Our shower is an almost fully enclosed unit (sauna-like) and the bathroom ventilation is too far away. Mould grows so quickly because of the humidity that no matter how much you bleach it, scrub it, re-seal the grout, it comes back within a few days. I found Grout Restoration Works in a flyer that got delivered to my home and decided to give it a try. It isn't super cheap, but worth every penny. Roberto Malagon initially came out to assess and provide a quote. He was timely, courteous, wore a mask (in these COVID times, it is important, took off his shoes etc.). We scheduled several weeks out because they were already so busy. The work arrived and was also punctual, courteous and wore a mask and took off shoes. It was a job of about 4- 5 hours. They sanitized, scrubbed, re-did the grout, re-sealed everything, cleaned the glass etc. The shower looked better than when we purchased the home (and still does - a month later already!!). If you have moisture or humidity issues in your bathroom and can't get rid of the pesky mould, I would HIGHLY recommend Grout Restoration Works. Not cheap, but again, well worth it. We were planning on renovating the bathroom, but now we can hold off and save the money for at least another year. read more
