We had a problem with black stains on the caulking along the edges of our tile shower stall. We’d been using an ineffective cleaning product and by the time we switched to something better, it was too late. I didn’t trust myself to do a good job recaulking, so we called Chuck at Superior Grouting Services based on a recommendation. Our experience was good. He did very good work, and recommended a good cleaning product too. He didn’t overcharge, nor did he try to sell us on unnecessary extra work. If grouting/tile needs come up anywhere in the house again, we’ll definitely call Superior Grouting.
