We got kitchen and island counters fabricated and installed by MGS. Eddy and his team were amazing every single step of the way. The quote was accurate and competitive, communication was clear, and they were always on time. Our countertops were ready within a week of slab delivery. I was present all throughout the installation and they were very neat and meticulous. Our countertops ended up impeccable - you can barely (if at all) see or feel the miters or the joints.

Really liked these guys.
I was looking for a small remnant piece of marble or granite to cover the top of a little end table was only 2' x 3' and wasn't expensive.
Most fabricators quoted me crazy high prices for this -- 3-5 times more than the cabinet itself cost.
MGS charged a fair, reasonable price. Cut out the piece within about 30 minutes. And I was on my way.
Very good to work with. Highly recommended.

I'm a retired commercial construction superintendent and can recognize a quality contractor when I see one. These guys fabricated and installed granite kitchen counters for me in my kitchen redo. Eddy Franco, owner, checked all of the boxes with regards to professional behavior and was competitively priced even with Sacramento Valley contractors. The foreman, Miguel, was VERY competent and paid attention to detail, protection, and advised us regularly with regards to schedule. Very nice local guy as well. Excellent quality. The whole crew was fluent in English. I highly recommend this contractor!

MGS is THE place for anything marble, granite or stone. I've used MGS for my kitchen remodel counters (quartzite) and most recently my backyard counters (quartz). Eddy and his team are friendly, professional and their work is second to none! All of my lines are symmetrical and my edges were cut and blended to perfection. His prices are fair and reasonable and he is extremely responsive. if you need anything stone, you are doing a disservice to your project if you don't give MGS a call.

Eddy was incredibly responsive and very helpful, even though I had no idea what I was doing. He made sure I understood what I was asking for, and gave me a very reasonable quote. Besides that, he let me know that he could additionally offer other services such as demolition and plumbing, which for someone doing it on their own, is a huge relief. Highly recommend reaching out to Eddy for your countertop needs!

Eddy and his crew are great. He and his team are clean and meticulous ensuring every detail is well thought out from start to finish. We first sought his help with some rental properties and very soon he had more tasks we needed him to accomplish which most recently included a custom kitchen, remove old counters and backsplash and install a new one. Eddy did a great job. I highly recommend MGS!

A five star review does not do justice to the A++ experience I had with Eddy and his team. Eddy is timely, communicative, fair, fast, accommodating, detail oriented...this has been one of my best experiences with a contractor.
Eddy was one of a handful of contractors I met with to work on my kitchen project (changing to a new quartz counter top and installing a tile backsplash). I chose Eddy because, based on our initial meeting, he was prompt and clearly paid close attention to details. He also had competitive pricing that was fair and transparent (e.g. noting that we could have to change the cabinet plywood if there is water damage, and giving fair pricing ahead of time for that replacement).
I also really appreciated that Eddy had everything under one roof. While Eddy's expertise is stone working, he brought in the right people for ensuring that the new sink plumbing and tiling were done correctly.
When it came to scheduling the work, Eddy was accommodating and prompt. He made efforts to make my schedule work, which I really appreciated. He coordinated receipt of the counter slab from the store, and was communicating with me through the whole process.
During the construction process, Eddy was constantly paying close attention to detail. The stone layout and how the counter veins would "flow"; the sink logo location (wouldn't have even thought about this); ensuring that the seam in our counter was not at all noticeable...just to name a few. Really cared about every small detail, and clearly communicated along the way.
Finally (and this would be a sixth star if I could)...we noticed the sink was leaking a bit after the installation, and reached out to Eddy. Within literally 2 hours, he had someone at our house to fix the problem. Major kudos to Miguel. Thank you for the fast fix on a Sunday morning!
I wish every contractor experience could be like my experience with Eddy and his team. I will definitely be referring Eddy to friends/family, and giving him another call for future projects. Thank you, Eddy!

Eddy and his team did a great job on my countertops and island, he was also able to figure how to save me money by using smarter cuts that got me more surface area for the slabs I purchased from the countertop store. They did a great job on the backsplash as well, I highly recommend Eddy! Thank you!

Soooo..Eddie put it in my wife's head that we could have an all stone shower. My wife's dream is to live in a marble house, so when it came time for us to finish out second bathroom - we called Eddie to do the job. And we are glad we did! After purchasing the stone and shipping it to Eddie, he let me come and work with him on the layout.
Since we chose White Princess Quartzite for the material, it was very delicate due to the large crystals in the stone. During cutting one of the pieces broke and Eddie was able to repair it. He cut grooves for a metal support rod to strengthen the material so it wouldn't crack again.
Eddie and team had good suggestions for the layout and we were even able to save enough material for our vanity sink. He made two niches out of the material and it all look beautiful.
Eddie is very responsive and timely and was respectful of our home. He was able to accommodate last minute requests here and there, which was really nice.
Would highly recommend Eddie and team to anyone!

When it comes to stone work, Eddy at MGS is your guy. Working on a master bathroom project with my dad and we needed a stone installation service for the Quartzite we picked out. After reaching out to Eddy we knew we made the right choice.
Eddy has the attention to detail that you will want when it comes to stone installation. Him and his team will go the extra mile to match the veins or adjust the stone to your liking. In addition, he does a great job of explaining the work so you know exactly what you're going to get before it happens. Eddy and his team are punctual, safe, and very respectful. Not only that but if you have any questions or last minute adjustments, Eddy always picks up the phone or texts back right away making his communication skills amazing! He uses his extensive knowledge to give you advice and pointers to make sure that your project turns out better than you expected. It really is a no-brainer when you get this level of quality and expertise for a fair and reasonable price. The finished product far exceeded my expectations!
I will undoubtedly use MGS for my upcoming kitchen work! I highly recommend you call them and see for yourself.

Eddy is a true professional, his care and effort are clearly evident as the final product is gorgeous and my husband and I are beyond happy with the result. It is such a beautiful kitchen and bathroom and after living with it for years I love it even more! I would only refer people to Eddy and would trust no one else with this kind of detail work. He painstakingly went over every detail and matched every vein in the marble to get the look we were going for. Eddy went above and beyond and made the extra effort and took the time to achieve a perfect result. I cannot recommend him highly enough. Eddy made our kitchen and bathroom dreams a reality so thank you and your team again for a beautiful finish and a happy customer!!

Eddie and his team installed our kitchen counters. Not only are they honest, reliable and fantastic at their craft, but he is reasonable on his pricing, prompt to return calls and shows up when he says he's going to. I couldn't be happier with my counters and how well they turned out. His team is very nice and polite and they keep the job site clean.
I just had my bathroom vanity installed and stopped by Eddies shop to pick out my counter top. He was awesome and helping me figure out what would go well and has many options of remnant material to choose from. He is stopping by the house same day to measure for his template and start our fabrication.
If your looking for a honest, hardworking and fairly priced guy, MGS is who you should call.

Eddy and his team are artist! They were so nice to work with and had great suggestions on how to elevate my ideas. My kitchen and my bathroom are my favorite places in my house because of the slab and work that MGS Marble did. Eddy is a master of his craft. For example the slab around the hood (in my pictures) he really encouraged me to get another piece of slab so this could be one piece and there wouldn't be any seems. I'm so glad that I did. The veining is perfect.
I felt really lucky that we found him. If I ever build another house he will fabricate all the slab. You can not find another team that are such perfectionist and the prices are very fair. Highly recommend.

We wanted to make a custom dining table and had the table base. We chose the granite slab and eventually found MGS among couple other companies. Not only was Eddy the most prompt and efficient to respond and learn more about what we wanted to achieve, he was also very competitively priced. He promised to have it done within few days of receiving the slab and he did just that. Eddy and his crew were professional and didn't leave a mess. Definitely recommended!

Eddy did an AMAZING job for us with a small granite project. We were transforming a kitchen work desk area to a usable countertop with custom cabinetry underneath including a drawer microwave. The granite for that section of the kitchen needed to be cut and raised and then put back on top of the cabinetry to look seamless with the granite beside it, all the while ensuring that it stays in one piece. I spoke with 4 granite contractors and all of them said they could not guarantee the granite would come off in one piece and their price was a little on the ridiculous side. One of them even told me there was no tool to cut it right to the edge of the backsplash so therefore they could not take it off in one piece. Enter Eddy.
He responded to me promptly, came to give an estimate right away and his quote was very reasonable. He did a superb job! We can't even tell that there was ever a desk there. It looks and feels as if it was always one piece with the rest of the granite in the kitchen. I was so worried that the granite would break which would mean finding a completely new piece for that area that would not match the rest of the kitchen. Eddy assured me at every step that I had nothing to worry about and he had the tools and experience to get it done. Everything was done in a timely manner which was important because our cabinet contractor had been scheduled to come the day after Eddy removed the granite.
After the job was complete, we noticed that there was still a bit of a groove where the two granite pieces met. Eddy came back to fix it and make it smooth without a hassle. He even gave me tips on how to maintain the granite and what products I can buy to do it myself.
I HIGHLY recommend Eddy and his team. I can tell he has extensive knowledge in this line of work plus many years of experience. He is respectful and was a pleasure to work with.

Eddy Franco did an excellent job for me from start to finish to transform my dark/dirty kitchen tile into a brighter, lighter, beautiful surface. He promptly returned my initial call. He gave me suggestions on a good surface when he came to bid on the project. He found the manufactured quartz for me in exactly the style I wanted and even found the perfect kitchen sink. He demoed quickly and cleanly and installed promptly. I could not be happier with the final product. Everything looks great! Eddy is professional, knowledgeable, and clearly cares about his work. I highly recommend him!

It’s important to note that situations like this are not uncommon: contractors may be overwhelmed with work, prefer to discuss project details in person, or choose not to disclose information during the initial contact.

The standard scope usually covers cutouts for sinks (undermount, drop-in, or farmhouse) and holes for faucets or other plumbing fixtures. Additional cutouts — such as for cooktops, hidden or pop-up outlets, built-in wireless chargers, or other accessories — are discussed individually at the project planning and estimating stage.
It’s important to note that while the cutouts and countertop preparation are usually performed by the company, the installation of electrical and plumbing fixtures (such as faucets, outlets, or appliances) may not be included in their scope of work and could require licensed professionals. We recommend clarifying this point when placing your order.
To avoid misunderstandings, ask for a detailed estimate with a breakdown of all services: cutout pricing, installation, and any add-on options. This will ensure project transparency and help you clearly understand what you're paying for.
What guarantees does MGS Marble and Granite Services provide for its work?
According to our information and industry practice, MGS Marble and Granite Services, like most participants in the ranking, provides a workmanship warranty valid for 1 year from the date of countertop installation. This period is usually specified in the contract. We do not rule out that the company may have extended warranty terms (2 years or more), however, during our research, we did not receive confirmed data from the contractor regarding the duration and scope of its warranty.
The contractor’s warranty covers defects in fabrication and installation, such as uneven or separating seams, leveling and fastening issues, detachment or sagging of an undermount sink, flaws in edge finishing and cutouts, premature failure of seam materials, and cutouts that do not match the approved design. Warranty coverage does not include damage from use (thermal shock/burn marks from hot cookware, chips or cracks caused by impacts), stains and acid etching (for marble), wear due to insufficient maintenance or lack of sealing, natural characteristics of stone (veins, micro-pores, variations in shade/pattern within tolerances), shifts caused by base deformation, or any modifications performed by third parties.
The material warranty is provided by the manufacturer or the official stone supplier. Engineered quartz brands often offer a limited “lifetime” warranty for residential properties (subject to registration and compliance with care guidelines). For sintered surfaces, typical warranty periods range from 10 to 25 years. Natural stone usually does not come with a factory warranty — its quality of fabrication and installation is covered by the contractor’s warranty. The term and scope of the warranty depend on the project and materials — contact MGS Marble and Granite Services in any convenient way on this page to get the current terms.
