Rewiring a House Cost

How Much Does Rewiring a House Cost?

low costLow: DIY Materials Can Run $1,500-$3,000average costAverage Range: $3,500-$8,000+high costHigh: Large House w/Difficult Access Can Run $30,000+
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, and make sure the electrical contractor is properly bonded and insured, as well as licensed in your state.
  • Referrals to electrical contractors are available from the National Electrical Contractors Association[7] .

I have had three electricians look at my 2500 sq ft house. Knob and tube, ungrounded. Tenants upstairs have lost electricity twice. One electrician said 43000, the 2nd said don't do it, ungrounded knob and tube is perfectly safe. the third wants 80,000 minus a discount. He says smaller estimates are out of date and for the Midwest. I am in California. Help. I don't know what to think.(#2 and 3 are Diamond Certified) and contradictory.)Price listed is for last estimate.

Electrician: pending
My home has knot and tub wiring, except for updated areas in the bathroom and in an in-law unit. The house is old and has some nice wood wainscoting, which would cause problems with two outlets. Built, 1912, 2500 sq. ft. One electrician gave an estimate of 43,000, then wouldn't put it in writing. A second ridiculed the whole idea of rewiring, said there was no danger, a third gave a detailed estimate of 81,000 minus a 10% discount. I think that so much apartment building in the vicinity makes electricians reluctant to do relatively small residential jobs. I don't know what to do.

Everyone is crying about the cost to do electrical work. The liability of doing electrical rewire is tremendous. Not to mention the cost of license, tools and insurance. The is also the training involved to become a master electrician.
I challenge you to do your own rewire one time. Most people would gladly pay the rates after experiencing what us pros do.

Rewiring a House in Dallas, Texas
Amount: $18,000.00 total

Electrician: Ready Electric
Your advice is a little deceptive.
Simply saying to rewire a house has a huge range of options that can drive up the cost especially since pricing for markets are locally determined by demand. Dallas demand has gone up alot due to much investment in residential housing. You should say that to rewire an older ungrounded house requires new wire with a ground,run to ALL ELECTRICAL receptacles, switches, ceiling light boxes and virtually anything that uses electricity. I'm skeptical that the DIY has the knowledge or expertise to do this as cheaply as you say. Missteps can easily lead to a fire hazard. Your LICENSED electrician should be insured supplying a current Insurance Certificate. One house I'm working on has two feet of blown cellulose insulation on top of everything in the attic. This is the only access and will take alot of time to dig through to find the old wires and where they lead. DIY may can rewire one switch but a whole house is beyond their reach.

partial house rewire
Amount: $5,000.00 total
Posted by: jukeboxjohnnie in Anaheim, CA.Posted: May 19th, 2015 05:05AM
Electrician: electrician
We live in Southern California in a 1500 square foot historical home--built in 1947. The electrician charged $2700 to upgrade the panel from a 100 amp to a 200 amp. We had to apply for and pay for the city permit ourselves. After completing that, he gave us a separate estimate for $2,252 JUST to rewire 23 plug outlets, (no switches or lights), stating it would take him about 4 days. This estimate was made based on his hourly rate rather than by the job. Although he had easy access under the house (at least 2 feet of clearance), he only rewired 12 of the outlets, and still charged us the full $2,252 price, which wound up costing us about $190 per outlet. He also kept all the materials (romex and outlet boxes) we paid for, even though he only used half of them. Beware of a contractor who bids your project based on hourly charges, rather than by the job. Experienced guys already know about how long it will take them to complete it, and they charge in proportion to that. This guy was extremely slow because he doesn't normally re-wire homes. Another contractor told us our home layout was not complicated at all, and the contractor should have been able to complete all 23 outlets with no problem for the same amount of money we paid him. Make sure you hire an electrician who has plenty of experience doing complete re-wiring jobs, and not just making his living doing small lighting stuff. We will not be using this guy again.

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: 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.
