Greg and his crew did a phenomenal job. We did a retaining wall, deck, gazebo and a wraparound seating platform around a tree for a very reasonable price. He always gave us an update on the work progress, sending us details on what was done, and pictures as proof. Every time they worked, they always left the place clean and tidy. We needed the job done by a certain date and he completed the project earlier. His team worked tirelessly and went above and beyond to complete everything; sometimes working as late as midnight, and always with a smile on their faces, especially, Dominic. The quality of their job is detail oriented and seamless. We value him, his good work ethic, professionalism and will keep him as our future contractor. We highly recommend him especially because he's so responsive, honest and hard working.

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!

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!

The review only lets you choose three out of five things to say that you loved about the contractor, but I wish that I could click all five because punctuality in responsiveness are also a highlight of working with Greg. It was such a breath of fresh air to get an honest contractor who was able to work with in our budget and give us a beautiful result. Greg was upfront the entire process with timelines and stuck to it even with the holidays thrown in the mix. We were able to get this job completed in a month and change. Greg is committed to giving you the best result possible and keeps you informed each step of the way with what is being done. No secret expenses or additional cost added on and a very generous timeline of payment throughout the process. I will definitely be using him for many more projects and I look forward to working with him in the very near future.
