I called Alpine for tile cleaning and sealing. It had been years. Pat arrived...so professional and prepared with mask and shoe coverings. Worked efficiently and did an amazing job. He also told me what I needed to purchase to patch some grout issues. Also what NOT to do. The price was very fair, and he was the best. He did all this while arriving with a flat tire. Alpine sent someone else over to change the tire while Pat was able to work on my kitchen. Highly recommend
