Owners of older houses in Claremont usually start asking about rewire house cost after something small: a breaker that trips when the microwave and the kettle run together, a fuse box an insurer has asked about, or two-prong outlets in every bedroom. A full rewire is work for a licensed crew, under permit, with inspections before the walls close. The price depends on what is already in the walls and how hard it is to reach.
We price a rewire after we have seen the panel and opened a few cover plates, not before. Tell us the age of the house and send a photo of the panel with its door open, and we will book a visit and write the rewire quote.
What a rewire involves in an older Claremont house
A full rewire replaces the branch circuits that feed every outlet, switch and light. Old runs come out where they can be reached and are cut dead where they cannot. New cable goes in on a circuit plan drawn for the way you use the house now, with dedicated lines for the kitchen, the laundry and anything else that draws heavy current.
In houses built before about 1970, we tend to find one of three things behind the plaster: knob-and-tube on porcelain insulators, cloth-covered cable from the middle of the century, or a mix of both with newer runs spliced in by earlier owners. Each one changes how much has to come out and how carefully.
A rewire fits on its own, and it fits well as the first stage of a whole home remodel. If a kitchen remodel is in your plans, the new kitchen circuits can be roughed in during the rewire so that work is not paid for twice.
What sets the rewire house cost
Five lines in the quote carry most of the number.
The wiring we find. Knob-and-tube is often easier to pull out of open attic and crawl space runs than cable stapled inside finished walls. Mixed systems with buried splices take longer to trace. Aluminum branch wiring, where it turns up, is its own decision. We open boxes at the visit so this line rests on what we saw.
Panel and service size. An old fuse panel or a small breaker panel rarely has room for the circuits a modern house needs. Replacing the panel is one line. If the service coming from the utility is also too small, upgrading it is a larger line, and the utility's own scheduling becomes part of the timeline. We tell you at the visit which case your house is in.
Wall access. A raised floor with a crawl space and an open attic above lets the crew fish new cable from above and below with small openings. A single story on a slab, a second floor with no attic access, or rooms with plaster ceilings all mean more openings. The quote counts them room by room.
Patch and paint. Every opening has to be closed. On drywall that is quick. On original lath and plaster, matching the surface takes more time, and the quote says how far we take it: patched and ready for paint, or patched and painted to the nearest corner. If you want walls refinished as part of the same job, our flooring and drywall crew can take that on.
Permit. A rewire is permitted work with a rough inspection before walls close and a final at the end. A rewire's permits are the local building department's decision. We check that for your street address and settle it before the quote reaches you. The permit and inspection visits are their own line.
Decisions that change the scope
A few choices at the visit move the job one way or the other.
Full or partial. If the panel is sound and the wiring is mostly newer cable, rewiring a few rooms may be enough. If knob-and-tube is still live, we usually price the whole house, since the openings needed to reach it cover most of the rooms anyway. You see both prices when both make sense.
What you plan to add. A car charger, central air, an electric range or a heat pump water heater can push the house to a bigger panel or service. Planning for them now costs less than adding capacity later.
Rooms that stay finished. If a room was recently plastered or painted and you want it touched as little as possible, we can route around it, often through closets, attic and floor. That choice can change the labor line, and we show the difference.
Grounding and protection. New circuits are installed with grounding and the protection current code calls for. Where old outlets stay on a partial job, we explain what changes at each one.
How the visit and written quote work
At the visit we open the panel, check the service, look in the attic and the crawl space, and pull a sample of cover plates in different rooms to see what wiring is behind them. We note the wall finish in each room and where openings will go.
The written quote then lists the wiring removed, the circuit plan, the panel and any service work, the openings by room, the patch and paint finish, and the permit. Optional items sit below the base scope. If a wall holds something we could not see from the box, we stop, show you, and price it in writing before going further.
What to have ready
- The age of the house and any past electrical permits you have.
- A photo of the panel with the door open, and of the meter.
- A list of appliances or equipment you expect to add.
- Access to the attic hatch, the crawl space and every room.
- Which rooms you need powered while work goes on, so we can phase the circuits.
We take rewire work across Claremont and in La Verne, San Dimas and Glendora close by. Call us or send the form with a photo of the panel, and we will set a time to see the house.
