Whole-Home Rewiring in Manchester, NH
Knob-and-tube, cloth-insulated cable, and overloaded two-wire circuits replaced with grounded modern copper — planned to keep your household running while we work.
Is Your Home's Wiring Older Than You Are?
A rewire is the most consequential electrical project a homeowner can take on, and it's one we plan room by room before a single cable gets pulled. We map every existing circuit, design the new layout around how you actually live — dedicated kitchen appliance circuits, AFCI protection in living areas, grounded outlets everywhere — and stage the work so you keep lights and refrigeration each night. Old knob-and-tube and cloth-jacketed cable come out or get permanently decommissioned, never just abandoned hot in the walls.
The need is real in this city. Rimmon Heights multifamilies and other pre-1970 Manchester homes commonly run on 60- or 100-amp services with two-wire ungrounded branch circuits that were never meant to feed modern kitchens, mini-splits, and home offices. Insurers have noticed too: several carriers now decline or surcharge policies on homes with knob-and-tube, which makes a documented rewire an investment that pays back at renewal time and at resale.
Our crews fish new cable through existing bays wherever possible, keeping wall openings small, square, and easy for a plasterer to patch. Every circuit is tested, labeled, and signed off by the Manchester inspector before we call the job done, and you receive a complete circuit directory and permit record for your files.
What a Full Rewire Does for an Older Home
The 5.0-star rewiring process Manchester homeowners recommend to their neighbors — safety, capacity, and paperwork all handled.
Fire Risk Removed at the Source
Brittle insulation, ungrounded splices, and overfused circuits are the classic ignition points in old homes. A rewire eliminates them wholesale.
Insurance-Ready Documentation
Permit records, inspection sign-offs, and a licensed electrician's completion letter — exactly what carriers ask for on older properties.
Capacity for Modern Loads
Dedicated 20-amp kitchen circuits, laundry circuits, and room-by-room AFCI protection sized for how households run in 2026.
Phased to Fit Your Life
We can rewire floor by floor or system by system, so occupied homes and tenanted multifamilies stay livable throughout.
New Homeruns, Cleanly Landed
Every new circuit gets its own properly torqued termination and clearly labeled breaker position. A rewire is only as good as its panel work, so we treat the landing of each homerun with the same care as the cable runs themselves.
Verified Circuit by Circuit
Before closeout we test insulation resistance, polarity, and grounding on every single run, then load-test the distribution as a whole. You get a written test record — not just our word — that the new system performs.
Old Wiring We Replace Across Manchester
Every era of Manchester construction left its own wiring behind. We've replaced all of it.
Knob-and-Tube Replacement
Full removal of live K&T from attics, walls, and basements — the wiring most NH insurers now flag at renewal.
Cloth-Insulated Wire Removal
Mid-century cloth and rubber-jacketed cable turns brittle with age; we swap it for modern NM-B and MC cable.
Ungrounded Circuit Conversion
Two-wire circuits rebuilt with proper equipment grounds so every outlet in the house is genuinely three-prong safe.
Phased & Partial Rewires
Kitchen-only, floor-by-floor, or renovation-driven rewiring scoped to your budget and your contractor's schedule.
Multifamily Rewiring
Unit-by-unit rewires for duplexes and triplexes with separate metering kept clean and tenants kept powered.
Dedicated Circuit Additions
New homeruns for mini-splits, ranges, dryers, and workshops added during the rewire while access is easy.
Inside a Whole-Home Rewiring Project
Every engagement includes the following as standard.
Rewiring Done Right in New Hampshire's Oldest Housing Stock
With 10+ years rewiring southern NH homes, we've learned where every era of builder hid the hard parts.
Plaster-Friendly Methods
Long fish bills beat big demolition. We route through basements, attics, and closets before we ever cut a wall.
Balloon-Frame Fluency
Many pre-war Manchester homes are balloon-framed, which changes how cable drops run — and we plan for it from day one.
Tenant-Aware Scheduling
For multifamily owners we coordinate notice, access windows, and outage timing so units stay rented and tenants stay happy.
Permits Pulled, Every Time
A rewire without a permit record is a resale problem waiting to happen. Ours close out with city inspection sign-off.
Utility Coordination Handled
When the rewire touches the service, we schedule the Eversource disconnect and reconnect so you're not the one on hold.
Dust Control That Matters
Plastic containment, floor protection, and a nightly vacuum-out — because you're living in the house while we work.
Whole-Home Rewiring FAQ
A typical single-family rewire runs one to two weeks; a two- or three-unit multifamily takes longer since we stage around tenants. Plaster walls, finished basements, and blown-in insulation add time because fishing cable gets slower. We give you a day-by-day schedule with the quote so you know which rooms are affected when.
Almost never. We sequence the work so you have functioning lights, refrigeration, and at least one bathroom circuit every night. Short planned shutdowns happen during cutover days, and we schedule those with you in advance — usually mid-morning to mid-afternoon while the house is empty anyway.
They're separate scopes, though they often make sense together — an old 60-amp fuse box can't properly serve a new set of circuits. If your service needs upsizing we'll price it alongside the rewire; you can read more on our dedicated electrical panel upgrades page. Bundling the two saves on labor since the walls are already open.
Frequently, yes. Many NH carriers surcharge or refuse homes with active knob-and-tube, and eliminating it can restore standard rates or reopen coverage options. We provide the permit close-out and a signed completion letter, which is the documentation most underwriters want to see before adjusting the policy.
