JM cleaned my ceramic tile and grout. I have tan/beige grout in the kitchen and halls that had turned dark brown from years of family use. It was last cleaned six years prior and I doubted they could improve it much, I had tried several things on my own. Well... it is AMAZING, almost like brand new again!!! They were prompt, on time, were here less than 1.5 hours and my tile is SO much improved, it is unbelievable. Truly. Highly recommend! Very happy, and they communicate well, too! A+ business.
