Green Collar

Jimmy and his crew from Green Collar sealed and insulated my attic. They were right on time, friendly, professional, and very thorough. They did a great job cleaning after they were done. Highly recommended!

Wonderful experience with Mark, Travis, and Francisco. They showed up early, worked so efficiently, and cleaned up everything after spotless. You couldn’t even tell they had been there for hours once they left. Highly recommend!

Devon and Jose weatherized my little house. They insulated my utility room. Did an amazing job insulating an exterior homemade wood door. Weather stripped my front and back deck doors. And plugged several holes from the previous owners DIY work. They were courtesy and careful of my home. Making sure not to track snow and mud into it as there was a winter storm brewing that day. They cleaned up after themselves and checked in with me frequently. I was impressed with the quality of service they provided.

Devon and José were extremely neat, competent, kind, and thorough! They did a great job adding insulation to the attic space through the Mass Save program for which I am very grateful. I was easily able to work from home while they did their work, and always felt communicated with and reassured throughout the process. I would definitely recommend their services in the future!

We were really excited about having Green Collar do an insulation assessment so we could properly insulate our house, but they rescheduled 4 times and then never showed for the final scheduled appointment. We live a little far from their base, so I understand not wanting to come out here, but I wish they would have just told us they couldn't do it rather than stringing us along.

JOB: Breton Estates Apartment Complex in Palmer MA - Blown in Attic Insulation as well as sealing up un-controlled air leakage to attic. Vent bath fans to roof and add Thermal Barriers to non-protected Hatches to attic. From the beginning, starting with the Office for set up and the workers who did the job this was 1 top notch company. Were very respectable of Tenants when they had to enter the hatchways to do the job. Communicated throughout day if there were any questions or changes. I would definitely recommend them. Call our office if you have any further questions about the job.

Noah and his crew came in and worked in my home for 2 days. They made sure that they kept me informed about everything they were doing. They kept my house spotless. Very friendly, very knowledgeable! I would highly recommend them! I can’t reiterate how friendly and nice Noah and his crew were!

Devin and Jose of crew 5 came by to complete the insulation work through Mass Save. These guys showed up on time, were tremendously friendly and took time to explain everything they were doing. I work from home and they were super respectful of my space and time. They worked with efficiency and focus and carried themselves as professionals. If I had additional work to be done, I would ask for them in a second. 10/10.

Green Collar recently did insulation work for us. Mark, Travis and Brandon were prompt, polite and took care to treat me and our home with respect. Thank you!

Green Door did a great job with their insulation services. As soon as we received the Mass Save report, I called them and got on a wait list with them. Even though they told me that I may have to wait a couple of weeks until they had an opening, they called me within a few days and in less than a week they had insulated our house. I couldn't have been happier with the work that they did. The two people who came were very friendly, hard-working and professional. They carefully explained all of the steps they would take when they came into the house and checked in with us throughout their 6-hour visit. We're now enjoying the fruits of their labor. The house is warmer and more efficient. I strongly recommend them. They're excellent.
