These guys are excellent. Coordinated the spray foam of our shipping container and did an excellent job. They were able to do it in the dead of winter and got under the container, which is only a foot and a half off the ground. You will not find a more affordable contractor for spray foam in Vermont or Northern New Hampshire. The owner is very friendly and we'll do all the calculations to customize the estimate to your exact job.

They are a great company and did a fantastic job in our house. They helped us understand how to foam our roof, all the walls, the sill plates, and even the basement walls. Very reasonable pricing and works with efficiency VT to assist with rebates. Easy to schedule they showed up on time. They did a great job. They cleaned up before they left. Everything went as expected.

They did the outer perimeter of my log cabin. The cabin is built on concrete pillars with a 3 foot crawl space under cabin. When it was -29° degrees out under my cabin with no heat was 45°. Great job, Great crew will use them again in the future.

Jonathan came all the way up to the Burlington area to meet me and, despite spray foam not being the best solution for my current needs, gave me a ton of useful information for a solution that would best suit my current needs. He was friendly, helpful and extremely knowledgeable to boot. I wouldn't hesitate to recommend them and will be looking forward to using them on my future home!

Ingrid French★★★★★6 years ago

After negatively reviewing another foam installer, I wanted to make sure I came back and expressed how happy I was with Environmental Foam of Vermont!! They were able to fit us in last year on fairly short notice before the temps really dropped after another contractor provided us less than ideal service. They not only gave us a substantially better price but they also suggested different types of insulation that we could use in the floor before it would be sprayed to give us the best result (and also saved us money). Their employees worked late to finish the job in one day instead of coming back for a second, which we appreciated because we were not staying in the house during the foaming process. The gentleman who came to do our quote looked at areas in our home that we were not even having work done on and provided us with free advice on things we could do to seal the house better to prevent heat loss! Everyone we dealt with was nothing short of friendly and professional and I would definitely use them again for any future projects.

Jeff Robbins★★★★★6 years ago

Really pleased with the work from these guys! While other installers were non-responsive or didn't seem particularly interested in our relatively small job, Environmental Foam took the time to talk to me about options for our project that exceeded my expectations. I was amazed at how efficient and clean they were with the install. They have the process down to a science and left no trace except a very well insulated room behind them. Very reasonably priced and friendly guys to boot. Would recommend them without hesitation.

Jeremy Hudson★★★★★6 years ago

These guys are great! Was looking for the right blend of responsive, professional, and fair pricing for insulating the floor of a sunroom and didn't want some big contractor gouging me on the small job. They were able to come out within 2 weeks of reaching out and were swift & courteous, and did a nice tidy job! I'd recommend Kent and his crew in a flash.

Frequently Asked Questions — Spray Foam Insulation in Burlington

Why is spray foam insulation especially important in cold climates like Burlington?
In cold climates like Burlington, VT, proper insulation is critical to preventing heat loss, ice dams, and frozen pipes. Spray foam's air-sealing properties stop the cold air infiltration that traditional insulation cannot address. It also prevents the moisture buildup inside walls that leads to mold in cold-weather freeze-thaw cycles. Homeowners in VT typically save 25–35% on heating costs. Note: in tightly sealed homes, proper mechanical ventilation is commonly recommended to maintain fresh air exchange without losing the heat you've paid for.
Does spray foam insulation prevent ice dams in Burlington?
Yes — spray foam insulation is one of the most effective solutions for preventing ice dams in cold climates like Burlington, VT. Ice dams form when heat escapes through a poorly insulated attic, melting snow that refreezes at the eaves. By creating an air-tight thermal barrier in the attic, spray foam eliminates the heat loss that causes ice dams in the first place.
What R-value do I need for spray foam insulation in Burlington?
For cold climates like Burlington, VT, the Department of Energy recommends attic insulation of R-49 to R-60. Closed-cell spray foam provides R-6 to R-7 per inch, meaning 8–10 inches achieves code-minimum performance. Open-cell foam at R-3.5 per inch requires greater thickness. A local contractor familiar with VT building codes can recommend the exact specification for your home.
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?
Spray foam insulation typically costs $1.00–$3.00 per square foot installed, depending on the type and your location. 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 costs $2,000–$6,000. Most 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?
Look for contractors 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 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 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.
