Residential Wiring & Rewiring

Many older Calgary homes — particularly in established neighbourhoods like Inglewood, Ramsay, Bridgeland, and Mount Royal — still have knob-and-tube or aluminum branch wiring that insurance companies increasingly refuse to cover. A full rewire replaces aging wiring with modern NMD90 copper throughout, adds grounded outlets, and brings your entire electrical system up to current Canadian Electrical Code as adopted by the Alberta Building Code. All electrical work in Alberta requires a permit from your local Safety Codes Officer.

Calgary's extreme temperature swings — from -30°C winter cold snaps to sudden chinook-driven thaws — put unique stress on wiring insulation, particularly in unheated attic spaces and exterior walls. Thermal cycling causes old rubber and cloth insulation to crack and deteriorate far faster than in milder climates. A professional rewire eliminates these hidden hazards and ensures your home can safely handle modern electrical loads including heat pumps, garage heaters, and block heater circuits that Calgary homeowners rely on through Alberta winters.
