GM contracting is a true find, not only are they professional perfectionist. They are loyal, trustworthy, and care about their quality of work. I use them for sheet rocking painting flooring Plumbing and there is not another contractor that can beat them. You’ll be glad you read this review definitely higher them. That’s the best.

Greg, with G&M Interiors renovated a bathroom for me. This was a gift for my daughter’s house. I was very impressed with how he replaced and repaired sub flooring that was sagging and his knowledge of structural issues that could’ve affected the tile job eventually. This bathroom was a total gut job. He replaced all the walls and floors with Durock cement board. I selected 2ft x 4ft porcelain wall tiles which he installed around the tub to the ceiling perfectly. We used the same tiles for the rest of the bathroom going halfway up and then capped it with a lovely Carrara Marble trim! The floor was done beautifully as well. He also included the painting with the job which saved me from hiring another person. I highly recommend G&M Interiors!

I contacted Greg to help repair/replace a shed covering our basement steps. He did an amazing job and it’s absolutely beautiful rerouting the concrete steps to the side of the house giving us our window back. He replaced our basement door and even asked what paint colors we wanted. High-quality work. Very professional and very well mannered, offered also a good price for the work that was needed. He also kept us informed on every step of the way. Thank you again!

Greg did an excellent job helping us with a leak in our ceiling today. He was professional, knowledgeable, and took the time to assess the issue carefully and explain what was going on. He was very helpful throughout the entire process and made sure everything was taken care of properly. We really appreciate his quick response and quality of work. I would definitely recommend Greg to anyone looking for someone reliable and professional!

When our old deck unexpectedly collapsed, it could have been an incredibly stressful experience. Thankfully, Greg stepped in and turned what started as a disaster into one of the best parts of our home.

From the very beginning, Greg was honest, knowledgeable, and easy to work with. He is transparent on pricing and explains the process entirely. He didn’t just rebuild the structure—he helped us reimagine the space, ultimately creating a beautiful sunroom that far exceeded our expectations. His craftsmanship and attention to detail are evident in every aspect of the finished project.

Throughout the job, Greg was responsive, professional, and always willing to answer questions or discuss ideas. He took pride in doing things the right way rather than the easy way, and that gave us a great deal of confidence throughout the process. It’s clear that quality workmanship matters to him.

The finished sunroom has completely transformed our home. It’s bright, beautiful, and has quickly become our favorite room in the house. What began as an unfortunate deck collapse ended up being an opportunity to create something even better, and that’s entirely thanks to Greg and his team.

If you’re looking for a contractor who is skilled, reliable, and genuinely cares about the end result, I would recommend Greg without hesitation. We are planning several other projects with Greg and look forward to him transforming our home even more!
