What to Expect During a Whole-Home Rewire

Is It Time to Rewire Your Home?Many homes built before the 1980s weren't designed to handle today's electrical demands. Between smart home technology, home offices, electric vehicles, large appliances, and entertainment systems, modern families use significantly more electricity than homeowners did decades ago.
If your home has outdated wiring, a whole-home rewire may be the safest and most cost-effective solution.
Common signs include:

• Frequently tripped breakers
• Flickering or dimming lights
• Two-prong outlets
• Warm or discolored outlets
• Aluminum wiring
• Knob-and-tube wiring
• Burning smells near outlets or switches
• Lack of GFCI or AFCI protection
• Limited outlets requiring multiple extension cords

Step 1: A Complete Electrical Inspection. Every whole-home rewire begins with a comprehensive electrical inspection.
An ECO Electric licensed electrician will evaluate:

• Existing wiring condition
• Electrical panel capacity
• Grounding and bonding
• Outlet and switch placement
• Lighting circuits
• Safety concerns
• Code compliance
• Future electrical needs

This inspection helps create a customized plan based on your home's layout and your family's lifestyle.
Step 2: Planning Your New Electrical System. A rewire is the perfect opportunity to upgrade your home's electrical capabilities.
Many homeowners choose to add:

• More outlets throughout the home
• USB and USB-C charging outlets
• Dedicated circuits for home offices
• EV charger circuits
• Whole-home surge protection
• Smart switches and dimmers
• Under-cabinet lighting
• Outdoor lighting circuits
• Ceiling fan wiring
• Generator connections

Planning these upgrades now is much easier than adding them later.
Step 3: Obtaining Permits. Electrical rewiring requires permits and inspections to ensure everything meets local and National Electrical Code (NEC) requirements.
ECO Electric handles:

• Permit applications
• Required inspections
• Code compliance
• Final approvals

Homeowners don't have to navigate the permitting process alone.
Step 4: Removing Old WiringDepending on the home's construction, electricians will remove or disconnect old wiring and begin installing new wiring throughout the home.
Some existing wiring may remain inside walls if removal would cause unnecessary damage, but it is permanently disconnected and replaced with new wiring.
Step 5: Installing New Wiring. This is the largest portion of the project.
New wiring is carefully routed through:

• Walls
• Ceilings
• Attics
• Crawl spaces
• Basements

Electricians install:

• Modern copper wiring
• New outlets
• New switches
• Junction boxes
• Grounding systems
• Smoke detector wiring
• Dedicated appliance circuits

Every circuit is labeled for easier maintenance in the future.
Step 6: Upgrading the Electrical Panel (If Needed). Many rewiring projects include an electrical panel upgrade.
Older 100-amp panels often struggle to support today's electrical needs.
A panel upgrade may provide:

• Increased capacity
• Additional breaker space
• Improved safety
• Better reliability
• Support for future additions

This is especially important if you're planning to install an EV charger, hot tub, workshop equipment, or backup generator.
Step 7: Testing Every Circuit. Before power is fully restored, every circuit is thoroughly tested.
Electricians verify:

• Proper voltage
• Correct grounding
• GFCI protection
• AFCI protection
• Breaker operation
• Outlet polarity
• Switch functionality
• Lighting operation

Nothing is left to chance.
Step 8: Final Inspection Once installation is complete, the local electrical inspector performs the required inspection.
After approval, your new electrical system is officially ready for everyday use.
How Long Does a Whole-Home Rewire Take? The timeline depends on several factors:

• Home size
• Accessibility
• Age of the home
• Existing wiring condition
• Number of electrical upgrades
• Whether walls are open during remodeling

Most residential rewiring projects take 3 to 10 days, while larger or more complex homes may take longer.
Will My Walls Be Damaged? Some drywall access is usually necessary.
However, experienced electricians work carefully to minimize disruption by using existing access points whenever possible.
If you're planning a remodel, completing the rewire before drywall repairs and painting can save both time and money.
Can I Stay in My Home During the Rewire? In many cases, yes.
Depending on the scope of the work, power may be temporarily shut off to certain areas while new wiring is installed.
For larger projects, some homeowners choose to stay elsewhere for a few days to reduce inconvenience.
ECO Electric will explain what to expect before work begins.
