We've worked with a lot of countertop and stone installers over the years, and United Granite stands out from the first time we worked together. If you're a contractor or builder looking for a reliable, high-quality stone partner, United Granite is the crew you want on your job. They showed up on time, communicated clearly, and took real pride in the transformation the granite and stone brought to each project. The quality of their work is consistent and seams are tight, edges are clean, and the finishes look great in every home we've done with them. From new construction to remodels, United Granite has proven they're easy to work with and professional from start to finish.

I can't say enough great things about United Granite! From Hannah in Sales to the crew who did the installation, everyone was exceptional. I appreciated the assistance in choosing just the right replacement granite for our kitchen and bar. We are thoroughly enjoying our newly revamped kitchen, and we highly recommend United Granite!

Excellent experience start to finish. Kamil helped me come up with a clever solution to a design issue and the cutting crew lined up the grain on the backsplash with the main counter surface so beautifully and unexpectedly. No regrets and all gratitude. Thanks!

We recently updated our kitchen adding new cabinets and countertops. We researched several places and found United Granite to be the most competitive and the best product selection. The measuring and installation was without any issues and everything looks great!

We've worked with United Granite twice and have really enjoyed the whole process. Their customer service, measuring, and installation teams are very nice. Response speed and turnaround time on the project are superb. And they have a great selection of granite and quartz in their warehouse. Would definitely recommend!

Halil at United Granite was extremely helpful and professional. He walked us through the showroom, offering us sample pieces that we could take home. Our countertops look amazing — his team did an amazing job. I highly recommend them. Great prices as well!

United Granite did a very nice quartz countertop installation for my kitchen. Everything fits perfectly. The whole team - the estimator, the measurement guy and the installation team were all friendly and helpful.

My husband and I would like to thank Kamil in helping us select a countertop and insuring the installation was done in a timely manner. The prices were more reasonable than the competitors we looked at in the area. The installers did an outstanding job installing the countertop with no damage to the walls while working within a limited area. We strongly recommend United Granite to anyone looking for a countertop.

Thank you United Granite for excellent experience during our new home constructions in Sanford. Their salesmen Kamil and Alexa were prompt, courteous, and accommodating from stone selection process to the installation. The turnaround time was 3-4 days once we went thru the stone options, pricing and accessories were finalized. We will definitely recommend anyone in Triangle area to pay their office a visit and decide yourself. Thank you once again!

Hannah, through her knowledge, made the experience of picking out my stone enjoyable. The staff — from the measuring to the installers and even the callback — handled everything in a professional, timely manner. I highly recommend United Granite Durham.

United Granite provided us with an excellent experience from start to finish. Their prices were more competitive than other options we considered, and the quality of their work was outstanding. Kamil was extremely helpful, guiding us through the selection process and ensuring everything went smoothly. The installation team was professional and careful, completing the job flawlessly without causing any damage, even in a limited space. We couldn't be happier with the result.
