Contacted them to spray foam our basement. Kim who scheduled our consultation and spray foam was great to work with. They got back to us quickly on the quote after the consultation and worked with our timeline before the contractor put walls up. There was a little mixup and the owner made sure we were happy. Can’t say enough about them. Will def reach out once we are ready for other parts of the house.

⭐️⭐️⭐️⭐️⭐️ I don’t usually write reviews, but this one I had to. This foam insulation guy is the real deal — professional, honest, and on point from start to finish. No games, no surprises, just solid work and fair pricing. You can tell he actually cares about the job and about doing it right, not just getting it done. It’s rare to find someone in this business who’s straight up and delivers exactly what they promise — and even more rare when their pricing is this good. Highly recommend him to anyone who wants quality without the headache.

Martine Channon★★★★★3 years ago

Outstanding. These guys are the best. Amos was incredibly knowledgable & professional—put us at ease—and helped us seamlessly navigate the National Grid Energy Efficiency Rebate Program. The work was fast, efficient, clean and done with great care in a century-old house that really needed insulation in the attic. Can't wait to see the energy cost impact and more effective/efficient heating & cooling, especially in the Summer & Winter. The insulation itself is incredibly dense, clean, practically odorless and meticulously put into every crevice. Couldn't be more pleased!

5 stars! These guys did an amazing job insulating my house in Airmont! They used open-cell insulation on the upper floor and attic, and closed-cell in the basement. They even made sure to insulate all the overhangs, so my house is fully sealed. 2 years later, my house is super comfortable, my heating system barely runs, and my energy bills are way down. Great service, and I'm super happy with the installation.

Sadkov★★★★★a month ago

The company does above and beyond. From start to finish. The team arrived on time, explained the process clearly, and worked meticulously to seal every gap and nook. They were respectful of my home, laying down protection and leaving the place spotless afterward. The owner even followed up to ensure I was satisfied. #1 highly recommended will definitely do business again.

Frequently Asked Questions — Spray Foam Insulation in Oceanside

These are the questions Oceanside homeowners ask most about spray foam cost, R-value, and open- vs. closed-cell foam — with context for local pricing and roughly 35% typical energy savings. Compare the 6 verified Oceanside contractors above for exact quotes.

How much can spray foam insulation save on heating and cooling bills in Oceanside?▼
Homeowners in mixed climates like Oceanside, NY typically see 20–30% reductions in total energy costs after spray foam installation. The savings come from both reduced heating in winter and reduced cooling in summer. The exact savings depend on your home's current insulation, size, and local energy rates, but most homeowners recoup the investment within 3–6 years.
Is spray foam better than fiberglass insulation for homes in Oceanside?▼
For most homes in Oceanside, NY, spray foam outperforms fiberglass significantly. Fiberglass batts insulate but do not air seal — meaning conditioned air still escapes through gaps. Spray foam both insulates and creates an airtight seal, addressing the root cause of energy loss. While spray foam costs more upfront, the performance difference in mixed climates makes it the better long-term investment for most homeowners.
Is spray foam insulation worth the cost?▼
For most homeowners, yes. Spray foam creates an air-tight seal that traditional insulation cannot match, reducing energy bills by 15–35% annually. It also adds structural rigidity, acts as a moisture and vapor barrier, reduces outside noise, and can increase home resale value. The higher upfront cost compared to fiberglass is typically recovered within 3–7 years. One important note: because spray foam creates a very tight building envelope, proper mechanical ventilation is important to maintain healthy indoor air quality and prevent interior moisture buildup. This is typically handled by an Energy Recovery Ventilator (ERV) — a system that brings fresh outside air in while pushing stale air out, recovering the energy from the outgoing air so you don't waste what you paid to heat or cool — or a Heat Recovery Ventilator (HRV), which works similarly but is optimized for cold climates. A qualified contractor will assess whether your home needs ventilation upgrades as part of the installation.
How much does spray foam insulation cost in Oceanside, NY?▼
In Oceanside, NY and the surrounding area, spray foam insulation typically costs $1.00–$3.00 per square foot installed, depending on the type and your home's specifics. Open-cell foam runs $0.44–$0.65 per board foot, while closed-cell foam costs $1.00–$2.00 per board foot. A typical 2,000 sq ft home attic in Oceanside costs $2,000–$6,000. Most Oceanside homeowners recoup this investment within 3–7 years through energy savings of 15–35% annually.
What is the difference between open-cell and closed-cell spray foam?▼
Open-cell spray foam is softer, less dense, and less expensive. It expands significantly and is ideal for interior walls, attics, and soundproofing. Closed-cell spray foam is denser, stronger, and provides a moisture barrier — making it better for exterior applications, crawl spaces, and areas prone to flooding or humidity. Closed-cell also has a higher R-value per inch (R-6 to R-7 vs R-3.5 to R-4 for open-cell). One key difference: open-cell foam allows some vapor movement, while closed-cell acts as a vapor barrier — an important consideration for your home's ventilation needs.
How long does spray foam insulation last?▼
Spray foam insulation is one of the most durable insulation options available, with a lifespan of 80+ years when properly installed. Unlike fiberglass batting which can sag and settle over time, spray foam maintains its shape and insulating properties indefinitely. It will typically outlast the building it is installed in.
How do I find a qualified spray foam insulation contractor in Oceanside, NY?▼
When searching for a spray foam contractor in Oceanside, NY, look for ones who are licensed, insured, and have verifiable reviews. Spray foam requires specialized equipment and training — improper installation can cause off-gassing, adhesion failure, or fire hazards. Ask for references, verify their insurance, and get at least 2–3 quotes. A qualified Oceanside contractor will also assess your home's ventilation needs — a tightly sealed spray foam installation requires adequate mechanical ventilation to prevent moisture and indoor air quality issues. FoamMatch pre-screens all listed contractors in Oceanside for licensing and insurance so you can compare verified professionals in your area.
How long does spray foam installation take?▼
Most residential spray foam jobs take 1–2 days depending on the size of the area. A standard attic takes 4–8 hours. After spraying, the foam cures within 24 hours, though most contractors recommend waiting 24–72 hours before occupying the space due to off-gassing during the curing process.
Does spray foam insulation need to be replaced?▼
No — spray foam insulation does not need to be replaced under normal circumstances. Unlike fiberglass insulation which degrades over time, spray foam maintains its R-value and air sealing properties for the life of the building. The only reasons to remove or replace spray foam are water damage, renovation work, or improper original installation.
