A whole house rewire in metro Atlanta generally runs between $8,000 and $70,000 or more, with most homeowners landing somewhere in the $15,000 to $50,000 range. That is a wide spread, and for good reason. The final price depends on your home’s square footage, how easy it is to reach the wiring inside your walls, the type of old wiring being replaced, and whether your electrical panel needs an upgrade at the same time. Every project is different, so a specific quote from a licensed electrician is the only way to pin down your actual number.
If you own an older home in Lawrenceville, Lilburn, Duluth, Snellville, or anywhere else in Gwinnett County, rewiring is more than a line item on a renovation budget. Many homes in this area were built between the 1960s and 1980s with electrical systems that were perfectly adequate for the era but fall short of what modern households demand. Between central air conditioning running hard through Georgia summers, home offices drawing steady power, and the growing interest in EV chargers, those aging circuits are working harder than they were ever designed to. A rewire brings your home’s electrical system up to current National Electrical Code standards, reduces fire and shock risk, and positions your home for the way you actually live now.
What Determines the Cost to Rewire a House in Metro Atlanta
Several factors push a rewiring estimate up or down. Knowing what they are helps you understand why quotes can vary so much from one home to the next.
Home size is the most obvious driver. A smaller home under 1,500 square feet might cost $8,000 to $20,000 or more to rewire, while a mid-size home between 1,500 and 3,000 square feet typically falls in the $15,000 to $40,000 range. Homes over 3,000 square feet, or projects with unusual complexity, can exceed $35,000 to $70,000. More square footage means more wire, more outlets, more switches, and more labor hours.
Accessibility often matters just as much as size. If your electrician can run new wiring through an unfinished attic or open basement, the work goes faster and costs less. Plaster walls, brick construction, or fully finished basements and attics require more cutting, more careful routing, and more time. Keep in mind that drywall repair and repainting after the electrical work is finished is usually a separate cost billed by a different contractor, not included in your electrician’s quote.
The type of wiring being replaced also affects the price. Homes with aluminum branch circuit wiring, common in some Gwinnett County homes built in the mid-1960s through the mid-1970s, require careful removal because of the known fire risks from expansion and contraction at connections. Knob-and-tube wiring, found in some of metro Atlanta’s oldest homes, presents its own challenges. Both scenarios may add labor time compared to replacing standard copper wiring from a later decade.
Panel upgrades are frequently bundled into a rewiring project. If your home still has a 100-amp panel, your electrician will likely recommend upgrading to 200-amp service so your new wiring has the capacity it needs. That typically adds $2,000 to $4,000 or more to the overall cost, and you can read more about what goes into replacing an electrical panel in our detailed cost breakdown. The number of circuits, outlets, and dedicated lines you need, along with any new fixtures like recessed lighting or ceiling fans, will also move the total.
Finally, local permit fees in Gwinnett County and other metro Atlanta jurisdictions typically run a few hundred dollars but vary by municipality.
Why Older Gwinnett County Homes Are Prime Candidates for Rewiring
Metro Atlanta’s housing boom through the mid-to-late twentieth century left behind a large stock of homes that now sit at the age where electrical systems start to show real wear. A home built in 1975 with its original wiring is pushing fifty years old. The insulation on those wires can become brittle. Connections loosen over time. And the system was sized for a household that probably did not have a microwave, a home theater, multiple computers, and a 4-ton air conditioner all running simultaneously.
Many of these homes also lack safety features that current code now requires. Modern installations include AFCI breakers (which detect dangerous electrical arcing that can start fires) on most living-space circuits, and GFCI outlets (which cut power instantly when they sense a ground fault) in bathrooms, kitchens, garages, and outdoor locations. If your older home does not have these protections, a rewire brings them in across the board. The Electrical Safety Foundation International provides helpful context on older home electrical hazards and why upgrades matter.
Georgia’s storm season adds another layer of urgency. Frequent thunderstorms from spring through fall send power surges through the grid, stressing connections that may already be weakened by age. Proper grounding, a fundamental part of any rewire, gives lightning-induced surges a safe path to earth instead of through your appliances or wiring. If you are unsure whether your home’s wiring has reached the point where replacement makes sense, our guide on signs your Lawrenceville home may need new wires covers the most common warning signals.
What Happens During a Whole House Rewire
Understanding the process helps you plan around the disruption and budget for related expenses.
A licensed electrician starts with an on-site evaluation. They will assess your existing wiring type, panel condition, the number of circuits and outlets you need, and how accessible the wiring paths are inside your walls. Based on that evaluation, you will receive a detailed quote and a scope of work.
Once a permit is pulled through your local building department (required in Georgia for this type of work), the project typically moves through two main phases. The rough-in phase involves running all new wiring through walls, ceilings, and floors, installing new outlet and switch boxes, and setting up the new panel if an upgrade is included. A local inspector visits at this stage to verify everything meets code before the walls are closed up. Then the trim-out phase covers installing outlets, switches, fixtures, and breaker connections. A final inspection confirms everything is safe and code-compliant before the system goes live.
Timelines vary with home size and complexity. Smaller homes may take one to two weeks of electrical work. Mid-size homes often run two to four weeks. Larger or more complex projects can stretch to four to six weeks or longer. During parts of the project, you may be without full electrical power, so plan accordingly.
One important detail: in Georgia, a whole house rewire must be performed by a state-licensed electrical contractor. This is not a gray area or a suggestion. Permits for work this extensive are issued to licensed professionals, and inspections verify the work was done to code. Unpermitted or unlicensed electrical work can void your homeowner’s insurance, create liability when you sell, and, most importantly, put your family at risk.
Repair, Upgrade, or Full Rewire: Choosing the Right Scope
Not every older home needs a complete rewire, and it is worth understanding where your situation falls.
A spot repair makes sense when you have an isolated problem, like a single outlet that has failed or a short section of damaged wire. It is the least expensive option, but it does not address the broader condition of an aging system. Think of it as patching a tire that may need to be replaced entirely.
A panel upgrade increases the amperage and breaker capacity coming into your home. If your existing branch wiring (the wires running through the walls to outlets and fixtures) is still in good condition but your panel cannot keep up with modern demand, a panel upgrade alone may be the right move. However, putting a bigger panel on old, undersized, or deteriorating wiring does not fix the wiring itself. It is like widening a highway on-ramp while leaving the two-lane road unchanged.
A full rewire replaces the branch wiring throughout the house, typically includes a panel upgrade, and brings the entire system up to current code with proper grounding, AFCI, and GFCI protection. It is the most expensive and disruptive option, but it delivers the greatest long-term safety, reliability, and home value benefits. For homes with aluminum branch wiring, knob-and-tube, or extensively degraded insulation, a full rewire is usually the recommendation.
Potential Tax Credits and Ways to Offset the Cost
Rewiring itself is not typically eligible for energy efficiency rebates, but related work done at the same time may qualify. Under the Inflation Reduction Act, a main electrical service panel upgrade that enables the installation of energy-efficient equipment (such as a heat pump or EV charger) may qualify for a federal tax credit of up to 30%, capped at $600 for the panel upgrade component. You can review the current federal tax credits for home energy improvements on the Department of Energy’s website for details and eligibility requirements.
If your rewire includes adding a dedicated 240-volt circuit for a Level 2 EV charger, the charger installation itself may qualify for a separate federal tax credit of up to 30%, capped at $1,000. Georgia Power also periodically offers rebates on specific energy-efficient equipment, so it is worth checking their current residential programs.
These credits and programs change regularly, and eligibility depends on your specific situation. Consult a tax professional before counting on any particular credit amount.
Getting the Right Quote for Your Atlanta Home
A whole house rewire is one of the bigger investments you will make in an older home, but it is also one of the most consequential for safety, comfort, and long-term value. The best way to get an accurate cost is to have a licensed electrician evaluate your specific home, walk through the scope of work with you, and provide a written estimate that covers materials, labor, panel upgrades, permit fees, and any other included items. Ask what is not included (drywall repair, painting, fixture costs) so you can budget for the full picture.

Frequently Asked Questions
How long does a whole house rewire take in an older Atlanta home?
Most whole house rewires in the metro Atlanta area take between one and six weeks of active electrical work, depending on the size of the home and how accessible the wiring paths are. A smaller home with an open attic and unfinished basement might wrap up in one to two weeks, while a larger home with plaster walls or limited access could take four weeks or more. Your electrician should provide a timeline estimate along with your quote.
Do I need a permit to rewire my house in Georgia?
Yes. Georgia requires a permit for whole house rewiring, and the work must be performed by a state-licensed electrical contractor. The local building department will inspect the project at key stages to confirm it meets current code. Skipping the permit can result in fines, insurance complications, and problems if you sell the home later.
Will my walls be damaged during a rewire, and who pays for repairs?
Some wall and ceiling openings are necessary to run new wiring, especially in homes without easy attic or basement access. Your electrician will try to minimize cuts, but some drywall removal is usually unavoidable. In most cases, drywall repair and repainting are handled by a separate contractor and billed separately from the electrical work. Ask your electrician upfront about the expected level of wall access so you can plan and budget for the finish work.
