How Much Does It Cost to Rewire a House? (2026)
As of 2026, a house rewire costs $4,000 to $20,000. That is about $4 to $10 per square foot, based on published cost guides. In California the price is often lower, closer to $2 to $6 per square foot. Two things drive the price most: the size of your home, and whether the walls are open for a remodel or closed up because you still live there. Rufino Electric checks your wiring first and gives you a clear, written price before any work starts.
What does it cost to rewire a house in 2026?
A full rewire runs $4,000 to $20,000 for most homes. That is roughly $4 to $10 per square foot, based on 2025 and 2026 cost guides. A California-only guide puts it closer to $2 to $6 per square foot, or $4,000 to $8,000. That lower range fits many smaller and mid-size High Desert homes. These numbers are market ranges, not a quote. Rufino Electric inspects your wiring and gives you an exact price in writing before we touch anything.
What moves the price up or down
A few real factors change the range above.
The size of the home. More square footage means more circuits and more wire runs. A small home or one addition costs far less than a full house.
Access. In a home you still live in, we work through attics, crawl spaces, and small openings. That protects your drywall, but it takes more time. In an open remodel, the walls are already open. The same wiring goes in faster and usually costs less.
The age and shape of the old wiring. A full rewire replaces everything. A targeted repair costs less but only fixes one bad circuit.
New circuits and outlets. Adding devices, extra outlets, or a dedicated circuit for a shop, an EV charger, or solar and a battery adds to the job.
The permit. A rewire needs a permit and a final inspection from the city or San Bernardino County. We pull it and handle the paperwork.
Do you need a full rewire or just targeted repairs?
Maybe not a full rewire. Old or damaged wiring can be unsafe. But not every home needs a top-to-bottom job. Rufino Electric checks your wiring first. We give you an honest answer: a full rewire, or just a targeted fix, like one bad run or an electrical repair in one spot. Either way, you get a free estimate and one clear scope.
Signs your High Desert home may need a rewire
- Breakers trip often, even with normal use.
- You still have two-prong outlets with no ground wire.
- Lights dim or flicker when other appliances turn on.
- You smell something hot or see scorch marks near outlets or the panel.
- You are remodeling, adding an ADU, or already opening walls.
- Your home was built before 1970 and has never been rewired.
Victorville has 571 homes built in 1939 or earlier. That is the largest count of old homes in the Victor Valley, and many still run on original cloth-covered wiring. About half the homes in Apple Valley, and close to half in Hesperia, date to the 1970s and 1980s. That wiring and those panels are past their design life. If that sounds like your home, a panel upgrade alone may not be enough. It is worth having the wiring itself checked too.
What the rewiring process looks like
Most Victor Valley homes are detached, single-family houses on their own service. That keeps the job simple: one panel, one meter, no shared-building problems. We inspect your wiring first and walk you through what needs to change. Then we pull the permit before any work starts. In a finished home, we route new wire through attics and crawl spaces to limit drywall damage. In an open remodel, we run it directly. We test every circuit, the inspector signs off, and we back the job with a 1-year warranty on labor and a 2-year warranty on parts and equipment.
Is a house rewire worth it?
Often, yes. A rewire clears out fire hazards from old or damaged wiring. It stops breakers from tripping for no reason. It gives you the power for modern loads like EV charging and solar. It also looks clean to an inspector or a buyer later. But a rewire is a real cost, so get the honest read first. Sometimes a targeted repair fixes the real problem for less.
Frequently asked questions
How do you know if a house needs to be rewired? Watch for frequent breaker trips, two-prong outlets with no ground, flickering lights, warm outlet covers, or a home built before 1970 that has never been rewired. Rufino Electric checks the panel and wiring and gives you an honest answer, not a guess.
How long does it take to rewire a house? It depends on the size of the home and how easy the walls are to reach. A single room or a partial rewire can take a day or two. A full rewire in a home you still live in usually takes several days to more than a week, since crews work through finished walls, attics, and crawl spaces instead of tearing them open.
Can you rewire a house without removing drywall? Often, yes. We can fish new wire through attics, crawl spaces, and existing openings in many homes. That limits drywall repair. Some interior walls with no attic or crawl space access may still need a small opening, which we patch after.
