Basement & renovation wiring in Markham: what to expect
Renovations in Markham usually mean older walls with surprises behind them. We plan the electrical for the finished space — circuits, lighting, data and alarms — and book ESA inspections so drywall isn't held up.
Legal secondary units are a big part of renovation work in Markham. A second unit needs its own considerations: interconnected smoke and CO alarms, separate lighting and receptacle circuits, often a sub-panel, and a load calculation to confirm the service can carry two households.
We work directly for homeowners or alongside your general contractor, with a clear rough-in window so other trades keep moving.
