Frequently Asked Questions About Electrical Contractor Markham in Oshawa
Electrical project costs in Markham can range from approximately $1,000 for smaller jobs like pot light installations or smart thermostat setups, up to $22,000 or more for major projects such as full panel upgrades, whole-home rewiring, or complex generator installations. We provide transparent quotes after assessing your specific needs.
Yes, most significant electrical work in Markham requires an ECRA/ESA permit to ensure safety and compliance with the Ontario Electrical Safety Code. Renohouse.ca handles all necessary permit applications on your behalf, ensuring your project is fully compliant.
At Renohouse.ca, we pride ourselves on efficiency. For many projects, we can provide a detailed quote within 1 hour of receiving photos and project details, allowing you to quickly plan your electrical upgrades.
Absolutely. All Renohouse.ca electrical contractors are fully licensed by the Electrical Safety Authority (ESA) and carry comprehensive insurance, providing you with peace of mind and protection for your property.
Yes, we specialize in EV charger installations for all types of homes, including older properties in areas like Unionville. We'll assess your current electrical panel and infrastructure to ensure a safe and efficient installation, including any necessary upgrades.
Renohouse.ca serves all communities within Markham, including Unionville, Cornell, Berczy, Angus Glen, and throughout the postal codes L3P to L6E. We cover the entire GTA from our Etobicoke base.
Upgrading your electrical panel increases your home's electrical capacity, prevents frequent breaker trips, enhances safety by reducing fire hazards, and is often necessary for installing new high-demand appliances like EV chargers or central air conditioning. It also improves your home's resale value.
Outdoor outlets require weatherproof GFCI-protected receptacles installed in code-compliant boxes. We run dedicated circuits from your panel to strategic outdoor locations — patios, garages, sheds, and garden areas. All installations meet ESA requirements and include proper grounding for safety.
A panel upgrade (typically 100A to 200A) involves replacing the main breaker panel, upgrading the service entrance cable, and potentially upgrading the meter base. The process takes 4–8 hours and requires a temporary power shutoff. We coordinate with your local utility and ensure ESA inspection approval.
Hot tubs typically require a dedicated 240V/50A circuit with GFCI protection. We run the wiring from your panel to the hot tub location, install a disconnect switch within sight of the tub (code requirement), and ensure everything passes ESA inspection. Planning ahead during deck construction saves on installation costs.
