Short answer: Circuit & Cistern LA handles whole-home rewiring by checking the symptom, the system around it, and the local constraints that can change the repair. For this service, that means we replace obsolete or unsafe wiring with coordinated circuits, grounding, AFCI/GFCI strategy, panel planning, and inspection access.
The key risk is simple: rewiring is not just pulling cable; access, plaster repair, circuit mapping, panel capacity, and staged inspections matter. That is why the page includes cost drivers, what can go wrong, permit context, utility overlap, homeowner prep, and local pages instead of only a generic "call now" pitch.
older bungalows, duplexes, and additions often mix knob-and-tube, cloth, BX, and modern NM in the same home. The visit starts with symptom photos, model labels, shutoff access, and the relevant route from the equipment to the panel, pipe, drain, duct, or exterior location.
Typical planning range: $9 500 to $52 000. The low side usually assumes clear access, existing infrastructure that can stay, and no major hidden defects. The high side usually involves replacement equipment, utility involvement, difficult routing, permit or inspection sequence, concealed damage, or multi-trade coordination.
| Path | When it fits | What can change the scope |
|---|---|---|
| Repair | The equipment or fixture is serviceable and the failure is isolated. | Old parts, unsafe wiring, bad shutoffs, inaccessible cleanouts, or failed venting. |
| Replacement | The system is at end of life, unsafe, inefficient, or no longer compatible with the home. | Permits, HERS, panel capacity, pipe material, duct sizing, condensate, or gas sizing. |
| Retrofit sequence | Several home systems should be staged so one upgrade does not block the next. | EV charger, heat pump, HPWH, ADU, remodel, repipe, or whole-home rewiring plans. |
Misconception: Knob-and-tube is fine if it is not currently failing.
Reality: 1925-era K and T was rated for an open-air 14 AWG installation, not for buried-in-insulation use that became standard after the 1970s insulation push. Insurance carriers in California now flag K and T at policy renewal, and California Health and Safety Code section 17926 plus local AHJs treat insulated K and T as a hazard regardless of present continuity.
Misconception: Rewire means open every wall.
Reality: Modern fish techniques pull NM-B (Romex) or MC cable through plaster walls with strategic cuts at the top plate and at each device box. A Bungalow Heaven 1,400 sq ft rewire typically opens 18 to 30 small access points, not the whole interior. Plaster patching and refinish is part of the scope; full demo is not.
Misconception: The new wiring is the only thing that needs to change.
Reality: A whole-home rewire triggers NEC 210.8 GFCI on every required location, NEC 210.12 AFCI on every habitable-room circuit, NEC 406.12 tamper-resistant receptacles, NEC 314.16 box-fill compliance, and NEC 250.50 grounding electrode update. A rewire that updates wiring without updating these protective devices is incomplete work.
Avoid the partial-rewire-at-discount that leaves K and T in the attic but rewires the basement and first floor. The unpermitted unrewired sections still show up in disclosure, still fail at insurance renewal, and still create a hazard at the splice point where new NM-B meets old K and T. Either commit to the full scope or define a clear phased plan with the AHJ aware.
Decline the cash-no-permit pitch. Whole-home rewires are inspected by LADBS, Pasadena Permit Center, South Pasadena Building Division, or the appropriate AHJ. The permit covers rough-in inspection at the box-and-pull stage and final inspection at trim. Skipping permits forfeits the inspection check, voids future homeowner insurance claims tied to electrical fire, and is non-disclosable at sale.
The smart-panel-with-app at 3,400 to 5,800 dollars on top of the rewire scope is sold as the modern way. Smart panels (Span) have valid use cases on solar-plus-storage homes with battery backup logic, but on a basic rewire-and-200A-service in a Garvanza craftsman with no solar, the premium does not return value. Get the rewire right; layer smart-panel later if the home picks up a battery.
The second upsell is the structured-wiring package (Cat6, coax, fiber to every room) at 2,800 to 4,400 dollars. Many homeowners over-buy data drops they never use. Identify the actual data needs (one wired drop per office, one per AV stack, conduit-only sleeves to future rooms) and build to that, not to a generic structured-wiring spec sheet.
Each review is also emitted in the page JSON-LD with a 1:1 match between visible and structured-data text. Author names use first name and last initial only, and ratings reflect the actual review (some 4-star reviews are included where homeowners flagged a real complaint that was resolved).
Full rewire of a 1912 Craftsman, three weeks of work including coordinating around our home office. Knob-and-tube replaced throughout, plaster patches handled in 18 spots. New Square D QO 200A panel with proper AFCI/GFCI on bedroom and kitchen circuits. Pasadena Permit Center inspections passed at rough and final. The directory is the cleanest I have ever seen. Bungalow Heaven district.
Six Halo H995ICAT recessed cans in the living room ceiling, all on a Lutron Caseta dimmer. The lath and plaster was tricky but they cut clean and used proper old-work brackets. Title 24 Part 6 lighting compliance was handled and the dimmer ramp is smooth, no flicker at the bottom of the curve.
Replaced a 5-ton beast with a properly sized 3.5-ton Carrier Infinity 26 after the load calc came back honest. Title 24 Part 6 §150.2(b) alteration path was followed, HERS rater showed up on schedule, and the duct leakage test passed at the threshold. Crew protected the floors and the new whip and disconnect re-routed off the side-yard fence looks tidy. Whole-house feels more even now.
Older SGV and Northeast LA homes often have connected constraints. A heat pump may need panel capacity, a water-heater change may need venting or electrical work, and an AC leak may be condensate plumbing rather than refrigerant.
No. Booking uses the external scheduler at https://nexfield.pro/crm/book?u=205. The site does not create a fake internal booking form.
Standard dispatch is Monday–Friday 7:00 AM to 7:00 PM and Saturday 8:00 AM to 4:00 PM. After-hours emergency triage available 7 days a week for active leaks, sparking panels, no-cooling, no-heat, and gas-appliance concerns.
License documentation is shared during the booking flow once a scope has been agreed. Inspector-facing paperwork (LADBS, Pasadena Permit Center, LA County Building and Safety) lists the responsible licensed contractor for the specific permit pulled.
Send the symptom, equipment photos, panel photo, shutoff location, access constraints, and urgency. The booking path stays external so there is no fake form and no invented phone number.
