A whole-house rewire in a typical metro Atlanta home usually takes somewhere between one and four weeks of working time. A smaller two or three bedroom house with an open attic and a crawlspace often lands near the short end of that range, while a larger two-story home with plaster walls, finished ceilings, or tight framing can run to the long end or past it. Permits and inspections add days on top of the work itself, and every house has its own surprises once the walls start telling their story.
That range matters because a rewire is not a weekend project, and most families plan to keep living in the house while it happens. If you own one of the many Gwinnett, DeKalb, or north Fulton homes built between the 1960s and the 1980s, the original wiring was sized for a household with far fewer appliances, no home office full of electronics, and air conditioning that did not run from May to October. Knowing how the schedule actually unfolds helps you decide when to start, which rooms to clear first, and how much disruption to expect before you ever sign anything.
Four Factors Decide Whether Your Rewire Takes One Week or Four
House size is the obvious starting point. More square footage means more circuits, more receptacles, more switches, and more feet of cable to run. As a general rule of thumb, homes around 1,000 to 1,500 square feet often take one to two weeks, homes between 1,500 and 2,500 square feet often take two to three weeks, and larger homes can take three to four weeks or more. Those are broad, typical ranges, not promises, and the next three factors can move any home up or down.
Access is the second factor and often the biggest one. A walkable attic above the top floor and a crawlspace or unfinished basement below the main floor give an electrician clear paths to drop new cable into walls with small openings. Low attic clearance, heavy blown-in insulation, finished basements, and cathedral ceilings all slow the work because each run takes more careful fishing and more openings in finished surfaces.
Wall material is the third factor. Drywall cuts cleanly and patches easily. Plaster and lath, which shows up in older intown Atlanta homes and some early suburban houses, is harder to cut without cracking and takes more time around every box. Homeowners handling electrical rewiring in Atlanta in older neighborhoods should expect plaster to stretch the schedule compared with a 1980s drywall house of the same size.
The fourth factor is what the electrician finds. Knob-and-tube wiring buried in insulation, aluminum branch circuits from the mid-1960s to mid-1970s, spliced connections without junction boxes, and old additions wired by a previous owner all add time. So does a service panel that cannot support the new circuits. If you want the dollars side of these same factors, our guide to house rewiring costs in Atlanta covers pricing drivers, so this article sticks to time and disruption.
What Happens Room by Room During a Phased Rewire
Most occupied homes are rewired in phases rather than all at once. The electrician isolates one area, runs new circuits there, and brings those circuits back to the panel while the rest of the house stays powered. Phasing stretches the calendar a little compared with shutting down the whole house, but it lets you keep the refrigerator cold, the air conditioning running, and the kids sleeping in their own beds. Families planning rewiring in Peachtree Corners and nearby neighborhoods often choose this approach for exactly that reason.
Kitchen and Laundry
Kitchens usually take the most time per square foot. Current code calls for multiple dedicated 20-amp small-appliance circuits on the counters, ground-fault protection at countertop receptacles, and separate circuits for appliances like the dishwasher, disposal, and microwave. Expect a kitchen to be partly out of service for a few days. Laundry rooms follow a similar pattern with a dedicated 20-amp laundry circuit and a correctly rated dryer receptacle.
Bathrooms
Bathrooms need ground-fault circuit interrupter protection, known as GFCI, which cuts power in a fraction of a second if current leaks through water or a person. A bathroom is small but detailed, and it often takes a day or so depending on access above the ceiling and whether an exhaust fan or new lighting is part of the plan.
Bedrooms and Living Areas
Bedrooms, living rooms, and hallways are usually the fastest rooms to finish when attic access is good. These spaces need arc-fault circuit interrupter protection, known as AFCI, which detects dangerous arcing in damaged cords or loose connections and shuts the circuit off before it can start a fire. Many rewires tackle bedrooms as a group so the family can shift into a guest room or living room for a night or two.
Basement, Garage, and Exterior
Unfinished basements and garages are often quick because the framing is open. Garages and exterior receptacles need GFCI protection and weather-resistant devices outdoors. If an EV charger or a dedicated workshop circuit is on your wish list, adding it during the rewire is far easier than coming back later.
The Panel Comes Last or First
The service panel is where every new circuit lands. In many older homes it makes sense to replace a 60-amp or 100-amp panel early so new circuits have somewhere safe to go. Coordinating a panel or service change with Georgia Power or your local electric cooperative adds its own scheduling step, and our electrical panel upgrade team plans that step into the overall sequence so you are not without power longer than necessary.
Permits and Inspections Add Days You Should Plan For
In Georgia, a whole-house rewire requires an electrical permit from your local building department, and the work must be performed by a state-licensed electrical contractor. In Gwinnett County that means the county’s planning and development department for unincorporated areas, while some cities inside the county handle their own permits, so check with the city first if you live inside city limits. This is general information, not legal advice, and your jurisdiction’s current rules are what count.
Rewires typically involve at least two inspections. The rough-in inspection happens after new cable is run but before walls and ceilings are closed. The final inspection happens after devices, covers, and the panel work are complete. Walls cannot be patched over new wiring until rough-in is approved, so inspector availability can create a few days where the crew is waiting rather than working. Requirements come from the adopted edition of the NFPA 70 National Electrical Code, plus any local amendments.
Before a rewire is even scheduled, a thorough evaluation of the current system is worth the time. A professional home electrical inspection documents what wiring types are present, which circuits are overloaded, and whether a partial or full rewire makes more sense. Homeowners around Dunwoody who are weighing rewiring in Dunwoody often find that inspection report is what turns a vague worry into a clear plan with realistic timing.
Living in the House While the Wiring Changes
Staying in the home during a rewire is usually possible, but it helps to go in with clear expectations. There will be planned outages in specific rooms, some noise from drilling, and dust near every opening. The crew needs clear access to walls, so furniture gets pulled away from exterior and interior walls in the active area. Covering electronics, moving valuables, and clearing a path to the attic hatch and panel before day one saves real time.
Plan around the Georgia calendar too. An attic in July can be brutal, which slows any work up there, and summer air conditioning load makes it harder to schedule long outages on the circuits that serve cooling equipment. Many homeowners find spring and fall the most comfortable seasons for a rewire. Thunderstorm season is also a reminder that a new, properly grounded system is a good moment to consider surge protection at the panel.
The work that follows the electrician matters for your calendar as well. New wiring means small openings in walls and ceilings, and patching and painting those openings is typically handled by a separate contractor or by the homeowner once the final inspection passes. Build that step into your schedule so the project does not feel unfinished longer than it needs to.

Age is one of the strongest clues. Our look at how housing age affects electrical reliability in metro Atlanta explains why homes from certain decades show the same patterns of tripped breakers, warm outlets, and ungrounded receptacles. According to NFPA research on home electrical fires, electrical distribution and lighting equipment is a leading factor in home fires, which is why deteriorated wiring deserves attention before it becomes an emergency.
A Realistic Rewire Plan Starts With a Walkthrough
The honest answer to how long your rewire will take comes from someone standing in your attic, opening your panel, and looking at how your walls are built. General ranges help you plan, but the right sequence for your family depends on which rooms you can live without, when inspectors are available, and what is hiding behind the plaster or drywall. Ask any contractor to explain the phase order, the expected outage windows, and when each inspection will happen.

Frequently Asked Questions
Can my family stay in the house during a whole-house rewire?
Usually, yes. Most occupied homes are rewired in phases, one area at a time, so the rest of the house keeps power. Expect planned outages in the rooms being worked on, some dust and noise, and furniture pulled away from walls in the active area.
What is the difference between a partial rewire and a full rewire?
A partial rewire replaces wiring in specific areas, such as a kitchen, an addition, or circuits with known problems. A full rewire replaces the branch circuit wiring, devices, and often the panel throughout the home. An electrical inspection is the best way to decide which one your house actually needs.
Will rewiring mean tearing open all my walls and ceilings?
No. Electricians work through attics, crawlspaces, and basements whenever possible and cut small, targeted openings where cable has to pass through finished surfaces. The number of openings depends on access and wall type, and plaster walls generally need more care than drywall.
How long do electrical inspections add to a rewire in metro Atlanta?
Rewires typically need a rough-in inspection before walls are closed and a final inspection at the end. Scheduling depends on your local building department, so inspections can add a few days to the overall timeline. Your contractor should build those waiting periods into the plan.
Will my home get GFCI and AFCI protection after a rewire?
A rewire brings new circuits up to the code edition your jurisdiction has adopted. That typically means GFCI protection in kitchens, bathrooms, garages, laundry areas, and outdoors, and AFCI protection on most living-area circuits. Your electrician will explain exactly which protection each circuit receives.
