8 Reasons Keystone is a Cut Above
- Buy direct from the fabricator–no “middleman” means you save big!
- Wisconsin’s largest showroom
We consistently receive accolades for our spectacular granite showroom, Wisconsin’s largest, with a full complement of natural stone and gorgeous granite slabs in a myriad of colors and patterns. The new lighting in our building allows you to see our samples up close, in truer color and even better detail.
- Hundreds of take home samples
We have hundreds of 5″x 5″ samples in every color and texture, already cut and ready for you to take home! Walk around and collect as many as you need. We do whatever it takes to make sure you make the right decision.
- Customer commendations
In the past year, we earned a “98.6 High Satisfaction Rating” from our customers. In fact, homeowners, builders and developers alike give us top satisfaction marks in ten categories, including manufacturing, installation, professionalism, and project turnaround.
- Fail-safe measuring
Keystone’s use of digitized measurement and CNC machining ensures perfect consistency, precision and an accurately finished project. A perfect installation every time!
- Hand polishing and finishing
Our skilled craftsmen take extra steps that other fabricators don’t. We hand polish your stone after our precision CNC machining, to ensure the smoothest, highest quality finish. On the average kitchen, this adds about 40 extra hours of labor–but we believe it’s well worth the extra time and effort!
- Our transportation technique
Keystone uses Barkow Stone Carriers to transport stone, marble and granite slabs. This handling technology is easier and safer than the more traditional method of loading and removing the stone from the bed of a box truck or pickup truck. The Carriers are at an ideal height for loading and unloading stone onto a dolly and are firmly secured for minimal cutting in clients’ homes, less breakage and fewer job delays. Stone is also delivered in heated trucks so your countertop is at the perfect temperature when installed by our Keystone employees, allowing the glues and caulks to cure properly.
- A “white glove” job site approach
No matter what the scope of your new construction or remodeling project, you’ll receive the white glove treatment from our installation crew. We cover your floors and protect your countertops with plastic. We also set up CAUTION signs to warn other contractors still working in your home.
