Old wiring does not age gracefully. If you are pricing the cost to replace old electrical wiring in an old house, you are likely seeing flickering lights, warm outlets, tripping breakers, or aluminum or cloth‑insulated wires in the attic. This guide explains realistic DFW pricing ranges, what drives costs up or down, and how Blue Line Electric helps you budget, phase work, and finish safely with clear documentation. Free in‑person estimates and financing available.
What Does Whole‑Home Rewiring Cost in DFW?
Pricing depends on home size, access, and the type of existing wiring. For a typical North Texas single‑family home, you can expect ballpark ranges below. Your in‑person assessment will tighten these numbers.
- 1,200–1,600 sq ft, single story with good access: $12,000–$18,000
- 1,700–2,200 sq ft, single story or smaller two story: $18,000–$28,000
- 2,300–3,000 sq ft, two story or with limited access: $28,000–$45,000+
These ranges generally include new copper branch circuits, new receptacles and switches, GFCI/AFCI protection as required by current code, labeling, permit handling, and circuit testing. Panel replacement, service upgrades, and specialty circuits are additional if needed. Blue Line Electric provides upfront pricing, so there are no surprises.
Key Cost Drivers You Should Know
Understanding what drives cost helps you control it:
- Access and surfaces
- Attic clearance, insulation depth, and safe working platforms
- Plaster walls, tiled backsplashes, or extensive drywall patching
- Existing wiring type
- Knob‑and‑tube or cloth‑insulated requires careful removal and new home runs
- Aluminum branch circuits need remediations or full copper replacement
- Panel and service capacity
- A full panel might be managed with load‑sharing solutions
- True capacity shortages may require a new panel and service upgrade
- Home complexity
- Two‑story runs, vaulted ceilings, additions, and detached structures add time
- Specialty circuits and safety upgrades
- EV chargers, generators, surge protection, and outdoor circuits add line items
Blue Line Electric often reduces cost by using load management when possible, so you only replace a panel when it is the right call, not by default.
Signs Your Old Wiring Needs Attention Now
Rewiring is not only about modern convenience. It is about safety and insurance compliance.
- Warm or discolored outlets and switches
- Frequent breaker trips or fuses blowing
- Aluminum or cloth‑insulated conductors in attics or device boxes
- Two‑prong receptacles and lack of grounding
- Lights dim when appliances start
- Outlets near sinks without GFCI protection
In older parts of Plano, Richardson, and Garland, homes from the late 1960s to mid‑1970s often have aluminum branch circuits. Around Lake Lewisville and other lakeside communities, humidity can accelerate corrosion at outdoor boxes and docks. Local realities matter, and our team sees them every week.
Aluminum Wiring: Full Rewire or Device‑Level Remediation?
You typically have two proven options:
- Full copper rewiring
- Highest safety margin and long‑term value
- Eliminates mixed metal connections
- Device‑level remediation
- Systematic replacement of all devices with aluminum‑rated components
- Proper antioxidant treatment and torque at every connection
We explain both options, document what we find, and help you choose what fits your goals and budget. Many homeowners phase work, starting with kitchens, baths, and high‑load circuits, then completing bedrooms and living areas later.
What Is Included in a Professional Rewire
Blue Line Electric follows a clear process so you know what to expect and what you are paying for.
- Inspection and load analysis
- We map circuits, check conductor types, test grounding, and assess the panel
- Plan and pricing
- You get an itemized scope with phased options when helpful
- Execute with minimal disruption
- We protect floors, mark cut points, pull new copper, and make clean, labeled terminations
- Test and verify
- Every circuit, device, and GFCI/AFCI function is tested and documented
- Walk‑through and documentation
- We show you what changed, deliver labels, and file permits and inspection results
All work is backed by our standard 5‑year workmanship warranty. Our Texas Electrical Contractor license is TECL #24911, and projects are led by a Master Electrician.
Do You Always Need a New Electrical Panel?
Not always. A panel that is full is not the same as a panel that is overloaded. During our assessment we look for these right‑sized solutions:
- Load‑sharing controls for EV chargers and other large loads
- Consolidating circuits with correct arc‑fault protection where allowed
- Using tandem breakers only where the panel labeling permits
If a true capacity shortfall exists or the panel is obsolete, we quote a replacement. When we upgrade panels, homeowners often add whole‑home surge protection at the same time to protect sensitive electronics and HVAC boards.
How Long Will a Rewire Take?
Most single‑story homes take 3 to 7 working days. Two‑story and complex homes can take 1 to 2 weeks. Phased projects spread work over months to ease disruption and cash flow. We keep you powered in key rooms whenever possible, and we schedule noisy or dusty tasks around your routine. At the finish line, expect a clean home, labeled panel, and a walkthrough so you understand every change.
Cost‑Saving Strategies That Still Meet Code
You can control cost without cutting corners.
- Prioritize high‑risk areas first: kitchens, bathrooms, laundry, and GFCI zones
- Combine projects: add surge protection or EV charger wiring while walls are open
- Choose device‑level aluminum remediation now, and plan a future full rewire
- Use financing for larger scopes so safety upgrades do not wait
- Limit surface damage by selecting routes with the least patchwork
Our proposals present options side by side, including phased schedules that let you move ahead safely today.
What Blue Line Electric Does Differently
Rewiring is intrusive. Our job is to make it predictable and professional.
- Upfront pricing with no hidden fees and written scopes

We never default to the most expensive solution. We recommend what your system actually needs, backed by our 5‑year workmanship warranty.

Permits, Inspections, and Insurance Considerations
- Permits and inspections are included in our scope. We coordinate with your city.
- Many insurers flag aluminum and cloth‑insulated wiring. Rewiring often reduces risk and can help with coverage.
- We provide documentation of materials, protections installed, and panel labeling for your records.
Safety Upgrades to Add While Walls Are Open
Take advantage of open access to future‑proof your home:
- Whole‑home surge protection at the panel
- GFCI protection for kitchens, baths, garages, and outdoors
- AFCI protection on living area circuits per current code
- Dedicated circuits for microwave, fridge, garage freezer, and home office
- EV charger circuit or load‑sharing configuration
- Generator interlock or transfer switch
These upgrades add small incremental cost now and save large future labor.
How We Minimize Disruption in Older Homes
Old houses deserve careful work.
- Clean dust control and floor protection
- Thoughtful routing to reduce drywall repair
- Daily cleanup and progress check‑ins
- Respect for historic trim and finishes
At completion, we label the panel, test every device, and walk you through what changed and why.
Transparent Pricing and Documentation You Can Trust
You receive a written, line‑item proposal, clear allowance for patching and permits, and a final invoice that matches the scope. After testing every circuit, we leave a simple one‑page summary of protections installed and any recommended future phases. It is honest work, done right, and backed by our 5‑year workmanship warranty.

Frequently Asked Questions
How much does it cost to replace old wiring in a 1,500 sq ft house?
Expect $12,000–$22,000 in DFW, depending on access, panel needs, and whether aluminum or cloth wiring is present. A free in‑person assessment provides a precise quote.
Do I need to replace my electrical panel during a rewire?
Not always. If the panel is safe and capacity can be managed with load‑sharing solutions, we keep it. If it is obsolete or undersized, we price a replacement.
Can a whole‑home rewire be done in phases to manage cost?
Yes. Many homeowners start with kitchens, baths, laundry, and key living areas, then complete bedrooms and common areas later. Phasing reduces disruption and spreads cost.
What upgrades should I add during a rewire?
Common adds include whole‑home surge protection, AFCI/GFCI coverage, grounding improvements, dedicated appliance circuits, EV charger wiring, and a generator interlock or transfer switch.
How long does a typical rewire take?
Most single‑story homes finish in 3–7 working days. Two‑story or complex layouts can take 1–2 weeks. Your proposal will include a realistic timeline.
