When it comes to adding quality stone counters, flooring, and focal points to your home, customization is key. You deserve to have a home with a look and style that's uniquely you and gives just the impression you want. At Cornerstone Granite Inc., we take pride in custom fabricating hard surfaces to fit your needs.
When you're shopping for quality countertops during your next home remodel, it's important to consider how long you plan to live in your home, as well as what other items you may want to upgrade. Typically, most homeowners include new cabinetry and backsplashes when having kitchen counters put in. If you're redoing a bathroom counter, you may also want to consider including tile or flooring in your renovation budget.
When renovating your bathroom, it's important to consider how you want your new shower to look, feel, and function in the space available. One of the easiest decisions to make will be choosing the right size for your shower stall, but the backsplashes, counters, and floors may be a bit trickier to decide on.
We offer an extensive line of stone materials and custom fireplaces that will complement any architectural style. From the warm glow of a limestone mantle to the unique and visually stunning color of onyx, we can custom create a unique look for your fireplace that you'll love. We use only the finest materials sourced from reputable suppliers in the area, and we'll take great care to ensure your new fireplace is safe, durable, and visually stunning for years to come.From old-world class to modern style, there's no look we can't recreate with your fireplace.

In 2019 my wife and I found Cornerstone in hopes of redoing a horrible installation from a different company. Cornerstone was able to measure, fabricate, and install the new countertops in a matter of 3 weeks. The original company took 3 months. Working with Andre was absolutely amazing and the quality of the counter tops was superb.

I have a horrible experience with this store. I had ordered the vanity top for the master bedroom, after making the multiple trip to find the design and color I like. The salesperson measured the slab and confirmed, it is the right size then marked as "sold". After a couple of weeks, they called to schedule the measurement and the installation. A guy came for the measurement, finally the installation day was scheduled.
The surprise came, just a day before the installation that the size of the granite was smaller, and they need to re-schedule the installation. Having said that, we had to go again to select the granite and repeated the same process. After a couple of visits, found the right size, took a picture and asked the sales person to confirm the size. Then a bigger surprise came when the slab arrived, first of all, that was a completely different piece not the one I had taken picture of. Secondly the vanity was smaller than the actual measurement and the technicians started cutting the drywall, so that they could align the sink holes with the sinks.
I asked them to stop it as there was no intention of cutting the drywall. They did not listen and cut it anyway. Then I called the store and spoke with the sales lady and the Project manager and explained there was no plan to cut the drywall and the slab is smaller. By that time the room was a mess, with a big cut on the wall, entire bathroom was filled with dirt and dust.
It took me multiple weeks to get over that mess. Had no strength or energy to tolerate that for another couple of months and asked them to fix it. After waiting for several months, they agreed to replace it with the correct size. Repeated the same process all over again, took picture, multiple visits to the store, finally the right size was installed but a different piece not the one that I had selected. The entire process took 8-9 months. Because of their carelessness and unprofessional attitude, I had to deal with so much stress. I would never ever go back.

When we were looking for a fabricator to help with a renovation project, we got several quotes and Cornerstone was by far the most competitive (by a long shot, really). We knew our project could be challenging as we wanted something quite specific, but Cornerstone was confident they could make it work. We worked with Karina, who was extremely knowledgeable, kind, and quick to respond.
When we had issues with a supplier trying to sell us a damaged piece, Karina was quick to answer questions and worked to find an alternative supplier that a) didn't significantly change our quoted price and b) had what we were looking for. While other companies took days to respond and schedule, Karina took just hours and got us on the books right away.
At the end of the day, our project turned out exactly how we hoped! We're thrilled with the work and the experience with Cornerstone, and can't recommend them enough.

Beautiful and precise workmanship. We bought a house a couple months ago and had it in our budget to do some kitchen renovations so we contacted Cornerstone Granite. After the initial measurement which they contract out, Andre (the owner) noticed some potential issues in the measurements provided to them. He took it upon himself to come out as soon as possible to validate the measurements himself.
After validating the measurements, he went over some options and recommendations regarding how to accommodate our apron front farmhouse sink, which was greatly appreciated. We were worried about how the leveling of our cabinets could affect the installation (previous home owners did some sub par work and I didn't want to rip the cabinets up and reseat them if I didn't have to) so he meticulously checked the leveling and assured us that while the leveling might result in one seam being a 32nd of an inch wide instead of a 64th, his installers would be able to accommodate any other leveling issues using shims.
That attention to detail and careful workmanship doesn't stop with Andre, though. The installers he sent over were just as hard working and precise. They were able to make the final cuts to accommodate our sink onsite and I honestly can't tell where the machined edges stop and the hand cut edges begin. Also, sure enough that seam Andre mentioned is exactly a 32nd of an inch wide while the other seam is a 64th.
That's a level of intuition born from experience that I hope to have in my line of work someday. We now have a gorgeous soapstone countertop that will last a lifetime. If we need to redo our bathroom counters down the road, Cornerstone Granite will be the only place we call.

I would recommend this place for your countertop needs. The front office staff ( Perla, Gaby and others ) were helpful and provided prompt and clear information. The installation crew was on time and the crew ( especially Chuy) worked with dedication to get the waterfall edges to look great. The owner Andre provides excellent customer service and came out himself to fix a few blemishes the next day. Overall I am satisfied!

We were looking into adding a breakfast bar in our new house, and went to a couple other places, but didn't really like what they had ( the ones we liked were a bit too much for a small space), so we went to Cornerstone just to also check out what they had there. Perla, was very helpful and patient, helped me and my husband with our questions, etc.
During the installation process, Andre the owner, was hands on, from beginning to end. We are very happy with the whole process, and loving our new breakfast bar. Thumbs up, and highly recommend this place! Thank you Cornerstone! Happy customer here! :-)

I was referred to Cornerstone Granite after exhausting my options at other major home improvement stores. I worked closely with Perla and Gabrielle to figure out correct measurements and pricing. The pricing was surprisingly better than other options and the finished product was flawless. I am extremely happy with their professionalism and the job was completed at an exemplary speed. I would recommend them to all of my family and friends. Thank you Cornerstone Granite!

I have used Cornerstone for a few of our projects and have been very happy with their attention to detail, ability to communicate well throughout the process, and provide excellent service in a timely manner. They were able to fit us into their busy schedule and go above and beyond expectations. We will be using them many times in the future.
