Any suggestions for locating a contractor that specializes in installing epoxy sealers on an old garage floor? The installation service from Home Depot can't do the necessary repairs on the old concrete. The franchise that does decorative floor epoxy coatings is very expensive, since they do the fancy coating that is more than we need. The professional companies won't do residential projects. After seeing the video at http://www.thisoldhouse.com/toh/vide...047070,00.html, we don't want to try this ourselves. Who are the guys in the video? I'm in Cambridge, MA.
