Q: Does G.M. Marble & Granite have its own countertop fabrication facility?

As part of our independent research, we attempted to determine whether G.M. Marble & Granite has its own natural stone countertop fabrication facility. Our analyst contacted the company as a mystery shopper, but unfortunately, we were unable to obtain a clear answer — the calls and messages either went unanswered or did not provide the necessary information. The absence of confirmed data about fabrication should not be seen as a negative sign.

Yes, based on the results of our research, G.M. Marble & Granite offers discounts for veterans — this information was confirmed by a company representative during a conversation with our mystery shopper. We believe this isn’t the only discount available: like most participants in our rating, the company may offer personalized terms — especially during national holidays, seasonal promotions, or for large-scale projects. We recommend confirming the details directly: submit a request, call, or message the company through our website — and don’t forget to ask about current discounts. In many cases, contractors are open to discussing individual terms.

Q: What is the price category of G.M. Marble & Granite in Vallejo, CA?

Unfortunately, as part of our independent research, we were unable to obtain pricing information from G.M. Marble & Granite. Our mystery shopper attempted to contact company representatives to request a quote for the fabrication and installation of a stone countertop measuring 83.4 square feet. However, they were either unable to reach anyone by phone, or never received the promised estimate after the initial conversation. We want to emphasize that the lack of response or data does not necessarily reflect the quality of the company's work. In our experience, some contractors are simply unable to respond to all inquiries in time or prefer to discuss pricing only in person. To get accurate and up-to-date pricing for your project, we recommend reaching out to the company directly through our website — submit a request, call, or message them — and ask for a personalized quote.

Called for a specific countertop they had on advertising. I went there and it was a different slab not the one they advertised. Very disappointed I drove 45 minutes there and 45 minutes back.

I cannot say enough about GM Marble and their staff. I had issues with a couple of contractors that I had to let go and was up against the wall when it came to the timing of getting my slabs from the vendor. I found GM on Yelp and decided to give Brian a call based on the reviews. He called me right back and his calm and assuring manner made me feel like I had finally found the right crew. That definitely showed when the first delivery of the slabs to their shop turned out to be slightly different shades. It was not something I noticed with my untrained eye, but both Cinthya and Josh there pointed it out and even went so far as to bring both slabs outside in the sun so I could see the difference. It was hugely disappointing but the vendor said they would send two more slabs as soon as possible. Sadly, those slabs did not match either! I believe it was GM's expertise and professionalism that save me from a big headache of having the two slightly different slabs installed right next to each other. In the end, the vendor sent six slabs to GM for them to pick out two exact matches and they found two bookmatched slabs that went together really beautifully. GM did an amazing job of seam matching a very bold veining pattern. Plus they did a great job of protecting the space during demo and clean up afterwards. I plan on using them again when it's time to do my bathroom countertops.

In the middle of a very large remodel, GM Marble was recommended by our Contractor. The scope included two indoor kitchens and one outdoor kitchen, a pantry, two bathrooms and a laundry room and incorporated 8 slabs of Granite and 2 slabs of Quartz. The GM Marble team handed all of the materials from various suppliers, created templates, and walked me through (advised, cautioned, recommended, celebrated - because they are experts, and I had never had new counters installed!!) the placement and seaming, and their team spent all the time needed with adjustments to ensure I was happy with the placement and final design for fabrication. Their delivery teams were on time, worked long days, very pleasant, and always ensured we were happy with the end products. The installation exceeded my expectations, and our home looks lovely. I would definitely recommend GM Marble to anyone embarking on home projects.

Brian and his team came highly recommended by my neighbor who'd just completed a major high-end to studs remodel in Lafayette (we were about to do the same). I've flipped a handful of homes and dabbled in development in the past - the key to a great project are the people / vendors / partners you leverage. Brian consistently went above and beyond - I initially purchased 3cm slabs due to the complexity of the install - only to find out that my cabinet makers hadn't planned for it. Brian made some calls / pulled some strings and was able to swap out 3 slabs w/ his vendor (this speaks volumes to how folks in the industry see this company) - His scheduler and installers were on point throughout the engagement. My understanding is that Brian is a second gen stone and countertop guy - his dad taught him the ropes and did an absolutely great job. The install team came back to polish the counters once construction died down and even filled a small chip in a custom sink I'd purchased from overseas. When I tried to pay for their time they politely declines (several times). Guys, THIS is what it's all about - leveraging others to take the stress out of a traditionally complicated, spendy, and time consuming process. Cannot recommend this business enough, THANK YOU!

This fireplace slab is our second project with Brian and GM. A few years back they cut and installed a countertop for a bathroom vanity. It was a built-in - it had to fit between two side walls - so had to be very accurate. It has been several years and still looks great. The fireplace slab (the walls are not yet painted and there are drywall patches from other work we are doing) is a whole different level of work. Our slab is about 10 feet tall - which is very hard to find at the height. It took 10 people to lift into place. If you are looking for a great fabricator, GM is your place. If you are doing a slab and want further information, read on... For us, we did a heavy amount of research on slabs - both via social media to get feedback on pros/cons and research into fabricators. The biggest issue with slabs is that they crack in time - mostly, if not installed correctly. We contacted GM as we had great experience with them on our first project, but we also contacted many, many more. We contacted fabricators in the bay area that stated they did granite, fireplace slabs. When we looked at their work, they often had one or two jobs with vertical slab work. We only found two that had multiple jobs - GM being one of the two. If you are doing Slab work and you ask the fabricator about how they secure the slab, how they cut the opening for the fireplace, and if they do seams you will get a better example of their experience level. GM has quite a number of vertical Slab jobs they have done, maybe 7 or 8 (more?) in their portfolio. That may not seem like a lot but most have 0 to 2 that we spoke with (we contacted maybe 12 fabricators). Brian has a lot of experience with these type jobs and it shows when he discusses options. Depending on the type of fireplace insert you choose (electric or gas) you may be okay with an opening with 90° corners, but if you have a heavy slab (we did), clay soil (we do - lots of movement), and a gas insert (we do, high heat... electric fireplaces typically are show only and do not output heat), then how you approach the slab matters. We have eased corners in our opening, a horizontal seam to offset the weight and hidden anchors to secure the slab to the wall (really wooden framework/cement board anchored to the wall, not the wall itself). They also glue it, but the anchors assist. We also have side pieces to our slab that wrap the sides of the underlaying frame. These are mitered at 45° to the front slab. In person, it looks like a 3" thick slab and not that we have mitered side pieces. So if you are looking to do a slab, make sure you talk to Brian as experience matters on this type of not inexpensive install.

Another phenomenal job by Brian and his team of installers. From start to finish he was there to walk us through the process step by step. I run a small handyman company (Robs Odd Jobs) but I know when to hire and sub out a project- even if it's at my own home! Brian's team were phenomenal. He hooked us up with some gorgeous and low maintenance quartz counters which are much higher quality than anything at granite expo (they use cheap Chinese quartz). His guys were always on time, protected the home, were polite and professional, and cleaned the house better than it was when they walked in. He worked within our budget. We shopped other places and the quartz alone was $8,000. He got us the counter tops, the demolition labor, dump fees, layout, material and installation ALL FOR LESS than what the material alone was going to cost us of the competitors. Highly Reccomend them to all our friends, family and clients of Robs Odd Jobs. We are a top rated 5 company and we only refer the very best! We hold all our sub contractors and referrals to the same high standard and we are proud to refer GM Marble and granite with the upmost confidence!
