We recently worked with GNS Stoneworks to install our new kitchen countertops and are extremely pleased with the results and service. Our drop in cooktop was challenging due to the knobs in front but GNS knew exactly how to grind the backside to allow for knob clearance. The minimal joints are almost invisible and their workmanship is excellent. Would HIGHLY recommend GNS.

GNS supplied the countertops and shower surround for our recent kitchen and bath remodel. Even though we made several changes in our choice of material they were flexible and worked with us. The final result is beyond our expectations and we couldn't be more pleased.

It was very easy to work with Nathan and team at GNS. We wanted a stone countertop and backsplash. They were able to cut the back splash so that it fit perfectly against the cabinets trim work. During the install they were very responsive and helping to make sure all the appliances fit in with the very tight tolerances we wanted,

We did a full house remodel requiring numerous countertops throughout kitchen, baths, garage, plus smaller areas, many requiring precision cuts. Nathan and his team were easy to work with, professional, and the completed work was excellent in quality and appearance. Following the remodel, Nathan completed other small jobs at the house and, as always, in a timely, efficient manner. I highly recommend the GNS team.

Nate Synder and the GNS Custom Stoneworks team are absolutely world class! Look no further because this is who you need to go with. I could not imagine a better experience. Nate and team came highly recommended and he WOW'd us throughout the process. From the initial discussion to help us determine the right type of stone to go with to post install to come by and review the work by his team, it was a white glove experience the whole way. This was my wife and I first countertop project and it went perfectly! We ended up going with quartz because we were concerned about stains and scratches along with low maintenance. Nate did a great job at explaining the pros and cons of each stone type and recommending what would be best for us long term. In fact, he even had some extra stone of the two pieces we were undecided about and after bringing them home, we were 100% certain of which to go with and we were not disappointed, Unique Calacatta. If you are looking for a team that is thorough and going to make every effort to exceed your expectations, GNS Custom Stoneworks who you need. I learned that they use state of the art stone cutting technology to maximize as much of the stone on the slab you buy. We were able to get our entire kitchen AND a window sill surface with one slab of stone. Not only that but this advanced laser technology they use was able to cut the slab to where we only had one seam to put all the pieces together. That is right, from what you see in the pictures, you can't see the corner on the other side of the fridge where we needed that seam, there were a total of 4 pieces! Absolutely amazing how they were able to cut out the sink and use one long piece for the long view pic you see attached. The polishing of the corners and edges couldn't have come out better, see the attached pic. One thing you will notice from our kitchen is our sink. When Nate came to take measurements and talk to us about the look we were going for, he was able to educate us on things we were not even thinking of that would be a "gotcha" in the future. Specific to the sink, due to the shape and placement of the stone, he recommended that it would be be st to have the slab go slightly over the edge of the sink rather than have it exposed like we wanted originally. The reason is because with water and time, the sealant will breakdown and end up getting nasty and not something you want to deal with in the future. At the same time, we were getting our cabinets remade and Nate worked closely in ensuring that all the measurements were right and he even pointed out some things our contractor did not catch when needing to build out the sink frame supports. Had Nate not been working with the contractor, we probably would have had a setback the day of install. His team arrived early and took every measure to follow COVID guidelines and were extremely clean in their work. They checked with us before leaving the job and as an added measure, Nate came by the next day to review the final work. One last note is that Nate was readily available a few days after the install when my wife freaked out about some stains the cabinet contractor made on the countertop that were not coming out easily. What happened was that his belt buckle had been rubbing up against the side and made it hard to get out. Luckily Nate called us back within the hour and walked us through how to get it removed using the right cleaning agent and cloth. He explained to us what happened and what to do in the future and not to worry. We love the countertops so much that we are already looking at doing our bathrooms soon!

Nathan and the team at GNS Custom Stoneworks were wonderful to work with. Our remodel included a dozen slabs, eight different granites, 14 sink cutouts, in 16 rooms, and each was fabricated and installed perfectly. Our timeline was delayed, and Nathan worked with us along the way to ensure that his team was ready to install the granite as soon as a cabinet was ready. Nathan's easy-going attitude definitely made everything go more smoothly. I would highly recommend GNS Custom Stoneworks!

I will never use anyone else as my countertop installer except for GNS! All of the employees are professional, knowledgeable, reasonably priced, and honest. They provided quality workmanship, communicated with me throughout the process and were reliable. Nathan even made some recommendations that improved the look of my master bathroom.

Nathan and his team at GNS were absolutely incredible. I was blown away by how fast and professional the process was. Both Nathan & his installers were a pleasure to work with and made cutting & installing countertops a completely painless part of our remodel. The quality of Nathan's work is top tier. Every single person who's come over comments on the countertops and how amazing they look. Nathan even went above and beyond to personally drill support holes for our pot filler in the backsplash when my contractor and I were a bit nervous and his installers shared some Dominos pizza with me while they were working. Just more examples of how friendly, professional and talented Nathan and his team are. 10/10!

GNS replaced the previous granite countertop with a beautiful dolomite product and cut down the raised bar to make more of an island. Nathan was terrific to work with and provided good advice. He was very responsive to all of my questions, and they produced the countertop very quickly. His team did a great job with the installation. I highly recommend GNS.

Nathan and team were very easy to work with and did a great job. We wanted the backsplash to seamlessly fit with the cabinets. They did a lot of nice little detail cuts to make it work.

Working with GNS Stoneworks was a pleasure! My new Silestone quartz countertops look beautiful and were so affordable. Nathan was able cut my countertop in one piece so it is seamless. He also was able to make my bar height countertop wider to make it more comfortable and give me more serving space. He coordinated well with my contractors; measuring, cutting and installing the countertops immediately after the cabinets were installed. Doing this without any downtime helped my contractor to install my backsplash tile faster. Nathan's good communication and attentiveness to the timeline aided in completing my kitchen sooner than planned. I highly recommend GNS Stoneworks for their quality craftsmanship and attention to accommodating customer service.

Nathan did an amazing job with my countertops--I am beyond pleased! I am a first time home owner and recently remodeled my kitchen which included Marengo colored Silestone counter tops. Nathan was extremely accommodating and guided me through the process from day one. I never felt that he was rushed or annoyed, despite my indecision and many changes throughout the planning process. Additionally, he was very professional and exuded competence and passion for his craft. I would highly recommend GNS Custom Stoneworks. Many thanks to Nathan and his crew for helping me in getting settled and loving my new home!

I have worked with GNS Custom Stoneworks on several occasions and every countertop installation has been outstanding. Nathan has an excellent eye for detail and is a true craftsman. My parents recently remodeled a very large kitchen in Liberty Hill, TX and Nathan and his crew did an excellent job installing Silestone quartz countertops. My parents wanted to use the existing sink as an undermount. Even though the sink wasn't designed as an undermount, Nathan was able to determine the best method and the sink looked perfect. I would highly recommend GNS for any kitchen countertop or remodeling needs. - Dale Malone Austin, TX

We entertained challenging granites as well as simpler ones and actually settled on the most mundane black, simple, regular grain granite that should have been a walk in the park to cut and install as seams should be imperceivable. It was THAT regular. The granite was cut and brought on side and installed. And then we noticed that in the most prominent part of the granite next to the range (right where we would see it everyday) there is a discoloration, bad filler, or some sort of really irregular pattern on the granite. Nowhere else on the granite counter top in our kitchen such variation exist. Nowhere. We contacted the company and asked what can be done. We were told this is natural variation of the granite -- a granite we chose specifically because it didn't have ANY variation when we looked at it on site in daylight. There's nothing that can be done except replace that piece which will most likely damage the backsplash and the adjoining granite pieces and will cost us 3K out of pocket. So the company takes zero responsibility for the fact, it is their job to deliver quality product, cut it strategically so it imperfections fall in hard to see areas and QA the work so that a faulty piece like the one we got should never make it to the client site. Oh no, somehow this is all the client's fault, cause I mined this slab out of the quarry and I was the one that cut it and installed it -- of course it's all my fault and I should pay to fix it. Nevermind the fact that this problem delayed the completion of our kitchen for weeks forcing us to live without a kitchen for a few more weeks. Needless to say I can't recommend this company to anyone that wants to end up with a kitchen or bathroom they love.
