How much does it cost to rewire an older home in Moncton during a renovation?

Rewiring an older home in Moncton typically costs $8,000-$15,000 for a standard 1,200-1,500 sq ft home, or approximately $5-$10 per square foot. The final cost depends on the home's size, accessibility of existing wiring, panel upgrade requirements, and how much drywall repair is needed afterward.

Scope and Pricing Breakdown

A complete rewire involves replacing all electrical wiring from the panel to every outlet, switch, and fixture in the home. In Moncton's older housing stock — much of which dates to the 1940s-1970s — you're often dealing with outdated cloth-wrapped wiring, undersized circuits, and electrical panels that don't meet current code requirements. The electrical work itself runs $6,000-$12,000, while the associated drywall patching and repainting adds another $2,000-$3,000 to the total project cost.

Most older Moncton homes need a panel upgrade as part of the rewiring process, moving from 60-amp or 100-amp service to modern 200-amp service. This upgrade costs an additional $1,500-$3,000 and requires coordination with NB Power for the meter and service connection. Homes with knob-and-tube wiring or aluminum wiring from the 1960s-1970s require complete replacement — insurance companies often refuse coverage or charge higher premiums until these outdated systems are updated.

New Brunswick Code and TSANB Requirements

All electrical work in NB must be performed by a licensed electrician and inspected by the Technical Safety Authority of New Brunswick (TSANB). This isn't optional — it's provincial law. A complete rewire requires multiple TSANB inspections: rough-in inspection after wiring is installed but before drywall goes up, and final inspection after all devices and fixtures are connected. TSANB inspection fees add $200-$400 to the project cost but ensure the work meets code and your insurance remains valid.

Modern NB electrical code requires GFCI protection in bathrooms, kitchens, laundry rooms, and exterior outlets, plus AFCI (arc-fault) protection on bedroom circuits. Older homes being rewired must meet current code standards, not the standards from when they were built. This means more circuits, more outlets per room, and dedicated circuits for major appliances — all of which increases material and labour costs but dramatically improves safety and functionality.

Renovation Timing and Access

Rewiring during a renovation is ideal timing because walls are already open, eliminating much of the drywall damage and repair costs. If you're planning a kitchen renovation, bathroom updates, or whole-home refresh, coordinate the electrical work first. Running new wiring through finished walls in an occupied home costs 30-50% more due to the additional labour for fishing wires and extensive drywall repairs afterward.

Winter Interior Work Advantage

Electrical rewiring is perfect winter renovation work in New Brunswick — it's entirely interior and unaffected by weather conditions. Many Moncton electricians have better availability during winter months when exterior construction slows down. Plan the rewiring for January through March, then tackle any exterior work (siding repairs from electrical meter upgrades) during the spring and summer construction season.

Professional Requirements and Safety

Never attempt DIY electrical work beyond simple fixture swaps on existing circuits. Rewiring involves working inside the electrical panel, running new circuits, and connecting to the main service — all of which require specialized knowledge and TSANB licensing. Improper electrical work creates fire hazards, electrocution risks, and insurance claim denials. Always verify your electrician holds current TSANB licensing and WorkSafeNB coverage before starting work.

Budget an additional 15-20% contingency for older home rewiring projects. Opening up walls often reveals other issues — outdated plumbing that should be updated simultaneously, insulation problems, or structural repairs needed before closing walls back up. Getting the electrical, plumbing, and insulation work done together while walls are open saves money compared to tackling these systems separately later.
