We started Spray Foam Long Island with one goal in mind:
To bring the highest quality spray foam insulation to homes and businesses across Nassau and Suffolk Counties.
With years of hands-on experience and a passion for helping people create more efficient spaces, we’ve grown into a trusted name in the insulation industry. We’ve worked on hundreds of residential and commercial properties, from cozy attics in Huntington to sprawling warehouses in Ronkonkoma.
What sets us apart isn’t just our skill, it’s our commitment to doing the job right, the first time. No shortcuts. No surprises. Just expert insulation and honest service.
We specialize in spray polyurethane foam (SPF), the most advanced insulation technology on the market today. Whether you’re planning a renovation, building new, or trying to solve cold floors or high energy bills, we offer solutions built around your needs.
We know you have options when it comes to insulation contractors. Here’s why Long Island homeowners, business owners, and builders trust us:
We understand Long Island’s unique climate, building codes, and property styles. From historic homes in Northport to large commercial buildings in Hauppauge, we’ve insulated them all.
Our trained technicians follow strict safety protocols, proper installation techniques, and manufacturer guidelines. We stay current on the latest materials, building codes, and best practices.
From your first consultation to final walkthrough, we communicate clearly. We’ll answer your questions, explain your options, and provide a detailed quote, no surprises.
We use only premium, third-party-tested spray foam materials with ICC-ES approvals, Class 1 fire ratings, and high R-values. This ensures safety, durability, and performance.
Our reputation is built on results, and happy clients. We’ve helped hundreds of customers enjoy warmer winters, cooler summers, and lower utility bills.
Many homes and buildings in Long Island were built before modern energy standards. That means they’re leaking money and comfort through poorly insulated walls, ceilings, and crawl spaces.
unlike fiberglass, spray foam expands to fill cracks and gaps
often cuts HVAC costs by 20–40%

reduces noise from adjacent rooms or outside
spray foam doesn’t settle or sag over time
Whether you choose open-cell or closed-cell foam, we’ll guide you through the best option for your space and goals.
Our mission is simple:
To deliver energy-efficient, code-compliant spray foam insulation solutions that make homes and businesses across Long Island healthier, more comfortable, and more affordable to operate.
