Carpet dyeing is a process that re-dyes wall-to-wall carpet on location in homes, condos, offices and apartments. The process is clean, odorless, fast drying, and as permanent as your original mill dyes. Stains, fades, discoloring, and permanent soiling are no longer reasons to replace your carpeting. dyed carpet is beautiful in color, soft to the touch, ready for use in hours, and impossible to detect.
