Electrical Repair
Something in your wiring isn't working right, and you'd rather it be fixed properly the first time. Fair enough. Frank Chiavarini has run Interstate Electrical Contractors out of Glendora since 1981. He is offering affordable electrical repair across Glendora, Arcadia, and nearby cities, where he's spent more than 40 years fixing the electrical problems local homes and businesses face. Faulty wiring. Dead outlets. A breaker that keeps tripping for no clear reason. Power that drops in half the house while the rest stays on.
We fix all of it. Every repair is done by a California C-10 licensed electrical contractor, California license #415324, and you can verify it at cslb.ca.gov. So the work is safe, meets code, and isn't the kind of job you'll be paying someone else to redo later. When you book electrical repair service in Glendora, CA, Frank is the one who shows up. Not a rotating crew or a subcontractor you've never met.

What's Included in Our Electrical Repair Service
We cover the full range of residential and commercial repairs. Here's what that usually looks like.
Electrical troubleshooting & diagnostics
Sometimes the hardest part is figuring out what's actually wrong. Frank tracks the problem to its source instead of guessing, whether it's a loose neutral, a failing GFCI, an overloaded circuit, or something hidden behind a wall. You get a clear answer, not a shrug. This is the heart of good electrical troubleshooting in Glendora, and it saves you money because we fix the real issue the first time.
Wiring installation & rewiring repair
Old or damaged wiring is a safety risk, plain and simple. We handle wiring and rewiring repair for older homes, additions, and remodels. We replace anything that's frayed, outdated, or done wrong by a previous owner. Aluminum branch wiring and other decades-old setups are common in this area, and we correct them properly. If you need electrical wiring work in Glendora or a full rewire in Arcadia, that's routine for us.
Circuit and breaker issue repair
A breaker that trips over and over is trying to tell you something. We repair faulty circuits, replace worn breakers, add dedicated appliance circuits, and sort out panels that can't keep up with the load. If your lights dim when the AC kicks on, that's usually a circuit worth looking at. When a panel is past saving, we handle full panel installation and upgrades too.
Power outage and outlet troubleshooting
Lost power in one room but not the rest? Dead outlet that used to work? These are common calls, and they're usually fixable same day. We find the break in the line and get your outlets, switches, and lights working again, indoor or outdoor.
Code-compliant repair work
Every repair we do meets current California electrical code. That matters for your safety, and it matters if you ever sell or insure the property. Code corrections are a big part of what we do, especially in older Glendora and Arcadia homes that were wired decades ago.
Flickering lights or frequent breaker trips
The occasional flicker is nothing. But if it keeps happening, or a breaker trips again and again, there's usually a real problem behind it.
Warm outlets or switches
An outlet or switch should never feel warm to the touch. If it does, stop using it and call. That's one you don't want to sit on.
Partial power loss in the home
When power works in some rooms but not others, it points to a wiring or circuit fault. It won't fix itself, and it can get worse.
Burning smell near panels or outlets
This one's simple. A burning smell near your panel or an outlet means shut it off and call right away. Don't wait on this.
