The staff at Keystone Marble and Granite are amazing! They have the best prices and a wide range of full size slabs compared to other places we looked at. We chose quartz & it is beautiful!! Also, their turnaround time is the fastest in this area. We had a new grand baby due to be born in 2 weeks and wanted the countertop done before baby is here. Told Sabrina and Tuba & they were like no problem. From signing of contact to installing took 10 days….amazing!! Thanks Keystone, we will surely be back.
