We hired Delta Granite and Marble to install some marble in our bathroom vanity and it turned out good. We were really happy about the quality but their pricing was a little deceiving. After we had picked out all the marble, they let us know it would be $60/sq.ft. and they came in and did the job. When we got the bill, we realized they had charged us $80/sq. ft.
Needless to say, we were a little upset and after we expressed this to them, they took a small percentage off, but not much. The work they did was nice and I would recommend them, but get a price up front so there are no surprises.
