Whole Home Rewire Services in Toronto & GTA
A whole-home rewire is one of the most important electrical upgrades a property can undergo. Outdated wiring not only limits your home’s efficiency but can also present serious safety hazards. At Langstaff & Sloan, we’ve been providing professional electrical services in Toronto and the GTA since 1991.
With decades of proven expertise, our licensed electricians handle every aspect of rewiring a whole house—from planning to installation—ensuring your system meets today’s safety codes and tomorrow’s energy demands.
Signs When a Whole House Electrical Rewire Is Necessary
Homes built more than 40 years ago often rely on wiring that no longer meets modern safety standards. Aluminum wiring, overloaded breaker panels, or outdated knob-and-tube systems increase the risk of electrical fires and frequent power disruptions.
Signs that you need an electrical rewiring for a whole-house project include:
- Flickering or dimming lights
- Frequent tripped breakers or blown fuses
- Warm or discoloured outlets
- Limited number of outlets for modern usage
- Planning for a major renovation or addition
A whole-house electrical rewire eliminates these risks while preparing your home for increased electrical loads, such as EV chargers, smart appliances, and modern HVAC systems.
The Long-Term Benefits of Electrical Rewiring a Whole House
Benefits include:
- Reduced risk of electrical fires
- Support for modern appliances and EV charging
- Lower energy waste through efficient wiring
- Increased property value
- Peace of mind with a safe, reliable system
Investing in rewiring a whole house provides more than immediate safety improvements. It adds long-term value, improves resale appeal, and reduces the likelihood of insurance issues related to outdated wiring.
What a Whole House Electrical Upgrade Includes
A whole-house electrical upgrade is more than just replacing wires. It’s a full system improvement designed for long-term safety and efficiency.
Key upgrades often include:
- Replacement of outdated wiring with copper wiring
- Installation of new outlets and switches to meet modern layouts
- Upgraded service panels to handle higher electrical demand
- Integration of safety devices such as AFCI and GFCI breakers
- Improved grounding systems for surge protection
We ensure that for every home rewire, our licensed electrician follows strict safety codes while minimizing disruption to your household during the process.
Whole House Electrical Wiring Cost
Many homeowners ask about the whole-house electrical wiring cost. While no two homes are the same, costs depend on factors like square footage, accessibility of wiring, and the complexity of upgrades needed. For example, a small bungalow may be less complex than a multi-story home with finished walls.
At Langstaff & Sloan, we provide a detailed house rewiring estimate upfront so you know exactly what to expect—no hidden fees.
