These guys are very courteous and professional. They did a great job insulating the attic of my Victorian home and the results are VERY noticable. If you're on the fence about closed cell spray foam, don't be! It's not cheap, but it is absolutely worth it.

I contacted Mark regarding spray foaming our rim joists area of our 30 x 40’ colonial built in 1991 with closed cell foam (to replace blanket fiberglass), he responded to our request and came to look at the job within a week. We determined that I currently had R8 and not airtight, which was replaced with closed cell foam at R22 which would be airtight. His quote was very competitive to others we had spoken with. The construction of our home was a little different than normal conventional ‘2 by’ lumber, we have TJI joists (wooden I-beams). Along each TJI as it sits on the sill plate is a 2x4 on both sides. As you can see in the picture this creates a challenging area for traditional crack sealing and even fiberglass blanket insulation to do an effective job at insulating the ‘critical seal’ area. The infrared image was taken on March 20th, when it was 25°F outside. The temperature listed (57.7°) is what the crosshairs in the center of image is sensing. The blue and dark areas show significantly colder areas (gap between TJI and 2x4). The solid blue section on the bottom is the top of the concrete wall, the horizontal red line is the hot water heating pipe. I have also included an after shot when it was spray foamed. This winter when the weather gets colder I hope to be able to take another infrared image for comparison. I highly recommend Mark and his team at Foam USA. They were easy to work with, they took care to prepare the space for over spray, and willing to work with me with custom add-ons that I requested. I would not hesitate to refer or use them again.

We have been renovating a very big, very old house in the Berkshires for three years. In all that time, we have dealt with no one more professional, capable, and courteous than Mark Lantz and his team from Cozy Home and Foam USA. The house was difficult to insulate because of its age and the way it was built, but Mark took time and used his impressive knowledge to develop the best approach, down to the smallest detail. His team was clearly experienced. They worked efficiently and thoroughly, and left the house remarkably clean--considering what a mess the spray foam is in general. I would recommend Cozy Home and Foam USA to anyone.

Frequently Asked Questions — Spray Foam Insulation in Northampton

How much can spray foam insulation save on heating and cooling bills in Northampton?▼
Homeowners in mixed climates like Northampton, MA 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 Northampton?▼
For most homes in Northampton, MA, 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?▼
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.
