I had to post a review on a great local company: Stone and Tile Care, LLC in Reno. I contacted owner Jill Johnson through a referral and she immediately responded and came out to inspect and bid the job. Although they are booked two weeks out, she was able to accommodate our schedule due to an upcoming event. Two workers came out for different processes; both were on time, professional, and explained the process in detail. Highly recommend this company if you have any tile or stone maintenance needs. Price was based on time and material — seemed reasonable.
