"Amazing company, work was done perfectly. They waited for a few rainstorms to make sure roof didn’t leak before payment. I will use them when I’m ready to replace the whole roof. Honest and reliable."

"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 hired a different business outside of HomeAdvisor"

"Extremely happy with Cory and his crew. He was great with communication, great pricing, and delivered a fantastic product. We are extremely happy with how our home came out. The siding and metal trim work look amazing! I will use Cory for any future projects and recommend him to everyone who asks about siding work. 10/10!"

"Great job on basement insulation."

"We had American Hime Fitters put in a couple doors and windows. We called about a month ago, they were very prompt and professional showing up on time. Our materials as well as the install happened quicker than we expected right before Christmas. If you are looking to get projects done this is the Go to Company. Jay and Shawn were a great pleasure to work with and they made our dreams and expectations happen."

"I didn’t just get 1 person, I got 3 working on my projects since he came with his 2 brothers which made the project go much faster. I had an idea about what I wanted but he helped design the deck and added beautiful details to make it look better then I had imagined! They worked straight through the heatwave we unfortunately were hit with right on the dates my deck construction was scheduled for, and though I would have understood if they had said they needed to push back the project until the heat wave broke, they just came earlier in the morning each day to be able to still complete the work within the time I had been told! Very impressive. They also stayed true to the price they originally quoted me even though once getting into to project realized that it was going to take a lot more work since the parts of the old deck which they thought could be reused actually needed to be completely redone from scratch… which they said was not my fault so they were not going to change the jobs cost after it had been agreed to, which I thought was very honorable and refreshing. I am very pleased with the final results and absolutely am happy to suggest them for any deck work you might need. They also cleaned up after themselves and were very attentive to the details I wanted them to match to the original houses look. My home was built in 1880 and I wanted it not to look like a random addition but part of the original plan. They did a great job!"
