Call (416) 828-6976Serving Markham
Markham homeowners increasingly ask us for smart lighting and EV charger installations alongside standard repairs, while local businesses rely on us for ongoing commercial electrical maintenance. Our licensed electricians serve Markham with the same upfront pricing and code-compliant work as everywhere else in the GTA.
In Unionville and Berczy Village, where many homes were built from the 1990s onward, we see more EV charger installations, smart dimmer upgrades, and potlight retrofits than panel replacements. Cornell’s newer new-urbanist homes bring similar requests alongside the occasional builder-grade panel that needs upsizing for a renovation. Around Milliken and Markham’s tech and office corridors, commercial electrical maintenance and lighting retrofits are our most common calls.
We regularly work in:Unionville,Milliken,Cornell,Berczy Village, and the rest of Markham.

Why It Matters
A breaker that trips once might just mean too many appliances on one circuit. A breaker that trips repeatedly, an outlet that’s warm to the touch, a burning smell near the panel, or lights that dim when the fridge kicks on are different: those are symptoms of a fault that will keep coming back until someone traces it to the source, whether that’s a loose connection, an overloaded circuit, or aging wiring. Resetting the breaker fixes the symptom for an afternoon; it doesn’t fix the problem. Our troubleshooting calls are built around finding the actual root cause on-site, often with a multimeter and a systematic circuit trace rather than guesswork, so you’re not paying for the same call-out twice.
How Electrical Troubleshooting Works
- 1
Same-day diagnostic call
We schedule you in quickly, including emergency same-day response for urgent issues like power loss, sparking outlets, or burning smells.
- 2
On-site testing & diagnosis
We trace the circuit and test the panel, wiring, and devices involved to identify the actual root cause, not just the symptom.
- 3
Upfront repair quote
Before any repair work starts, we explain what we found and give you a clear price for the fix.
- 4
Repair & verification
We complete the repair and test the circuit under normal load to confirm the issue is resolved before we leave.
What Affects the Cost
Diagnostic complexity is the main driver: a single dead outlet is a quick trace, while an intermittent fault across multiple circuits takes longer to isolate. Beyond that, cost depends on whether parts need replacing, whether the fix is a repair or points to a larger issue like a panel replacement, and whether the call is during standard hours or after-hours emergency service.
