A breaker that trips every few days is telling you something, and it is rarely what the breaker itself suggests. Ajax Electrical Services is called when a fault has already been chased once and never actually found, across homes, shops and industrial units throughout Ajax. Our work runs from panel replacement and full rewires to EV charger circuits, and our emergency electrical services cover the faults that will not wait.
Everything is priced before a tool comes out, notified to the ESA where the work requires it, and inspected before we leave. Ask for electrical estimates and you get a figure that holds, whether the job is a single circuit or commercial electrician services across a whole tenancy in Ajax. We also fit backup generator installation and solar battery backup, and design commercial backup solutions for sites that cannot afford to go dark.
No handover to a subcontractor halfway through. The person who priced the work is the person testing the circuits before the panel closes.
We do not replace the breaker and hope. The circuit is loaded, measured and read until the actual fault shows itself.
The figure you approve is the figure invoiced. Anything unexpected is raised with you before it is touched, never after.
We notify, book the inspection and give you the paperwork your insurer will eventually ask to see.
Electrical work is the part of a property nobody thinks about until it fails. Bringing it up to current standards pays back in safety, capacity, and lower running costs for decades.
Old panels, undersized wiring, and dated fixtures waste energy as heat. Modern circuits and LED lighting draw less and hold a steadier load.
An EV charger, a heat pump, or a finished basement all need headroom in the panel. A service upgrade gives you room to add them without tripping the main.
Aluminium branch wiring, knob-and-tube, and loose backstab connections are the faults that start fires. Replacing them takes the hazard out of the walls.
Lights that dim when the dryer starts and breakers that trip on a kettle point to an overloaded circuit. Properly sized circuits hold steady room to room.
Most repeat faults come back because the symptom was replaced and the cause was never found. Property owners in Ajax use Ajax Electrical Services for electrical repair, covering fault tracing, testing under load, terminations, and lasting fixes.
Tandem breakers filling a board are a sign the service is already at its limit, not a clever use of space. Homeowners in Ajax use Ajax Electrical Services for panel upgrades, covering demand recording, service sizing, bonding, and inspection.
A licence is what makes the certificate at the end of the job worth anything to anybody else. Property owners in Ajax use Ajax Electrical Services for a licensed electrician, covering individual licensing, insurance, testing, and documentation.
Running an extension lead permanently is a sign the room is short of outlets, not short of leads. Homeowners in Ajax use Ajax Electrical Services for outlet installation, covering new circuits, cable routes, box mounting, and testing.
Machinery that starts sluggishly or trips on load is usually starved by its feed rather than worn out. Businesses in Ajax call Ajax Electrical Services for equipment wiring, covering feeders, disconnects, motor starters, controls, and commissioning.
A charger draws continuously for hours, which is a very different demand from anything else in the house. Property owners in Ajax use Ajax Electrical Services for charger installation, covering capacity checks, dedicated circuits, permits, and inspection.
Every panel and circuit is sized from a real load calculation rather than a guess, so adding an EV charger or a heat pump later does not push the service past what it can carry.
Dispatch runs seven days a week and an on-call electrician answers after hours, because no power, a burning smell, or a breaker that will not reset cannot wait until Monday.

We file the notification, book the inspection, and hand over the certificate at close-out. It is the step most quotes leave out and the one your insurer asks for.
Drop sheets go down, cuts get patched, and the panel directory is typed rather than scrawled. The property looks untouched apart from the work you asked for.

Level 2 chargers on dedicated circuits, with the load check and the permit handled before the unit goes up.

Whole-home backup sized to real load, commissioned and tested under power before handover.
Learn More about Standby GeneratorsA 60 or 100 amp service, a board with no spare ways, or breakers that trip whenever two appliances run together. Ajax Electrical Services replaces the service and sizes it for what the property draws today across Ajax.
We file the notification, book the inspection and hand over the certificate, so the upgrade is documented as well as done.
Knob-and-tube and early aluminium are the two things an insurer asks about, and both are replaced across Ajax without stripping the building back to studs.
Dead outlets, flickering lights and breakers that will not stay in are traced to the actual fault rather than patched at the socket.
A Level 2 charger needs a dedicated circuit and a free double pole in the panel, and Ajax Electrical Services checks both exist before quoting anything across Ajax.
Most attached-garage installs come down to cable length and panel headroom, which is why the price is confirmed after the survey, not before.
When the supply drops, an automatic transfer switch decides whether you notice at all. Ajax Electrical Services sizes and installs standby power for properties across Ajax.
Every installation is commissioned and tested under real load before handover, so the first genuine outage is not also the first test.

Our kitchen breaker tripped every time the kettle and toaster ran together. The electrician traced it to two circuits sharing a neutral, split them properly, and labelled the panel while he was in there. It has not tripped once since.
We needed a 200 amp service before the EV charger could go in. Ajax Electrical Services pulled the permit, did the upgrade in a day, and had the inspection booked before they left. The rebate paperwork was handled too.
Half the outlets on our main floor died overnight. Someone came out the same afternoon, found a burnt backstab connection in a bedroom box, and replaced every device on the run. Power was back before dinner.
Our shop kept losing the compressor circuit mid-shift. Ajax Electrical Services load tested the panel, found it was undersized for what we had added, and rebuilt the subpanel around the real draw. No downtime since the change.
I was quoted for a full rewire by two other companies. These folks tested the circuits first and found one bad junction box instead. They charged me for the hour it took and explained exactly what they ruled out.
The standby generator install ran a day longer than quoted because of where the gas line sat, which was fair enough. Ajax Electrical Services held the original price anyway and walked me through the transfer switch before they left.
Don't see your area listed? We likely still serve you — just ask.
Yes. Every service change needs an electrical notification filed and an inspection booked before the work is signed off, with no exceptions for like-for-like swaps. We file the notification within 1 business day of your approval, schedule the inspector, and hand you the Certificate of Acceptance at close-out. Keep that certificate, because it is the document your insurer asks for when you renew.
Most attached-garage installs land between $900 and $1,800, and the two things that move the number are the length of the cable run and whether your panel has a free double-pole slot. A ten minute load check tells us which end of that range you are on. You get a fixed written price before any work starts.
Usually. We hold same-day slots every weekday for no-power calls, burning smells, and breakers that will not reset, and an electrician is on call after 10PM for genuine emergencies. If we cannot reach you the same day we will tell you when you call rather than after you have waited. Booked work such as panel upgrades is typically scheduled within 5 to 10 business days.
Every job carries 2 years on our labour plus the manufacturer warranty on any panel, breaker, or device we supply, which usually runs 1 to 10 years depending on the part. The terms are printed on your invoice rather than buried in a policy document. Ajax Electrical Services honours that labour warranty regardless of which of our electricians did the original work.
Regularly, and it is one of the most common reasons property owners in Ajax call us. We can replace the wiring in stages if the budget calls for it, starting with the circuits insurers flag first, and we provide the documentation and certificate they require before renewing. Most full-house rewires run 3 to 5 working days depending on the number of circuits and whether the walls are open.
Three signs matter most: a service rated at 60 or 100 amps, a panel with no spare breaker slots left, and breakers that trip when two ordinary appliances run together. Any fuse panel, or any panel carrying a recalled brand, should be assessed regardless of how it is behaving. We run a load calculation across Ajax properties and tell you honestly whether an upgrade is needed or whether a subpanel solves it for less.
A standard 100 to 200 amp service upgrade is a single day on site, and your power is off for roughly 4 to 6 hours of that while the service is swapped and terminated. We give you the shut-off window the day before so you can plan around fridges, freezers, and any work-from-home commitments. The inspection is usually booked within 2 business days of completion.
Every electrician on our crews holds a valid licence, and the company carries $5 million in liability coverage plus full WSIB clearance. We subcontract nothing, so the person who quoted your job is the person on your property doing it. Ajax Electrical Services can send current copies of the licence, insurance certificate, and WSIB clearance before we start if you would like them on file.
