We used Rock Tops for a whole-house remodel this summer because they had a stunning array of granite and the best prices in town. We selected (and gave a heft downpayment for) our slabs long before we were ready to install, so I was a little disappointed that when I called to schedule measuring, I was shuffled to the bottom of the queue. The lag between measuring and installation was very long, but maybe that's typical..?
Unfortunately, one piece was not measured correctly and one backsplash was missing. I talked them into leaving the incorrect piece in place so we could pass inspection and was told the replacement piece would be a rush job, ready in one week. Two weeks later I called to find out where it was. Finally, it was in, but I was again thrown to the bottom of the queue for an installation date. I complained to the head installation guy, who bumped me up.
Now, despite a few hassles (which was typical for the whole remodeling project with just about every subcontractor and especially the GC), we have gorgeous counter tops.
