Electrical troubleshooting and repairs for North York homes
A breaker that won't hold, a row of dead outlets, lights that sag when the furnace starts. We trace the fault to its source, explain it plainly, and repair it once you've approved the price.
Where faults hide in North York
Seventy years of changes behind the drywall
Most North York houses were built between the late 1940s and the 1970s. Very few still have only their original wiring. Over the decades, owners finished basements, moved kitchens, added central air and turned bedrooms into offices.
Some of that work was permitted and done well. Some was not. Faults today often sit where old wiring meets new. Think of a junction box sealed behind a basement ceiling, or a splice left from a 1980s renovation.
So a dead outlet in a Willowdale or Lansing bungalow is seldom fixed by swapping the outlet. First we work out how the circuit really runs, which is not always what the panel directory claims.
Diagnostics learned at Toronto Hydro
Shaldin Marrast learned troubleshooting and diagnostics at Toronto Hydro before founding Marrast Contracting, and he still leads every crew. On a service call that shows in the order of the work. Questions come first, then the meter, then the repair.
Split-levels, common in parts of Don Mills and Parkwoods, need extra patience. Circuits wander between half-floors, so the GFCI or loose connection behind a dead outlet can be one level away.
Common North York calls
What we're asked to fix most here
Breaker keeps tripping in a finished basement
Basements finished decades ago often hang a whole floor on one or two circuits. Add a space heater or a treadmill and the breaker gives up.
Outlet not working but the breaker isn't tripped
Look for a GFCI outlet in a bathroom, the garage or outside that has tripped and cut power to others on its run. If that's not it, a loose splice or worn outlet upstream is next.
Lights that sag when the AC starts
Typical where central air was added to a bungalow on a busy service. It can also mean a loose connection at the panel.
Warm outlets in a 1970s house
Some homes from the late 1960s and 1970s have aluminum branch wiring. Loose or mismatched connections on it run hot and need a proper repair.
Nuisance trips in a new rebuild
Large custom homes put arc-fault and ground-fault protection on many circuits. A shared neutral or a faulty appliance can set them off.
Trouble after a windstorm
Falling branches on North York's treed streets can damage the overhead drop or pull the mast. We check your side and tell you if it's Toronto Hydro's.
Half the house dark
Often a lost leg of the service or a failing main breaker. We help you tell which one, and who needs to come.
By home type
Bungalow, condo or custom rebuild
The house you live in shapes where the fault is likely to be and who else gets involved.
| Post-war bungalow or split-level | Condo along Yonge | Custom rebuild | |
|---|---|---|---|
| Usual complaint | Tripping, dead outlets, dimming | A dead suite circuit or a breaker that won't reset | Arc-fault or ground-fault trips, lighting controls acting up |
| Where we start | Old splices, overloaded shared circuits, the panel | The suite panel and the devices inside the unit | Shared neutrals, appliance faults, control wiring |
| Who else is involved | Usually just you | Property management, for access and building equipment | Sometimes the builder |
| Typical result | A targeted repair, sometimes a new circuit | A repair inside the suite, booked through management | A wiring correction or a faulty device replaced |
On a North York call
From the first question to a tested repair
Tell us the symptom
By phone or the form. Anything that sounds dangerous is handled as an emergency.
We book the visit
Netsayi confirms the time. Condo visits go through your property manager.
Testing on site
We isolate the circuit, test each device and splice, and find what failed.
Price before repair
You hear the cause and the cost of fixing it before we touch anything.
Repair and paperwork
Fixed, tested and, where the work needs it, permitted with ESA.
Bigger than one circuit
When the fault is a symptom
Sometimes a repeat fault is telling you something larger. It might be a full panel, a 100 amp service carrying central air and an induction range, or wiring that keeps failing in new places. We'll say plainly when patching no longer makes sense.
We put the options in writing. They may include a panel upgrade in North York or a partial rewire of a North York home. Want the whole picture first? Book a full electrical inspection.
Burning smell or buzzing?
Don't wait for an appointment
Switch off the circuit if you can reach it safely, keep away from the panel if it's hot or scorched, and call our 24/7 line.

Troubleshooting and repairs in North York: questions
The basement lights in my Willowdale bungalow flicker, but upstairs is fine. What causes that?
Usually something on the basement circuits themselves. Common culprits are a loose splice at a fixture, a dimmer not rated for LED lamps, or a neutral disturbed in an old renovation. Because it stays on one floor, the service is rarely to blame. We measure at the panel and at the fixtures to find where the voltage drops.
Something in my condo stopped working. Do I call you or the building?
Start with your property manager. Wiring inside your suite, after the suite panel, is generally the owner's to repair, while corridors, risers and electrical rooms belong to the corporation. Once management confirms it's on your side, we book the visit through them and follow the building's rules.
A branch tore the wire off my house in a storm. Who fixes it?
Stay well back and call Toronto Hydro first: the line from the pole is theirs to make safe. The mast, weatherhead and meter base on your house are usually your responsibility. We repair that equipment, file the ESA permit and arrange the reconnection with Toronto Hydro.
How does a service call work?
A service or diagnostic call is a first visit to find the cause of a problem. We give you the rate when you book, test the circuit, tell you what we found, and give you the price to fix it before we do any work. Many simple jobs can also be priced from photos.
