Not every flicker means the same thing. Here are the causes our clients call us about most often.
A single fixture that flickers on its own usually points to a loose bulb, a worn socket, or a loose wire connection inside the fixture box. Left alone, the loose connection can generate heat and become a safety concern over time. We check the socket and wiring and correct the loose connection.
A brief dim or flicker when a major appliance starts up is often caused by the motor's temporary voltage draw, especially on an older or undersized circuit. A flicker that's severe or affects small appliances too can mean the circuit is overloaded. We test the circuit's actual capacity against what's running on it.
Flickering that spreads across several rooms simultaneously usually points to a loose connection at the panel or main service entrance rather than an individual fixture issue. This kind of widespread instability can damage sensitive electronics if it continues. We inspect the panel and main connections to find the actual source.
A flickering or buzzing dimmer often means the switch isn't rated for the type of bulb installed, most commonly with LED bulbs on an older incandescent-rated dimmer. Continuing to use a mismatched dimmer can shorten bulb life and stress the switch. We match the dimmer to the correct bulb type and replace it if needed.
Flickering that shows up specifically during wind or rain often points to a loose connection at the meter base or service entrance being disturbed by movement or moisture. This kind of intermittent fault is easy to miss during a dry-weather inspection. We check the service connection under realistic conditions to confirm the cause.
LED bulbs flickering right after installation usually means an incompatibility with the existing dimmer switch or driver, since LEDs behave differently on a circuit than older incandescent bulbs. This isn't a wiring fault, but it does need the right fix to stop. We identify the compatibility issue and recommend the correct dimmer or bulb pairing.
A flicker that starts mild and gradually worsens usually signals a connection that's loosening further with heat cycling and use, rather than a stable minor issue. Waiting for it to fully fail risks a bigger disruption or safety concern later. We locate and correct the deteriorating connection before it fails completely.
Flickering combined with a warm switch plate or outlet cover points to heat building up at a loose or failing connection, which is a genuine early fire risk. This combination should never be treated as just an annoyance. We inspect and repair the connection immediately given the added safety concern.
Flickering that appears shortly after electrical or renovation work often means a connection wasn't fully secured during the project, even if the work looked complete. This kind of issue tends to worsen rather than resolve on its own. We inspect the recent work and correct any connections that weren't properly finished.
I'd replaced every bulb in the kitchen twice thinking that was the problem. The technician from Electrical Services Ontario found a loose neutral connection at the panel in about fifteen minutes. Lights have been rock solid since.
Turned out to just be a loose wire nut inside the fixture box, an easy fix once he got up there. In and out in under 30 minutes and he showed me exactly what was wrong before closing it back up.
He correctly identified a failing dimmer switch as the cause but didn't have the exact replacement on the truck. Had to schedule a quick follow-up two days later, though the actual repair itself only took ten minutes once he had the part.
Called about one flickering light in the hallway and Electrical Services Ontario found an overloaded circuit that was likely to cause more problems down the road. Glad they checked the whole circuit instead of just the one fixture.
I was worried the flicker every time the AC kicked on meant something was wrong. He tested the voltage drop, confirmed it was within normal range, and saved me from paying for a repair I didn't actually need.
Lights across the entire main floor had been flickering for weeks and two other companies couldn't figure it out. Electrical Services Ontario found a corroded connection at the meter base that nobody else had checked. Genuinely relieved to have it fixed.

Tell us what is happening — no power, a breaker that will not reset, or a planned upgrade. We talk it through and book a time that works for you, including same-day for urgent calls.
A licensed electrician looks at the actual panel, circuit, and load rather than quoting over the phone, then gives you a firm written price with the scope set out line by line.
The electrician who quoted the job does the work. Drop sheets go down, permits are filed where the work calls for it, and you get an update before anything changes from the plan.
Every circuit is tested before we close the panel, the inspection is booked and the certificate handed over, and our labour is warrantied for two years.
