Wiring & Rewiring Electrician in Dundas

The cost of knob and tube rewiring in Dundas depends on the size of your home, how much of the original wiring is still active and whether a panel upgrade is needed at the same time. A typical Dundas home with partial knob and tube rewiring starts in the range of $8,000–$12,000; a full house rewiring in a larger home can be $15,000 or more. We give you a flat-rate written quote after a site assessment — the price you approve is the price you pay, with no hidden costs. Many Dundas homeowners find that the insurance savings from removing knob and tube wiring recover a significant portion of the cost within a few years.

Yes, in most cases. Our rewiring electricians work room by room so that the majority of your home stays powered throughout the job. Each area is isolated, rewired and reconnected before we move to the next room. You will have planned periods without power in specific areas, but you are never without electricity in the whole house at once. A full house rewiring in Dundas typically takes 3 to 5 days. We walk you through the schedule before we start so there are no surprises.

Yes. In Ontario, any significant wiring or rewiring work — including knob and tube rewiring, aluminum wiring replacement, new circuits and panel upgrades — requires an ESA permit and inspection. We handle all of this as part of our wiring and rewiring service in Dundas. You do not need to apply for anything or coordinate with ESA yourself. After the inspection passes, we provide you with the written ESA documentation you will need for your insurance company, mortgage lender or real estate agent. Wiring work done without a permit can void your home insurance and create serious problems at resale.

Aluminum wiring is a recognized fire hazard. It expands and contracts more than copper with changes in temperature, which causes connections at outlets, switches and the panel to loosen over time. Loose aluminum connections arc and generate heat inside the wall — often with no visible warning. ESA and most Ontario insurers consider aluminum wiring a high-risk condition. Full aluminum wiring replacement with copper is the only permanent solution. Some homeowners choose CO/ALR connections as a temporary measure, but this does not address the wiring inside the walls. If your Dundas home was built between 1965 and 1975, there is a high likelihood it has aluminum wiring — our electricians can assess it and give you a clear recommendation.

Home rewiring always requires some access to walls, ceilings and floors to run new electrical wiring — there is no way around this. The amount of damage depends on the layout of your home and the access points available. Our rewiring electricians in Dundas plan entry points carefully to minimize the number of openings and use existing penetrations wherever possible. We patch all openings before we leave, though finish painting is typically left to you or your painter. The alternative — leaving knob and tube or aluminum wiring in place — carries significantly higher risk than the inconvenience of a few patched walls.

This is one of the most common reasons Dundas homeowners call us for knob and tube rewiring. Most Ontario insurers now give a deadline — typically 30 to 90 days — to have the knob and tube wiring removed or they will cancel the policy. Call us as soon as you receive that letter. We assess the scope of the rewiring, give you a flat-rate quote and schedule the job quickly. After the ESA inspection passes, we provide written documentation confirming the knob and tube wiring has been replaced with modern copper wiring — exactly what your insurer needs to reinstate or continue your policy. Do not wait until the deadline; electrical contractors in the Dundas area book up during peak season.
