House Rewiring in Los Angeles, CA

911 Construction & Electric Inc. rewires older homes across Los Angeles, Pasadena, Altadena, Glendale and the San Gabriel and San Fernando Valleys. LA has a huge stock of pre-war Craftsman bungalows, Spanish-style homes and mid-century houses, and many still have their original wiring behind the walls.

Does your house need rewiring?

• Knob-and-tube wiring: ceramic knobs and tubes with single insulated wires in the attic or crawlspace
• Cloth-insulated or brittle wiring at outlets and fixtures, or two-prong, ungrounded outlets throughout
• Aluminum branch wiring, common in some 1960s–70s homes → Aluminum wiring repair
• Frequent trips or blown fuses, lights that dim when appliances start, power strips everywhere
• Warm, discolored or buzzing outlets, or a burning smell (call now: emergency electrician)
• Insurance or a buyer's inspector flagged the wiring → Knob-and-tube and insurance

None of this means your house is about to burn down. It does mean the wiring should be evaluated by a licensed electrician. More: 7 warning signs your LA home needs rewiring · Knob-and-tube replacement

How a rewire works, step by step

1. Evaluation. We check the panel, open a sample of outlets, switches and fixtures, and look in the attic and crawlspace for knob-and-tube, cloth or aluminum wiring and amateur splices.
2. Plan and written estimate. New circuits room by room, kitchen and bath circuits, dedicated appliance lines, lighting, and smoke and CO alarms, plus room for an EV charger, heat pump or home battery. The estimate spells out the circuits, panel work, permit and schedule. For typical ranges, see cost to rewire a house.
3. Permit. Pulled under our C-10 license with LADBS, Pasadena, Glendale, LA County (for Altadena) or your local department. → Pasadena · South Pasadena permit guides
4. Rough-in. New cable fished through the attic, crawlspace and walls, using existing paths wherever we can, with openings in plaster or drywall kept as small as practical.
5. Rough-in inspection before walls are closed. → What to expect
6. Panel and connections. Often a new 200-amp panel if the old one was undersized or a Zinsco or Federal Pacific, with AFCI and GFCI protection where code requires it.
7. Trim, final inspection and walkthrough. New devices and fixtures, every circuit tested, the panel directory labeled, and a closed-out permit.

Timeline: most single-family rewires take three to ten working days, depending on size, access and whether walls are open. Permit and inspection scheduling add time.
