From start to finish, the work done was first class. Overall, from measurements to installation, the job took about 2 weeks. Tina Sandridge (Chantilly) answered our many questions, and Mehmet, the contact person in the shop area was so very helpful when we ran into a bit of a problem (something caused by us, not the company). Installation was fascinating to observe. The finished product is beautiful: quartz countertops, island, and backsplashes.
