I needed grout and tile repair (one tile was cracked and needed replacement) on my 1980 ceramic tile. Repairman was friendly, professional and very competent with tile repair. He also cleaned and sealed the tile. My ceramic tile looks new again thanks to the grout color matching process he undertook. I am so pleased! My neighbor wanted to call Hammond Knoll after she saw their work in my condo. Does anymore need to be said? Thanks for a job well done!
