After being provided with 2 options (full grout replacement or grout repair and professional grout cleaning), I elected to have only grout repair and cleaning performed. However, not all weak/recessed grout was repaired and in less than 3 months I had issues with mold build up. In addition, the grout cleaning was quickly becoming unmanageable. I contacted the Company and requested that they come out to inspect the work and assess why we were not able to maintain clean grout following the professional cleaning and repair. After the assessment, it was determined that the option for grout repair and cleaning should never have been offered, as the old grout was in such poor condition that it needed to be replaced. A fair credit was ultimately applied to the re-grout work given that the initial assessment incorrectly suggested the grout was a candidate for re-pair work. Each service (re-pair and cleaning and re-grout) was performed by two different servicemen, who were respectful and professional. I've only recently had the re-grout work performed, so I can't speak to the longevity of work, but I'm pleased so far.
