Green Collar

Green Collar installed vapor barriers in my basement and sealed up numerous spots in addition. They also installed a turbine vent in my attic and insulated the attic thoroughly. The guys were prompt, courteous, and cleaned up very well before leaving my house. I would recommend them highly for any Mass Save work in your home. Deb Henson

We had Green Collar install blow-in insulation, weatherstripping, etc. in our home - they were fantastic! On time, responsible, courteous, informed, and the list goes on and on... The house is now capable of withstanding New England Winters... !!! Thank You Green Collar!

I could not have picked a better company then Green Collar to add insulation to my Attic and cellar. The crew was courteous, professional and very informative as to what they would be doing. Everything was clean beyond expectations before they left.if you're looking for a good insulation company do not hesitate to use these folks.

Yesterday Green Collar sent Wilson, Josh and Ricky . Great crew they worked well together. Arrived on time explained the process. They did extensive work throughout my home All 3 were very friendly and professional. My husband was there the whole time and he said they never stopped. We can all ready feel the difference. Also shout to the gal in the office very friendly and helpful. Thank you Mass save for picking a 5 star company.

Just had Green Collar add spray insulation into my attic and bring the R rating up to code. All three workers were professional and did a great job. They air sealed and installed a proper vent for the bathroom exhaust fan as well. I highly recommend using this company. Friendly and helpful staff administration as well.

The Green Collar team did amazing work at our house! We have extremely high electricity bills, and they were recommended to us as contractors through the MassSave program. They fully insulated our attic — including building custom insulated covers for the pull-down access and fan — and also installed weatherstrips on all our external doors. The crew was on time, super nice and professional, laid tarps everywhere in the house where they were working, and by the time it was over, had left the house cleaner than they found it! I really could not be happier with the quality of the work, the friendliness of the office staff and work team, and the cost. Based on that experience, I am exploring installation of a mini split unit with them. Highly recommended.

Cecile was kind and helpful. She assisted us in resolving an issue on the end of the Mass Save program with ease after a different Mass Save contractor didn't show multiple times. Green Collar was called in to do the work and came on time, did the work expected and we had no problems. They were great. I would suggest if you use the Mass Save program, that you request Green Collar does the work. 5 star.
Thank you, Courtney

The team from Green Collar were great! From the moment they provided the estimate and answered all my questions, to the last moments of cleaning up, the staff and crew were very professional, polite, and respectful of my household. The Crew Chief, Rob, kept everything moving; everyone on the team knew their jobs and did them well. They worked very efficiently under some difficult conditions and laid down cloths over my floors and kept the dust contained while they insulated my attic and basement perimeter. They delivered the work they said they would, and they left my basement cleaner when they left than it had been when they arrived. They followed up by walking me through all the work they had done. It was a pleasure to deal with Rob and this company. I would definitely recommend Green Collar!

The Green Collar team of Wilson and crew was awesome, very experienced, in this industry, good leadership and team support, very considerate and helpful. I really appreciated the job they did and am looking forward to a much warmer house. This was a Mass Save project (free for the homeowner,) so I am unsure of what the cost was but the return is invaluable.

If you are having insulation work done at your home, look no further than Green Collar. Due to the busy time of year for this work, I was scheduled for the middle of February, however Green Collar always made an effort to keep moving my install date up so I could get it done sooner. They were able to fit me in before the new year, which was such a great surprise. I'm already noticing a huge difference in our heat in the house, and we still have thr exterior walls to go. Green Collar's crew was incredibly professional,courteous, focused, and cleaned up very well when they were done. Can't go wrong with this company.
