Wow!! Just incredible selection and amazing turn around time from template to install! Everyone is very communicative and thorough! The laser tempting is exceptional and allows for such a precise measurement! Each kitchen we’ve done with Keystone has turned out just beautifully!
We are so thrilled with our Bellini quartz countertops. Keystone had a fabulous variety. Every part of the process was professional. Tuba guided us through our selection and was very knowledgeable. The measurements & cutting were spot on, and Oscar and his assistant, Lolorio, did a fantastic job installing.
I discovered Keystone Marble and Granite after visiting several other vendors for my kitchen remodeling project. I was discouraged, not having found what I was looking for, at a reasonable price point. I was very impressed with Keystone's inventory, and the first time I toured through their showroom, I knew right away I found it! My new countertops are gorgeous, so much more than I expected, at a very reasonable price. Tuba and the staff at Keystone Marble and Granite were great at communicating and making sure I knew exactly what to expect. The best experience in my entire kitchen remodel! Amazing!
