Whole-home rewiring for Bay Area homes
Older wiring can be a safety risk and a limit on how you use your home. We replace it with modern, grounded, code-compliant wiring built for the way you live now.
What whole-home rewiring is
Whole-home rewiring replaces the wiring that runs through your walls, floors, and ceilings with new cable installed to current code. It is the right answer when a home still has its original wiring from decades ago, when that wiring is damaged or ungrounded, or when the electrical system cannot keep up with how the home is used today.
Remnant Electric plans the new circuit layout, pulls fresh cable to every room, and lands it cleanly at the panel and devices as a family-owned electrical contractor serving the Bay Area, California.
Why old wiring is worth replacing
Wiring installed decades ago was not built for the loads modern homes place on it. Insulation gets brittle, connections loosen, and the lack of a ground wire leaves appliances and people less protected.
New wiring adds a ground path, restores safe capacity, and brings the system up to the code your home has to meet when you sell, insure, or remodel.
Who whole-home rewiring is for
Any homeowner living in an older property, or planning a change that touches the electrical system, should know the signs that wiring is due for replacement.
An older home with original wiring
Homes built decades ago may still carry wiring that is past its safe service life and due for replacement.
Two-prong, ungrounded outlets
Outlets without a ground slot are a sign the wiring behind them has no ground path, which modern devices expect.
Breaker trips and flickering lights
A system that struggles to keep up with everyday loads may be telling you the wiring or circuits need upgrading.
Visible damage or cloth wiring
Cracked insulation, exposed conductors, or cloth-covered cable are clear signs the wiring needs attention.
Adding major new loads
Planning an EV charger, addition, or appliance upgrade is a good time to bring old wiring up to current code.
Selling, insuring, or remodeling
Buyers, insurers, and permit offices often expect grounded, code-compliant wiring before a sale or renovation.
Know your wiring
The kind of wiring in your walls tells you a lot about whether it is time to rewire. Here is a plain-language guide to the types we see most often in older Bay Area homes.
Knob-and-tube wiring
Common before the 1930s
Two conductors run through ceramic knobs and tubes, with no ground wire. The insulation gets brittle with age and it was never sized for modern appliance loads.
Often due for replacement
Aluminum branch wiring
Common in the 1960s and 1970s
Single-strand aluminum conductors can loosen at switches, outlets, and fixtures, generating heat at the connections and raising fire risk where they terminate.
Worth a closer look
Cloth-insulated cable
Common through the mid-1900s
Rubber and cloth insulation breaks down over decades, leaving conductors exposed and prone to shorts, especially where the cable bends or enters a box.
Often due for replacement
Modern grounded cable
Current standard
Today's grounded cable carries a ground wire, durable insulation, and the conductor size needed for modern circuits, appliances, and devices.
What we install
Not sure what kind of wiring your home has? An on-site inspection answers that question and gives you a clear picture of what, if anything, needs replacing.
Benefits of whole-home rewiring
Rewiring is an investment in safety, capacity, and the long-term value of your home.
A safer electrical system
New, intact wiring with a ground path removes the hazards that come with aging insulation and loose connections.
Capacity for modern loads
Right-sized circuits handle today's appliances, devices, and future upgrades without overloaded wires or tripped breakers.
Work done to current code
Rewiring brings your home up to the electrical code required for sales, insurance, and permitted remodels.
A home that is ready for what is next
Grounded outlets, dedicated circuits, and clean routing make additions, EV chargers, and appliance upgrades straightforward.
Rewiring options
From a full property rewire to replacing a single aging circuit, we match the scope to what your home actually needs.
Whole-home rewiring
A full replacement of the branch wiring throughout the property, planned and routed to current code.
Older wiring replacement
Targeted replacement of aging or damaged wiring, such as cloth-insulated or aluminum branch circuits.
New circuit installation
Dedicated circuits for appliances, EV chargers, or additions, added alongside or as part of a rewire.
Remodel and addition rough-in
Wiring roughed in for a remodel or addition, coordinated with the rest of your electrical system.
Every option above is part of our whole-home rewiring service.
What to expect
A whole-home rewire is a bigger project than a repair, so we keep the process clear and communicated from start to finish.
- 1
Inspection and scope
We walk the property, identify the existing wiring, and define the scope of the rewire with an honest, upfront quote.
- 2
Planning and scheduling
We plan the new circuit layout, coordinate the schedule, and talk through access and what to expect each day.
- 3
Rough-in
We pull new cable through walls, floors, and ceilings, route it cleanly, and land it at the panel and device boxes.
- 4
Trim-out and devices
We install outlets, switches, plates, and fixtures, then label the panel so every circuit is easy to find.
- 5
Test and walkthrough
We test every circuit, confirm the work meets code, clean up, and walk you through what was done.
