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!
I highly recommend Good Life Energy Savers! They did an energy assessment and recommended attic and wall insulation. After getting other quotes we eventually decided to go with them. David and his team were very helpful and responsive, answering emails after business hours and sending updated quotes to me when the scope of the work changed and the state rebate program increased. They were low pressure and attentive throughout the whole process. Frank and his team did the work over the course of 3 days. They were polite and professional and I’m very pleased with the quality of the work. They also took the time to explain things to me and answer any questions that I had. When I noticed there was some very small damage to the sheetrock, the company was quick to respond and Frank came out and repaired the wall himself, even purchasing the proper paint for it. I couldn’t be happier with the whole process and my home is noticeably warmer!
I would highly recommend Good Life Energy Savers! For the quote, Jeff was on time and walked through the proposal, process, and offered a few other helpful ideas to keep the garage warmer. Frank and Paul were on time as well, and helpful, efficient, and knowledgeable. They were courteous to make sure that they minimized any sheet rock dust or cellulose, and did a great job cleaning up. Look no further if you are doing your research on alternative companies, just go with Good Life Energy Savers!

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

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.
