Grout and Tile Cleaning: Mr. Happy Grout uses a non-toxic neutral cleaning solution on your tile and grout so it's safe for your family and pets. Our tile cleaner penetrates the pores of your tile and grout to loosen embedded dirt and oils. The tile cleaner is then extracted with a high heat and high presser truck mounted unit. After all the solution, dirt and oils have been removed from your grout and tile surfaces, Mr. Happy Grout then applies a sealer to prevent future build up. To finish the job, this father and son team performs a final clean and buff to the entire surface to remove residual residue and ensure that your tile and grout look like new!
