Electrical repairs cover the everyday faults that make a home's wiring unreliable: an outlet that has gone dead, a breaker that trips for no obvious reason, lights that flicker, a switch plate that feels warm, or a fixture that works only some of the time. Most of these start small, often as a loose connection, a worn device or a circuit asked to carry more than it was designed for, and most can be fixed in one visit once the cause is found.
Finding that cause is the real work. A dead outlet may have lost power because a ground-fault device in another room has tripped, and a flickering light may point to a failing fixture, a loose splice in a junction box or a problem back at the panel. A licensed electrician traces the circuit, tests it and repairs the fault where it starts, instead of swapping parts until the symptom goes quiet.
This guide covers the faults homeowners call about most, the warning signs that turn a repair into a same-day call, what happens during a diagnostic visit, and why even a small repair is regulated work in Canada, including in older homes wired with aluminum or knob-and-tube.
Common electrical faults: dead outlets, tripping breakers, flickering lights and warm switch plates
- Dead outlets: a receptacle with no power often sits downstream of a tripped GFCI outlet elsewhere on the circuit, but it can also mean a loose or burnt connection inside the box.
- Breakers that trip over and over: an overload, a short circuit, a ground fault or an arc-fault breaker reacting to damaged wiring can all be the cause, and each calls for a different repair.
- Flickering lights: a loose bulb or a failing fixture explains flicker in one spot, while flicker across several rooms suggests a loose connection further back on the circuit or at the panel.
- Warm switch plates or outlet covers: a dimmer can run slightly warm by design, but a plain switch or receptacle that feels hot usually has a loose terminal or too much load on it.
- Burning or hot-plastic smells: a sign that insulation or a device is overheating somewhere on the circuit, even when nothing looks wrong from the outside.
- Buzzing or crackling from a switch, an outlet or a fixture: often the sound of current arcing across a loose connection.
When an electrical repair can't wait: burning smells, sparks and hot devices
Some faults can be booked for later in the week; others can't. A burning smell, sparks or a flash when something is plugged in, scorch marks on a cover plate, or an outlet, switch or panel that is hot to the touch mean something is overheating right now. Stop using the circuit, switch it off at the breaker if the panel is dry and safe to reach, and get an electrician in the same day, through an emergency service if needed. If you see smoke or flames, leave the house and call 911.
Milder symptoms still deserve a prompt booking: a light flickering on one circuit, an outlet that stopped working, or a GFCI that won't reset. They rarely turn into an emergency overnight, but loose connections tend to get worse with heat and time, so avoid leaving them for months and working around them with extension cords.
What happens during an electrical diagnostic visit
A repair visit starts with questions: when the problem began, whether it depends on the weather, the time of day or a particular appliance, and what has changed in the house lately, such as a renovation or a new heater. Those answers narrow the search before a single cover comes off.
- The electrician checks the panel for tripped breakers, signs of heat and damaged connections, and confirms which breaker feeds the faulty circuit.
- Ground-fault and arc-fault devices on the circuit are tested and reset, since one of them is often why several outlets go dead at once.
- Test instruments confirm voltage, polarity, grounding and the condition of the circuit, so the fault is located rather than guessed at.
- Outlets, switches and junction boxes along the circuit are opened in turn to find the loose splice, the burnt terminal or the failed device.
- The faulty part is repaired or replaced, the circuit is retested with a load on it, and you get a written note of what was found and done.
- If the fault turns out to be a symptom of something larger, such as an overloaded panel or deteriorated cable, the electrician explains the options before going further.
Licensed electricians only: notification and permit rules for electrical repairs
A small repair is still regulated electrical work. ESA states that if you need someone to do electrical repairs in your Ontario home, by law you must hire a Licensed Electrical Contractor who takes out a notification, ESA's permit, for the work. In Quebec, repairs done for someone else go to a contractor licensed through the CMEQ, and in British Columbia, Technical Safety BC or the local government issues the electrical installation permit. Other provinces and territories have their own authority, so the rules follow the address, not the size of the job.
Declaring a repair shouldn't slow it down: the contractor files the notification or permit and arranges the inspection where one applies. If opening a box reveals more than expected, such as heat-damaged cable inside the wall, ask for it to be included in the declared work rather than patched around, and keep the confirmation with your house records.
Repairing circuits with aluminum or knob-and-tube wiring, and what insurers ask
Older wiring changes how a repair is done. On aluminum branch circuits, which ESA says may be found in homes built from the mid-1960s to the late 1970s, the weak points are the connections, so a replacement outlet, switch or splice has to use devices and connectors compatible with aluminum or an approved method of joining it to copper. A standard device fitted in its place is not a like-for-like repair.
Knob-and-tube has no ground wire, and ESA notes that many insurers will not provide or renew coverage on homes that still have it. When a repair touches one of these circuits, ask the electrician to describe the condition of the wiring in writing. That note answers an insurer's questions and helps you decide whether to repair the circuit or plan a rewire.
Repair the device or replace the circuit: how electricians decide
- A single worn receptacle, switch or breaker with sound wiring behind it is a straightforward repair.
- Heat damage that has spread into the cable insulation means replacing the damaged length of cable, not just the device at the end of it.
- A circuit that trips from overload rather than a fault needs the load spread out or a new circuit added, which is new work rather than a repair.
- Repeated faults in several rooms, brittle insulation or amateur splices point toward partial rewiring.
- Scorched connections in the panel or breakers that won't stay on lead to a panel repair or replacement, quoted separately.
- Two-slot outlets can't simply be swapped for three-slot ones without a ground; the electrical code allows specific solutions, such as bonding to ground or ground-fault protection, and the electrician picks the right one.
Why electrical faults show up in winter: space heaters, block heaters and outdoor outlets
Many repair calls come in the cold months. Space heaters plugged into bedroom circuits that already feed other loads trip breakers and heat up receptacles, baseboard thermostats wear out after years of cycling, and outdoor outlets used for block heaters and holiday lights take in moisture and ice. A warm plug, a cord that's hot to the touch, or an outdoor outlet that trips its GFCI in wet weather are all worth mentioning when you book, because they point the electrician straight to the right circuit.
Electrical Repairs: frequently asked questions
Why did several outlets stop working at once?
Often because a GFCI outlet upstream, in a bathroom, the garage or outside, has tripped and cut power to the outlets it protects, and pressing its reset button brings them back. If nothing resets, or it trips again right away, the circuit has a fault and needs an electrician.
Is it normal for a light switch to feel warm?
A dimmer can feel slightly warm because it gives off a little heat as it works. A standard switch or an outlet shouldn't. If one feels hot, smells or is discoloured, stop using it, switch off its breaker and have an electrician check it.
Why do my lights flicker?
A single fixture that flickers usually has a loose bulb, a failing LED driver or a worn switch. Flicker across several rooms, or lights that brighten and dim together, suggests a loose connection in the panel or the service, and should be checked promptly.
Can I replace a dead outlet myself?
Leave it to a licensed electrician. In Ontario, ESA says electrical repairs you hire out must be done by a Licensed Electrical Contractor under a notification. And a dead or hot outlet is usually a symptom: a new device won't fix a burnt splice, a damaged cable or a failing breaker.
Does a repair on aluminum wiring need special parts?
Yes. Connections are the weak point on aluminum circuits, so any replacement outlet, switch or connector must be compatible with aluminum or joined with an approved method. Mention the wiring when you book so the electrician comes prepared.

What affects the cost of electrical repair
Prices depend on the details of your project. We only publish price ranges when they’re backed by real LokalMatch quote data or reliable sources. Until then, here’s what usually changes the price:
- Type and amount of work, from a single fixture to a full rewire
- Condition and age of the existing wiring
- Panel and service capacity
- Distance from the panel to the new circuit
- Access through finished walls and ceilings
- Permits and inspections
How to compare electricians before you hire
- Hire a licensed electrician or electrical contractor for any wiring, panel or new circuit work.
- Ask whether the work needs a permit and inspection, and make sure the electrician arranges it.
- Get a written quote that lists fixtures, materials, patching of walls and ceilings, and permit costs.
- For panel upgrades and EV chargers, ask them to check whether your electrical service can handle the added load.
- Choose someone who explains what they found in plain language before starting.
Questions to ask electricians before you hire
- Are you licensed for electrical work in my province?
- Will you get the permit and arrange the inspection?
- Can my current panel and service handle this work?
- Will you need to open walls or ceilings, and who patches them afterwards?
- Is the price fixed, or could it change once you see the existing wiring?
- What warranty do you offer on your work?
When to call a pro for electrical repair
- Burning smells, scorch marks or warm outlets and switches: turn off the circuit at the panel if it's safe to do so and call an electrician.
- Breakers that trip again and again
- Flickering or dimming lights that aren't fixed by changing the bulb
- Any sparking, buzzing or exposed wiring
Electrical repair permits and local rules
Some electrical repair work needs a permit or has to meet local bylaws. Rules vary by municipality, so ask your pro whether a permit is needed and who will apply for it — and check with your city or town if you’re unsure.
