Brian was informative, responsive, and easy to work with. Quality work and reliable service! I’d absolutely recommend them and will be our “ go to “ for future projects.

Brian Lynch and his crew are amazing and efficient. I particularly appreciate his knowledge of insulation materials, Connecticut micro-loans, and tax benefits. His expertise helps us insulate cost-effectively. The crews are on time, answer all questions, and clean up well after the job is finished. I would choose Koala Insulation of Southern Connecticut again. I highly recommend.

The New England Performance Insulation (NEPI) was prompt well mannered and friendly. When they were done they cleaned up and left the jobsite cleaner than it was before they started. The whole experience with NEPI very good and I would recommend if you need insulation work that you include them in the list of contractors to get quotes from.

J Raymond★★★★★a year ago

After getting several estimates I chose NE Performance Insulation for my project because of their pricing, understanding the scope of the job, and I support Veteran-owned businesses. Thank you for your service! Carol handled the scheduling, and was able to move my job up by 2 weeks, it all worked out great. Communication was excellent, always a quick response. The guys came and finished the job in one day. No problems. The next day I told Carol everything looked good, but there were some areas that needed to be cleaned up, etc., thinking I’d just have to do it myself. She got right back to me and set up a time for them to come back. THAT’S why you should use these guys!

Yesterday, New England Performance removed 20+year old fiber insulation and replaced it with new insulation along the entire length of my undercrawl space, and sprayed exterior foam under the shingles. The job was long overdue. Three very nice young men cleaned out my crawl space, completed the job by mid-afternoon and the BRS dumpster was gone by 3pm. Highly recommend New England Performance for your insulation needs.

USA insulation did a wonderful job on my Condo with insulated of the entire unit… Dominik Doel and his coworker worked efficiently and very professionally trained in what they had to do… Most definitely will refer to my friends here in my Complex… Thank you..

The whole team at USA Insulation of CT was great to work with. Karissa was diligent about keeping me aware of things via phone and text, Matt did a fantastic job of determining our insulation needs and walking us through the process, and Benny and his team (Dominick, Julio, Joey, and Darian) were extremely efficient in getting the job done properly. Seriously, I work from home and it was like they weren't there at all! They got to my place right on time, set things up, got to work, and cleaned up so well after they left the place nicer than they found it! Of course, along with fantastic customer service, the insulation has already begun to pay off. Our new home had only about 5 inches of insulation in the attic (yikes) and barely any insulation at all in most of the walls (double yikes!). How the previous owners managed to survive living like this is beyond me. We realized we needed to check our insulation more thoroughly after the ac was struggling to keep our second (and main) floor below 82 degrees. We're able to track and monitor when our ac cycles on and off. Since installing the insulation just yesterday, there's already been a noticeable dip in the amount of times the ac has had to cycle on. Even now, it's 90 degrees outside while inside it's a comfortable 72 degrees. And the last time my ac had to cycle on to keep it there was... an hour ago for about 15 minutes. That is a MASSIVE improvement. So to USA Insulation of CT, you have our sincerest thanks for making our first house feel like that much more of a properly comfy (and cool) home!

Frequently Asked Questions — Spray Foam Insulation in West Haven

These are the questions West Haven 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 7 verified West Haven contractors above for exact quotes.

How much can spray foam insulation save on heating and cooling bills in West Haven?▼
Homeowners in mixed climates like West Haven, CT 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 West Haven?▼
For most homes in West Haven, CT, 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 West Haven, CT?▼
In West Haven, CT 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 West Haven costs $2,000–$6,000. Most West Haven 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 West Haven, CT?▼
When searching for a spray foam contractor in West Haven, CT, 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 West Haven 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 West Haven 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.
