I've seen a lot of granite installs and this was the worst. They were replacing granite on an existing island. The old top had cracked. A straightforward job. Very, very, very sloppy work....miscut openings, ragged seams, chipped granite edges. I can be very forgiving
but this was too much.
First they cut the sink opening crooked, off by a half inch and had to redo the whole slab.
After a second try they still got it wrong. The corners are wrong (round instead of square, chipped the granite edges where the seam meets and the sink opening is too small so the granite hangs 1/2 inch over the sink.
They had the new sink to go by and the old slab they were replacing was still in the garage which they measured for reference. Still couldn't get it right.
They came out 4 times and were late all but once. 3hrs, 3hrs, 9hrs late (they showed up at 6:49pm!). Check the pictures they speak for themselves. Save yourself the frustration and headache, go elsewhere.
