Electrical Wiring, Rewiring & Rough-In in Richmond Hill

Wiring is the part of an electrical system nobody sees once the walls are closed — which is exactly why it needs to be done right. We handle new circuits, rewiring, renovation wiring and rough-in work for residential and commercial projects.

Renovations are a big part of the work we do in Richmond Hill. Basement finishes, kitchen remodels, bathroom updates and additions all need wiring planned before drywall goes up. We work with homeowners and contractors to rough in outlets, lighting, switches and dedicated appliance circuits at the right stage of the project.

In older homes, we replace outdated or damaged wiring and add circuits where the original layout no longer fits how the home is used. In commercial spaces, we run wiring and conduit for tenant improvements, office layouts and retail fit-outs.

We keep wiring organized, secured and clearly labelled at the panel so future work is simpler and safer.

Frequently Asked Questions

When should an electrician come in on a renovation?

Early — ideally during planning and again before insulation and drywall. That's when rough-in wiring is installed.

Do you work with general contractors?

Yes. We regularly coordinate with contractors and other trades on renovation and commercial projects.

Does my older home need rewiring?

Not necessarily. We assess the condition of the wiring and recommend rewiring only where it's needed.

Can you add a circuit for a specific appliance?

Yes — for ranges, dryers, freezers, workshop equipment, hot tubs and similar loads.
