Frequent Top-Rated Commercial Electrician Troubles We Correct

From tripped panels to failed inspections, these are the issues property owners and business managers bring to us most.

⚡

Panel Trips Under Normal Business Load

A commercial panel running near its rated capacity trips whenever multiple pieces of equipment draw power at once, often during peak business hours. We assess the actual load and correct undersized circuits so the panel can handle normal operations without interruption.

📋

Not Sure If a Contractor Is Licensed

Business owners often cannot verify whether a contractor holds the Master Electrician license commercial work actually requires. We provide proof of ECRA/ESA licensing and WSIB coverage upfront, before any contract gets signed.

⚠️

Previous Electrical Work Was Never Permitted

Unpermitted commercial work can void insurance coverage and stall an inspection when a buyer, lender, or landlord requests documentation. We pull the proper ESA permit on every job and provide full inspection records.

🍳

Kitchen Equipment Trips Breakers During Service

Restaurant kitchens draw significant dedicated load for refrigeration, cooking equipment, and ventilation, and an undersized circuit shows up as a tripped breaker mid-service. We size circuits to the kitchen's actual equipment load before problems reach the dinner rush.

🌙

Power Outage Overnight With No Emergency Response

A sudden outage or sparking equipment outside business hours can mean spoiled inventory or a missed opening. We offer after-hours emergency response to isolate the hazard and get a business back online quickly.

🏢

Tenant Improvement Needs New Circuits Fast

A retail buildout or office renovation often needs new circuits and updated lighting before a tenant can move in on schedule. We coordinate the electrical scope around the broader construction timeline to keep the project moving.

🏗️

Multi-Tenant Building Needs Coordinated Shutdown

Work on shared infrastructure like a main panel affects every tenant in a building at once, and an uncoordinated shutdown creates unnecessary disruption. We plan phased shutdown windows with property management so no single tenant loses power longer than necessary.

📁

Lease Requires Electrical Documentation We Don't Have

Commercial leases often require current electrical inspection and permit records that a property owner cannot easily produce. We leave updated panel schedules and full documentation after every job for exactly this purpose.

🔍

Cheap Quote Skipped the Permit and Insurance

A noticeably low commercial quote often means the ESA permit was skipped or the contractor lacks proper liability coverage. We price every job to include the permit, inspection, and full insurance from the start.

Customer Reviews

Read Before You Book

Facilities Manager Wendy T.

Handled our whole office relocation wiring

We needed new circuits and lighting across three floors before our tenants moved in. Markham Electrical Services coordinated the shutdown windows so no other tenant lost power and finished ahead of schedule.

Marcus H.

Saved our restaurant opening

Our kitchen equipment kept tripping breakers two days before opening. They came out same day, found the load issue, and had it fixed before our first dinner service. Genuinely saved us.

Priya D.

Good work, quote took a bit to finalize

The walkthrough and written estimate process was thorough but took a day longer than I expected to get in writing. Once the work started it went smoothly and passed inspection right away.

Owner Daniel R.

Actually checked our insurance requirements

The technician from Markham Electrical Services asked about our lease requirements before starting and made sure we had the documentation our landlord wanted. Nobody else I called even mentioned that.

Gordon P.

Master electrician on site, not just a helper

I specifically asked if a Master Electrician would be overseeing our panel upgrade and they confirmed it without hesitation. That mattered to us given how much equipment runs through our shop.

Isabelle K.

Weekend scheduling made the difference

We couldn't afford to close during the week so Markham Electrical Services scheduled our tenant fit-out wiring over a weekend instead. Clean work, fully documented, and we didn't lose a single business day.

How It Works

Priced Before It Starts, Tested Before We Go

Book a Time

You get a real arrival window rather than a whole day, and a call if anything moves. Emergency work is dispatched rather than scheduled.

Assessment and Quote

The written figure includes permit and inspection, and the exclusions are set out as clearly as the inclusions, which is where most disputes start.

Installation

Work to the agreed scope with nothing added quietly. If something unforeseen appears, you decide what happens next, not us.

Verified

Tested under genuine load before the panel closes, then certified. Our labour carries two years, the equipment its manufacturer warranty.

New Loads, Old Services

A Full Panel Blocks Everything You Add Next

Tandem breakers filling a board mean the service is already at its limit. The replacement allows for what is planned as well as what is present.
