FAQs
When is a whole-home rewire necessary?
You should consider a complete rewire if your Cowan property is more than 40 years old, still has knob-and-tube or aluminum branch wiring, frequently trips breakers, shows signs of overheating (scorched outlets, warm switch plates), or if you are planning major renovations that will add load (HVAC upgrades, EV charger, new kitchen appliances). A rewire ensures the installation meets the latest Canadian Electrical Code, provides enough circuits for modern living, and eliminates fire and shock hazards caused by aging conductors and insulation.
How long does a typical rewire take in Cowan?
For an average 1,500–2,000 sq ft single-family home, a full rewire usually takes 5–10 working days. The timeline depends on the home’s size, construction type (finished basement, plaster vs. drywall), panel location, and whether walls and ceilings must be repaired afterward. Our team completes the demolition, wiring, and device installation first, then schedules the ESA (Electrical Safety Authority) inspection. Drywall repair and painting add another few days but can overlap with electrical work if coordinated early.
Do I need to move out while the work is being done?
Not always. We plan the project in stages to keep essential circuits (fridge, heat, internet) energized whenever possible. In most Cowan homes you can stay on site, although there will be daytime power shutdowns, dust, and limited access to some rooms. Families with young children, home-office requirements, or respiratory sensitivities may choose to relocate temporarily for comfort. We discuss your schedule during the pre-job walk-through and arrange temporary power if required.
What permits and inspections are required for a rewire in Cowan?
In Ontario, any whole-home rewire must be filed with the Electrical Safety Authority (ESA) under a Notification of Work. We submit the permit before starting, and an ESA inspector visits at the rough-in stage and again at final. If we upgrade your service (e.g., 100 A to 200 A) the utility—Hydro One or local LDC—also requires a service layout and may perform a site visit. All fees and scheduling are handled by our office, and you receive the ESA Certificate of Acceptance when the job is complete.
How much does a whole-home rewire cost?
Costs vary with square footage, number of circuits, accessibility, and finishes to be restored. In Cowan, a ballpark range is $9–$14 per square foot, so a 1,800 sq ft home might run $16,000–$25,000 for wiring alone. Adding a 200 A panel, AFCI/GFCI breakers, surge protection, data cabling, or smart-home devices will increase the price. We provide a detailed, fixed-price quotation after an on-site assessment, outlining labour, materials, permit fees, and wall/ceiling patching if we handle it.
What advantages will I see after the rewire is completed?
A new electrical system delivers multiple benefits: (1) safety—modern copper wiring, grounded circuits, and AFCI/GFCI protection reduce fire and shock risks; (2) capacity—more receptacles and dedicated circuits support high-demand appliances and future technologies like EV chargers or solar inverters; (3) reliability—fewer nuisance trips and voltage drops; (4) property value—ESA certification and updated service are strong selling features; and (5) energy efficiency—correct wire sizing and tighter connections minimize energy loss, while optional LED lighting and smart controls cut utility bills.
