Stained, loose or missing grout is a very common problem especially in showers and around sinks and counter-top backsplashes that are continually exposed to moisture. Mold and mildew can even grow into the sanded grout or become infused with silicone or caulking. In these cases, the grout or caulking cannot be cleaned and must be replaced. Don't scrape away at it endlessly - call us! We'll remove the old grout or caulking, clean, dry and re-grout or re-caulk. No need to worry about the color either we'll match it for you.
