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