If you’ve ever lain awake wondering whether that flickering light or tripping breaker is a warning sign of something worse hiding inside your walls, you’re not being paranoid — you’re being perceptive. Older wiring, overloaded circuits, and decades of amateur electrical work are among the leading causes of residential fires in Arizona. At FHR Electric, our Whole Home Rewiring Home Electrical Services service exists for one reason: to give Scottsdale and greater Maricopa County homeowners complete, documented, code-compliant peace of mind about every wire, breaker, and connection in their home. Not a patch. Not a band-aid. A real solution.
We serve homeowners across Scottsdale, North Scottsdale, Old Town Scottsdale, Phoenix, North Phoenix, Chandler, Gilbert, Mesa, Tempe, Glendale, and Fountain Hills — and we’ve seen it all. Knob-and-tube wiring tucked inside 1960s ranch walls. Double-tapped breakers crammed into a panel that was already out of breaker slots before the last kitchen remodel. Unpermitted wiring stapled behind new drywall by a handyman who no longer picks up his phone. If any of that sounds familiar, keep reading.
What Whole-Home Rewiring Actually Solves
Most homeowners don’t call an electrician until something stops working. But the real risk isn’t what you can see — it’s what you can’t. Corroded wires in the breaker box, insulation that has cracked and dried after years of Arizona heat, undersized circuits being asked to carry modern loads they were never designed for. These aren’t hypothetical dangers. They’re the hidden electrical fire hazards we find in inspection after inspection across Maricopa County.
A whole-home rewire replaces your existing wiring infrastructure from the panel outward — new copper conductors, updated outlets, modern junction boxes, and properly sized circuits for every room and appliance in your home. When we’re done, your home meets current NEC code, passes inspection, and can actually support your lifestyle: the EV charger in the garage, the new HVAC system, the remodeled kitchen, and the home office running on a whole home surge protector. If you’ve been asking yourself is 100 amp service enough for a modern home? — for most Scottsdale households today, the honest answer is no.
Who This Service Is For
We built this service for homeowners who refuse to cut corners — people who’ve already been burned by an unlicensed sub or a handyman who talked a good game and delivered dangerous work. Here’s who calls us most often:
- Homeowners in older properties — If your home was built before 1990, there’s a real possibility your wiring doesn’t meet today’s safety standards or load requirements. A two prong outlet upgrade is often just the tip of the iceberg.
- High-end remodel clients — Working with a general contractor on a full renovation? We are the electrical contractor for contractors, handling everything from rough-in to final trim so your GC can stay on schedule and on budget.
- EV and Tesla owners — A NEMA 14-50 outlet installation or ChargePoint Home Flex wiring requires a dedicated circuit with correct amperage and proper panel capacity. We do it right, permitted, and inspected.
- Pre-sale and pre-listing homeowners — A pre-listing electrical check that reveals unpermitted work can kill a deal. We help you legalize unpermitted electrical work, pull permits after the fact, and get your home inspection-ready before your Realtor puts up the sign.
- New construction planning clients — Building in North Scottsdale or Fountain Hills? Proper electrical planning in a new build — including camera pre-wire, ceiling fan rough-in wiring, and above-garage suite electrical rough-in — is infinitely easier to do right before the drywall goes up.
- Small business and medical/dental office owners — Your office electrical build-out or food service electrical wiring demands code-compliant circuits, dedicated runs, and zero tolerance for failure. We understand that downtime is liability.
Our Whole-Home Rewiring Services
Full Wiring Replacement
We remove and replace every circuit in your home — bedroom, kitchen, bathroom, garage, and outdoor — with new code-compliant copper wiring. Every circuit is sized correctly for its intended load, and we don’t cut corners on junction boxes, wire stapling, or conduit runs. We fish wire through drywall where walls must stay closed, and we coordinate with your contractor or restoration crew when walls are already open.
Panel Upgrade and Replacement
A rewire without an upgraded panel is like putting new plumbing in a house with a collapsed main line. We assess what size panel you need for your home and lifestyle — whether that’s a 200-amp upgrade or a larger smart electrical panel capable of supporting EV charging, solar retrofit battery storage, and whole-home backup power. We also install panel surge protection and, where applicable, an electrical panel monitoring system so you can track consumption and catch problems early.
Outlet, Switch, and Circuit Upgrades
We upgrade two-prong outlets to grounded three-prong receptacles, install GFCI and AFCI protection where code requires it, add dedicated circuits for AC units, tankless water heaters, spa electrical hookups, and pool light electrical wiring. Every outlet and switch is installed plumb, tight, and finished cleanly — because we know you notice those details.
Smoke Damage and Post-Storm Electrical Inspection
Arizona monsoons are hard on electrical systems, and a smoke damage wiring inspection after any fire — even a small kitchen incident — is essential before turning circuits back on. We use thermal imaging to find hotspots and damaged insulation that aren’t visible to the naked eye. Our post-storm electrical inspection process documents everything so you have a clean report for your insurance company and your own records.
EV Charger and Dedicated Circuit Installation
Whether you need a NEMA 14-50 for a portable charger or a hardwired Level 2 circuit for a ChargePoint Home Flex or Tesla Wall Connector with smart EV charger scheduling, we handle the full scope: panel capacity check, new dedicated circuit, conduit to the garage, and permit. We also handle HOA EV charger installation coordination when your community requires documentation and approval.
Smart Home and Lighting Integration
A rewire is the perfect time to future-proof your home. We rough in for smart lighting systems, add low-voltage wiring for cameras and AV, and create the infrastructure your smart home needs. When you’re ready, explore our indoor lighting installation services to complete the transformation with fixtures that match your style and your electrical system’s new capacity.
Why This Matters More in Arizona
Arizona’s extreme heat accelerates the degradation of wire insulation faster than nearly any other climate in the country. Attic temperatures in Scottsdale can exceed 160°F in summer — and that’s exactly where most of your home’s wiring runs. Insulation that might last 50 years in a mild climate can become brittle and dangerous in 20 to 30 years here. Add in the fact that older Maricopa County homes are being asked to power modern loads they were never designed for — multiple mini-splits, induction cooktops, EV chargers, home offices, whole-home entertainment systems — and the case for a full electrical system upgrade for resale value and daily safety becomes impossible to ignore.
Understanding what whole-home rewiring involves is the first step to making an informed decision about your home’s electrical system. The second step is calling a licensed team that actually does this work every day in your neighborhood.
“We don’t just replace wire. We rebuild the electrical foundation of your home so it’s safe, modern, and ready for whatever your life demands next — not just today, but twenty years from now.”

How We Work — Our Process
We know cost uncertainty and surprise invoices are a real fear on a project this size. Here’s exactly how we handle a whole-home rewire from start to finish so there are no surprises:
- Comprehensive On-Site Assessment — We walk your entire home, inspect the existing panel, photograph corroded wires in the breaker box or any code violations, and use thermal imaging to identify hotspots you can’t see. We document everything.
- Detailed Written Scope and Fixed-Price Proposal — Before any work begins, you receive a written proposal with a clear scope and a price. No vague estimates that balloon later. If we find something unexpected once walls are open, we tell you immediately — we never proceed without your approval.
- Permit Pulling and City Coordination — We pull every required permit with the city or county before work begins. If you have existing unpermitted electrical work that needs to be legalized, we handle that process too — including permit after the fact where applicable.
- Phased Work to Minimize Disruption — We work room by room and keep circuits live wherever possible. For occupied homes, we coordinate daily start/stop times around your schedule. For remodel projects, we coordinate directly with your general contractor.
- Inspection and Sign-Off — Every rewire we complete is inspected by the local authority having jurisdiction and signed off to code. You receive copies of all inspection records.
- Final Walk-Through — We walk you through every new circuit, explain your panel layout, and answer every question before we consider the job complete. You also receive a written electrical map of your home for future reference.
Pair Your Rewire with Whole-Home Backup Power
A rewired home with a modern panel is the ideal foundation for whole-home backup power. Arizona’s grid isn’t immune to outages — monsoons, extreme heat events, and grid stress during peak summer demand are all real. While we’re upgrading your panel, it’s the perfect time to discuss a transfer switch installation and generator or battery backup system. Explore our whole-home backup power options or get into the details with our whole-home automatic backup power systems that kick on within seconds of an outage — with no action required from you. For businesses where downtime is not an option, see our commercial generator installation and maintenance services.
The Cost to Upgrade Electrical Wiring — What to Expect
We get asked about cost constantly, and we respect that. A whole-home rewire is a significant investment — typically in the mid-to-upper range for home improvement projects — but it’s also one of the highest-value things you can do for a Scottsdale home in terms of safety, insurability, and resale value. Homes with documented, permitted electrical upgrades sell faster and for more money in a competitive market. Homes with known wiring defects disclosed at inspection often see price reductions that far exceed what the repair would have cost.
The exact cost depends on your home’s size, the condition of existing wiring, whether walls are open or closed, and any additional work like a panel upgrade or EV circuit. We give you a real number after we see the home — never a range so wide it’s meaningless, and never a lowball number designed to get in the door and then surprise you later.
