G.M. Marble & Granite - Antioch, California

Larry Schapker

On the weekends, we learned that visitation is by appointment only. We didn't have an appointment, but Brian saw us anyway.
Brian seems to be very passionate about what he does, and that's something we are looking for. We haven't chosen our countertop contactor yet, but they are definitely in the running.

Update:
Kitchen is not quite done. We're about 90% or more complete. G.M. Marble and Granite was chosen for the countertops and they did a beautiful job. THEY ARE GORGEOUS!!!
They were reasonably priced and a dream to work with!!!
Absolutely recommend them for your project!!!

Highly recommend Brian and his team! I used G.M. Marble for my kitchen counter remodel and the team was super professional, kind and executed the project seamlessly from templating, stone selection all the way through to counter and backsplash installation. The team was quick to respond to any questions I had and had tremendous attention to detail when taking measurements and performing the installation. Super happy with how my kitchen turned out thanks to the team!

It was a pleasure working with GM Marble to finish our new kitchen with quartz countertops and backsplash. They were very professional and paid attention to detail. The additional waterfall feature added a very attractive final element. We are very pleased with the higher quality materials, modern design, and clean lines of our new countertops and backsplash. We highly recommend GM Marble for any stone project.

I worked with Brian to spec out a potential countertop job and wanted to leave five stars for the depth of knowledge, patience, and great communication with the GM team. Unfortunately scheduling issues on my part prevented us from working together, but Brian would be on my short list of installers for the future. Clearly this is a family business with a tremendous passion and commitment to quality stone craft.

Install team was professional and quick. We had an issue with stains but after speaking with the owner, he came out to assist with cleaning technique and product and very quickly our issues were resolved. Appreciate the work and the service.

Highly recommend this company for any countertop job you have. The prices are very competitive for the quality of work that they do. The scheduler Cinthya, helped me out a lot when I ran into some time constraint issues with my personal and work schedule. There was no pressure from the owner Brian to do certain things-it was whatever I wanted to do. He gave great advice but also listened to what I needed and wanted. The two installers (Luis and Lee) I had were quick, quiet, very clean (put down catch-all paper tarps for their boots) no dust all over like I was expecting. Very professional company, they came and made templates first to be able to cut my countertops precisely and at their shop so no dust at my house before installing. I will recommend to anyone I know and use them on any future remodels.

Very helpful team! Cynthia took the time to understand our need and showed us around to the different options. Looking forward to completing a project with them.

FYI, directions are correct there, but the office door is a little hidden behind their slabs outside.

I was looking for granite countertop installer for quite some time and spoke with several companies. The explanation Cinthya gave me on the project details was comprehensive and made me confident that everything will be done properly. The price they quoted was very competitive.
Unfortunately, they are the specialized shop (countertops only) and I decided to go with another company , which cover other things like plumbing, flooring as well. But I''ll keep them in mind if I need some fabrication in the future
