Frequently Asked Questions About Electrical Upgrades

Pricing Questions

How much does it cost to rewire a 2000 sq ft house?

Rewire pricing depends on access (attic/crawlspace vs walls open), knob-and-tube or aluminum remediation, panel condition, and finish repairs. A ~2000 sq ft home is not a fixed package price. Every job is different — we provide a custom quote after we see your site. Typical whole-home rewire or major upgrade projects often start around $9,913 in labor (28 hours at our standard rate) before materials, permits, and scope; there is no one-size-fits-all maximum.

How much does it cost to replace aluminum wiring?

Cost tracks how much aluminum is present, access, and whether a panel upgrade is included. Every job is different — we provide a custom quote after we see your site. Typical whole-home rewire or major upgrade projects often start around $9,913 in labor (28 hours at our standard rate) before materials, permits, and scope; there is no one-size-fits-all maximum.

How much does it cost to replace knob-and-tube wiring?

Knob-and-tube replacement is scoped by how much remains active, insulation contact, and access. Every job is different — we provide a custom quote after we see your site. Typical whole-home rewire or major upgrade projects often start around $9,913 in labor (28 hours at our standard rate) before materials, permits, and scope; there is no one-size-fits-all maximum.

Service Questions

Should a 60 or 70 year old house be rewired?

Age alone is not the rule — condition is. Many 60–70 year old your area homes still have original cloth, knob-and-tube, ungrounded circuits, or overloaded panels. If circuits are brittle, ungrounded, aluminum branch wire, or failing inspection/insurance review, a partial or full rewire is often the right long-term fix.

Can a house be rewired without removing all the drywall?

Sometimes. Attic and crawlspace fishing can replace many runs with limited patching. Fully concealed damage, plaster lath, or slab homes may need more opening. We scope the least-invasive path that still meets CEC/NEC and inspection.

How can I tell if my house needs rewiring?

Signs include two-prong ungrounded outlets, warm outlets, frequent trips, lights dimming when appliances start, cloth or knob-and-tube in the attic, aluminum branch circuits, or an insurer/inspector flag. We open accessible areas and give an honest panel-only vs rewire recommendation.

Can I upgrade the panel without a full rewire?

Yes — that is common. Panel upgrades and whole-home rewires are different scopes. We only recommend rewiring when branch circuits are unsafe or inadequate, not as an automatic add-on to every 200A service change.

Should aluminum wiring be replaced?

Aluminum branch-circuit wiring from the 1960s–70s is a known fire-risk concern when connections were not installed with compatible devices. Options include full copper rewire or listed remediation (CO/ALR devices, pigtailing with approved connectors) per manufacturer and CEC/NEC rules. We inspect terminations and recommend the safer path for your home.

Is it okay to buy or sell a house with aluminum wiring?

It is possible, but buyers, insurers, and appraisers often require remediation or a price adjustment. Documented repair by a licensed electrician (and permits when required) makes transactions smoother than leaving unmarked aluminum as-is.

What are signs of bad aluminum wiring?

Warm switch/outlet plates, flickering lights, odd smells at receptacles, aluminum conductors visible in boxes, or breakers that trip under moderate load. Do not ignore heat at terminations — call (657) 239-6331 for diagnosis.

Is knob-and-tube wiring dangerous?

Original knob-and-tube can be hazardous when modified, overloaded, or covered with insulation that traps heat. It also lacks an equipment grounding conductor. Insurers and home inspectors frequently require replacement. We evaluate what is still energized and quote a code-compliant copper system.

Can you get insurance or an FHA loan with knob-and-tube?

Many insurers will not write or renew policies on active knob-and-tube, and FHA/conventional underwriting often flags it. Replacing active K&T with permitted modern wiring is the usual path to clearance.

Is it safe to insulate over knob-and-tube wiring?

Generally no. Covering energized knob-and-tube with insulation can create a heat and fire hazard and is restricted under common CEC/NEC and energy-code practices. De-energize and rewire before insulating those cavities.

What do customers say about electrical upgrades from First Electric?

Process Questions

Can I live in the house during rewiring?

Often yes for phased rewires — we keep critical circuits online when possible and schedule room-by-room outages. Full gut rewires during major remodels are easier when the home is vacant. We plan power phasing with you before opening walls.

How long does a whole-house rewire take?

Smaller targeted rewires may take a few days; whole-home projects often take one to several weeks depending on access and patch scope. Remodel coordination can stretch the calendar. Your custom quote includes a realistic schedule.

Do electrical upgrades require permits?

Yes for panel changes, new circuits, rewires, and most service work under the California Electrical Code. We include permitting when the scope requires it.
