ISW did a high quality installation on my countertops. They are similar in cost to the other granite fabricators in the area and I didn’t have any rework, which I can’t say for some of the other granite fabricators I have used. The seams are almost invisible, and all the edges meet. I have only two small issues which do not have anything to do with the quality. 1) They tend toward a more traditional look, so if you want contemporary, you will need to specify how you want everything cut, corners, backsplash, etc. I ended up with severely rounded corners on my island, and even though they were cut consistantly and well, it does diminish the look I was going for. I wish they would have mentioned it. 2) I waited two weeks to get the counters installed, which is pretty standard for a small shop. I tried to get it pushed up, but they said they couldn’t do it. When the installer arrived, he said they weren’t busy at all. I can’t say whether only the installers were slow, but it sent a mixed message.
