BEWARE: Luis drywall or sheetrock mostly advertises on sfbay area Craigslist. He claims to be a sheetrock drywall expert. I hired him to sheetrock a brand new 3000 sqft home. He took most of the money and abandoned the job . The work that he did was so shabby that I had to hire someone else to redo all of his work. His workmanship is absolutely horrible. The finish is really bad and all sheetrock seems are showing cracks at joints. Feel free to contact me with any questions and I will be happy to tell you more about his work.
