What Is Electrical Rewiring — and When Is It Necessary?

Electrical rewiring is the process of replacing some or all of a home's existing wiring with new, code-compliant copper wiring — including the conductors, junction boxes, outlets, switches, and related components that make up a home's electrical system.

It is not always a full-house project. Rewiring can be targeted — a single room, a specific circuit, or a hazardous wiring type identified during an inspection. In many Fort Worth homes, partial rewiring addresses the highest-risk areas without the cost or disruption of a complete whole-home replacement.

S&M Electric handles electrical wiring and rewiring for homeowners from West Fort Worth to Weatherford — from new circuit additions to full-home rewires — permitted, code-compliant, and guaranteed.

Why Older North Texas Homes Are High Priority

The North Texas area has has a lot housing built between the 1950s and 1980s.

Homes from this era commonly contain one or more of three wiring conditions that create real safety and insurance risk:

Aluminum Wiring (1960s–1970s homes)

Aluminum wiring was widely used during the 1960s and 1970s as a cost-effective alternative to copper. The problem: aluminum expands and contracts more than copper with temperature changes — and DFW attic temperatures regularly exceed 140°F in summer, accelerating this cycle dramatically.

Over time, aluminum connections loosen at outlets, switches, and junction boxes. Loose connections arc. Arcing starts fires — often inside walls where they're invisible until serious damage has already occurred.

Texas insurance companies increasingly require proof of aluminum wiring remediation before issuing or renewing coverage on affected homes. If your home was built between 1965 and 1973, there is a meaningful chance it has aluminum branch circuit wiring.

Knob-and-Tube Wiring (Pre-1940s homes)

Knob-and-tube wiring — found in Fort Worth's older historic neighborhoods — uses individual conductors supported by ceramic knobs and tubes with no ground wire. The original rubber insulation on these conductors dries out, cracks, and eventually exposes live wire inside wall cavities and attic spaces.

Knob-and-tube wiring cannot safely support modern electrical loads. It has no ground wire, providing no protection against fault conditions. Insulation contractors will not insulate attic spaces with active knob-and-tube wiring because the combination is a documented fire hazard.

Undersized or Deteriorated Wiring

Homes that have had additions, remodels, or DIY electrical work over the decades frequently contain undersized wiring, mixed wire gauges, improper splices, and connections that don't meet current National Electrical Code standards. These conditions don't always produce obvious symptoms — until they do.

8 Signs Your Home May Need Rewiring

You don't need to see the wiring to recognize the warning signs:

⚡Breakers that trip repeatedly on circuits under normal household load

⚡Lights that flicker or dim when appliances kick on — especially HVAC or kitchen appliances

⚡Outlets or switches that feel warm, buzz, or spark

⚡Burning smell from outlets, switches, or the panel — treat this as an emergency

⚡Discolored outlet or switch covers — yellowing or browning indicates heat damage

⚡Your home was built before 1980 and has never had a wiring inspection

⚡A home inspector flagged your wiring during a purchase, sale, or insurance review

⚡You're planning a major addition or renovation that adds electrical load to existing circuits

Any one of these warrants a professional assessment. Several of them together warrant immediate action.

Rewiring Options — Full Home vs. Partial vs. Remediation

Not every wiring problem requires rewiring the entire house. Here's how we approach it:

Full Home Rewiring

Complete replacement of all branch circuit wiring, outlets, switches, and junction boxes throughout the home. Typically required for homes with active knob-and-tube wiring, severely deteriorated insulation throughout, or homes undergoing a complete gut renovation.

Full home rewiring in the Fort Worth area typically costs $8,000 to $20,000 depending on home size, construction type, and accessibility. Most projects take 3 to 7 days. We assess your specific home before quoting — square footage alone doesn't determine the number.

Partial or Circuit-Specific Rewiring

Targeted rewiring of specific rooms, circuits, or problem areas — kitchens, bathrooms, garages, additions — without full-home disruption. Often the right solution when problems are localized or when a renovation creates the opportunity to update specific areas while walls are already open.

Aluminum Wiring Remediation

For homes with aluminum branch circuit wiring, full replacement with copper is the most permanent solution. Where budget is a constraint, CPSC-approved remediation using AlumiConn connectors — creating approved copper-to-aluminum connections at every outlet, switch, and junction box — is a recognized alternative that satisfies most Texas insurance underwriters.

AlumiConn remediation typically costs $2,500 to $5,000 for a standard Fort Worth home — significantly less than full rewiring while addressing the primary failure points.

We assess your specific situation and give you honest options with honest costs.

What the Rewiring Process Looks Like

No guesswork. No surprise costs halfway through. Here's what happens from the first call to the final test:

Step 1 — Electrical Assessment

We inspect your current wiring, identify hazardous conditions, assess circuit capacity, and determine the scope of work needed. We tell you what we found and what your options are — not what produces the largest invoice.

Step 2 — Permit Pulled

Rewiring requires permits in Fort Worth. We handle all permitting with the City of Fort Worth or the relevant municipality. Unpermitted rewiring creates liability at resale and may void homeowner's insurance coverage for electrical incidents.

Step 3 — Phased or Full Installation

Depending on scope, rewiring may be completed in phases to minimize disruption — or done completely during a renovation when walls are already open. We coordinate around your schedule and give you a realistic timeline before work begins.

Step 4 — Inspection and Final Testing

All rewiring work is inspected by the local authority having jurisdiction. We coordinate the inspection, make any required adjustments, and test every circuit before we call the job complete.

New Wiring for Additions, Renovations, and Remodels

Rewiring isn't only about fixing old problems. New wiring is also required whenever a home's footprint or

electrical demand grows:

⚡Room additions — new circuits, outlets, and lighting for any added square footage

⚡Kitchen remodels — dedicated circuits for refrigerators, dishwashers, microwaves, and countertop appliances per NEC requirements

⚡Bathroom remodels — GFCI-protected circuits, exhaust fan wiring, vanity lighting

⚡Garage conversions — proper circuits for the new use, whether workshop, living space, or ADU

⚡Home office buildouts — dedicated circuits for computer equipment, monitors, and networking gear that standard household circuits aren't designed to support reliably

If you're planning a renovation and your electrician isn't part of the conversation from the beginning — they should be. Wiring done before walls close is a fraction of the cost of wiring done after.

Electrical Wiring & Rewiring FAQs — Answered Straight

How do I know if my home needs rewiring?

The most reliable answer comes from a professional inspection — especially for homes built before 1980. Observable warning signs include frequently tripped breakers, flickering lights, warm or discolored outlets, burning smells near electrical components, and visible aluminum or cloth-insulated wiring. A home inspector flagging your wiring during a sale or insurance review is another clear signal. When in doubt, an assessment costs nothing and tells you exactly where you stand.

How much does it cost to rewire a house in Fort Worth?

Whole-home rewiring in Fort Worth typically costs $8,000 to $20,000 depending on home size, construction type, and accessibility. Partial rewiring — targeting specific circuits or rooms — typically starts at $1,500 to $4,000. Aluminum wiring remediation using AlumiConn connectors typically runs $2,500 to $5,000 for a standard home. We give you a specific number after assessing your home — not a range designed to manage expectations.

How long does rewiring a house take?

Most whole-home rewiring projects take 3 to 7 days depending on home size, construction type, and whether walls need to be opened. Partial rewiring jobs are typically completed in 1 to 3 days. We give you a realistic timeline during the assessment — not a best-case estimate.

Will rewiring my home require opening the walls?

In most cases, yes — at least partially. Running new wiring through finished walls requires access points that are patched and finished after the work is complete. The extent of wall opening depends on your home's construction, attic accessibility, and the scope of the rewire. We assess access conditions during the estimate and tell you upfront what the installation will involve and what the finished result will look like.

Is aluminum wiring dangerous?

Aluminum branch circuit wiring is a recognized fire hazard due to its tendency to loosen at connection points over time — a problem significantly accelerated by the extreme heat cycles in DFW attics. Homes with aluminum wiring have a documented higher rate of electrical fires than comparable copper-wired homes. However, complete rewiring is not always immediately required. CPSC-approved remediation using AlumiConn connectors at every connection point is a recognized alternative that most Texas insurance underwriters accept. We assess your specific situation and give you honest options.

Can I stay in my home during rewiring?

In most cases, yes — though there will be periods when power to sections of the home is interrupted. We coordinate work schedules to minimize disruption and give you a clear daily picture of what will and won't have power. For full-home rewires, some homeowners choose to stay elsewhere for the duration, especially if the job involves the main service entrance.

Will rewiring my home affect my homeowner's insurance?

Positively — in most cases. Insurance underwriters view updated wiring as reduced risk, and many Texas insurers require proof of remediation for homes with aluminum wiring or knob-and-tube systems before they'll write or renew a policy. We provide documentation of all permitted and inspected work for your insurance file.

Does a home addition require new wiring?

Yes. Any new living space requires new circuits, outlets, lighting, and HVAC connections per current NEC standards. These cannot be safely added by extending existing circuits that were sized for the original footprint. We assess your panel capacity as part of any addition wiring estimate — if the panel needs to be upgraded to support the addition, we identify that upfront.

Concerned About Your Home's Wiring? Start With an Assessment.

You don't have to know whether you need rewiring. That's what the assessment is for.

If your home is older, if an inspector flagged something, if you're seeing warning signs — the right first step is a professional evaluation from a licensed Fort Worth electrician who will tell you the truth about what's there and what it means.
