Coit came over within a few days of my calling to take a look at my grout situation. We just remodeled the house and had new floor tile plus the old. The old tile grout was dingy and discolored....used and abused for 10 years by the previous home owner. After evaluation, Coit's Angel came and made the old grout look as good at the new. We were very pleased with the result and with Angel's professionalism. He was on time, explained everything, did the restoration thoroughly & efficiently. All and all a great experience and we'd do it again.
