Signs You Need Circuit Breaker Replacement
Don't ignore these warning signs—a failing breaker can be a fire hazard.
Breaker Trips Repeatedly
A breaker that trips frequently—even after resetting—indicates it's worn out or there's an underlying circuit problem that needs diagnosis.
Breaker Won't Reset
If a breaker trips and won't stay in the "on" position, it's likely failed internally or there's a serious fault on the circuit requiring immediate attention.
Burning Smell or Scorch Marks
Any burning odor, discoloration, or melting around a breaker is an emergency. This indicates overheating that could cause a fire.
Buzzing or Humming Sounds
Breakers should operate silently. Buzzing, crackling, or humming from your panel indicates loose connections or a failing breaker.
Breaker is Hot to Touch
Warm breakers under heavy load are normal, but hot breakers indicate a problem. Excessive heat damages breakers and wiring connections.
Old or Recalled Breaker Brand
Federal Pacific, Zinsco, and some Challenger breakers are known fire hazards. If your panel has these brands, replacement is strongly recommended.
⚠️ Do You Have Federal Pacific or Zinsco Breakers?
These brands have high failure rates and are associated with thousands of house fires. Common in Mimico's 1920s-1950s bungalows and post-war apartments. Many won't trip during overloads, allowing wires to overheat. We recommend immediate replacement of all FPE Stab-Lok and Zinsco breakers.

Real reviews from breaker replacement and repair jobs.
"Our 1940s bungalow on Lake Crescent had a breaker that kept tripping whenever we ran the washing machine. Kolji Bros diagnosed an old Federal Pacific breaker and replaced it with a modern AFCI unit. No more trips and we have better fire protection now!"
"Living in Humber Bay Shores, our condo's AC breaker failed during summer. Kolji Bros came same day, had the right 240V breaker in stock, and had our air conditioning running again within 90 minutes. Lifesavers during a heat wave!"
"My Mimico Village home near Royal York had multiple breakers showing scorch marks. Kolji Bros did a thorough safety assessment, found Zinsco breakers that were fire hazards, and replaced all six in one visit. Professional and transparent pricing throughout."
Circuit Breaker Replacement FAQ
Common questions about breaker repairs and upgrades.
Standard single-pole breaker replacement typically costs $150-$250 including parts and labor. AFCI and GFCI breakers cost more ($250-$350) due to the higher cost of the breakers themselves. Double-pole 240V breakers fall in a similar range. We provide exact quotes before starting.
Common causes include circuit overload (too many devices), a short circuit in wiring or an appliance, a ground fault (especially in wet areas), or a worn-out breaker. We diagnose the root cause—sometimes it's the breaker, sometimes it's what's plugged into the circuit.
In Ontario, electrical work must be done by licensed electricians or homeowners who pull permits. Working inside a live panel is dangerous—even with the main off, the utility feeds remain energized. We strongly recommend professional replacement for safety.
If the breaker trips even with minimal load, trips immediately after resetting, won't reset at all, or shows physical damage (burn marks, won't stay in position), the breaker is likely bad. If it only trips when you're running multiple high-draw devices, it's probably overloaded.
AFCI (Arc-Fault) breakers detect dangerous electrical arcs that cause fires—required for bedrooms and living areas. GFCI (Ground-Fault) breakers detect current leaking to ground (electrocution risk)—required for kitchens, bathrooms, outdoors. Dual-function breakers provide both protections.
Simple like-for-like breaker replacements typically don't require permits. However, upgrading to AFCI/GFCI breakers, adding new circuits, or replacing main breakers may require ESA notification. We handle all permit requirements when applicable.
Quality breakers typically last 25-40 years under normal conditions. However, breakers that trip frequently, experience power surges, or are in hot environments wear out faster. If your panel is 30+ years old, breakers may be nearing end of life.
Not necessarily—one failed breaker doesn't mean they'll all fail. However, if you have Federal Pacific, Zinsco, or other recalled brands, we recommend replacing all breakers (or the entire panel). If multiple breakers are failing in an older panel, it may be time for a full upgrade.
