I found William R Bonnewitz Custom Tile & Stone Llc on craigslist and after googling the company and following buildzoom's advice by calling Trenton to verify that there were no complaints, I called him. As is usual, no one answered so I left a message. However, he texted back immediately that he would call me in a little while and did!
I had called several other tile companies and described my job: 22ft of wall tile above a standard size tub/shower enclosure. He asked a couple of questions about the space, gave me the lowest quote of 4 companies....and he was the only one that was licensed and insured (both liability and workman's comp).
Billy wasn't available for a couple of days but he showed up this morning at 8:05a as promised, started working by 8:15a and completed the job by 12. He was meticulous and left my place clean, clean, clean. Not a trace of dust nor debris.
I highly and without reservation recommend this company. I will call him again for the backsplash in the kitchen and to repair the flooring disaster created by a different company.
