Our Wiring and Rewiring Services

The wiring behind your walls handles every amp your home uses. When it’s old, damaged, or the wrong type, the symptoms show up as flickering lights, dead outlets, tripping breakers, burning smells, and in the worst case, fires. Los Angeles has a huge number of homes built between the 1920s and 1970s, and many of them still have original wiring that was never designed for the loads a modern household puts on it. Express Electrical repairs, replaces, and upgrades residential wiring across LA. From single-room fixes to whole-home rewires, we handle the scope, the permits, and the inspections. GreenSky financing available for larger projects.

The Wiring Landscape in Los Angeles

LA’s housing stock creates electrical wiring challenges unlike almost any other city. A massive percentage of homes across Silver Lake, Los Feliz, Echo Park, Highland Park, Atwater Village, Boyle Heights, and East LA were built between the 1920s and 1970s. Each era brought a different wiring method:

Homes built before 1940 often have knob-and-tube wiring, which uses porcelain knobs and tubes to route individual conductors through open air spaces in the walls and attic. It has no ground wire, and the rubber insulation has been disintegrating for decades.

Homes built from the 1930s through the early 1960s typically have cloth-insulated wiring. The fabric sheathing dries out, cracks, and flakes away, leaving bare copper exposed inside wall and ceiling cavities.

Homes built during the mid-1960s through mid-1970s may have aluminum branch circuit wiring. The aluminum itself conducts electricity fine, but the connections loosen over thousands of heating and cooling cycles, creating arcing and fire risk at every outlet, switch, and junction box.

Each of these wiring types has a specific set of risks, a specific set of solutions, and specific implications for insurance coverage. We’ve worked on thousands of LA homes with every combination imaginable.

How We Minimize Disruption

One of the biggest concerns homeowners have about rewiring is the mess. Tearing walls open, dust everywhere, a house in chaos for a week. We understand that fear, and we work to minimize it.

We access wiring through attic spaces, crawl spaces, and existing openings wherever possible. Modern wire-fishing techniques let us route new cable through wall cavities without opening every stud bay. Where drywall does need to come down, we identify the exact locations during planning so there are no surprises.

For partial rewires and room-by-room projects, we contain the work to the target area and keep the rest of the house operational. Power stays on throughout the project, with brief interruptions as individual circuits are transferred to new wiring.

The Insurance Factor

Insurance carriers in California are paying more attention to wiring than ever. Knob-and-tube, aluminum branch circuit wiring, and cloth-insulated wiring are all flagged during policy reviews. Some carriers won’t write or renew policies on homes with these wiring types. Others increase premiums or add exclusions.

If you’re having trouble getting or keeping homeowner’s insurance because of your wiring, replacing it resolves the issue and often reduces your premium. We provide documentation of the completed work for your carrier.

Frequently Asked Questions

How do I know what type of wiring my home has?

Check your attic, crawl space, or inside an outlet box. Knob-and-tube has porcelain insulators and individual conductors. Cloth-insulated wire has a woven fabric appearance, usually tan or brown. Aluminum wire is silver-colored and may be stamped “AL” on the jacket. If you’re not sure, we can identify it during an inspection.

Will I need to move out during a whole-home rewire?

Not usually. We work one section at a time and maintain power throughout. Brief interruptions happen as circuits are swapped, but you can stay in the home.

Does old wiring automatically mean it’s dangerous?

Not automatically, but the risk increases with age. Insulation degrades, connections loosen, and the wiring may not meet current safety standards. An inspection tells you exactly where you stand.

Can I rewire my home in stages?

Yes. Many homeowners do the kitchen and bathrooms first, then bedrooms, then the rest. We can plan a phased approach that spreads the cost over months or years.

What areas do you cover?

We serve Los Angeles County, Orange County, Ventura County, and Riverside County.
