Why Choose Keystone?

Your perfect room needs equal parts inspiration and creativity, plus a design feature that brings everything together—a focal point, a defining element, a keystone. Anyone can claim to be the best choice for new or replacement counters, but we prefer to show customers what sets us apart during every step of the building or remodeling process:

  • Passion for exceeding your expectations
    This starts with actively listening to what’s most important to you. It’s followed by offering you more than other providers, such as Wisconsin’s largest stone showroom and an unmatched supply of convenient take-home samples.
  • Meticulous attention to every detail
    At Keystone, we take pride in fabricating and installing stone countertops with exclusive techniques like precision CNC cutting and hand-polishing. We’re perfectionists with a philosophy of treating every surface as if it were being crafted for our own homes.
  • Relentless pursuit of excellence
    We’re constantly pushing ourselves to learn, experiment, and improve. This lets us apply the best practices to every project with offerings like an exclusive delivery method that’s safer and temperature-controlled for faster installation.
  • No surprises from start to finish
    We firmly believe that you can never communicate too much with clients. We keep you in the loop throughout every step of the project. We’ll tell you exactly what we’re going to do, then follow through on that promise.

“Our mission is to deliver uncompromised quality, service, and integrity to every Keystone customer. We ensure that they love their experience with us as much as they love their counters—and as much as we love making them.”

–Andy Wiegman - Owner

Atop a frigid ski lift at Keystone Resort, Lloyd Pickart chose the name for his new custom stone countertop business. What followed when he opened in 1998 was a renaissance of uniting great design with great stone products, making Keystone Marble & Granite the preferred choice among contractors and homebuilders.

20 years later, our commitment to quality remains under the leadership of Andy Wiegman, who became the owner and president in 2017. Andy is a veteran of the construction and real estate industries who honors our continued mission of delivering a superior way to add superior stone products to any environment.

As a premier fabricator of natural stonequartz, and other specialty surfaces, we create stunning countertops, vanities, mantles, tables, and wall panels for special places.
