I have used Groutmasters twice now and have been very happy with the work they did (cleaning mold from shower, re-caulking and re-grouting) and the value for the amount of work they put into it. A year later we started getting some mold due to the configuration of our shower and since water doesn't drain well. I called to ask advice and they offered to return to clean the mold and re-caulk at no cost. I am even more impressed with their professionalism, the quality of their work and dedication to their customers. I would wholeheartedly recommend Groutmasters.
