During our kitchen renovation, our contractor recommended we visit Pro Stone. He recommended it because of their good prices, large selection and speed of delivery.
We visited Pro Stone about five times and each time we had to wait for our sales rep for as little as ten minutes and as long as 20. The front desk receptionist is really nice and even though I'm sure this is the norm she would check as to where he was every five minutes. We didn't mind the wait too much because everything else about Pro Stone is wonderful, but if they weren't as great as they are it would have been a bad experience.
Our salesperson did a great job educating us about buying granite. First of all, the only difference between cheaper and more expensive granite is the supply. The rock is the same and it's the same thickness. Pro Stone has a handy list of all their granite with prices and their warehouse is open so you can go and browse these huge slabs of granite.
We wanted a bit of a deeper countertop and Pro Stone was able to accommodate us (of course for a cost, but that was expected). They were also able to accommodate a request we had for our kitchen sink hole. We wanted it closer to the front than normal.
The person who took our measurements showed up on time, was courteous and even let me check out his cool machine he had to take the readings.
The countertop installation happened SO FAST! I went out for work in the morning, came home at lunch and they were already done (our contractor supervised the install). We're so happy with our countertop - it looks wonderful, we paid a fair price and were treated very well by Pro Stone.
