Posted by Marilyn V. on 10/22/2020 Mike and his son Allen were top notch professionals. They installed outside metal window coverings on all our windows and repaired any rotten wood they found around our home. Fantastic job by both. I would highly recommend them for their great workmanship, value, and honesty. After the job, they cleaned up so well that you would have never thought anyone was here.

Posted by Michaela S. on 06/29/2021 We needed an outside wall replaced due to rot. JC responded to our inquiry quickly and was able to put us in the schedule quickly. They did a fantastic job replacing the wall, installing a sliding glass door and new windows. In addition, the living room was painted an a gutter was installed surrounding our deck. Communication was great. I would highly recommend them.

Posted by Michael C. on 12/07/2019 Jim and crew were friendly, professional, and highly skilled. He designed and estimated my job on the spot. He has a great system and if I mentioned I wanted a change he would document it and send me a change order immediately. He showed up when he said he was going to, managed subcontractors and took all responsibility. He helped me navigate both town permits and state wetlands permits. I could not recommend him more and I could not be happier with the process and results.

Posted by Sudie B. on 07/25/2020 We hired Bill to paint our house, but we got much more than just a paint job. We had done very little work on the exterior of our house and outbuilding in the 20 years we have lived here, and there was a lot to fix: rot, pests, and more. Bill not only paints, but does roofing, gutters, replaces windows and doors, and does electrical work. He is not only competent but caring. His cleanup job went far beyond our expectations. We would hire him again in a flash, and probably will!.

Posted by Cynthia M. on 07/18/2021 We have hired Ben and his crew for multiple projects, from small repairs to a beautiful deck, as well as a complete kitchen gut and remodel. Ben's attention to detail is impeccable. He continuously kept us updated with progress and milestones as well as possible budget fluctuations due to requested changes. We were absolutely comfortable with having the crew in our home while we were gone. We have been absolutely thrilled with each of the projects completed by Griffin Ridge Builders.

Posted by Susan L. on 06/18/2021 Costas and his team did a wonderful job on my Aunt's home. What started off as a deck repair, turned into so much more (siding, windows, new 1/2 bath). The house had been in a bit of disrepair and he was very thoughtful and thorough in his approach to bringing it back to life. My family and I will enjoy it for many years to come, and I truly appreciate some of the little things he did along the way to ensure everything was done right. He took the initiative to select things when I was not able to be there. It felt very much like he was treating as if it were his own home. His attention to detail was terrific, and he was super responsive. THANK YOU again!

Damaged part of ceiling directly below has been removed. Water test has been performed and source of leak has been found, although exact cause remains unknown.

Ceiling below and likely part of trim will need repair. Will then need ceiling and all trim painted. Need help hopefully before next rain as this is an active water leak, and without insulation or ceiling is now fully open to the bedroom.
