We had a great experience with Rojas Construction. Our kitchen job was fairly complex, it was a complete renovation with new appliances, cabinets, and building out a new area and wiring for the washer/dryer. Plus it required access to and work in our neighbors' apartment. Rudy (the job boss) and the crew were fantastic. Rudy was especially great. He was very responsive and kept us abreast of next steps and what to expect. Same goes for Jeff at the office. We couldn't be happier with the final kitchen.
