Rewiring
in Oakville

If your home was built before 1975, there is a good chance it has outdated wiring that no longer meets Ontario safety standards. Knob-and-tube wiring (common in homes built before 1950) and aluminum wiring (common in homes built between 1965-1975) are the two most common types that require replacement. Insurance companies increasingly refuse coverage or charge higher premiums for homes with these wiring types. Beyond insurance, outdated wiring is a genuine fire hazard.

We specialize in knob-and-tube wiring removal and replacement, aluminum wiring remediation (pigtailing or full replacement), outdated copper rewiring for homes that need more circuits or higher capacity, circuit additions for renovations, home offices, or new appliances, and full home rewires for major renovations or insurance requirements. Every rewiring project includes ESA permit, inspection, and certificate.

Step 1: Full electrical assessment of your current wiring. We identify all areas that need attention. Step 2: Detailed written quote with scope of work, timeline, and pricing. Step 3: Professional rewiring by our licensed electricians with minimal disruption to your home. Step 4: ESA inspection and certificate of compliance. Step 5: We patch and repair any necessary drywall openings (or coordinate with your contractor).

Many Ontario insurance companies now require knob-and-tube and aluminum wiring to be replaced as a condition of coverage. If you are buying a home with older wiring, your home inspector will flag it and your insurer may require replacement before closing. Getting ahead of this saves money and stress. We provide documentation that satisfies insurance requirements.

A homeowner in Brampton's Peel Village neighbourhood purchased a 1952 bungalow that still had active knob-and-tube wiring throughout. Their insurance company gave them 90 days to replace it or lose coverage. We completed a full rewire in five days - removing all the K&T, installing modern NMD90 copper throughout, and providing the ESA certificate the insurer required. The homeowner's premium dropped significantly the following renewal. In Mississauga's Lakeview area, a buyer discovered during their home inspection that the house had aluminum wiring from a 1971 build. Rather than do a full rewire, we assessed which circuits posed the highest risk and performed pigtailing on all device connections throughout the home - a two-day job that brought the insurance company's concern to zero. A Brampton homeowner in the Madoc Drive area was finishing an addition and needed the entire new section wired from scratch. The main home was already on copper, so we matched the existing circuit layout, added four new circuits from the panel, and completed both the rough-in and the final before the drywall crew arrived. A Georgetown homeowner had a 1969 ranch-style home where the previous owner had done unlicensed wiring in the basement. The work was not to code and failed a safety inspection. We removed the unpermitted wiring, assessed what could be kept, and re-ran everything in the basement to ESA standard with a clean inspection.

Between 1965 and 1975, aluminum wiring was used in tens of thousands of GTA homes as a cost-saving alternative to copper. The problem was discovered over time: aluminum expands and contracts more than copper with temperature changes, which causes connections to loosen at outlets, switches, and panels. Loose connections create heat. Heat creates fire risk. That does not mean aluminum wiring must always be fully replaced. There are two approaches we evaluate for each home. Pigtailing is the less invasive option. A licensed electrician installs short copper wire segments at every device connection (outlet, switch, fixture) using CO/ALR-rated connectors approved for aluminum-to-copper connections. The aluminum wiring itself stays in the walls. Pigtailing is faster and less expensive than full replacement and is accepted by most Ontario insurance companies when done correctly. Full replacement means running new copper wiring throughout the home and removing the aluminum. This is required when the aluminum wiring is in poor condition, when the home is undergoing a major renovation that opens the walls anyway, or when the insurance company specifically requires it. Both approaches require an ESA permit and inspection. During your $49 assessment, we identify exactly which circuits have aluminum wiring, assess the condition of the connections, and recommend the right approach for your home and your insurer.
