What this service does
Older wiring and modern daily life do not always work well together. A whole-home or partial rewire replaces selected circuits, updates device locations, and builds a coordinated electrical system around the way your household uses power. The right scope starts with the condition of the existing wiring—not simply the age of the house.
What affects the cost
- Home size and number of rooms affected
- Attic, crawlspace and wall access
- Plaster versus drywall
- Whether the panel also needs work
- Permit requirements
No single range is published for this work; True gives a project-specific estimate after understanding your home.
Estimated pricing helps you plan. Your project’s cost depends on the existing electrical system, access, equipment, and scope. We’ll explain the work and pricing before getting started.

Estimated prices for specific jobs
Before tax and permit or utility fees. Hourly labor is not a total project price. Full price list.
Complete rewire, vacant / open-wall remodel$16,200–$31,500 per 1500–2000 sq ft home
Replace branch wiring, standard devices and required branch protection throughout an accessible home.
Open walls or excellent access. Panel replacement, luxury lighting, low voltage and finish restoration excluded.
Complete rewire, occupied / phased$22,500–$45,000 per 1500–2000 sq ft home
Replace branch wiring while staging outages and access around an occupied household.
Finished walls and multiple phases. Panel replacement and patching/painting excluded.
Knob-and-tube inspection and active tracing$315–$810 per assessment
Determine which accessible old wiring remains energized and map affected areas.
Typical 2–4 hours. Concealed conditions can require further investigation. No rewiring included.
Knob-and-tube replacement, attic / crawlspace$1,080–$2,250 per circuit
Replace one accessible old branch circuit with grounded cable and modern terminations.
Approximately 4–8 served points and 50–100 ft. Extensive shared circuits may need a larger scope.
Knob-and-tube replacement, finished areas$1,620–$3,600 per circuit
Fish new grounded wiring to replace an old circuit through finished living spaces.
Approximately 4–8 served points. Access openings may be necessary; repairs excluded.
Aluminum branch-wiring evaluation$315–$720 per assessment
Inspect representative accessible aluminum terminations and define a repair scope.
Assessment only, not inspection of every concealed connection or whole-home remediation.
Aluminum branch-wiring connection remediation$81–$162 per device box in batch
Assess accessible aluminum branch-circuit connections and scope a compatible repair or replacement approach.
Priced per accessible device box in a batch, not per connector. The actual method, connector compatibility and any specialist requirements must be confirmed before quoting. No proprietary repair method is promised.
Ungrounded cloth-jacketed branch circuit replacement$1,080–$2,700 per circuit
Replace an ungrounded branch circuit with new grounded cable and required devices/protection.
Approximately 4–8 points. Cloth covering alone does not establish the wiring condition.
Equipment grounding conductor retrofit$270–$630 per outlet location
Add a permitted equipment grounding path to an existing serviceable circuit location.
Approximately 25–50 ft accessible routing. Full circuit replacement may be more practical.
Junction-box discovery and splice enclosure$315–$810 per small repair visit
Trace a suspect splice, expose it where practical and install accessible electrical enclosures.
One or two accessible repair locations. Broad attic tracing and finish repairs extra.
Open splice remediation$112.50–$270 per splice location in batch
Enclose an exposed splice in a suitable accessible box and correct connections.
Batch pricing. A single-location visit generally carries a $250–$400 minimum.
Abandoned wiring tracing and removal$360–$1,080 per small project
Verify wiring is inactive, disconnect it safely and remove accessible abandoned sections.
Typical half-day scope. Concealed demolition and hazardous-material work excluded.
Common options and scope
Complete and partial rewires
Plan replacement circuits room by room, including living spaces, bedrooms, kitchens, bathrooms, attics, basements, and crawlspaces. Partial rewiring can target damaged wiring or a remodel without assuming every circuit needs replacement.
Knob-and-tube wiring
Assess active knob-and-tube circuits, identify what they supply, and plan their replacement with modern wiring. Insulation, inaccessible splices, shared circuits, and previous alterations affect the approach.
Aging and ungrounded wiring
Assess brittle insulation, obsolete cable and ungrounded circuits to plan appropriate replacement.
Grounding and circuit organization
Address grounding and bonding, accessible junction boxes, circuit identification, outlet placement, and appropriate GFCI/AFCI protection as part of the agreed design.
What happens during the work
Access above and below rooms, finished-wall restoration, occupied-home scheduling, outage windows, panel capacity, and inspection stages all influence the project. Confirm who handles drywall, paint, insulation, and other non-electrical restoration in the proposal.
Helpful to have ready
A short description, your city or ZIP, and photos of the visible area or equipment. Never remove electrical covers or touch exposed wiring for a photo.
Questions
Can I live in my home during a rewire?
Sometimes. Phased work may keep portions of the home usable, but planned outages and access restrictions are unavoidable. The schedule depends on the condition of the existing system and the agreed work sequence.
