Electrical Wiring & Rewiring in Mississauga & the GTA
New circuits, renovation wiring, and replacing the old wiring insurers ask about. Permit and inspection on every job.
Renovations
Kitchens need more dedicated circuits than most people expect — the fridge, the microwave, the dishwasher and the counter outlets each have their own rules. Basements usually need new circuits, lighting and smoke alarms, and a legal second unit has its own requirements on top. We wire to what the inspector will look for, so the rough-in passes the first time.
New circuits
A circuit for a home office, a garage workshop, a freezer, a window air conditioner, an outdoor outlet. If the panel has no room left, we will tell you whether you need more slots or more power.
Old wiring
Knob-and-tube wiring — in many houses built before the 1950s — and aluminum branch wiring from the late 1960s and 1970s are the two that come up when you buy a house or renew your insurance. Some insurers will not cover a house that still has them. We can replace them, in stages if that suits you, and give you the ESA certificate the insurer asks for.
The permit
New wiring is notified to the Electrical Safety Authority. On a renovation the inspector checks the rough-in before the walls are closed, and again at the end. We book both.
