RISSCO did a fabulous job installing new countertops in our kitchen. Liz in the sales and estimates department was knowledgeable, professional, and patient in explaining options and in writing up the estimate. She did an excellent job of communicating by phone and e-mail, and in advocating for us with Dupont, the manufacturer, when there was a problem with the new Corian color we had picked for our counter. The gray “Stardust” pattern, a new color by Dupont, had a directional aspect to it like the weave of a carpet, which Dupont did not explain to RISSCO. When it was installed, the two pieces of the counter at the seam did not match up well. Liz helped us resolve the problem with Dupont, and the installers from RISSCO came back and re-installed a section of the counter at no cost to us. Don, the installer, was polite and friendly and did an excellent, careful job. The mobile-fab truck, where they fabricate the counters in your driveway, is also pretty cool. We love our new counters and sink and highly recommend RISSCO.
