Harrison & Shirley A., Milwaukee

Staff was always very polite, efficient and demonstrated expertise. Lisa followed through in a timely fashion with all details and even accommodated the job around the death of my father. She was very compassionate. So glad we changed our minds and chose granite. Thank you Lloyd for your kind assistance and for a great experience. It is evident you lead a great team.
Melissa V., Muskego

Fantastic experience! Brenda made the whole process a breeze. Our finished countertops were more than I could have ever imagined. We will definitely recommend you to others!
Gina & John R., Milwaukee

We couldn’t be more pleased with the whole granite experience. Chris was super to deal with—his talent and eye for design, not to mention his patience and time he spent with me was incredible! The rest of the install crew took the utmost in care and perfection in laying down the granite. Very personable as well, answering all our questions about care of granite, veins, etc. This was a very unusual design with curvy sinks and edges. Such consideration was taken in the fabrication of such a design. This turned out exceptional—beyond what we ever expected, all the way around from start to finish!
Jo & Don G., Muskego

The installation team treated our home as if it was their own. They were very respectful and took great care to do an excellent job.
Brian & Kris S., Germantown

The installers were very courteous, very respectful and friendly. They were confident and proud of the company they are a part of. Thanks also to Melissa who was very patient in my selection process and to Alex who did a very professional measuring job and communicated well with the plan he sent after the measure. Thanks to all the teamwork, it spells success!
Gail R., Brookfield

Alex helped us and gave us excellent suggestions which truly made the finished product beautiful. As always, a pleasure doing business with everyone at Keystone!

I haven’t had a minute until now, but wanted to let you know how incredibly beautiful this bathroom is thanks to you and your wonderful employees! You have all been amazing to work with in your attention to detail, your punctuality, your workmanship…amazing. The stone is absolutely stunning!

We wanted to thank you and the entire Keystone team for the wonderful granite countertops. They look beautiful and we could not be happier. It was a big purchase for us and you guys did a great job in making us feel comfortable with our decision and confident that the final results would look awesome. Our existing plumbing and counters were in poor shape. They made the necessary repairs and adjustments. Besides being very friendly and respectful, both are very hard working, talented installers. The seams are nearly invisible and the counters perfectly level. Everyone that has seen our new kitchen is amazed by how gorgeous the granite countertops look!
Michael & Linda D., Lindenhurst, IL

What a professional group—polite, worked non-stop, answered my questions cheerfully, just fantastic!
Allen & Cyndy, Oak Creek

They were very respectful. They had to remove an existing counter and sink and they did so quickly, quietly, without damaging anything. I am so pleased with the people in your company and the professional manner in which they present themselves. Great job!
Dianne J., Cedar Grove

Everything was done very professionally. Other competitors were vague and late with estimates and estimates were high. We are very pleased with our project.
Betty & Neal M.

Your team was on time, protected our floors and wood work, cleaned everything up, never even took a break—just worked until the job was done—perfectly! We needed a soap dispenser and it was delivered to our home the same day! We really appreciated your beautiful well-organized showroom. Very well done. And the take-home samples are a great idea.
