Common problems we fix

No job is too small. If something electrical in your home isn't working the way it should, it's worth a call.

Breaker keeps tripping

A breaker that trips under normal use is telling you something: an overloaded circuit, a failing appliance, a loose connection or a worn-out breaker. We track down which one it is.

Dead outlets or switches

One outlet, a whole wall, or a switch that stopped doing anything. Often it's a tripped GFCI somewhere else or a loose connection, and we'll find it.

Flickering or dimming lights

Lights that flicker or dim when something else turns on can be a simple fixture issue or a sign of a loose connection that needs attention.

Part of the house has no power

When a room or a whole section of the house goes dead and resetting breakers doesn't help, we trace the circuit back and fix the cause.

GFCI won't reset

Bathroom, kitchen, garage and outdoor GFCI outlets that won't reset, or keep tripping, usually point to moisture or a fault further down the line.

Storm or lightning damage

After a storm, surge or lightning strike, we check what was affected, repair the damage and can add whole-home surge protection to help next time.

Call right away if you notice
  • A burning smell or smokeFrom an outlet, switch, fixture or the panel
  • Scorch marks or melted plasticOn outlets, plugs or around breakers
  • An outlet or panel that feels hotOr buzzes and crackles
  • Sparks or arcingWhen plugging something in or flipping a switch

If it's safe to do so, switch off that circuit's breaker and leave it off, then call or text us at (613) 265-9604. If there's fire or immediate danger, call 911 first.

“I had an excellent experience with Cornerstone Electrical installing the charger for my Ford Mustang Mach-E. The installation was done professionally, everything was neat and well organized, and the entire process was smooth from start to finish. The electrician was incredibly friendly, knowledgeable, and took the time to answer all of my questions. It’s clear they take pride in their work. I highly recommend Cornerstone Electrical to anyone looking for a reliable EV charger installation. Five stars all the way!”
