Rewiring a house is one of those projects that catches many homeowners off guard. You might be renovating an older home, dealing with flickering lights and tripped breakers, or preparing for a home inspection that flagged outdated wiring. Whatever the trigger, understanding the actual costs involved helps you budget realistically and avoid surprises when contractors start opening walls.
What Drives the Cost of a Full House Rewire
Square footage matters, but it's not the only factor. A 1,000-square-foot home typically costs less to rewire than a 2,500-square-foot house simply because there's less wire to run and fewer outlets to install. But the age of your home, the complexity of the layout, and how accessible your walls and attic are can swing costs significantly.
Homes built before the 1970s often have knob-and-tube or aluminum wiring that needs complete replacement, not just upgrades. Two-story homes cost more than single-story ranches because running wire vertically adds labor time. Finished basements, multiple electrical panels, and the need to bring everything up to current code all add to the final bill.
Labor accounts for the majority of rewiring expenses. Licensed electricians typically charge by the hour or by the project scope, and rewiring an entire house is a multi-day job. Expect the electrician to spend time planning the layout, pulling old wire, fishing new wire through walls, installing boxes and outlets, connecting everything to the panel, and testing the entire system before closing up walls.
Breaking Down the Scope of Work
A complete rewire isn't just swapping out a few outlets. The electrician will replace all the wiring from the main panel to every switch, outlet, and fixture in your home. This includes grounding wires, which many older homes lack entirely. Modern electrical codes require GFCI outlets in bathrooms, kitchens, and outdoor areas, and AFCI protection in bedrooms and living spaces.
Your electrical panel might need an upgrade too. If you're moving from a 100-amp service to 200 amps to handle modern appliances and electronics, that's an additional cost. The utility company may need to upgrade the service drop from the street, which involves coordination and sometimes permits that extend the timeline.
Drywall repair is often the hidden expense homeowners forget. Electricians need access to wall cavities, which means cutting holes. While some contractors patch and paint as part of their quote, others expect you to hire a separate crew for finishing work. Clarify this upfront to avoid budget shock.
How Size and Complexity Affect Your Budget
Small homes with straightforward layouts cost less per square foot than sprawling properties with vaulted ceilings and complex room configurations. A compact 1,200-square-foot bungalow with an accessible attic and crawl space is faster to rewire than a multi-level home where every wire run requires cutting into finished walls.
The number of circuits also matters. A basic rewire might include circuits for general lighting, kitchen appliances, bathrooms, HVAC, and a few dedicated lines for electronics. If you're adding a home theater, electric vehicle charger, hot tub, or workshop, each dedicated circuit adds material and labor costs.
Permit fees vary by location but are non-negotiable. Most jurisdictions require permits for whole-house rewiring, and inspections at various stages ensure the work meets code. A reputable electrician pulls permits as part of the job and schedules inspections without you having to chase down the building department.
Red Flags When Hiring an Electrician for This Job
Anyone who offers to skip permits to save you money is waving a red flag. Unpermitted electrical work creates liability nightmares if something goes wrong, and it can derail a future home sale when inspectors discover non-compliant wiring. Insurance companies may deny claims if they learn major electrical work was done without proper permits and inspections.
Vague quotes without a detailed scope are another warning sign. A professional estimate breaks down labor, materials, permit fees, and any additional costs like panel upgrades or drywall repair. If an electrician walks through your house for five minutes and tosses out a number, they're guessing, not estimating.
Ask about licensing and insurance before anyone touches your electrical system. Licensed electricians carry liability insurance and workers' compensation coverage. If an unlicensed handyman gets hurt in your home or causes a fire due to faulty wiring, you could be personally liable.
Questions to Ask Before the Work Begins
Clarify the timeline from start to finish, including how long your power will be off during critical phases. Most electricians can keep sections of your house energized while they work on others, but there will be periods when you'll need to make alternate arrangements.
Ask whether the estimate includes bringing everything up to current electrical code or just replacing existing wiring as-is. Code upgrades often cost more but are required in most jurisdictions for whole-house rewires. You want GFCI and AFCI protection, proper grounding, and sufficient circuits to handle modern electrical loads safely.
Find out who handles the drywall repair and repainting. Some electricians include basic patching in their quotes, while others leave you with open walls and a list of recommendations for finish contractors. Knowing this before signing a contract prevents unpleasant surprises when you're standing in a house full of holes.
Finding the Right Electrician for Your Rewiring Project
Major electrical work isn't the place to gamble on the lowest bidder. You want a licensed professional with specific experience in whole-house rewiring, not just someone who installs ceiling fans on weekends. Check that their license is current, verify their insurance coverage, and ask for references from similar projects.
Getting multiple quotes helps you understand what's fair for your market and home size. Detailed estimates from three different electricians give you comparison points for both price and scope. If one bid is dramatically lower, dig into what they might be leaving out rather than assuming you've found a bargain.
