bedford Avenue, and our crew works across New York City and Long Island. We do one thing and do it well: the building envelope, meaning the insulation and air sealing that keep heat in during winter and out during summer.
We work on every kind of building in the city: brownstones and row houses, one- to four-family homes, apartment buildings, offices, warehouses and industrial space.
What we do
- Spray foam insulation, open and closed cell
- Blown-in insulation, cellulose and fiberglass
- Air sealing
- Rockwool soundproofing
- Crawl space and wall insulation
We also offer K-13 acoustic spray and intumescent fireproofing paint for projects that need them.
How we work
We tell you what we’d do in our own house. We look at the space, explain the options in plain words, and give you a written price.
We handle the rebate paperwork. Utility and NYSERDA programs change every year. We check what’s open for your address, and if your project qualifies, we file it. Read our NYC rebate guide.
We clean up. We protect floors and furniture, and leave the work area clean.
We stand behind the work. If something isn’t right, call us and we’ll come back.

Common questions
Are you licensed and insured? Yes, and we send certificates when a building or board asks for them.
What kinds of insulation do you install? Spray foam, blown-in cellulose and fiberglass, mineral wool and rigid board, plus air sealing.
How do utility rebates work? Most programs need an approved application before work starts. We check eligibility, submit the paperwork, and install once the program approves it.
What does it cost? It depends on the area, material and access. Our instant estimate gives a range, and the site visit gives you a firm price.
