Smoke-Damaged Wiring After the Eaton Fire: What to Check

The Eaton Fire destroyed thousands of homes, but many more in Altadena, Pasadena and Sierra Madre are still standing with smoke, soot and ash inside. Those homes can look fine and still have electrical problems that show up months later: a breaker that starts tripping, an outlet that gets warm, a smell from the panel. LA County's damage teams only walked around the outside of buildings, and their checks didn't look at smoke, ash or soot. So if your home made it through, the wiring inside may never have been checked by anyone. We're a licensed C-10 electrical contractor based in Pasadena, and this is what we look at in smoke-exposed homes. If something below sounds familiar, request a free estimate or call 747-255-8595.

Why Smoke Matters to Your Wiring

Smoke and soot don't stay on the walls. They get pulled into outlet and switch boxes, light fixtures, attic and crawl-space wiring, and the electrical panel itself, especially in older homes with gaps around the panel cover. Soot can be corrosive and can hold moisture, which is hard on breaker contacts, bus bars and terminal screws. Heat that didn't burn the house can still soften wire insulation in the attic or near the eaves, and wind-driven embers can damage the service entrance, meter area and exterior outlets. None of this has to be visible from the living room.

Many standing homes in Altadena and north Pasadena are older, with original panels, ungrounded circuits or even knob-and-tube wiring. Wiring that was already near the end of its life is the most likely to give trouble after smoke and heat exposure.

Warning Signs to Watch For

Call a licensed electrician if you notice any of these:

Black film or soot inside outlet covers, switch plates or light fixtures. Turn off the circuit before you remove a cover plate to look.
A breaker that trips more often than before the fire, or one that won't reset.
Outlets or switches that feel warm, buzz, or spark when you plug something in.
A burning or melted-plastic smell that comes back after the house is cleaned.
Flickering or dimming lights, or 240-volt appliances that run weakly.
Damage outside: a scorched or bent meter enclosure, service wires or weatherhead, or melted exterior outlets and fixtures.
A hot or discolored panel cover. Don't remove the panel cover yourself.

If you smell burning and can't find the source, turn off the main breaker if it's safe to reach and call us. We offer 24/7 emergency electrical service.

What a Post-Fire Electrical Inspection Covers

A good electrical safety inspection after smoke exposure goes beyond flipping switches. We open the panel and look at breakers, bus bars and connections for soot, corrosion and heat marks. We check the service entrance, meter area and grounding. We spot-check outlet and switch boxes on each circuit, look at attic and exterior wiring where heat and embers reached, and test GFCI and AFCI protection, smoke alarms and CO alarms.

You get a clear answer: what's fine, what needs cleaning or replacement, and whether the panel itself should be replaced. Some smoke-exposed panels clean up. Others, especially older panels with known problems, are better replaced, and a panel upgrade is often the moment to add capacity for a heat pump, EV charger or battery. Repairs and panel replacements need a permit from your city or the County, and a licensed electrician pulls it.

Getting Power Back if You Were Red-Tagged

If your home was red-tagged or its electrical equipment was damaged, the utility won't turn power back on until the problem is fixed and inspected. SCE's process for its customers, including Altadena and Sierra Madre, is:

Repair: A licensed electrician repairs the damaged equipment on your property. SCE says the owner is responsible for equipment on their side.
Permit: Your city or LA County issues the electrical permit.
Inspection: A city or County inspector confirms the repairs are safe and sends an inspection release to SCE. In unincorporated Altadena that's LA County Public Works Building & Safety.
Reconnect: Call SCE at 1-800-655-4555 to request service restoration, and SCE schedules the reconnection.

SCE's disaster recovery line is 1-800-250-7339 (weekdays 7 a.m. to 7 p.m., Saturdays 8 a.m. to 5 p.m.). SCE's Altadena Rebuild & Community Hub at 2680 Fair Oaks Ave. is open weekdays 8 a.m. to 5 p.m., and SCE also has walk-in help at the LA County Permit One-Stop, 464 W. Woodbury Rd., Suite 210.

Pasadena homes are served by Pasadena Water & Power, not SCE. Call PWP customer service at 626-744-4005 or its power emergency line at 626-744-4673, and the City of Pasadena handles the permit and inspection. Not sure which utility serves you? See our PWP vs. SCE guide.

Insurance, Claims and Timing

Document what you find before work starts: photos of soot in outlet boxes, the panel and any damage outside. Insurance adjusters and claim programs ask for it, and our inspection notes can help. SCE's voluntary Wildfire Recovery Compensation Program for people affected by the Eaton Fire is open through Nov. 30, 2026, according to SCE. We don't handle claims, but we can document the electrical condition of your home so you have it in hand.

If you're rebuilding from the ground up instead, our Altadena rebuild wiring guide covers temporary power, SCE service requests and County permits.

Frequently Asked Questions

Can smoke damage electrical wiring?

Yes. Soot and smoke can get into outlet boxes, fixtures and the panel and can cause corrosion over time, and nearby heat can damage wire insulation. Problems may not show up right away.

My house wasn't burned. Do I still need an electrical inspection?

If there was smoke, soot or ash inside, it's a good idea. LA County's damage assessments only looked at the outside of homes and didn't cover smoke, ash or soot.

How do I get SCE to turn my power back on after a red tag?

Have a licensed electrician make repairs under a permit, pass the city or County inspection, then call SCE at 1-800-655-4555. The inspector sends the release to SCE.

Do I need to replace my electrical panel after smoke damage?

Not always. Some panels can be cleaned and repaired. Corroded, heat-damaged or already outdated panels are usually better replaced, with a permit.

Who handles power for Pasadena homes after the fire?

Pasadena Water & Power. Call PWP at 626-744-4005, or 626-744-4673 for power emergencies. Altadena and Sierra Madre are served by SCE.
