Knob & tube replacement in Oshawa: what to expect
Oshawa still has houses running on knob and tube — mostly pre-1950 homes. Many insurers now decline or surcharge them, and the wiring was never designed for modern loads.
We rewire room by room while you live there: home-run circuits from the basement and attic, small planned openings elsewhere, power restored to occupied rooms at the end of each day.
When it's done you get the ESA Certificate of Acceptance and a completion letter for your insurer. Pairing the rewire with a 200 A upgrade saves a second permit and a second visit from Oshawa Power.
