Why Choose Keystone Granite


Our Facility

Keystone Granite has fully embraced the technological improvements in the stone industry over the last decade, and our fabrication facility is no exception. Located around the corner from our air conditioned showroom, we have an 11,000 sqft state of the art fabrication facility. Production starts with our main CNC bridge saw which utilizes a camera and digital templates to automatically cut every countertop. We also have a second bridge saw for manual cutting. When a countertop is unloaded from the saw, it is transferred to one of four edge machines; which provide straight and consistent edge profiles. Intricate edges such as O’gee or edges with curves move to another CNC machine which has 48 different tools for shaping edges.

Keystone Granite is also one of the few granite shops in the area that has a waterjet cutting machine for inlays, custom designs, and exact placements of sink cutouts. Once off these machines, countertops go to skilled craftsman who work with water-fed hand tools to do final touchups and ensure nothing is wrong with the countertops.

With one of the most advanced fabrication facilities in the area, Keystone Granite brings consistent high quality work to every countertop job they perform.

No matter how complex the job, we can accommodate the customers wishes. We have done custom work with textured surfaces and honed surfaces. We have made granite signs and custom logos inlaid into the countertop. From commercial to residential and everything in between, we have the machinery, the personnel, and the experience to turn your dream into a reality.

Air Conditioned Showroom
We offer a complete indoor air conditioned showroom with hundreds of slabs for our customers to choose from. Who wants to be walking around outside in the Texas heat when they could be comfortably inside, where refreshments are provided, to choose their new kitchen or vanity countertops.
Consistent Quality
Keystone Granite handles their cutting, edging, sink cutouts, and most other countertop work with state-of-the-art machinery that ensures consistent quality. Coupled with artisans who strive for perfection and you have a countertop (quartz, granite, marble, glass, or other) that is of the utmost quality.
Digital Templating
In order to get the most value out of machinery that runs on electronic files, Keystone Granite has invested in a Laser Digital Templator. This allows for angles and hard-to-measure kitchens, bathrooms and other special projects to be templated with ease ensuring consistent quality fitting countertops.
Virtual Kitchen Layout & Design
Through the use of Slabsmith software, Keystone Granite allows the customer to see how their final countertop will appear, and adjust colors, shades, or other veins in a way that is consistent with their vision. See our dedicated Slabsmith page for more information.
15 Year Seal & Stain Warranty
Using an advanced penetrating sealer, Keystone Granite offers a fully transferable 15 year warranty that will keep every piece of natural stone looking as beautiful as the day it was installed. Call and ask for more details.
