I never thought I would feel so moved to leave a review about an insulation company but Home Comfort Practice was so wonderful to work with. Joe came out to create a plan of what we needed to do to improve insulation in our home and then took time to answer all my questions and concerns. The crew Juan, Alvaro and Gio were awesome, they took precautions to contain any mess and were great at communicating along the way, they take pride in their work and are super dedicated. I spent a lot of time comparing and deciding which company to choose and I'm very happy with my choice. Thank you guys!!
Written by my mother who recently had work done on her house: "I highly recommend HCP! The crew were knowledgeable, and professional from audit to completion of project. They answer any & all questions or concerns. They cleaned all areas worked on leaving my home pristine daily. Customer Service is OUTSTANDING, especially Lucy B. who was so informative & friendly. So impressed with this company, they not only did my insulation but replace my windows as well! Thank you so much Mr. Wyatt for helping me make my home energy - efficient!!!"
They came and did my heating system safety check, blower door test, air sealing, led lighting, duct sealing and gave me a appointment to come back and and do insulation in my house all for no cost. I’m very satisfied and pleased with the work they have done!

I had a great experience working with Frank and Paul from Good Life Energy Savers. They were professional, efficient, and very knowledgeable. The whole process was smooth, and they took the time to explain everything clearly. The quality of their work was excellent. I highly recommend them!
Good Life Energy Savers is a professional and personable bunch of people who get the job done, and done right. We had an energy assessment recently, and they did some vent and doorway sealing for us. The work was done well, and we've noticed a difference already. We have a cat and also WFH, and the guys were super respectful of our time and space. Dom & Dave are fabulous! Highly recommend.
Highest recommendation!! I had David from the company for home energy assessment. Him with another crew member did a very good job detailing out the condition as well as dealing with a lot of air leakage paths. I got a quote from them for the attic insulation update. They made it very clear that I dont have to opt for services from them and can opt for any licensed contractor to be eligible for the rebate from the state. I got quotes from other contractors which made it amply clear that their pricing is very competitive. Juan and the crew came and did the attic insulation work. Excellent work. Hugely satisfied.

USA insulation did a wonderful job on my Condo with insulated of the entire unit… Dominik Doel and his coworker worked efficiently and very professionally trained in what they had to do… Most definitely will refer to my friends here in my Complex… Thank you..
The whole team at USA Insulation of CT was great to work with. Karissa was diligent about keeping me aware of things via phone and text, Matt did a fantastic job of determining our insulation needs and walking us through the process, and Benny and his team (Dominick, Julio, Joey, and Darian) were extremely efficient in getting the job done properly. Seriously, I work from home and it was like they weren't there at all! They got to my place right on time, set things up, got to work, and cleaned up so well after they left the place nicer than they found it! Of course, along with fantastic customer service, the insulation has already begun to pay off. Our new home had only about 5 inches of insulation in the attic (yikes) and barely any insulation at all in most of the walls (double yikes!). How the previous owners managed to survive living like this is beyond me. We realized we needed to check our insulation more thoroughly after the ac was struggling to keep our second (and main) floor below 82 degrees. We're able to track and monitor when our ac cycles on and off. Since installing the insulation just yesterday, there's already been a noticeable dip in the amount of times the ac has had to cycle on. Even now, it's 90 degrees outside while inside it's a comfortable 72 degrees. And the last time my ac had to cycle on to keep it there was... an hour ago for about 15 minutes. That is a MASSIVE improvement. So to USA Insulation of CT, you have our sincerest thanks for making our first house feel like that much more of a properly comfy (and cool) home!
Workers arrived at scheduled time and did an outstanding job. Answered any questions and concerns before starting. They proceeded to perform their work and finished efficiently. Did some extra clean up when finished and gave a thorough walk-through to explain their work. Everything was done to great satisfaction

I just worked with Dr Energy Saver to get insulation installed in my house. I would absolutely recommend them to any friends or family. From the beginning of the process through the final inspection, this company was a pleasure to work with. I would like to especially thank Keith Saunders and Johnny Lopez. Keith was beyond helpful while simply conduction the inspection and developing a quote. He really helped get me a service that was within my budget. Come installation day, Johnny was incredibly respectful and a pleasure to work with. Johnny ensured that everything was done right and the house was spotless after. Again I will absolutely be recommending this company to my friends and family.
I called Dr. Energy Saver because I had extensive mold in my attic. They did a fantastic job removing the mold, sealing air leaks and Re-insulating the attic.The upstairs is so much warmer now. They also did a great job insulating our rim joist in the basement, replaced the basement door and insulated a downstairs room. The crew was friendly, on time and cleaned up their area every day.
In Dec. 2019, I had extensive work done on my attic - air sealing, installing new insulation, a new catwalk, an insulation box over my attic ladder, improving the duct work from my bathroom fans. They did an excellent job and were pleasant to deal with. They responded promptly to my concerns subsequent to finishing the job. My only reservation was their price - $10,000 which I thought was high. but I proceeded anyway because I had confidence that they would do the job right.

Had ecologic come out to do the spray foam work in my attic and basement that we decided to finish. They were amazing and the quality of their work was very impressive. I had a different company do work two years ago on a different area in my house, and was not happy with the final product. Was unsure if I wanted to use foam again, but Rich assured me that I was in good hands with his team. The Crew that came out was very thorough and meticulous. not only was the workmanship excellent, but they left the place Spotless upon completion. I cant recommend these guys Enough!!! Thanks Guys!!
I contacted Ecologic Energy Solutions to have my old attic insulated. Sales rep Richard came out the very next day to give me an estimate which was better than I had anticipated. He was very knowledgeable about updating and suggested I foam the attic roof AND walls. I had gotten other prices from other companies but they were $500-1000 more for the same job. Even better, Richard saw the project out from beginning to end, and the crew that came did an amazing job and left my attic spotless. What more can I say? As I continue to update my house, I will definitely use Ecologic in the future for my insulation needs.
I used Ecologic for spray foam in my addition in this past fall. Of the three companies I contacted, they were the most responsive, knowledgeable and also competitively priced. Their workers were efficient, neat and it was clear they took pride in their work. I'd recommend them to anybody looking for a good insulator, really top notch.
