How Much Does It Cost to Rewire a House? A Complete Breakdown

Rewiring a house is one of those projects most homeowners hope they never need, but aging wiring, frequent breaker trips, or a major renovation can make it unavoidable. The total cost depends heavily on the size of your home, the accessibility of the wiring, and where you live. Here's a practical breakdown of what goes into the price and how to budget for it. ## Typical Cost Ranges by Home Size Electrical contractors usually price rewiring jobs based on square footage, though the final number can swing widely. As a general guide: - Small homes or condos (under 1,000 sq ft): typically the lowest total cost, since fewer circuits and outlets are involved - Medium homes (1,000–2,000 sq ft): the most common range for whole-house rewires - Larger homes (2,000+ sq ft): higher costs due to more circuits, longer wire runs, and often multiple panels or subpanels Older homes with plaster walls, finished basements, or outdated panels generally fall at the higher end of any range because the work takes longer and requires more patching. ## What Drives the Price Up or Down Several factors influence your final bill more than raw square footage does. Understanding them helps you see where your money goes: - Accessibility: Wiring in an unfinished basement or crawlspace is far easier to replace than wiring buried inside plaster or finished walls. - Panel upgrades: Many rewires include replacing an old panel with a higher-amperage service, which adds a meaningful chunk to the total. - Outlet and switch count: Every device you add or relocate means more labor and materials. - Local labor rates: Electrician rates vary considerably by region. - Permits and inspections: Most jurisdictions require a permit for a full rewire, and inspection fees are usually baked into the quote. - Material choices: Standard copper wiring is the norm, but specialty fixtures, smart-home wiring, or additional circuits (like for EV charging) increase costs. ## The Hidden Costs Homeowners Forget ### Wall Repair and Repainting A whole-house rewire involves opening walls and ceilings, and most quotes cover the electrical work only. Drywall patching, texture matching, and repainting can add a noticeable amount to your budget if you hire out the work, or a lot of your own time if you DIY. Ask your electrician whether cleanup and minor patching are included before you sign anything. Other commonly overlooked items include temporary power arrangements (you may need to be without electricity for stretches), updating outdated fixtures or outlets to meet current code, and possible asbestos testing in very old homes before walls are disturbed. ## Partial vs. Full Rewiring Not every house needs everything replaced at once. If only one room or circuit is problematic, a partial rewire costs far less and can be done in a day or two. A full rewire, by contrast, is a multi-day to multi-week project that touches nearly every room. A licensed electrician can inspect your system and tell you whether you truly need a complete overhaul or whether targeted upgrades, a panel replacement, and a few new circuits will solve the safety issues at a fraction of the cost. Signs that point toward a full rewire include knob-and-tube or aluminum wiring, a fuse box instead of a breaker panel, flickering lights, burning smells, or consistently tripping breakers. ## How to Get the Best Value Rewiring is not a DIY project, but you can still control costs with smart planning: 1. Get at least three itemized quotes so you can compare labor, materials, and permits line by line. 2. Combine the rewire with other work — if you're already renovating a kitchen or opening walls for plumbing, doing the electrical at the same time saves significant labor. 3. Ask about bundling the panel upgrade with any utility rebates or incentive programs available in your area. 4. Plan outlet and switch locations carefully before work begins; changes mid-project are expensive. 5. Verify that your electrician is licensed and insured, and that the quote includes permit and inspection costs. In the end, rewiring is an investment in safety and in your home's value. A clear, itemized quote and a bit of coordination with other projects can keep the cost manageable — and give you peace of mind for decades. ## Related reading - [How to Test an Electrical Outlet with a Multimeter the Safe, Simple Way](/blog/how-to-test-an-electrical-outlet-with-a-multimeter-step-by-step-guide) - [GFCI vs. AFCI Outlets: A Plain-English Guide to Choosing the Right Protection](/blog/gfci-vs-afci-outlets-whats-the-difference-and-which-do-you-need) - [Tripped Breaker?
