Reviews
Write a ReviewJeremiah and his crew did a fantastic job. They arrived on time, worked very hard in the small hot attic space, did not waste time and were very professional. Jeremiah explained from start to finish what the job entailed. When the job was completed, Jeremiah explained all that was done and wanted to make sure we were completely satisfied before leaving. They also cleaned up and did not leave a mess. We are very pleased with Green Collar and Jeremiah and his crew!
I normally donâ  t write reviews, but I Felt the need to about this company, and it employees from start to finish I have never been so impressed ! We had replacement windows installed today everything was measured perfectly and all the windows were installed y Robert. What an amazing company and employee! Thank you Green Collar!
The work crew of Alex, Devon, and Brandon were awesome. I was impressed how well they knew their craft. All were professional and demonstrated a maturity beyond their years in finishing this challenging project. In addition, they were very conscious of our needs, as we tried to keep our three year old grandchild out of their hair! Great guys. We highly recommend them!
Fabulous job! We area already see the difference with the insulation through Mass Save about 25%! Mark and his crew were very professional, courteous, and really nice guys. Garrett did a great job with estimating and made the process very easy and recommended additional measures to explore. I highly recommended Green Collar!

I am scheduled for service on January 25 and 26, 2023. Ask me in February.
Hi William. Looks like your project was completed back in January. Is there anything we did during the process, or can do now, to improve on your initial one star ratings that were based on your not having worked with us yet?
Great experience from start to finish. Gave good advice, scheduled and completed the work promptly, and we love our new mini-split. The customer service is great and they have quickly helped us with our follow-up questions and paperwork for our rebate. To top it off, their prices are really reasonable!
Great service! Made excellent recommendations and ultimately saved me a bundle! Highly recommend.
The crew with Mark in the lead showed up on time and went right to work. Mark explained all the work being done. I'm very pleased with the quality of the work and materials. Thank You Mark and your Green Collar crew.
