Knob-and-tube, cloth-covered cable, aluminum branch circuits, and ungrounded outlets belong to another era. We pull the old wiring, run modern grounded copper through the whole house, and hand you the documented, code-compliant system that insurers and buyers want to see.
Most homeowners stay in the house while we work. We keep the mess and disruption down.
A whole-home rewire replaces the wiring running through your walls, floors, and ceilings with modern, grounded copper cable, from the panel out to every outlet, switch, and fixture. It's the fix for the aging systems that older Bergen County homes are full of: knob-and-tube from before the 1940s, brittle cloth-covered cable from the mid-century, and aluminum branch wiring from the late 60s and early 70s.
The reasons to do it are safety and grounding first. Old wiring has no ground, its insulation dries out and cracks, and it was never built for the loads a modern home runs. A rewire brings the whole system up to current code, adds proper grounding, and gives you grounded three-prong outlets throughout. It's almost always paired with a panel upgrade, since a new system deserves a modern panel to feed it.
It's a big job, and we treat it like one. We plan it around your home, keep the wall damage as limited as the layout allows, and handle the permit and inspection. When it's done, you have a house that's safer, insurable at standard rates, and ready for anything you want to plug into it.
The decade a home was built tells you a lot about what's behind its walls, and how likely it is to need a rewire. Pick the era that fits your home for a quick read.
Homes this old very often still have some active knob-and-tube wiring, which is ungrounded and increasingly refused by insurers. A full rewire is usually the right call, and the paperwork afterward is what gets you back to standard coverage.
A general guide based on typical construction. The only way to know for sure is to have the wiring looked at, which we're glad to do.
For a lot of homeowners, the push to rewire doesn't come from a spark. It comes from an insurance letter. Carriers increasingly refuse to write or renew policies on homes with active knob-and-tube wiring, and some set a hard deadline to replace it as a condition of coverage.
Here's the part that catches people out: insurers care whether any live knob-and-tube exists, not what percentage you've dealt with. Splicing new wire into a few old circuits usually leaves you in the same category. A documented full rewire is what moves you back into the standard market, and the permit, our certification, and the town's final inspection are exactly the paperwork a new carrier wants to see. Timing it before your renewal lets you re-shop with a clean report.
People picture a rewire as tearing every wall open, and it isn't. Most of the work happens by fishing new cable through existing wall and ceiling cavities, using the same access points electricians have relied on for years. We open small, targeted holes where we have to, not the whole surface, and we plan the routing to keep those to a minimum.
Most homeowners stay in the house through the job, which typically runs one to three weeks depending on size and access. When we're done, there's some patching and painting to handle, and we're upfront about that from the start. Because the walls are open anyway, a rewire is also the ideal moment to add modern protection you'd otherwise pay to retrofit later, like whole-house surge protection at the panel and the GFCI and AFCI protection current code calls for. Old wiring is also a leading cause of the calls that come into our emergency line, so a rewire is as much about preventing those 2am moments as it is about insurance. It's the deepest version of our everyday residential work.
The towns we cover are full of exactly the homes that need this work, and we've rewired plenty of them. From the pre-war homes of Ridgewood and Ho-Ho-Kus to the postwar streets of Allendale and our home base in Waldwick, we know which era brought which wiring, and it makes the whole job faster and cleaner.
Victorians and early colonials where knob-and-tube and cloth cable are common finds.
Older stone and Tudor homes with wiring that predates modern grounding entirely.
Postwar split-levels and ranches where 1960s and 70s aluminum branch wiring turns up.
Colonials and capes minutes from the shop, where we rewire and upgrade together.
A pre-war colonial got a non-renewal notice over active knob-and-tube. We rewired the home in grounded copper, upgraded the panel, and handed over the permit and inspection paperwork, so the family re-shopped their policy at standard rates.
A 1960s split-level had aluminum branch wiring throughout with a growing list of trouble spots. Rather than chase each one, we rewired the affected areas in copper and left a system that's safe and consistent.
An older home was still running two-prong outlets on cloth-covered cable with no ground. We rewired it, added grounded outlets and modern protection, and made it safe for today's electronics.
A rewire is a significant project, and the price has less to do with the wire itself than with your house. We give you one clear number after we walk the home, with no surprises once the work starts.
The biggest factors are the size of the home, the number of stories, and how easy it is to get behind your walls. Plaster walls, finished spaces with no access, and homes without a basement or crawl space all take more work. Whether a panel upgrade comes with it, and how much patching the layout demands, round out the picture. Since the federal credits for this kind of work have ended, we'll be straight that this is an out-of-pocket investment, and a genuinely worthwhile one.
One call gets a real electrician who looks at what you actually have, tells you honestly whether it needs a rewire, and prices the whole job up front, paperwork included.
