This is my second time using G&M Stone Tops for my home. The first time was a beautiful quartz remnant for my master bath. This time it was quartz remnants to create a sofa table, coffee table and 2 end tables. As the first time, it was an absolute pleasure working with this team. I placed my order to hold the materials, and it took me about 6 weeks to get the legs built for the quartz. There was lots of communication back and forth, and they were patient, provided the information I needed and were just great to work with. Once they came to the-late, my installation was within a week. Super fast!!!!!!!! I have 4 more projects that need quartz, and this is the only place I will go. I would give them 10 stars if I could!!

Look No Further!! If you are seeking an experience navigated by honesty, integrity, and know-how you have found the right people with G&M Stone Tops. Not only will they guide you to those perfect pieces within your budget goals, measure and provide expert tips for preparation on-site, they go above and beyond from start to finish. Big box stores can't touch these folks. As to their installers, I cannot speak highly enough. They were clean, professional, jovial, and took time to extend kindness and patience to my inquisitive kiddos (and husband!!). Endless gratitude to G&M for a job that exceeded my expectations; each morning brings me joy as I walk about my home beaming about all beauty that now surrounds me. Top Notch.

BEWARE of using G & M Stone Tops. Here's my side of the story. We hired a general contractor (GC) to install a new kitchen in our house. G & M Stone Tops was subcontracted by our GC to provide the countertop. At no time did we sign a contract with, promise payment to, or interact with G & M Stone Tops. The arrangement was EXCLUSIVELY between our GC and G & M Stone Tops. Now I'm not privy to the details of the contract between these two companies or the relationships between these two companies, and I don't know if G & M Stone Tops properly billed our contractor (I'm guessing not) but around March 16, 2022, I received a certified letter from G & M Stone Tops which was a "NOTICE OF INTENT TO FILE LIEN" against us. I forwarded the letter to our contractor to resolve. Interestingly, at no time did G & M Stone Tops attempt to contact us personally about sorting out this discrepancy. They went STRAIGHT to threatening to file a lien against us. (Personally, I think they were using us to get to our contractor.) --- Needless to say, our GC addressed this issue and from what I heard they don't use G & M Stone Tops anymore. ---Finally, we never heard anything back from G & M Stone Tops apologizing for the action they took. --- So, you have to ask yourself...do you want to do business with a company like G & M Stone Tops? A company that uses threats (NOTICE OF INTENT TO FILE LIEN) before even attempting to resolve an issue? What does it matter if they do good work if there is the possibility they will treat you like this?

Great service, working with Annesia was very easy and she was very nice and respectful. Francis and Tony installed the granite and did so in a clean and quick manner. Paul was also good in helping us out with the whole process. Overall, I recommend choosing these guys for any renovation project as they are easy to work with and understanding.

Does G&M Stone Tops LLC offer cutouts for sinks, cooktops, or other elements?
Yes, like most professional contractors in the market, G&M Stone Tops LLC performs cutouts and countertop preparation for various components — both standard and modern. According to our findings, these services are typically included in the overall project estimate. 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 G&M Stone Tops LLC provide for its work?
According to our information and industry practice, G&M Stone Tops LLC, 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 G&M Stone Tops LLC in any convenient way on this page to get the current terms.
