  Typical costs:
  • Copper wire is increasingly expensive, so just the materials alone for rewiring a typical home can start around $400-$1,000 and might run $1,500-$3,000 or more for an extensive upgrade (lots of outlets, light fixtures) in a larger home. A Boston homeowner[1] is spending $2,600 on a do-it-yourself project rewiring a 2,300-square-foot home, including hiring an electrician to install the new electrical panel.
  • Depending on local rates, having an electrician rewire your home can run about $65-$120 per device (outlet, switch, light fixture), plus $800-$3,000 to upgrade to a 100-200 amp electrical panel. Average total cost (materials and labor) for rewiring a house starts around $3,500-$8,000 for a moderate-sized home with easy access (at least 18-inches of crawlspace under the home plus an accessible attic) but can run $8,500-$20,000 or even as high as $30,000 for a large house and/or one with difficult access.

What should be included:
  • If your house is on a concrete slab or doesn't have an attic (or both), it will probably be necessary to cut open the walls about 2 feet up from the floor, as well as cutting through the ceiling joists. Many electricians recommend having the rewiring done while you're on vacation, and say a project will often cost more if you continue living in the home while the work is done. Having an electrician rewire a house generally takes 3-10 days, or about a week for the average older home. However, a complex project can take even longer. offers an introduction[2] to home wiring, including useful terms and safety tips.
  • Rewiring a home is painstaking and time-consuming work. explains how to fish wires[3] through the walls of your home and at[4] a do-it-yourself shares the progress of a rewiring project.
  • Rewiring a home requires a building permit and inspections of the work at certain stages in project; check with your local planning department for specifics. All wiring must meet the National Electrical Code[5] , but local building regulations can also affect the scope and cost of your rewiring project.
Additional costs:
  • If holes must be cut in the walls to run wiring, be sure the cost of the plaster or drywall repair is included in the estimate -- these repairs can be as much as 25-30 percent of the total cost of the rewiring project.
  • You might want to rent a self-storage unit for anywhere from $40-$230 a month to house your valuable furniture and decorations during the rewiring process, which can be quite dusty and invasive.
  • Whether you do it yourself or hire a pro, books on home wiring[6] run about $10-$20 and can provide a good overview of what's involved in a rewiring project.
Shopping for rewiring a house:
  • Request and contact references, check for complaints with the Better Business Bureau[7] and make sure the electrical contractor is properly bonded and insured, as well as licensed in your state[8] .
  • Referrals to electrical contractors are available from the National Electrical Contractors Association[9] .

Electrician: Mr. Electric of Greater Seattle
I had my knob and tube wiring removed from a 672 SF home, brought to current day standards (romex). Installed three smoke detectors which run off of the electric instead of battery operated. Installed ventilation fans in kitchen and bath. There was some drywall to be patched afterward which cost $450 and was done with a different contractor.

House fire damaged small part of house but insurance contract allowed for "rewiring residential structure with copper wire and conduit and gave the entire square footage of the house. rnDoes this mean new wiring throughout or will some of the existing wiring be used Also is conduit a common practice

Electrician: My Hubby
We lost our homeowner's ins due to alum wiring & now can't find another co. to insure us. Through the BBB, I got several quotes from electricians that ranged from $9K to $18K with lengthy time frames that varied wildly. My husband decided to rewire the house himself. To date, we have almost tapped out the $5K 0% credit card we got for this purchase & he's still got a long way to go. We do, however, have all the supplies & tools already purchased--he's just having to swap out the odd thing, buy something he finds he needs, or buy another tool he needs. I don't foresee a lot more money but it's going to take a V-E-R-Y long time to finish and we're almost 5 weeks in. But by doing it himself, he gets to keep all the tools he purchased, there has been no drywall damage so far, & he's learned a LOT. I'll just be glad when it's done and we're insured again!!

Electrician: School District
I work for a very small school district and we just got an estimate for $8,000, 2 men, 80 hrs, to rewire a wall for 6 microwaves in our cafeteria and to up the amps on one wall for a Xerox copier. No wonder the schools have no money!! UNBELIEVABLE -- that seesm totally exorbitant. Am I correct in that thinking?

I had my 1300sf house (built in the 70's with aluminum wiring) rewired along with my kitchen remodel. This included a new panel. New recessed lighting throughout. Garage and smoke detectors were done on a previous remodel. I also repiped at the same time for about 5000. Total cost of remodel was 32k.

Electrician: All Hours Electric
For peace of mind and to avoid being dumped by our insurance company, we had all the knob and tube wiring replaced in our 1919 craftsman home shortly after moving in. The electrician installed a larger panel, added outlets, lights, switches, added new grounding rods and ran romex throughout our 2850 sq ft house. He did the job solo and it took almost a month to complete. He was very good about minimizing the damage he inflicted on our walls & ceilings, so the patch work was minimal.
