It has taken me months to get around to this review (shame on me!) This service was worth every penny - what a difference it made to our basement bathroom walk in shower. The grout was an absolute mess - not cleaned or replaced since the 1970's. It was not an easy job as they had to do four walls plus the shower stall floor, and even the walk-in shower ceiling, which is tiled! They worked the entire day and now the shower looks like new. As well as grout cleaning, the calking along wall corners was replaced. Everything now sparkles. We would absolutely use this company again and certainly will in the future.
