Devin and his crew were amazing. Super professional, considerate of the state of my house while coming in and out during a pretty crazy storm. Explained everything and walked me through every step. Cleaned everything up and did a great job patching and lining up door sweeps etc. so that everything looked good in the final state. 10 out of 5 if I could rate them that high!

The crew from Green Collar just finished an insulation and air sealing job on our house and all I can say is... Wow! Every member of the crew on a 2-day project (Leon, Nick, Jack, and especially crew lead Brian) was outstanding. Brian explained everything up front, and even found additional opportunities to increase insulation effectiveness beyond the original project scope from the Mass Save energy audit. The whole crew paid attention to detail and did an outstanding job in every aspect of the project. Rarely have I seen such a well coordinated, professional, and personable group of people from any type of home services contractor. I HIGHLY RECOMMEND Green Collar!

Green Collar will always be highly recommended by us! They just installed insulation in our Attic and Basement. The installation was stalled (our fault) the first day of a two day job and they came back the following day and worked so hard (and so long!) to complete the job in one day. Juan and his team were outstanding! Polite, considerate, accommodating to all of my questions and considerate of our goofy dog. Left our Home neat and clean. We'll use Green Collar again and will ask for the same crew.

Today I had green collar come in and install a mini split in my house. The two gentleman that did the installation Todd and Brent were amazing. Fast friendly knowledgeable and caring. Would highly recommend them to do work for anyone. They cleaned up as they worked. Never left a mess anywhere. And all the work done was done outside in the rain and not a complaint from them. Just smiles and courtesy from them. Thank you gentlemen I appreciate a job well done

I like to thank everyone at Green Collar for our newly installed heat-pumps. The process was long but helped us on every step of the way from sealing and weatherization, electrical work, and finally installation which Todd and Brent did an amazing job. Every crew member that came in to our house were super friendly and knowledgeable. I also like to thank the unspoken heroes at the office, and our sales person Sam, they were always very responsive with both emails and phone calls. Without any hesitation I will use them for future projects for sure.

Juan and his crew/Truck #3 just completed a day's worth of work on our house, which included insulating the attic and cellar as well installing new weather stripping on the front door. The entire crew was both efficient and cordial. I would happily have them back and can't recommend them highly enough.

We were assigned Green Collar through the Mass Save program. Brandon and his crew were very professional, respectful, did a great job airsealing and adding insulation to our attic, and left the work area spotless when they left. Would recommend if you need insulation work done.

Huge thank you to Brandon and his crew! Brandon and Shawn arrived at my home yesterday around 8:30 and over the course of the day I think 6 more techs showed up as this was a massive undertaking. They worked diligently, professionally, and were all very respectful of my home. They left at around 8pm having never taken a break. The work was superior quality and Brandon explained and showed me throughout the day what was going on. I cannot thank them enough for all of the energy improvements they did to my home and would highly recommend them to anyone.

Excellent experience from beginning to end. Office staff was polite and helpful and Devin and his crew were fantastic. They really took the time to deal with my quirky old house, sealing up spaces I didn’t even know existed, getting into every nook and cranny. They explained everything they did and worked with me to make sure I could still get access to what I needed access to. They were prompt, professional and courteous and I can already feel the difference in heat retention. Highly recommended.

Devon and his crew were wonderful. They showed up when they said they would, kept me informed every step of the way and did a fabulous job. They are great team, very friendly and personable. They were very careful to clean up after themselves as well. They even went out of their way to get approval for needed work that was missed when the initial estimate was done. Highly recommend Green Collar.

Choosing Green Collar to perform energy efficiency work in my home was the right decision. Garrett was knowledgeable with his inspection and estimate, Cecile was wonderful in scheduling the appointment. Brandon and his crew were prompt, respectful, neat and hardworking. My wife and I appreciated their efforts and recommend Green Collar to anyone looking for a company to improve their homes' energy efficiency.

Last week I had Green Collar come in and upgrade the insulation in my home. Since I bought the home, I experienced drafts in certain sections of the home. In some cases in extreme cold weather, the pipes would freeze in one bathroom where the cold air drafts were coming through. The home is a prefab structure which presented some challenges to the team, but they (in discussion with their office) made changes to the original plan and did a remarkable job. They also did a good job cleaning up afterwards. The result of their work is my home is better insulated, warmer and I expect my fuel oil bills to be reduced.

Brandan and his team left the place cleaner than they found it. They vacuumed all the spaces they worked in. The team was very friendly and professional. These guys saved us money and improved our insulation!

Our experience with Green Collar was wonderful. My crew consisted of Brandon as lead, Daniel, Juan, and Isaiah. They arrived on time with a professional greeting and inviting smiles. Brandon carefully outlined everything the men were going to accomplished and asked if we had any questions. After answering several, extremely well, he set the crew in motion. Following carefully thought out protocols out came the drop clothes, plastics and other protective measure to insure that our personal belongings were well protected. We really appreciated this. After a little while we invited them for coffee and snacks of which they were really appreciative. We couldn't count how many times they thanked us. They went about their business with the upmost respect for your company, in my opinion, and our belongings. They were quiet and always busy accomplishing their respective tasks. Several times they needed to ask a question and I was so delighted to actually hear someone say, "Excuse me" wait for my response, then proceed. It was so refreshing to meet such gentlemen. The work they did was neat and orderly. They cleaned up and frankly, other than being warmer we would never ever known that they were here. I have actually already recommended your company to friends and commend you for hiring such nice people. A big shout out to Daniel, Brandon, Juan, and Isaiah along with the office gal whom was warm and friendly each time we chatted. Many thanks for a job well done.

Brandon and his crew, Brian and Andre, were fantastic - capable and careful, they did the job efficiently and even went above and beyond, fixing a duct connection we didn't know was loose. Also nice guys! Highly recommended.

Todd, Brent and John were all awesome. Super professional experience. Everyone was polite and very transparent about the process. They cleaned well each day and clearly overcame a number of challenging obstacles to get the job done right. Due to some of the intense obstacles, the project ended up lasting an additional day and instead of delaying us, they came back on a Saturday and finished the job. These folks are great and we highly recommend them.

Relocating to the Western Massachusetts area has posed some challenges in finding reliable, professional, and knowledgeable tradesmen.However, I am pleased to share my positive experience with Green Collar Insulation Contractor, located in South Hadley, Massachusetts.Throughout the whole process, I was impressed with the level of service provided by their team.Garret, who was my initial contact, was both friendly and professional. He demonstrated a deep understanding of their product line and was able to offer valuable insights on how to achieve maximum efficiency for my home, whether it was for insulation or mini-split solutions.Wes, the head foreman, was responsible for overseeing the installation process. He did an excellent job of keeping me informed and ensuring that everything was well-organized.I'd also like to commend the exceptional work of TODD and BRENT, two installers who went above and beyond in terms of professional and customer service. Their expertise was evident as they flawlessly installed the mini split units, leaving no unsightly wires in sight. Not only did they arrive punctually, but they also left my home as clean as they found it. I am incredibly grateful for their impressive work.Furthermore, I'd like to acknowledge the outstanding performance of the SWEC Electrical Contracting Services, technicians John, Scott, and Won. Their professionalism, knowledge, and friendly demeanor were evident throughout the complicated installation process. They, too, did a remarkable job.I am extremely grateful and deeply appreciative of all those individuals who provided me with assistance throughout this installation process.Overall, Green Collar Insulation Contractors proved to be the ideal choice from start to finish. I am delighted with my mini splits and can confidently say that I am a very satisfied customer!!!

Green Collar did some basement insulation work for my mother recently and did a great job. They were very friendly and patient, and it was a crawl space-style basement so it was hard work. Kudos to Francisco, Bryan, Juwan, and Isaiah for a job well done. My mom says “10 stars!”

We had Green Collar come out and service our mini split. Brent and John were the guys that showed up and they did a great job! They were thorough throughout the process.

Had sealing and insulation done recently in our 1960s ranch. The two guys that came out did an excellent job and talked us through everything they were doing and why. Very friendly, and an overall educational experience. We had one minor issue with a bathroom fan after they left, but Green Collar had someone out the next day to take care of it. Would hire them again.

We had a fantastic experience with Green Collar from start to finish. Sam was super quick to provide us with an estimate and Brandon and his crew arrived on a weekend to help us beat the frost with needed insulation. Green Collar was professional, thorough, and responsive from start to finish. Thank you so much!

Green Collar is the best! Todd and Brent did the installation of two splitters on our two family recently and the professionalism and workmanship that they provided was beyond comparison! The work was neat and placed appropriately and completed in a timely manner. They took the time to explain all of the operation details as well as the maintenance required. They left the place spotless also.. another plus and they were super courteous during the installation. In this modern day where good customer service is hard to find, these gentlemen are a breath of fresh air and a credit to their company. Because of my experience with them, I will be recommending Green Collar services to my colleagues and friends in the future.A satisfied customer in Erving, MAA.B.Service: Fan installation

Really happy with the work done by Green Collar - Brandon and his crew (Georgie, Nick). They showed up promptly, went right to work. They first made sure that all the walkways to the work areas were protected, which I really appreciated. They were thorough, air sealing the basement and attic spaces and insulating the attic . Great attitude by everyone, and they also left things spotless after they were done. I checked out the company before I contracted with them, and all the good reviews are true. I would not hesitate to use them again for future work.

Brandon and his crew were incredibly hard working and left my house clean. Brandon touched base with me about any change in the work as well. My house already feels less drafty and cozy. Thanks again for all the hours put in to do the work and finish the job.

Brian (I think that was his name) and his crew did an outstanding job insulating my attic; they were all upbeat and pleasant the entire time they were onsite. The work was not fun, but they all had smiles and great attitudes, going the extra mile for minor details most people would have overlooked. I am excited to hire them to do a set of mini-splits soon.

I have had energy audits at three homes with various crews and Brandon and his crew were by FAR the absolute best! There are not enough superlatives to describe them. They exceeded my expectations, performing: sealing, insulating, foaming, (even adding steel wool to help with my mouse problem), and cleaning up before leaving. They were professional, thorough, polite, and friendly. In a word they did a FABULOUS job!!!!
