Electrical Rewiring Cost: What Texas Homeowners Pay

Rewiring a home is one of the most disruptive but necessary home improvements you can make — particularly in older Texas homes with aluminum wiring, outdated knob-and-tube circuits, or insufficient capacity for modern electrical loads. Understanding what rewiring costs and what drives those costs helps you budget accurately and evaluate contractor quotes.

Average House Rewiring Cost in Texas

Home Size	Partial Rewire	Full Rewire
Under 1,000 sq ft	$2,500–$6,000	$6,000–$12,000
1,000–2,000 sq ft	$3,500–$8,000	$8,000–$16,000
2,000–3,000 sq ft	$5,000–$12,000	$12,000–$25,000
3,000+ sq ft	$8,000–$15,000	$20,000–$40,000+

What “full rewire” means: Removing all existing wiring and installing new circuits throughout the home, including new wiring to all outlets, switches, lighting, and appliances — plus a new main electrical panel if not recently updated.

What “partial rewire” means: Addressing specific problem areas — updating circuits to a kitchen, adding capacity to a workshop, replacing aluminum branch wiring in select areas, or upgrading specific circuits to accommodate new HVAC equipment.

What Drives the Cost of Rewiring in Texas

Home size and number of circuits: More circuits = more time and material. A 2,500 sq ft home may have 30–50 circuits; a 1,000 sq ft older home may have 10–20.

Accessibility: Rewiring a home with open attic and accessible crawl space costs less than rewiring a home with finished ceilings, no attic access, or concrete slab with no crawl space. Much of rewiring cost is fishing wire through walls — homes with limited access require more drywall cutting and patching.

Panel size and condition: If you’re rewiring the home, you’re almost certainly upgrading the panel simultaneously. Panel upgrades from 100-amp to 200-amp service: $1,500–$3,500 (parts + labor + permit). Upgrading to 400-amp service (for large homes, EV charging, whole-home generators): $3,000–$6,000+.

Permit and inspection fees: Texas electrical work requires permits in most jurisdictions. Permit costs vary by city/county — typically $100–$500 for a rewiring project. Inspections are required at rough-in and final. Your electrician should be responsible for permitting and coordinating inspections.

Material costs: Copper wire pricing fluctuates significantly with commodity markets. Current copper wire costs have stabilized but remain elevated compared to pre-2021 levels. Your electrician’s material quote reflects current market pricing.

When Rewiring Is Necessary in Texas

Aluminum wiring (built 1965–1973): Many Texas homes built during this era used aluminum wiring for branch circuits (not just service entrance). Aluminum branch wiring creates fire hazards at connections that expand and contract differently than copper. Options: full copper rewire, or COPALUM crimp repair at every connection point (labor-intensive but less invasive than rewiring).

Knob-and-tube wiring (pre-1945 Texas homes): The uninsulated wiring system used in early Texas construction — particularly in older neighborhoods of Houston, Dallas, San Antonio, and Fort Worth. Brittle, without ground circuits, and fire hazard when covered with blown-in insulation. Full replacement required.

Insufficient amperage for modern loads: A 60-amp or 100-amp service panel is inadequate for a modern Texas home with central HVAC, electric water heater, EV charger, and modern appliances. 200-amp minimum is the standard recommendation; 400-amp for larger homes or homes with multiple HVAC systems.

Frequently tripping breakers: If you regularly trip circuit breakers running normal household loads, your circuits are undersized for current demand.

Planning an addition or major renovation: Any new addition triggers electrical permits and inspections — often the ideal time to address deficiencies in the rest of the home’s electrical system.

Partial Rewire Scenarios

Not every home needs a complete rewire. Common partial rewire projects in Texas:

Kitchen upgrade: Modernizing an older kitchen requires dedicated circuits for microwave, dishwasher, refrigerator, and multiple small appliance circuits on 20-amp circuits. Adding GFCI protection throughout. Cost: $1,500–$4,000.

Bathroom GFCI upgrade: Older Texas bathrooms often lack GFCI protection. Adding GFCI outlets at all bathroom and exterior locations: $300–$800.

EV charger circuit: Adding a dedicated 240V/50A circuit for Level 2 EV charging: $400–$900 from the panel to the garage.

Home office upgrade: Adding circuits and data wiring for a dedicated home office: $800–$2,500 depending on scope.

Finding a Licensed Texas Electrician

All electrical work in Texas requires a licensed electrician — either a Master Electrician or a Journeyman Electrician working under a Master. The Texas Department of Licensing and Regulation (TDLR) maintains the electrician license database.

Get 3 quotes for any significant electrical project. Verify license status at tdlr.texas.gov before hiring. Ask whether the contractor will pull permits — any legitimate electrician pulls permits for required work.

Frequently Asked Questions

How do I know if my Texas home has aluminum wiring?

Check your electrical panel — aluminum wiring is often labeled “AL” on the panel or visible as silver-colored wire (copper is red-orange). In homes built between 1965–1973, aluminum branch circuit wiring is common. A licensed electrician can visually inspect your panel and a sample of outlets to determine wiring type. TDLR-licensed Texas electricians perform aluminum wiring inspections regularly.

Is rewiring a house worth it before selling in Texas?

In many cases, yes — particularly if the home has aluminum wiring or a documented panel issue. These are inspection findings that cause buyers to request large credits or walk away entirely. Proactively rewiring or providing a COPALUM certification eliminates the negotiation point and can allow a cleaner sale. Your real estate agent and an electrician can assess whether the investment makes sense in your specific market.

How long does it take to rewire a house in Texas?

A full rewire of a 2,000 sq ft Texas home typically takes 3–7 days with an experienced crew of 2–3 electricians. Larger homes or homes with more limited access (no attic access, concrete slab) take longer. Plan for significant disruption — walls are opened and patched, power may be off for portions of each day.

Do I need a permit to rewire my Texas house?

Yes. Electrical rewiring requires permits and inspections from your local building authority in virtually all Texas jurisdictions. Licensed electricians include permit costs in their bids and coordinate the inspection process. Work done without permits creates insurance, liability, and resale issues — never agree to “skip the permit” to save money.
