I can't speak highly enough about my experience with the Grout Dr. Having tried to tackle the labor intensive job of regrouting I called the grout Dr. My call was returned that day and an appt. for an estimate was made within 4 days. Sean gave a detailed estimate of what he would do and a reasonable price. He came promptly when he said he would, worked all day , and left us with a beautifully restored and grouted shower stall. It looks brand new! What more could we ask for? Save yourself alot of work and hire the Grout Dr. You won't regret it!
