Our contractor arranged to have Campoli upgrade our 100A panel to 200A and disconnect the remaining Knob and Tube wiring. They arranged for the permits, arrived on time, disconnected the panel, removed it, removed the stack, replaced the new stack, installed the new panel, and was able to have our house up and running with power by day's end. We are left with no power where the circuits fed by K&T wiring but we expected that. They didn't clean up the basement, but I was happy to finish it up.
