Excellent experience from beginning to end. Helen was great at executing the look we wanted for our kitchen with the colored quartz and design. She was patient with us as we changed our minds a few times an even cancelled the order to only return to process it because they are that great! Oscar was a pleasure to work with along with Delores and Raman (hoping I spelled your names correctly). I own a local kitchen, bath and basement business and I can proudly say they have all my referrals for my clients stone! Thank you so much. We are extremely happy with the quartz and the process.

We had a wonderful experience with Keystone Marble and Granite. Oscar went out of his way to find someone to level our cabinets. The office staff made arrangements for our backsplash to be installed the same day as the countertop. Eddie and crew were friendly, did an amazing job on installation and cleaned up after themselves leaving everything spotless.
Had a great experience with the crew at Keystone. Tuba(salesperson) took me from feeling overwhelmed by choices to getting exactly what I was looking for at a really good price. Actually helped me choose a lower price product that fit my needs perfectly, which is always appreciated! For those who want selection, Keystone seems to have double the selection of the 5 places I visited around northern DE. Highly recommend.
