Whole Home Rewiring Options & Benefits

What Is Whole Home Rewiring?

A whole home rewire replaces branch-circuit wiring, devices, and often the service panel throughout the structure rather than patching isolated areas. In a Phoenix home built before 1975, the work can include removing cloth-insulated or aluminum conductors and installing new copper circuits sized to current code.

The project also updates grounding and bonding, outlet and switch placement, and dedicated circuits for kitchens, laundry, HVAC, and EV charging. Lighting and receptacle circuits can be separated to support modern use and code practice.

We base the design on a load calculation to current National Electrical Code standards. Copper THHN/THWN conductors are sized with Arizona summer ambient-temperature derating in mind, while service planning commonly considers 150 amp or 200 amp capacity for modern demand.

Benefits of Complete Electrical Rewiring

Replacing the electrical system as a coordinated whole addresses hidden wear while aligning circuits, devices, grounding, and panel capacity with how the home is used today.

  • New copper branch circuits replace brittle, cloth-insulated, or aluminum wiring.
  • Grounding and bonding are rebuilt as part of the complete system.
  • AFCI and GFCI protection is installed where current code requires it.
  • Dedicated circuits reduce competition between HVAC, appliances, and EV charging.
  • Outlet, switch, and lighting layouts can be matched to each room's actual use.
  • A permitted installation provides rough-in and final inspection records.
  • Updated wiring can resolve electrical issues flagged during insurance or escrow review.
  • Reserved panel capacity leaves room for solar, a workshop, or future electrical loads.

Finding Your Right Fit

Choosing the Right Rewiring Approach

We compare wire type and gauge, insulation condition, grounding and bonding, panel capacity, wall construction, access, and future loads before recommending a full or targeted scope. That assessment keeps the recommendation tied to the home's actual condition.

Licensed, Bonded & Insured Service

Every technician on our rewiring crews works under our Arizona Registrar of Contractors license. Phoenix Electrician Co. also carries bonding and liability insurance for the work.

Phoenix Heat & Housing Expertise

We plan around Valley conditions and construction, including extreme attic heat, block walls, postwar ranch homes, plaster interiors, mobile homes, condos, and multi-story access challenges.

Permits & Inspection Coordination

We handle the City of Phoenix Development Services Department permit application, scheduling, rough-in inspection, and final inspection for every full rewire, with final sign-off before project closeout.

Brittle, Heat-Damaged Insulation

Long-term attic heat can accelerate insulation breakdown until it cracks and exposes conductors. That creates arc-fault risk inside walls and attics where the damage is difficult to see.

Overheating Aluminum Connections

Aluminum oxidizes at connection points and expands and contracts more than copper under heat cycling. Loose or deteriorated connections can overheat at outlets, switches, and splices.

Ungrounded Knob-and-Tube Wiring

Knob-and-tube wiring lacks a grounding conductor and is not rated for contact with modern attic insulation. Leaving it active can also create obstacles when arranging insurance coverage.

Undersized 60 or 100 Amp Service

Many postwar Phoenix ranch homes were built with 60 or 100 amp service, which may fall short once central air conditioning, appliances, connected devices, and EV charging are included. A load calculation determines the capacity the redesigned system actually needs.

Insurance and Escrow Delays

Aluminum wiring, ungrounded circuits, and active knob-and-tube can be flagged by lenders or insurers during a sale. A documented, permitted rewire with final inspection sign-off can resolve the electrical issue before closing.

Active Arcing Warning Signs

Warm outlet covers, a persistent burning smell, repeated breaker trips, unexplained flickering, or panel scorching can indicate active arcing or overheated connections. These symptoms call for priority troubleshooting and a safety shutoff when the system presents an active hazard.

How It Works

Our Whole Home Rewiring Process

A typical single-story rewire runs one to two weeks through inspection, design, rough-in, device installation, and final approval. Larger, occupied, or multi-story homes can extend to three weeks when access or scheduling requires more phases.

01.

In-Home Electrical Inspection

We inspect panel condition, wire type and gauge, grounding and bonding, and outlet and switch placement room by room. The findings show whether deterioration is isolated or system-wide.

02.

Load Calculation & Circuit Design

We calculate current demand and plan dedicated kitchen, laundry, HVAC, and EV-charging circuits. This step also determines panel amperage and reserved breaker space for future additions.

03.

Written Scope & Permit Application

The free on-site estimate separates labor and material costs in a written scope. We then handle the permit application and inspection scheduling with the City of Phoenix Development Services Department.

04.

Targeted Access & Rough-In

Crews protect floors and furniture, set dust barriers, and route new wiring through attics, crawlspaces, and wall cavities. Small access holes are cut only where needed for outlets, switches, and difficult paths.

05.

Rough Inspection & Device Installation

The rough wiring is inspected before access points are closed. After approval, we install the planned receptacles, switches, fixtures, breakers, and required circuit protection.

06.

Final Inspection & Project Closeout

We coordinate the final inspection, complete daily cleanup, and close out the project after final sign-off. When homeowners remain in the property, work is phased room by room and power is restored to completed areas each evening when practical.

Call About Your Rewire

A complete rewire for a 2,000 square foot Phoenix home generally runs $8,000 to $15,000. Age, block or wood-frame construction, access, finish work, and a 200 amp panel upgrade can move the total within or beyond that range. We provide a written quote after an on-site walkthrough.

Most electricians recommend evaluating wiring once a home passes 40 to 50 years old. Homes built between 1965 and 1973 with aluminum branch wiring may need attention sooner, while pre-1950s homes with active knob-and-tube wiring typically need replacement. An original fuse panel or a home with no known electrical inspection is another reason to schedule an evaluation.

Yes, in most cases. We fish copper wiring through existing wall cavities from attic or crawlspace access and make small openings at outlets, switches, or difficult routes. Plaster interiors, unusual framing, or multi-story construction may require limited removal in specific areas, but full demolition is generally the exception.

Sometimes. If inspection and troubleshooting find isolated faults, options can include a panel upgrade, targeted circuit replacement, dedicated circuits, or added GFCI and AFCI breaker protection. These focused corrections cost less but do not address system-wide wear, so the wiring's overall condition should guide the choice.

Most homeowners stay because work can proceed room by room and power can be restored to completed areas each evening. Larger projects or scopes requiring extended panel downtime may create scheduled periods without power in specific areas. We plan those phases around the household's routine when practical.

Baseline work averages around $2.65 per square foot, while fuller scopes with panel upgrades and drywall repair can run about $5 to $17 per square foot. A 1,000 to 1,500 square foot home may run roughly $6,000 to $10,000. Homes from 2,500 to 3,000 square feet tend toward the upper end of the broader project range or beyond, depending on access and finish work.

A typical single-story rewire takes one to two weeks for demolition and rough-in, rough inspection, devices and fixtures, and final inspection. Larger, occupied, or multi-story homes can take up to three weeks when access and phasing add time. The written scope should identify the expected schedule for the property.

Yes. A full rewire requires a permit through the City of Phoenix Development Services Department, followed by rough-in and final inspections. We handle the application, scheduling, and inspection coordination as part of every full rewire.

Not automatically; the load calculation determines the correct service capacity. Many older Phoenix homes still have 60 or 100 amp service, while modern rewiring plans commonly consider 150 amp or 200 amp panels for HVAC, appliances, EV charging, and future loads. Panel replacement is included only when the planned demand and existing equipment call for it.

Full copper rewiring is the system-wide correction, but an approved copper-pigtail retrofit may be suitable in some homes. We evaluate the wire, devices, splices, oxidation, and signs of overheating before recommending either path. The scope should reflect the condition throughout the home rather than one connection alone.

Warm outlet covers, a persistent burning smell, repeated breaker trips, unexplained flickering, and visible scorching at the panel can indicate arcing or overheated connections. These are not wait-and-see symptoms. We treat active-hazard calls as priority troubleshooting visits and can perform a safety shutoff when needed.

Block construction limits exterior wall cavities, so routing often relies on attic or crawlspace access and fishing conductors down interior walls. Small, targeted openings may be needed at outlets, switches, or difficult transitions. The route is planned to avoid broad wall demolition whenever practical.

Our free on-site estimate includes a walkthrough, load calculation, and review of the wiring, panel, grounding, and room-by-room electrical needs. The written scope separates labor and material costs so you can see what the project includes before work starts. Accessibility, panel needs, device count, finish work, and copper pricing are considered in the total.
