Truly a pleasure to work with Green Era Insulation. Murad was very professional and knowledgeable.. Had our attic spray foamed with closed cell foam 5.5” R40. Prices were definitely fair and I like that he is a local business owner that takes pride in his work. Murad and his crew were awesome. Thanks for doing a great job!

Green Era was excellent to work with. Timely, cleaned up amazing, and communicated clearly during the process. There was a small issue, and not only did Murat acknowledge it, he went above and beyond to correct it and made sure I was happy with the solve. Highly recommend. Will def call his crew back should we have any other spray foam needs !

We just finished our job with USA Insulation. We couldn’t be more pleased! I Made initial contact and they reached right out scheduled time to come out. The salesman Jason was great to work with. We thought the price was fair for doing a whole home insulation job. We moved forward and they got us scheduled. The guys showed up right when they said they would. The 3 guys that came out were all very nice polite and professional. They did the job and cleaned up so well you can’t even tell they were here. All and all it was a great experience dealing with USA Insulation! Would definitely recommend.

Christiono,,Dave and crew spray insulated cleaned up, and did a thorough job on my cottage at the beach. They are great guys to deal with and their pricing and efficiency are unmatched. I would highly recommend AJ Pro for your next job.

Joe, Chris and Devin just our house after finishing the foam injection process on the back of our house. It’s been a 4 year battle trying to get to the reason for out condensation issues. Hope it works. But I will say, these 3 are 3 people I would invite over for a cookout. So friendly, funny, and accommodating my watching the process. They didn’t shoo me away and I tried to stay clear. All 3 of these guys know their stuff.

Shakes To Shingles insulated our entire condo association in Gilford. They did an amazing job at a great price! It was a huge job and they kept the area super clean, tented and safe. They were great to work with. We highly recommend them!

Michael Stevens★★★★★a year ago

Thank you Rich. Amazing job! Very professional crew! Got us under target leak! Aerobarrier is amazing technology!

Elizabeth Campbell★★★★★2 years ago

This team was the best. As a professional general contractor myself, Shakes to Shingles (also known as NE Airsealing) stands out among other businesses for their great office and field staff. They were timely, extremely competent, did excellent work, and helped me to maximize my rebate from NH Saves. They conducted blower door tests and IR camera scans to reduce my airleakage by over 50% and performed high insulation installation as well. They were clean, had great communication, and proved to be knowledgeable experts in their field. I can't recommend them enough.

Staff was friendly, helpful and knowledgeable through every step of the insulation process on our new home. We appreciated their communication and responsiveness on our home renovation project.

I sadly cannot recommend working with this company at all. Although very affordable, their lack of communication between their employees is frustrating and unprofessional. Over the course of a week, I was stood up for 4 separate appointments that was made by them! I work from home, and have a flexible schedule, but this was a bigger headache than I ever wanted. I had to call the main office and speak to the manager (Jason) on two separate occasions, who was as clueless as Mike (the project manager). And when I finally was able to get them to come to my house, they showed up at 7:30am (earliest I asked for was 8am) when the household wasn't even awake yet. Don't believe my review? Luckily, I have receipts of my entire experience with Mike, the project manager.

I had Builders Installed install gutters on my new home in 2018. The overall quality hasn’t been good. They have had to come back twice to fix leaks. I’m still having issues. I would go elsewhere when looking to have gutters installed.

Frequently Asked Questions — Spray Foam Insulation in Manchester

These are the questions Manchester homeowners ask most about spray foam cost, R-value, and open- vs. closed-cell foam — with context for local pricing and roughly 25% typical energy savings. Compare the 4 verified Manchester contractors above for exact quotes.

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 Manchester, NH?▼
In Manchester, NH 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 Manchester costs $2,000–$6,000. Most Manchester 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 Manchester, NH?▼
When searching for a spray foam contractor in Manchester, NH, 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 Manchester 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 Manchester 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.
