Wiring & Rewiring

Whether you're building new or renovating, we provide complete electrical wiring services that meet or exceed the Ontario Electrical Safety Code.

Wiring & Rewiring — professional electrical work in Toronto & the GTA

Scope of work

  • New construction rough-in wiring
  • Renovation and addition wiring
  • Old wiring assessment and replacement
  • Dedicated circuits for heavy loads
  • Structured wiring for data and phone
  • Permit acquisition and ESA inspection

Good wiring is the backbone of a safe home. We use 14/2 and 12/2 NMD90 copper wire with proper ampacity for each circuit. For kitchens and bathrooms, we install dedicated 20A circuits as required by code. All junction boxes are accessible, connections are made with approved wire connectors, and every circuit is labeled in the panel. We coordinate with other trades during renovations and handle ESA permits.

Wiring & Rewiring FAQs

How much does it cost to rewire a house in Ontario?

A full rewire of a typical 1,500–2,000 sq ft GTA home runs $8,000–$15,000 depending on access, finishes, and whether the panel needs upgrading at the same time. Partial rewires (one floor or a renovation area) cost considerably less. We provide fixed written quotes after a walkthrough.

Can you rewire a house without removing all the drywall?

In most cases, yes. Experienced electricians fish new cable through wall cavities, attics, and basements with strategic small openings rather than gutting walls. Plaster-and-lath homes need extra care, but full demolition is rarely required for a rewire.

Do I need to rewire my older home before selling it?

Not necessarily, but homes with knob-and-tube or aluminum wiring often face insurance and financing hurdles that complicate a sale. An electrical inspection report and targeted upgrades — panel, grounding, GFCI protection — usually deliver the best return before listing.
