Whole-House Rewiring in South Jersey, Done Without Trashing the Plaster
You have an older South Jersey home with wiring you can no longer trust, and you want it replaced start to finish. A whole-house rewire pulls every original branch circuit, the knob-and-tube or early cloth-insulated runs, and replaces it with copper THHN/THWN-2 sized to each circuit and terminated to current NEC and New Jersey code. We do this in finished homes for a living, which means fishing new wire through plaster-on-lath walls and finished ceilings with the smallest access holes we can get away with, not gutting your house. A NJ-licensed Master Electrician (License #17216) is on the job, we pull the township permit before any wire moves, and the local municipal inspector signs off at the end.
DK Electrical Solutions is a family-owned firm serving Burlington, Camden, and Mercer Counties since 2011, and historic-home rewiring is one of the jobs we're built for. We quote a flat rate up front that already includes the permit and inspection, so you know the number before we open a single wall. Anyone quoting a whole-house rewire by the hour is quoting you their uncertainty.
Whole-House Rewire Cost and the Signs You Actually Need One
A whole-house rewire replaces every branch circuit in the home, and the price is a range driven by four things, not a single sticker: the square footage and circuit count, how much of the wall and ceiling is finished plaster, whether a recalled panel and service have to come out with it, and the access your attic, basement, and chases give us. It is a bigger job than a panel upgrade and it is quoted after an on-site walk, never over the phone.
South Jersey reality: Pre-1950 stock in Mount Holly, Moorestown, and Haddonfield is largely plaster-on-lath, which is exactly the construction that punishes a careless rewire and rewards planning the fish-tape route first.
The signs you're looking at a rewire rather than a repair are consistent. You see knob-and-tube or cloth-insulated wire in the attic or basement. Your outlets are two-prong and ungrounded throughout. Breakers trip under normal modern load, or the panel is a recalled Federal Pacific or Zinsco. Any one of those is a conversation. Together, they're a rewire.
The honest test is whether the original system can be brought to code circuit by circuit or whether it has to be replaced wholesale. We tell you which on the on-site estimate, and if a couple of dedicated circuits solve your actual problem, we'll say that instead of selling you a full rewire you don't need.

Knob-and-Tube Wiring Replacement in Finished Homes
Knob-and-tube replacement is the core of most whole-house rewires we do, and it's the work that separates electricians who understand old South Jersey homes from those who don't. Knob-and-tube has no ground conductor, its insulation embrittles after decades, and many insurers won't write or renew a policy on a home that still has it. The fix is to pull it out completely and run new copper, never to splice modern wire onto the old runs.
We run copper THHN/THWN-2 branch wiring sized to each circuit and terminated to code. We never reuse the old knob-and-tube conductor, and we don't leave live legacy wire buried in a wall.
Doing it in a finished home is a fishing problem, not a demolition problem. In a Moorestown or Mount Holly plaster-on-lath house, we plan the route first: what we can reach from the attic, what we can reach from the basement, and which closet and interior chases let us drop or pull a run without opening a finished wall. We work with fish tape, inspection cameras, and vans stocked like mobile supply houses, and we pre-mark and minimize every access hole so the patching afterward is small and clean.
Here's how a knob-and-tube rewire actually sequences:
- Map every original circuit. We trace what each knob-and-tube run feeds, so nothing gets orphaned when the old system comes out.
- Plan the fish-tape access. Attic, basement, and chase runs first; finished-wall openings only where there's no other path.
- Pull new copper and remove the old. Fresh THHN/THWN-2 to each device, and the abandoned knob-and-tube pulled rather than left live in the wall.
- Rough-in inspection. The AHJ inspects the open work before anything is closed up.
- Trim, restore, and final inspection. Devices set, panel labeled, access holes patched, and the municipal inspector's final sign-off.
More of this history sits in Mount Holly than almost anywhere in our footprint. See our knob-and-tube rewires on Mill Street and the Bispham-Hollinshead district for the town-specific picture.
Pairing the Rewire With a Federal Pacific or Zinsco Panel Replacement
In most older South Jersey homes, the wiring and the panel came from the same era, which means the recalled panel and the knob-and-tube are almost always the same conversation. Federal Pacific Stab-Lok and Zinsco/Sylvania panels have documented failure rates, breakers that can fail to trip when they should, and insurers that won't cover a home carrying one. If we're already opening the system for a rewire, replacing that panel at the same time is both safer and cheaper than doing it as a separate job later.
Utility, by town: Southampton, Medford, Marlton, Moorestown, Mount Laurel, Willingboro, and Mount Holly are JCP&L territory. Haddonfield, Cherry Hill, and Trenton are PSE&G, filed through PSE&G Construction Services. We match the disconnect to your town so the job doesn't stall.
When we pair them, every new branch circuit lands on a fresh Square D QO, Siemens, or Eaton CH breaker on copper bus. We don't mix brands inside a panel, and we don't add aluminum branch wiring. The service upgrade and the rewire share one permit, one utility coordination, and one final inspection, so you're not paying twice for mobilization or living through the disruption twice. For the panel side of the work in detail, see pairing a panel upgrade with a full rewire.
Call (609) 796-4177 and a Master Electrician will tell you whether your panel and wiring are one job or two.
When a Full Rewire Is the Wrong Call
We'd rather lose the bigger job than sell you a rewire you don't need, so here's the honest line. If your home was built after roughly 1970, has grounded three-prong outlets throughout, a modern breaker panel that isn't Federal Pacific or Zinsco, and your only complaint is one or two overloaded circuits, you almost certainly do not need a whole-house rewire.
Skip the rewire when: the wiring is already grounded copper or modern NM cable, the panel is current, and the problem is isolated to a room or a single appliance. A couple of dedicated circuits or a targeted repair fixes that for a fraction of the cost.
The same goes for a home where an inspector flagged one aluminum-fed circuit or a single ungrounded run. That's a repair, not a rewire. We'll scope the smallest correct fix, and if that's a dedicated 20A line for the kitchen instead of tearing into forty circuits, that's what we'll quote. A full rewire earns its cost in a genuinely old, ungrounded, or recalled-panel home. It's a waste of money anywhere else.
How We Keep the Plaster Intact
The single biggest fear homeowners have about a rewire is the demolition, and in a plaster-on-lath house that fear is reasonable. Plaster doesn't patch like drywall. So the whole job is planned around access, and the wire is the easy part.
We start in the attic and the basement, because a two-story South Jersey home usually lets us drop runs down interior walls from above and pull others up from below without ever cutting the finished face. Closet backs, chases behind cabinetry, and existing fixture and device boxes become our entry points. Where we do have to open a wall, the hole is pre-marked, cut small and square, and located where a patch will disappear. We photograph the route before we close it so the panel directory and any future work match reality.
Our cleanup is something customers compliment us on every single day. We leave the work area cleaner than we found it, which on a rewire means you're not living in a construction zone for weeks.
None of this makes a rewire a one-day job, and we won't pretend it is. But careful fish-tape work in a finished home is the difference between a rewire you barely notice and one you're still repairing plaster from at Thanksgiving.
Frequently Asked Questions
How long does a whole-house rewire take?
A full rewire is a multi-day project, not a one-day job, and the timeline is set as much by the inspection schedule as by the wire. We pull the NJ permit, complete the rough-in, hold for the AHJ rough-in inspection, then finish trim-out and the final inspection. On an older South Jersey home with knob-and-tube and plaster-on-lath walls, careful fish-tape access through finished ceilings adds time but keeps the demolition minimal. A small home can run several days; a larger or heavily finished home runs longer. Anyone promising a whole-house rewire in a single day is skipping either the permit or the careful finished-wall work.
Can you rewire a house without removing the plaster walls?
We rewire finished plaster-on-lath homes without gutting them, but no honest electrician will tell you a rewire opens zero walls. We plan the route first and pull most runs through the attic, the basement, and interior chases, using existing fixture and device boxes as entry points so the finished face of the wall is left alone wherever possible. Where a wall has to be opened, the hole is pre-marked, cut small, and placed where a patch disappears. The goal is the least invasive path, not a demolition, which is exactly why fish-tape skill in older Moorestown and Mount Holly homes matters.
Do I need a permit to rewire my house in NJ?
Yes. A whole-house rewire in New Jersey requires an electrical permit from your township, a rough-in inspection while the work is open, and a final inspection when it's done. We pull the permit before any wire moves, schedule both inspections, and the local municipal inspector signs off after the work passes. Your flat-rate quote already includes the permit and the inspections. A rewire done without a permit is a resale and insurance problem waiting to happen, so we never skip it.
What kind of wire do you use for a whole-house rewire?
We run copper THHN/THWN-2 branch wiring, sized to each circuit and pulled to current NEC and New Jersey code. AFCI protection is added on the circuits NEC 210.12 requires, such as bedrooms, living rooms, and other habitable spaces, and GFCI protection goes where NEC 210.8 requires it, such as kitchens, baths, laundry, and any outlet near water. We never reuse the old knob-and-tube, cloth, or aluminum conductor, and every junction box ends up labeled and accessible for the final inspection.
Should I replace my panel at the same time as the rewire?
Usually yes, especially if it's a Federal Pacific or Zinsco panel. In most older South Jersey homes the wiring and the panel are the same age, so if the branch circuits are being replaced, the recalled panel is almost always coming out too. Pairing them means one permit, one utility coordination, and one inspection instead of two, which is both safer and cheaper than splitting the work. We land every new circuit on a Square D QO, Siemens, or Eaton CH breaker on copper bus, and we don't mix brands inside a panel.
Will a rewire affect my JCP&L or PSE&G service?
It can, if the rewire is paired with a service upgrade. A branch-circuit rewire alone typically doesn't touch the utility side. But when we replace the panel and service at the same time, we coordinate the disconnect and reconnect with the utility that serves your town: JCP&L for Southampton, Medford, Marlton, Moorestown, Mount Laurel, Willingboro, and Mount Holly, or PSE&G for Haddonfield, Cherry Hill, and Trenton. We schedule that window for you and time the work so power is off for the shortest stretch possible.
