Typical Electrical Upgrades Problems We Fix

Homes outgrow their electrical service in different ways. These are the situations that bring homeowners to us most.

⚡

Breakers Trip When Running Multiple Appliances

Frequent trips during normal daily use usually mean the panel is pulling more load than it was designed for. We assess actual usage and size a new panel to match it.

🧯

Home Still Has a Fuse Box

Fuse boxes were common before the 1960s and often struggle to meet modern insurance and safety standards. We convert to a modern breaker panel sized for today's electrical demands.

🔋

EV Charger Overloads the Panel

A single EV charger can draw as much as 40 amps, which older panels were never built to handle alongside everything else. We upgrade capacity so the charger runs without straining the rest of the home.

🔌

Panel Rated Below 100 Amps

A panel under 100 amps is often undersized for a home with modern appliances, electronics, and HVAC equipment. We evaluate current and future load before recommending the right amperage.

💡

Whole House Lights Flicker Together

Flickering across multiple rooms at once, rather than a single fixture, usually points to a panel-level issue rather than a localized fault. We trace it back to the panel and correct the underlying capacity problem.

📋

Insurance Requires a Panel Upgrade

Some insurers now require a modern panel as a condition of coverage, particularly for homes built before 1985. We complete the upgrade and provide documentation your insurer can rely on.

❓

Not Sure If Rewiring Is Also Needed

Homeowners often assume a full rewire is required simply because the panel looks old. We assess the actual wiring condition first and recommend only the work the home genuinely needs.

💰

Worried the Cheapest Quote Skips Steps

A quote well below others for the same scope often means the permit, inspection, or proper grounding steps are being cut. We include every required step in our quoted price from the start.

🏠

Panel Upgrade Needed Before Listing a Home

An outdated panel or fuse box can reduce buyer confidence and complicate a sale. We complete permitted upgrades that hold up under a buyer's inspection.

Customer Reviews

Read Before You Book

Steven K.

Sized it right for our EV charger

We wanted a charger installed next year and the technician from Markham Electrical Services sized the new panel for that future load instead of just meeting today's needs. Saved us from paying for a second upgrade down the road.

Melissa D.

Explained why our quote was higher than another

Another company quoted less but when I asked about the permit they went quiet. Markham Electrical Services broke down exactly what was included and it made the comparison easy. Went with them and no regrets.

Anthony R.

Good work, meter base added to the cost

The quote went up once they found our meter base was corroded, but they explained why before doing anything extra. Panel upgrade is done and passed inspection with no issues.

Grace P.

Didn't need the rewiring we thought we did

I assumed our whole house needed rewiring because the panel looked so old. Turned out the wiring itself was fine and we just needed the panel swapped. Saved thousands compared to what I was bracing for.

Derek M.

Handled the utility coordination for us

Our service entrance needed work too so there was utility involvement, but Markham Electrical Services coordinated the whole thing. I didn't have to make a single call myself.

Nicole T.

Whole house feels different now

No more tripping breakers when the AC and dryer run at the same time. The upgrade took about six hours and the panel is labeled clearly, which our old one never was.

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.

Is There Room in the Panel?

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