General information about Cornerstone Granite
Do you need to replace countertops due to fading or swelling? Chipboard countertops tend to lose their appearance and physical integrity under the influence of water, friction, or heat. This is not the case for stone furniture. Stone countertops never fade or swell; they perfectly withstand all sorts of negative environmental impacts. Moreover, they preserve their original appearances serving as interior decorations. Cornerstone Granite produces custom furniture based on clients’ demands. Designers make individual projects, and craftsmen process slabs to embody templates. The service price includes mounting.

I decided that I wanted to update my countertops by switching from granite to quartzite, but as I started shopping around I thought I’d have to hold off based on pricing. Luckily before I stopped looking, I asked around and was told to check out Cornerstone. My husband and I went, and their prices were so much better and within our budget. We immediately found one we loved. We started talking with Sofia about it on a Friday, and by the next Friday, the new countertops were installed. From the showroom, to measuring, to the demo and install, everyone was great. Highly recommend!

Everything turned out amazing! I adored everyone I worked with at Cornerstone. Enrique is a gem! Everyone is so professional and knowledgeable. The turn around was very quick and the process was painless. My island is one piece which was very important to me and Cornerstone made it happen. Their pricing is very reasonable and you can tell they care about their customers. Thank you for everything Cornerstone!

Cornerstone promptly arrived at my house with lazer measurements. The installers were efficient and courteous.
The pricing was extremely competitive. One of the things I like about corner stone - their slabs our in-house you’re not sent to another yard to browse them and have to deal with two Companies.
When everything is perfect you don’t know what kind of company you’re dealing with, but if you have a small problem and that problem is resolved - the company Deserves a five star Rating!
Enrique in the retail end was easy to work with and I really appreciate him.
Yes I would recommend corner stone to my friends and family!
Make sure you seal your granite because they don’t!

After a builder gone bad our new builder put us in contact with Cornerstone for our countertops in our new build- we met with Ramon @Cornerstone one afternoon made our selection and had them installed a few days later. Guys did a fantastic job cleaned up after themselves and left us with a beautiful product &experience. We couldn’t be happier with our selection and the Cornerstone team!
Thanks so much Ramon!

Wonderful experience! Making the choices of materials was a pleasure. Enrique & Rodrigo very engaged and helpful. Each and every one of the installers were excellent at their jobs. They worked efficiently and neatly. In just two days Baltazar & Jose transformed my kitchen (and my attitude) dramatically!
A tiny mishap left a small bit of damage to the room. BUT, if you're wondering whether they stand by their jobs, don't worry. They took care of it immediately in the friendliest way.
We're HAPPY customers!

My experience with Cornerstone Granite was excellent from design concept/planning to install. Cornerstone did the counters, backsplash and island install for the kitchen on my new build condo; they also did our 3 bathroom countertops, bringing a high level of quality, detail and excellent customer service to the experience. In the end, our vision came to life and we couldn't be more thrilled with the results. Thank you, Cornerstone!
Review #2 - I reached out to Cornerstone for remnant stone for a table top and i couldn't be happier with the end result. As always, great customer service - they even delivered and installed the stone at no cost which was fantastic.

We looked at a few places before settling on Cornerstone before redoing our kitchen and bath. Enrique was awesome in helping me select the counters. The quote was fair, install was quick, and they did a great job. Everything looked fantastic. Even better - we had a chip and repair issue six months later and Enrique had men there repairing it within hours. You can’t even tell where the chip was. Highly recommend Cornerstone!

***2021 Update**
We loved this company we decided to go back to them again for our bathrooms in our new house. We worked with Monica who was very helpful and professional!
We told Monica our budget and she worked with us to get a slab we loved. The crew was very professional and cleaned up nicely.
We will definitely be going back for the 3rd time to get our new kitchen updated!
Highly recommend!!

I met with Luis on a Saturday. That was the first time we walked into the Slab yard. I told him our price point and he completely understood. He did not try to up-sell or pressure us into buying something out of our price point. In fact, he showed us options that were within in our budget and had us leaving very satisfied and happy! Luis is a very friendly guy!
We made an appointment for the estimate the following Monday. I have a quantitative background and did the math prior to Luis coming (including the waste (10%) and tax), and Luis was spot on. Luis answered all my questions and made helpful recommendations with the cleaning and edging.
And then installed the granite that same week, on a Saturday! Very professional Job!
From the time we saw the slab to install was 7 days! I would recommend Luis/Corner Stone to anyone!

What a transformation our kitchen has gone through thanks to the new countertops. They really updated the kitchen. Cornerstone has great prices and trustworthy employees that will treat your house like there home. I really appreciate being able to leave my animals running around the house and know that they will watch out for them and make sure not to let them out. Can't say enough good things about Cornerstone. Now on to our master bath and I can wait to use them in there too.

Cornerstone Granite is top notch!! We just had the quartzite we selected installed on our kitchen countertops yesterday and also a bathroom vanity top was installed. They look amazing!!

I had two Granite companies tell me they weren't interested in doing the granite remodel I needed for my kitchen because they couldn't possible match my existing materials and it wasn't a job they wanted to do. Thankfully I found Corner Stone, they were amazing! They came out in one day, assessed the job (not your standard project) within hours gave me the price and started the job and completed it just a few days. Absolutely fabulous job done by highly skilled craftsmen. A rare find these days.

I needed a special cutting job for two items I'd bought elsewhere and was directed to the location where that is done. The staff was very kind--I have bad arthritis and walking, standing, and the heat were messing with me--and had me hang out in the AC break room while they sorted things. I really appreciated that and the hard work they do all day long under difficult conditions with potentially dangerous tools.
They did the cutting perfectly, checking with me several times to be clear on what was needed, loaded everything back in my car, and even did a little extra work at removing some plastic bits from the units that I did not need.
My phone contact with the main office on S. Fwy was also pleasant and informative. I stopped by to pick up my receipt and was impressed with the selection of products they have. If I was not renting, I would be looking at their stock for sure. Again, the staff was very nice and kind. If I have future needs in their line, I will be back.

First I need to apologize to CORNER STONE GRANITE & FLOORS for waiting so long to write this review.
I waited really to long for make this review because I couldn't find words good enough for these guys. I still can't, but I can't wait anymore. I want to write good review, the best review, excellent review, because these guys deserve it.
I decided to upgrade my kitchen back in November 2016. Louis came to my home to take measurements and they cut all stone pieces in shop. Louise's 2 guys did installing job in less than 8 hours (9A till 2:30P). They brought all parts of countertop prepared in shop. Minor cutoff and grinding they did outside so no any dust or dirt produced inside home. And very important: Cornerstone do this job in almost half price less than nearby Home Depot for same kind of stone. You can go to compare before making decisions.
Before I decided to hire cornerstone, I read some reviews about this company and I looked first for bad reviews. First of all be aware there are two companies with very similar name CORNERSTONE GRANITE & FLOORS(this company) and Corner Stone WEST Granite & Floors. One review called for bad work done bay these guys (next is copy of that review):
"albert gaber
a year ago
Rock and dust smoke in the house after granite cut in my house Now I needs silica remediation restoration service. Feeling sick after incident STAY AWAY FROM THIS COMPANY YOU WHOLE FAMILY WILL BE SICK not a safe contractor."
This is so untrue for this company. Louis told me they even didn't do any job for this guy (he probably hired another company with similar name).Cornerstone ask him to remove his review, but he refused because who knows what reason.
On the end you will get quality for a half price from this company compared to others.
THANK YOU CORNERSTONE GRANITE AND FLOORS

From the time they came to my house to measure and the installation took only a week. They are punctual ,professional and are very proud of their work . Always willing to please their customers.

Went to Cornerstone to look at stone for the bathroom and kitchen. Friendly service, walked me through the options. Ended up settling on me agreeing to visit their slab yard in FW for a smaller piece of stone for the bathroom vanity. Went a few weekends later, and quickly found just the right piece. A few weeks later the slab was installed, with the sink I provided, and existing faucet (new'ish). Paid ahead of time, and crew showed up two days later to install. Team was conscientious of the mess they were making, swept and vacuumed, while hauling the old counter-top away. Perfectly installed, the faucet and handles are at just the right spot. No extra caulking or junk overflowing (squeezed) where you could see it. I highly recommend Corner Stone, and their team of installers -- Roman and Will. Next up, kitchen ... and I'll be visiting Corner Stone again and asking for the same install team.

Sold me marble and pretended it was granite. I went in looking for granite, explicitly told him I wanted granite for my commercial application and that I couldn't get anything else. He then says, "This style would be great for you", never once telling me it was marble. Even my invoice said granite on it in twelve places. It has the product listed as: "granite slabs: open marble horizon". I thought it was just the style or name of the granite, especially given the deceitful way it was listed. After I noticed a bunch of scratches and chips, I asked why the "granite" was doing that. Only then he said, "I never said it was granite." The whole time I was there and throughout all of my communication via text and phone, I kept calling it granite and he never once told me it was marble. I don't review companies very often, but when I do they are either awesome or horrible. You can guess which one this is. Beware of the bait and switch. I was charged $35 a square foot for two centimeter granite with no rounded edge. Cabinets poorly aligned and sink poorly installed. Glue want cleaned out of inside of sink either.

You get what you pay for. I had my kitchen and wetbar done by this group.
1. They do not 45 degree angles
2. They can not adapt to older homes where things may be out of square
3. They dont keep their word
I got Golden Crystal for my kitchen. Picked the slab, but my sales person was not there. I only picked 1 slab not knowing I needed 2. They picked the 2nd for me without telling me. What was installed had horrible straight lines running through 1/2 of it and now I have veins that are crumbling. They said they would fix the problem - now they don't return my calls..I have always used Tile, Marble and Granite and East side Marble over the yrs. I will not stray from them again.....

The absence of confirmed data about fabrication should not be seen as a negative sign. In our experience, it is not uncommon for companies to miss some incoming inquiries or choose not to disclose such details during initial contact.

However, like most companies in our rating, Cornerstone Granite may offer personalized terms and discounts on countertop fabrication — especially during national holidays, seasonal promotions, or for large-scale projects.

Does Cornerstone Granite offer cutouts for sinks, cooktops, or other elements?
Yes, like most professional contractors in the market, Cornerstone Granite 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 Cornerstone Granite provide for its work?
According to our information and industry practice, Cornerstone Granite, 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 Cornerstone Granite in any convenient way on this page to get the current terms.
