Stonex Granite And Quartz

I purchased a granite kitchen counter installed in 2013 and have been really happy with it. At the time the company was called Stonehaven Granite Works. Last month I noticed a gap between the seam of the 2 slabs. I called Stonex and they sent someone the following week (yesterday). The service rep stayed for 2 hours and fixed the gap and he also noticed and fixed a tiny chip in another part of the counter. At the end I asked him how much I owed. He called his office and came back to me with "Merry Christmas... no charge!" I was stunned, but he said he found that there was no reason for the gap to have formed (nothing dropped on it or the cabinet hadn't been moved), so they decided that the fault was not mine. Working with Stonehaven before and Stonex now has been a wonderful experience. I highly recommend them.
