Running wiring through finished walls is one of the more skilled parts of residential electrical work, since it involves getting new wires from point A to point B without unnecessarily damaging your walls. Here is how licensed electricians actually approach it, from the team at EZSMART, serving Toronto and the GTA.
Even skilled electricians typically need to cut some access holes in walls to run wiring through finished spaces. The goal is minimizing these and placing them where drywall repair is straightforward, not eliminating them entirely, which is generally not realistic for anything beyond very short runs. Most electricians can advise you on drywall repair or coordinate with a drywall contractor if extensive patching is needed.
Beyond the safety and code compliance issues with DIY electrical work, running wiring through finished walls specifically requires experience knowing where obstacles typically are, how to work around insulation, and how to route wires without damaging existing wiring or plumbing behind the wall. This is a skill electricians develop over years, and attempting it without that experience often results in more wall damage, not less. Any new wiring work should be performed by a licensed electrician and permitted through the Electrical Safety Authority.
Will my electrician need to cut a lot of holes in my walls?
The number of holes depends on the wiring route and wall structure, but a skilled electrician minimizes them. Expect some, but not extensive damage for typical projects.
Does my electrician patch the drywall after wiring is complete?
This varies by contractor. Some include basic patching, others coordinate with a drywall contractor, and some leave patching to the homeowner. Confirm this when getting a quote.
Are there wireless options to avoid running new wires?
Some smart home devices reduce the need for new wiring in specific applications, though hardwired power for outlets and fixtures still requires proper wiring.
