Whole-Home Rewiring in Los Angeles
Knob & tube, aluminum branch wiring, and old cloth-insulated circuits replaced with modern copper — permit-pulled and inspected.
Starting from$6,500
Typical project3–7 days
LA has thousands of homes still operating on wiring installed before World War II. Knob & tube, rag-insulated cloth wire, and mid-century aluminum branch circuits were safe for their era but aren't rated for modern loads. Rewiring is disruptive but not as bad as most homeowners fear — we work room by room, patch where possible, and keep power on to the rest of the house during the project.
Wiring systems we replace
- Knob-and-tube (pre-1950s homes)
- Cloth-insulated two-wire circuits (1950s–1960s)
- Aluminum branch wiring (1965–1975 — a known fire hazard)
- Undersized 14-gauge circuits carrying heavy modern loads
- Circuits with no ground conductor
- DIY splice work and unpermitted additions
What you get
- Modern copper wiring throughout, grounded and code-compliant
- Arc-fault (AFCI) and ground-fault (GFCI) protection where required
- New outlets and switches wherever existing ones are replaced
- Insurance-friendly documentation package for your carrier
- Drywall patch-back included (final paint by homeowner)
- Permit pulled, inspected, and signed off
Frequently asked questions
Do I need to move out during a rewire?
Most homeowners stay in the home. We work in sections so that the kitchen, at least one bathroom, and the sleeping areas have power every night. Only rare full-gut remodels require the house to be vacant.
How much wall damage will there be?
We fish wires through existing walls wherever possible. Some patching is unavoidable — usually 6"×6" access holes near outlets and switches. We patch to 'primed and ready for paint' as part of the job.
Is aluminum wiring actually dangerous?
Older single-strand aluminum branch wiring (common 1965–1975) has a documented fire-risk history due to expansion/contraction loosening connections. Modern multi-strand aluminum feeders are fine. If you have pre-1975 aluminum branch circuits, your insurer almost certainly wants them replaced or at minimum 'pigtailed' with approved AlumiConn connectors.
How long does a full rewire take?
A typical 1,500-sq-ft single-story home takes 4–6 working days. Two-story and larger homes take 7–10 days. Partial rewires of specific problem areas can often be done in 1–2 days.
