Jeremiah 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!

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!

"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!

I just hired them this week, so they haven’t started yet. They are doing it the way “This Old House,” does it (knee wall) and the price is very fair considering another estimate, wasn’t adding any foam board over the batts. I chose 5 star reviews and “up to code,” insulation pro.

The two gentlemen were conscience of CORVID and wore masks. They NEVER STOPPED. They just keep going and working together in unison. Two days of working like they were on fire. Worked fast and did it to perfection. We were so amazed when the job was completed. The young men were named: Matthew Berman and Izzy Lopez and you see that they wanted all to be perfect. Green Collar is fortunate to have these two men as they worked like it was their company wanting noting less than perfection. We highly recommend Green Collar. Ken & Patty R
