Homeowners say a hearty ``Welcome!'' when Luis Bosch shows up for the weekend. That's because Bosch is there to make things whole. The Cordoba, Spain-born and Miami-based contractor pulls out his tools and all the stops to assist the homeowners with a weekend project that has long been in the planning stages but never got off the ground. Over the course of two hardworking, chaotic, sweat-filled days, Bosch transforms the homeowners into weekend warriors and, come Sunday evening, the payoff is a stunning renovation.
