Panel Upgrade Caledon — 100A to 200A Done Right
Tripping breakers, no room for new circuits, or renovating and need more capacity? Our ESA-licensed electricians assess on site and give you a flat-rate written quote for Bolton, Caledon East and all of Caledon.
Signs It's Time for an Electrical Panel Upgrade in Caledon
Many Caledon homes still run on 60A or 100A panels installed decades before EV chargers, heat pumps and finished basements were a thing. Here's how you know the panel can't keep up.
Breakers Trip When You Run Two Things
Dryer and microwave can't run together? That's a panel at capacity, not a faulty breaker. Resetting it doesn't fix the underlying load problem.
Fuse Box or Known Problem Brand
Screw-in fuses, Federal Pioneer (FPE) or Sylvania/Zinsco panels are flagged by insurers and ESA for failing to trip under fault. Many insurers won't renew until it's replaced.
No Room for New Circuits
Every slot is full and the electrician says they can't add the hot tub, EV charger or basement suite without a bigger panel. That's the most common reason we get called.
Lights Dim When Appliances Start
A flicker when the furnace, AC or well pump kicks on means the service can't deliver enough current. Over time it stresses motors and electronics throughout the house.
Why Most Caledon Homes Need a 200 Amp Panel Upgrade
A 100A service was fine for a 1980s house with a gas furnace and one TV. Add a Level 2 EV charger (40A on its own), a heat pump, an induction range and a basement apartment, and you're past the limit before anyone turns on the dryer.
A 200 amp panel upgrade gives you the capacity for all of it, plus room to grow — and it's the first thing an inspector, insurer or buyer looks at. For larger rural properties with barns, shops or outbuildings, we size for 400A where it makes sense.
What's Included in Our Electrical Panel Replacement
One flat-rate price covers the whole job — not a base price with surprises added at the end.
Load Calculation & Sizing
We calculate your actual and planned demand so the new service is sized right — 200A for most homes, 400A where needed.
Hydro One / Alectra Coordination
We book the utility disconnect and reconnect so you're not left chasing the hydro company on the day.
New Panel, Breakers & Meter Base
Quality 40-circuit panel with AFCI/GFCI breakers where code requires, plus a new meter base and mast if the old one is undersized.
Grounding & Bonding to Code
New ground rods, water bond and bonding jumpers — the part older homes almost always fail on.
ESA Permit & Inspection
We file the permit, book the inspection and hand you the ESA certificate for your insurer or your home's records.
Labelled Circuits & Walkthrough
Every breaker labelled, every circuit tested, and a walkthrough so you know what's where before we leave.
Electrical Panel Repair vs. Full Replacement
Not every panel problem needs a new panel. A single failed breaker, a loose neutral or a corroded lug can often be repaired the same day for a fraction of the cost. We'll tell you honestly which one you're looking at.
- Repair makes sense when: the panel is a modern breaker type with spare capacity and a single component has failed.
- Replacement makes sense when: it's a fuse box or recalled brand, the bus bar shows heat damage, you're out of slots, or you're adding major load.
- Either way: you get a written flat-rate quote before any work starts, and we never push a replacement you don't need.
How a Panel Upgrade Day Goes
Most residential upgrades are done in one day, with power off for 4–6 hours.

Electrical Panel Upgrade Caledon — Common Questions
What homeowners ask before replacing their panel.
How much does an electrical panel upgrade cost in Caledon?
A standard 100A to 200A upgrade typically runs $2,500–$4,500 depending on the meter base, mast and grounding work needed. Rural 400A services cost more. We give a written flat-rate quote with ESA permit included before anything starts.
How long is the power off during a panel replacement?
Usually 4–6 hours. We coordinate the utility disconnect for the morning and have you back on the same afternoon. Keep the fridge and freezer closed and you'll be fine.
Do I need a 200 amp panel to install an EV charger?
Often, yes. A Level 2 charger needs a 40–60A circuit, and most 100A panels can't spare that once the range, dryer and AC are counted. A load calculation tells us for sure — sometimes a load-management device avoids the upgrade, sometimes it doesn't.
Will my insurance company require an electrical panel replacement?
Many Ontario insurers won't cover homes with fuse boxes, 60A service, or Federal Pioneer / Zinsco panels. If you've received a letter, we can replace the panel and provide the ESA certificate they ask for.
Is an ESA permit required for a panel upgrade in Ontario?
Yes, always. Any service change must be permitted and inspected by the Electrical Safety Authority. We file it, pay it, and book the inspection as part of the job — you never have to deal with ESA yourself.
Can you upgrade the panel on a rural property with a barn or workshop?
Yes. Rural Caledon properties often need a 400A service split between the house and outbuildings, with sub-panels for the barn, shop or well pump. We size the whole system, not just the house panel.

What Caledon Homeowners Say About Their Electrical Panel Upgrade
Reviews from homeowners who replaced an old fuse box or 100A panel with us and got the capacity they needed.
Bought an EV and the dealer said our 100A panel wouldn't take a Level 2 charger. Searched "panel upgrade near me", got three quotes, and these guys were the only ones who included the ESA permit and hydro coordination in the price. 200A panel in one day, charger hooked up the next.

Our insurance sent a letter saying they wouldn't renew with the old Federal Pioneer panel. Stressful. These guys explained exactly why it was a problem, replaced it with a new 200A panel and emailed the ESA certificate to my broker the same week. Renewal went through, no fuss.

Century home in Caledon East, still on a fuse box. Breakers tripped if the dryer and kettle ran together. Did a full electrical panel upgrade with new grounding and a proper meter base. The install crew was tidy, labelled every circuit, and walked me through the whole thing before they left.

Rural property near Palgrave with a barn and a workshop on one tired 100A service. Googled "electrical panel replacement near me" expecting a runaround — instead got a clear plan for a 400A service with a sub-panel out to the barn. Hydro One coordination handled, inspection passed first try.

Honestly expected to be sold a full replacement. The electrician looked at the panel, said it was a decent modern unit with one bad breaker and a loose neutral, and did a panel repair for a fraction of what I'd budgeted. That honesty is why they'll get the call when we do finish the basement.

Adding a heat pump and a hot tub pushed us over what the old panel could handle. The 200 amp panel upgrade was quoted flat-rate, permit included, and power was only off for about five hours. The home inspector on our refinance commented on how clean the panel work was.
