From a single flagged receptacle to a full panel review, these are the deficiency notices property owners bring to us most.
A deficiency notice lists every part of the electrical installation that failed to meet code, and it will not close on its own. We review the notice line by line and correct each listed item so the property can pass re-inspection.
Reversed polarity means a receptacle's hot and neutral wires are swapped, which still powers equipment but creates a shock risk on certain devices. We correct the wiring and verify polarity on every affected receptacle.
A missing or degraded bond leaves metal enclosures without a safe path for fault current, which can energize the surface during a fault. We reconnect or run new bonding conductors and verify continuity with a meter.
Washrooms, exterior receptacles, and areas near plumbing fixtures often lack the GFCI coverage current code now requires, even on buildings that were compliant when originally wired. We install GFCI receptacles or breakers to close the gap.
A breaker rated too high for its conductor allows the wire to overheat well before the breaker ever trips, creating a hidden fire risk. We replace the breaker with one correctly matched to the connected conductor.
Work completed without a permit was never inspected, which means it can carry deficiencies that predate current ownership entirely. We assess the unpermitted work, correct any code violations, and document everything for the record.
A junction box packed with more conductors than it is rated for creates a heat and arc risk hidden behind a closed cover. We reorganize the connections into a properly sized box and secure it to code.
Insurers increasingly ask commercial policyholders to confirm no open ESA notices exist before renewing a policy. We complete the corrections and coordinate directly with the ESA so the renewal is not held up.
A notice can list several items at once, and not every deficiency carries the same level of risk or urgency. We prioritize life-and-property-safety findings first and walk through the rest in plain language.
We had an open deficiency notice that our incoming tenant's lawyer flagged during due diligence. Markham Electrical Services came out within days, corrected everything on the list, and coordinated the re-inspection so we closed the lease on time.
The technician walked through the ESA notice line by line before touching anything and told us exactly why each deficiency mattered. No confusing jargon, just a clear plan and a fair price for the work.
Our notice had more panel deficiencies than expected so it took a follow-up visit to finish everything properly. The team explained why upfront and did not charge extra for the return trip, which I appreciated.
The electrician found a bonding gap in our panel room that was not even on the original notice and fixed it as part of the same visit. Markham Electrical Services clearly knows what to look for beyond just the checklist.
We needed several GFCI upgrades corrected before our insurance renewal. Markham Electrical Services had the whole job done in one afternoon and the re-inspection was booked before the crew even left the building.
I was worried the quote would balloon once they got into the panel, but the price stayed exactly what we were told upfront. The whole process felt honest from the first call to the final re-inspection.

You get a real arrival window rather than a whole day, and a call if anything moves. Emergency work is dispatched rather than scheduled.
The written figure includes permit and inspection, and the exclusions are set out as clearly as the inclusions, which is where most disputes start.
Work to the agreed scope with nothing added quietly. If something unforeseen appears, you decide what happens next, not us.
Tested under genuine load before the panel closes, then certified. Our labour carries two years, the equipment its manufacturer warranty.

A board full of tandem breakers is already at its limit. Knowing that first saves buying equipment you cannot run.
