"It went extremely well. Felipe worked on this quickly with another skilled worker (another great, talented, and friendly person). I'm extremely satisfied with the work. He went above and beyond. He's capable of doing everything, and doing it extremely well. I've known him for awhile, for a smaller job he did for my in the past. We live roughly in the same neighborhood. The project included some plumbing replacement, adding insulation, a small roofing project with associated roof penetrations, a brand new kitchen from some cabinets and kitchen hardware I picked out, flooring, floor leveling with concrete, miscellaneous electrical work and improvements to my existing routing (including adding some fixtures), coordination with his countertop subconsultant, plaster repair with drywall, and EXTREMELY good finish carpentry (I can't imagine anyone else who would take the time and effort to do what he did here) I hired him before, I'd hire him again if he'd be interested (it sounds like in a few months we'll have some more work lined up?), and I am recommending him to my other architect friends. He's basically helped me renovate a great majority of my house, and an addition I built myself."

He was thorough in his cleanup."
