How long does a whole-home rewire take for a two-storey in Brentwood?

A whole-home rewire for a two-storey home in Brentwood typically takes 7 to 12 working days on-site, though the total project timeline from start to final inspection is usually 2 to 4 weeks when you factor in permit processing, inspection scheduling, and any drywall repair. Brentwood homes were predominantly built in the 1960s and 1970s, and their construction style directly affects the timeline.

The work breaks down into several phases. Rough-in is the most labour-intensive phase, taking 4 to 7 days for a typical Brentwood two-storey. During this phase, the electrician opens walls where necessary, removes old wiring, and runs all new NMD90 copper circuits from the new panel location to every outlet, switch, and fixture box throughout the house. In a two-storey home, running wire between floors is one of the more time-consuming tasks — the electrician needs to drill through top plates, fish wire through wall cavities, and navigate around existing plumbing and HVAC runs. Brentwood homes from this era typically have 1,400 to 2,000 square feet across two floors, which means 20 to 35 circuits in a modern rewire compared to the 8 to 15 circuits the home likely has now.

After rough-in, a Safety Codes Officer inspects the exposed wiring before any walls are closed. Scheduling this inspection typically takes 3 to 10 business days after your electrician calls it in to the City of Calgary. This is a critical checkpoint — the inspector verifies wire routing, box fill calculations, proper grounding and bonding, AFCI protection on required circuits, and compliance with the Canadian Electrical Code as adopted by Alberta. If corrections are needed, your electrician addresses them and schedules a re-inspection, which adds time.

Once the rough-in passes inspection, drywall repair can proceed — patching the openings made during the rewire, taping, mudding, sanding, and painting. If you are handling drywall repair separately, this adds 3 to 5 days depending on the scope. Some homeowners coordinate the rewire with a renovation to avoid double drywall work. After drywall is complete, the electrician returns for trim-out — installing outlets, switches, cover plates, and light fixtures — which takes 1 to 2 days. A final inspection may be required depending on the scope.

Calgary's chinook climate is one reason Brentwood homes are prime candidates for rewiring. After 50 to 60 years of rapid temperature swings, original wiring insulation becomes brittle and connection points loosen from repeated thermal cycling. Many Brentwood homes also have aluminum branch circuit wiring from the 1965-1975 era, which adds complexity and cost to the project if a full copper rewire is chosen over connector remediation.

Scheduling strategy matters in Calgary. Booking your rewire during the winter months (November through February) often means faster electrician availability since outdoor projects are paused. The rewire itself is indoor work and can proceed regardless of weather. However, if your home needs a service entrance upgrade or meter base work — which requires ENMAX coordination — plan for an additional 2 to 4 weeks for ENMAX scheduling on top of the electrical work timeline.

A Brentwood two-storey rewire typically costs $15,000 to $26,000 including a 200-amp panel upgrade, all new circuits, devices, and permits. Get quotes from at least three licensed electricians, verify WCB Alberta coverage, and confirm the timeline expectations with each contractor before committing.
