Recurring Electrical Contractors Challenges We Solve

Choosing the right contractor can feel confusing when every quote looks different. Here is what homeowners ask us to sort out before they commit.

🆔

Not Sure If Contractor Is Licensed

Many homeowners cannot tell the difference between a certified electrician and a licensed contractor business, which are not the same credential. We provide our ECRA/ESA license number upfront and explain exactly what it covers.

💵

Wildly Different Quotes for Same Job

A wide spread between quotes usually means one contractor priced from an actual inspection and another guessed over the phone. We assess the panel and wiring in person before giving any number.

📋

Worried About Unpermitted Electrical Work

Skipped permits create real problems during a home sale or insurance claim, and the risk falls entirely on the homeowner, not the contractor who skipped it. We file every required ESA notification as a standard part of the job.

🏚️

Old House Has Knob-and-Tube or Aluminum Wiring

Older wiring types require different handling than modern copper, and a contractor unfamiliar with them can misdiagnose the real scope of work. We recognize these systems on sight and use the connection methods rated for them.

🛡️

Contractor Won't Provide Proof of Insurance

A contractor unwilling to produce WSIB coverage or liability insurance on request is shifting real financial risk onto the homeowner. We share current certificates before any technician steps onto the property.

⚡

Panel Can't Handle New Circuit

Adding a new circuit or appliance to an already maxed-out panel can cause nuisance tripping or overheating. We check panel capacity before quoting any work that adds electrical load.

🧾

Unclear What's Included in the Quote

A vague quote leaves too much room for surprise charges once work is underway. We provide a written scope so homeowners know exactly what is covered before any work starts.

🏠

Need a Contractor With Real Residential Experience

A contractor whose recent work is mostly commercial may be less familiar with the quirks of an older house. We ask homeowners about their specific concerns upfront so the right technician handles the job.

🔄

Hesitant to Hire After Bad Experience

A previous contractor who cut corners on permits or insurance can make homeowners cautious about hiring anyone new. We walk through our credentials and process clearly before asking for any commitment.

Customer Reviews

Read Before You Book

Daniel R.

Actually showed me the license number

I asked three contractors for their ECRA/ESA license before hiring anyone. Markham Electrical Services was the only one who had it ready without me having to ask twice. That alone told me a lot about how they run things.

Priya M.

Caught the aluminum wiring right away

Our house is from the 1970s and the technician spotted the aluminum branch wiring the moment he opened the panel. He explained exactly why it needed different connectors and handled it properly instead of treating it like copper.

Marcus T.

Great work, quote went up slightly

The panel was in worse shape than expected once they opened it up, so the final price came in a bit higher than the initial estimate. They explained why before doing any extra work, so I never felt blindsided.

Wendy S.

Permit handled without me asking

I did not even have to bring up the ESA permit, the crew from Markham Electrical Services just included it as part of the job from the start. Having the inspection certificate on file gave us real peace of mind before listing the house.

Anthony K.

Insurance proof provided instantly

I asked Markham Electrical Services to see proof of liability insurance and WSIB coverage before letting anyone start, and it was emailed to me within minutes. That level of transparency is rare and it made the whole decision much easier.

Grace L.

Honest about what our old panel needed

The technician from Markham Electrical Services walked me through exactly why our 60-amp panel could not support the new circuit I wanted before recommending an upgrade. No pressure, just a clear explanation of the actual risk.

How It Works

Priced Before It Starts, Tested Before We Go

Electrician checking a completed panel installation

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.
