Mike was very responsive and informative, stopping by promptly to survey the job and complete an estimate, educating me about different types and levels of insulation he recommended in different places. I felt confident in hiring him that he and his team would do a thorough, quality installation and he did not disappoint. He was easy to work with in scheduling and in executing the job, cordially working around all my stuff to efficiently complete the job in well under a day. He left the site clean and neat and took away all waste materials, even helped me carry things that had been moved outside (to be out of the way) back into the garage. Highly recommend Mike & Ambient Insulation.
Mike did a fantastic job insulating our project. He gave a great price. Place was clean as he found when done. Thank you
The customer service at Ambient was fantastic, first and foremost. I submitted an inquiry for an estimate and had a response in 24 hours. Mike came out just a couple days later. The quote was slightly higher than the other 2 we obtained, but ultimately, we chose Ambient for the ease of communication. Mike came out on a Monday, was punctual and answered all of my questions. I received my quote on a Tuesday and the work was completed efficiently and neatly just one week later. We would definitely use them again and highly recommend their services.

We are a new construction home and Kellen was wonderful to work with taking into account the scope of our project and making wonderful cost saving suggestions. Then we met his workers that did the fantastic job of preparing the home with plastic - a job in itself the prep work. Winston & his assistant left our home - beautifully cleaned. It was impressive how our home - was treated with respect and clean at the end of every work day. We still have more for them to do ( we broke in down in projects) and I will be happy knowing how they take pride in their work. If you need insulation- this is the only company you need- if I could give 10 stars, We would have Virginia & Rick
Kellen came out the same day I called to do an estimate. I had several other estimates but after meeting Kellen I knew I wanted him to do my house. He quoted me a fair price and was able to do the work within a week. Winston and Remy were meticulous about the prep by laying plastic down and taping everything off. The thing that stands out most about their work is the evenness of the application of sprayfoam. I had an energy auditor do an inspection the day they finished spraying and he was very complimentary about the quality of the work and the consistency of the sprayfoam depth. They left my house cleaner than it was when they started. I would highly recommend contacting Precision Applications if you are considering doing sprayfoam.
I was impressed with the level of communication that Kellen provided during the whole process. He gave some excellent ideas about how to improve the energy efficiency of my home. They were able to spray foam the underneath crawlspace and took great care around several of the water pipes. The final product I would say was an excellent value! I would highly recommend them and will use them again in the future.

Luke and his crew did an excellent job insulating our 28’ x 30’ 2-story garage 12’ ceilings in garage also were sprayed! His crew was in and out in 3 days and did a top notch job.
I highly recommend Luke. He did two difficult projects on my house and did excellent work. Very professional and helpful. Very good pricing. I will definitely call him for my next project.
Luke did an awesome job with my 1950’s cape remodel in Alton NH! Very knowledgeable about the spray foam business and offers very effective solutions that perform better than just batt insulation.

Bill and team insulated our new build last year, combination of open/closed cell and rock wool. They did a great job, nice and neat, very tight home, sound damping between rooms/baths etc. Highly recommended.
These guys are incredible, got me out of a bind when a Ma. Insulator kept putting me off. Johnson SF was there in a few days! Very professional curious crew. Cleaned up as needed. Excellent work.
Great experience! Despite the busy time of year, we were able to get a quote, onsite evaluation and insulation promptly. The technician, Mason, was courteous and efficient. Thank you, Johnson Spray Foam

We had a great experience with Farnum Insulators. Everyone we dealt with was knowledgeable, prompt, and easy to work with. They explained everything clearly and even helped us with our energy rebate process at the end of the project. We would be delighted to work with Farnum again.
Farnum was very professional from start to finish. They know what they’re doing and the results are amazing. I will work with them again.
We've done two projects with Farnum. Both times we had experience. Last time I had a small spray job performed on very short notice and I am very happy.

Cristiano was an absolute pleasure to work with and his team completed the insulation of my new home very quick and the work is top notch. The care they took and cleaning far exceeded my expectations and I would not hesitate using them again.
Spray foam Insulation, and fiberglass batt.. They are true professionals, quoted it with multiple options and re-quoted it again to confirm we have captured the scope of work. Great communication, arrived on time and they did a fantastic job. They pay attention to the details and I the price was very reasonable.
Christiano and his team were great. He came out within a few days to give me a price, gave me a few options, and was happy to adjust the quote to meet my needs. Pricing was very competitive (I spoke with 4 different companies) and the crew banged out the project in a day. We used a combination of Closed Cell, Rockwool and some fiberglass in the crawlspace and garage ceiling and everything was installed cleanly. When I had a concern about a valley between rooflines a few months after the install, Christiano was quick to respond, sending a crew the next day to address the issue. Would definitely recommend AJ Pro Green for your insulation project!

The VFI crew did an amazing job from the initial analysis of our insulation needs, best bang for the buck, through the actual foam application and excellent follow up on rebate incentives. Local business that really performs!
Excellent insulation install by VFI. Their team had an unmatched attention to detail throughout the process and cleaned up the site once their work was complete.
I have used VFI in the past to insulate my garage, so when I made the decision to "tighten up" my house, VFI seemed the safe choice. With the help of Efficiency Vermont ( 5K rebate) and VSECU (interest free loan), I contracted with VFI to perform the insulation work in my crawl space and attic. I had to vacate the premises for 3+ days, and when I returned it was as if no one had been working there. The job was complete, cleanup was generally excellent and I am enjoying the results of the upgrade. I would not hesitate to recommend Efficiency Vermont, VSECU and especially Vermont Foam Insulation.

The Absolute best service, most knowledgeable in all aspects of spray foam industry including sales, service and technical support! The master mind El Presidente - George Spanos And team are second to none as the leading distributor in North America’s spray foam industry!
Only rating this business with 5 stars is an insult to be honest, their customer service is the best I have ever experienced in the industry. The owner himself returned my call after hours from his home on his first day back from vacation to make sure my needs were taken care of. Truly impeccable service, if you are shopping elsewhere it's only because you haven't used them yet. 10/10 would recommend.
Kim, Joe, Chris, and the rest of the team are very knowledgeable about this industry and very friendly. They will always go the extra mile to get you happy as a customer with GREAT PRICES and FULL SUPORT. You can never go wrong with great prices and lots of experience, top it off with a GREAT CUSTOMER SERVICE! Great job guys!

I had them come in as an additional quote/consult on my retrofit initially because instead of putting several layers of batting up into my attic again, I just wanted it spray foamed. WeatherTight Spray Foam, and Brad specifically, are extremely knowledgable in their field. Rather than just giving me the standard pitch, Brad provided a well-thought-out solution, demonstrated real expertise, and suggested a superior approach. They took quite a good amount of time to go over everything with me and sat there in my attic with me explaining everything. I'm normally very selective and cautious with who I hire. Brad is a straight shooter and great guy once you get to know him, he's not gonna make any promises he can't keep. They did a great job, more than I could ask for, and sprayed extra! They went SUPER thick on the walls, I thought he'd only go to the studs, they went well past it. They were more than punctual and everyone that came was extremely friendly. My attic is like a giant foam cooler now. 😂 It's been 90F+ outside and I can keep the windows open, it's nuts. I can't wait until this winter when I can use 1 piece of wood to heat my whole house for a day (I'm exaggerating a bit). I wasn't sure on funding/timing, and he was extremely flexible, has great communication, if you reciprocate! They are in high demand and are really are booked out. Even though other clients didn’t respond or follow through on their appointments, he stayed organized and so he was able to accommodate me earlier than expected, showing professionalism and reliability. They brought everything to the job, they brought the whole lab with all this tech and gizmos. They didn't even use my electricity! Spray foam isn't cheap and it's a pain in the ass to DIY. When his guys came, they didn't screw around, they get it done and fast and they are professional. We did the whole thing word of mouth, Brad and WTSF is a company you CAN trust. How rare is that to find in 2025. Brad was right there with his team fully suited up doing the work and making sure it got done right! Not just some sales guy that doesn't do anything! We didn't even have to make crazy contracts or lock into some sketchy randomly emailed sales agreement like this other company tried to do with me! You should ignore that other HVAC company guys 1 star review. Obviously the guy didn't even hire them, so that shouldn't even be there. I ignored an HVAC guy myself and DIY'd my AC. They're not always right.
Brad and his guys were wonderful!! They came out did the inspection, sent us a price quote and were here in days. The installation crew were super clean, very respectful and for the noise of the install (which was minimal) you would not even know they were here cleaned up after with no signs they were here other than the warmth. No smell at all. Highly recommend them! !!!
Two very enthusiastic Thumbs Up! We had a fantastic experience with Brad and his team, from start to finish. From initial phone call, through the estimating process and very timely completion of our project, Brad's communication was super responsive and professional. The Estimate was clear and concise, yet left no unanswered questions. Their work is first rate, our old attic space is completely transformed into usable living space, and they left my house cleaner than they found it. We couldn't possibly be happier, and will highly recommend Weathertight!

"Our converted 1838 church building has never been this comfortable as we go into another NH winter!!!!!!! Thanks to Bryan and his team for an outstandingly thorough and high quality job. On time, on budget, great to work with. Superior is the way to go if you need a spray foam job done in the Upper Valley."
Bryan and his team are the best. They fit me into a tight schedule, made the trip way up to Northern VT and accommodated my schedule. The work was done exactly the way we discussed at the price that was quoted. Byran went out of his way to communicate with me, and the best way to approach the job. I couldn't have asked for a better experience in the construction process. I would highly recommend the team at Superior if you are looking to seal in your home with spray foam. Mike F. Irasburg, VT
Had Superior spray foam out to spray foam interior basement walls and rim joist pockets, they did a very nice job. Took the time prepare and set up to do a very neat and clean job, no over spray at all. Very affordable and project was complete in less than a day. Would definitely use Superior spray foam again and recommend them

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 !
Great people, hard workers, great price, people who take pride in their work. If you want your home insulated the right way, pass inspections and get it done fast, then this company is for you! No excuses, no b$.

From sales through customer service and installation. USA was top notch. Customer service answered all my questions, was quick to respond to emails and phone calls. Getting a delivery date was fast. The installation crews was clean, polite and answering my questions as we moved along. They cleaned up behind themselves and everything was put back to normal. I have a mobile home, my main source of heat is a pellet stove. Before installing the foam, I was burning about 40#s in 20-24 hours. A drastically change occurred. I'm now using half the pellets I was using before. What a huge difference it's made. I'm happy to have made the decision to go with USA and their product.
Insulation blown in garage and house attics, a 4000 sq-ft foot print. Baffles were installed between each 16 inch OC joists, and recessed lighting was enclosed. Work performed flawlessly, and efficiently. Crew cleaned up any blown insulation that was inside the garage and house as well as the driveway. With R49 garage and R60 house living space is comfortable heated. Going into a 60 degree garage while 30 degrees outside is helpful when you are loading a vehicle with kids and pets. Saving on heating bills will be a big plus. Recommend this company based on sales rep prompt call back to questions, office personal accommodation to scheduling, and install team attention to details. In this day and age finding a company that’s positive in all these areas is unfortunately rare. Pricing was fair and as the saying goes, you get what you pay for.
Would rate 4.5 if given the option. Quick appointment to schedule assessment and both assessor and install crew were very pleasant and courteous. A couple of complaints I have is the number of reminder notifications that are received prior to consultation is excessive and there was a miscommunication between the assessor and our understanding of what work was going to be completed in our eaves. Our expectations of the work to be done were not completed in the matter explained during the consultation. There were 2 ways to insulate the area and the way done was not how I wanted and expected it completed. These issues caused me to not rate 5 stars but the negotiated price and the friendliness of the crew made up for some of these concerns.

Very good work. At D&D they’re all about getting everything done right, doing it neatly and speedy! Amazing work done to every house I’ve seen. Can’t wait to see how much money people are saving from the guys over here! D&D you guys are awesome!
Dennis and his team were wonderful! We had them insulate our under-insulated attic. Communication was great, excellent service, and clean up was perfection! They truly go above and beyond to get the job done. Very happy customer.
We used D&D insulation on a bonus room in our house and highly recommend them. From the walk through to do the quote, to the day of insulation, D&D was very flexible with scheduling and kept open communication the whole time. The crew that came out was very professional and did an excellent job.

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.

Josh and his crew showed up on time, we re reasonably priced and passed insulation inspection the 1st time on our laundry room renovation. We discovered plumbing leaks and black mold. Josh took the concern of insulation right off our plates in an already stressful moment. Definitely recommend 👌
The owner is a great guy.
Josh, owner of ecologic spray foam in Dunbarton NH provided a contract, took a deposit and sprayed our new garage walls with 2” (barely) of spray foam. He claimed mechanical failure and left. Asked if we could pay him an additional $2500. He was good for it. A man of his word. No worries, he would return and finish the job. He did return when we were not home. Dumped 12 large green garbage bags of debris from other jobs in front of our garage and picked up his tools. He DID NOT finish the job. Left us with a mess. Not only the garbage, but had promised to clean the over spray and the mess he made. Do not hire this person or fall for his lies. Josh, I hope you can sleep at night and in case you’re wondering, Karma is real.
