Stone, brick and plaster
Rewiring a framed house is mostly a matter of fishing cable through hollow walls. In the solid stone and brick houses of Galt, Preston and Hespeler there is less room to work, and plaster is less forgiving than drywall. Routes are planned through floors, attics and closets, and you are shown beforehand where access is needed.

Questions about old wiring replacement
Does all knob-and-tube have to come out?
Insurers usually want it all replaced. From a safety point of view, circuits that are still live are the priority.
Can it be done in stages?
Yes. Many people rewire one floor or one area at a time.
Will I get paperwork for my insurance company?
Yes. Once the work passes its ESA inspection, you receive documentation you can pass on.
