Home Rewiring in Jersey City, NJ
Older homes with knob-and-tube or aluminum wiring are a serious fire and safety risk. Malfettone Electric rewires properties top to bottom — safely, cleanly, and with minimal disruption. We've been protecting Hudson County homes since 1977.
Is Old Wiring a Risk?
Eliminate the Hazard. Protect Your Home.
Knob-and-tube wiring — common in Jersey City homes built before 1950 — was never designed for modern electrical loads. It has no ground wire, deteriorates over time, and is a leading cause of residential fires. Insurance companies increasingly refuse to cover homes with knob-and-tube wiring.
Aluminum wiring (common in homes built between 1965–1973) expands and contracts with heat, loosening connections over time and creating fire risk at outlets and junction boxes. Both situations require professional remediation — and we've handled both in hundreds of Hudson County homes.

Warning Signs
Does Your Home Need Rewiring?
Old wiring doesn't always announce itself. These are the signs we see most often in Hudson County homes — and any one of them warrants an inspection.
Flickering or Dimming Lights
Lights that flicker when appliances run — especially on the same circuit — point to overloaded or deteriorating wiring.
Frequently Tripping Breakers
A breaker trips occasionally by design. If yours trips regularly, the circuit can't handle the load — a common sign in pre-1970 homes.
Burning Smell from Outlets
Any burning odor near outlets, panels, or switches is a serious fire warning. Old insulation on knob-and-tube wiring burns and doesn't always spark visibly.
Two-Prong Ungrounded Outlets
Two-prong outlets mean no ground wire — which means no protection for electronics or people. A sure sign of pre-1960s wiring that needs replacement.
Home Built Before 1960
Knob-and-tube wiring was standard from the 1880s through the 1940s. If your home is pre-1960, there's a high chance it still has some in the walls.
Insurance Is Refusing Coverage
Many NJ insurers now require knob-and-tube removal as a condition of coverage. If your policy was non-renewed, rewiring resolves it.

What NJ Homeowners Say
“Our 1920s rowhouse had original knob-and-tube throughout. Malfettone rewired the whole house in four days — two-prong outlets gone, new panel, everything up to code. Our insurance company actually sent a thank-you letter.”
“We noticed a burning smell from our walls and called Malfettone immediately. They were at the house within a few hours, found deteriorated knob-and-tube insulation in the attic, and got us scheduled for a full rewire that week. Honest, fast, and no pressure.”
“Bought a 1940s home and knew the wiring was original. Malfettone gave us a detailed written quote, rewired everything during our renovation, and coordinated the permit and final inspection. Everything passed on the first try.”
Common Questions
Home Rewiring FAQs
How do I know if my home needs rewiring?
Signs your home may need rewiring include: flickering or dimming lights, frequently tripping breakers, burning smells near outlets, two-prong (ungrounded) outlets, visible knob-and-tube or aluminum wiring, or if your home was built before 1960. A licensed electrician can inspect and give you a definitive answer.
How long does a full home rewiring take?
A full rewire of a single-family home typically takes 3–7 days depending on size and accessibility. We work systematically through each room, minimizing holes in walls and disruption to your household. Most families remain in the home during the project.
How much does home rewiring cost in NJ?
Home rewiring in NJ typically ranges from $8,000–$20,000 for a full single-family home, depending on square footage, the number of circuits, accessibility, and whether a panel upgrade is included. Malfettone Electric provides a detailed written quote before any work begins.
Is knob-and-tube wiring dangerous?
Yes. Knob-and-tube wiring was standard from the 1880s through the 1940s, but it's now a serious fire and safety hazard. It lacks a ground wire, can't handle modern electrical loads, and degrades dangerously over time. Many NJ homeowners insurance policies now require its removal.
Do I need permits for home rewiring in NJ?
Yes. Home rewiring in New Jersey requires an electrical permit and a final inspection by a municipal electrical inspector. Malfettone Electric handles all permit applications, coordinates inspections, and provides documentation of all work performed — so your home's electrical record is clean and current.
How much does knob-and-tube wiring replacement cost in NJ?
Replacing knob-and-tube wiring in a New Jersey home typically costs $8,000–$18,000 depending on the size of the home, how much of the wiring is knob-and-tube, and ceiling/wall accessibility. Partial replacement (specific circuits or a single floor) can run $2,500–$6,000. All work is permitted, inspected, and documented so you have a clean electrical record for insurance and future sales.
Will my homeowners insurance cover knob-and-tube wiring replacement?
No — homeowners insurance does not pay for rewiring. However, many NJ insurers will refuse to renew or issue a new policy on a home with active knob-and-tube wiring, or will charge significantly higher premiums. Completing the replacement eliminates the insurance roadblock and typically reduces your premium. We can provide documentation of completed work that satisfies most insurer requirements.
