How Much Does it Cost to Rewire a House?

When you're looking to rewire your whole house, you can typically expect to pay $5,000-15,000 to rewire a 1,500 to 3,000-square-foot home, including labor and materials.

The cost to rewire a house will vary according to:

  1. whether you'll need a replacement electrical panel (for example, to replace a fuse box or to upgrade your panel's capacity to the contemporary standard minimum 200 amps)
  2. how much the necessary building permit and inspection process cost in your area
  3. how many electrical devices your home includes
  4. whether you need new grounding rods
  5. how accessible your electrical system is

Cost Breakdown

Cost to rewire a house will normally include:

  • Materials and Supplies -- Materials comprise flexible sheathed cable (today's new non-metallic wire which is replacing copper wire), outlets, switches, and supplies.
  • Labor -- Rewiring your home is a very labor-intensive process, which can take up to one full workweek. It should be done by an experienced and conscientious licensed electrician. Your electrician may need to cut holes in your walls to accommodate the new wiring; check whether your contract will include the cost of repair.

Get the Most for Your Money

Never risk fire or electrocution by trying to do electrical work yourself. (Note that homeowners insurance often does not cover damage due to DIY repairs.) Hire a professional, licensed electrician to rewire your house or perform other electrical installations or repairs -- especially if you have old fabric-insulated or aluminum wiring.

Ask your electrician to install important safety equipment like smoke detectors and carbon monoxide alarms while he is at your home.

Thinking of buying a property that is more than 25 years old? Check the condition of its wiring and determine the cost of necessary upgrades before you make an offer.

In a large-scale home remodel, have the wiring upgrade done early on, before any plastering work begins.

If you are currently living in the home, consider moving to temporary accommodation while the rewiring is going on -- it can be extremely messy and disruptive.
