Whole Home
Rewiring.

Worcester is full of beautiful old homes — Colonials, Victorians, three-deckers — and a lot of them still have knob-and-tube, cloth-insulated, or aluminum wiring. If your insurance company is asking, your inspector flagged it, or you're just tired of flickering lights and warm outlets, we rewire it the right way. Phased. Permitted. Liveable while we work.

Identify Your Wiring

Three Reasons
Your Home Needs Rewiring.

If your home has any of these three wiring types, it's not just outdated — it's a fire risk and an insurance liability. Here's how to spot them.

Pre-1950 Homes

Knob & Tube

Two separate cloth-wrapped wires running through ceramic tubes and supported by porcelain knobs. No ground wire, no insulation jacket. Common in Worcester homes built before 1950.

Risk
High
1965–1973 Homes

Aluminum Wiring

Silver-colored conductors (instead of copper). Used during the 1965–1973 copper shortage. Aluminum expands, contracts, and oxidizes — connections loosen over time and overheat.

Risk
High
Pre-1965 Homes

Two-Prong Outlets

No ground hole. Often paired with cloth or rubber-insulated wiring that's brittle and crumbling. Modern appliances (computers, microwaves, TVs) need a ground for safety and surge protection.

Risk
Moderate

Insurance Companies Are Watching

Most major insurers in Massachusetts now refuse to write or renew policies on homes with active knob-and-tube or aluminum wiring. If you got a non-renewal letter or your premium just spiked, this is almost always why. A documented rewire (with permits and inspection sign-off) restores coverage — and often saves more on premiums than the work costs over a few years.

What's Included

Every Rewire
Includes This.

Rewiring is a big job. We make sure every quote is itemized and the scope is exactly right for your home.

Standard Inclusions

Everything You Get

  • Pre-Rewire Walkthrough & Plan We map every existing circuit, identify wiring types, and document what gets replaced before any work starts.
  • All-New 12 / 14 AWG Romex Modern copper NM-B cable with proper ground conductor. 14 AWG for 15A circuits, 12 AWG for 20A circuits and kitchens / baths.
  • All Outlets, Switches & Boxes Three-prong grounded outlets throughout. Tamper-resistant in living spaces. New switches and standard-depth boxes.
  • GFCI / AFCI Where Code Requires GFCI for kitchens, baths, garages, basements, and exterior. AFCI for bedrooms, living rooms, and most habitable spaces.
  • Old Wire Disconnected & Abandoned Safely Old knob-and-tube and aluminum is de-energized and properly terminated. We remove what's accessible and leave the rest dead behind walls (per code).
  • Permits Pulled & Inspections Coordinated Rewires require multiple inspection stages — rough-in (walls open) and final. We pull permits and schedule each inspection.
  • Insurance Documentation Letter A formal letter signed by us — confirming the rewire was completed, permitted, and inspected — for your insurance company. Often restores your policy or unlocks discounts.
  • 1-Year Workmanship Warranty All wire, terminations, and devices we installed covered for 12 months from final inspection.
Scope Options

Not Always All-or-Nothing.

Some homes need a full whole-home rewire. Others just need partial replacement of specific runs. We size the scope to your situation.

Targeted Replacement Smallest

Replace specific old runs (knob-and-tube in attic, aluminum in kitchen) while leaving newer modern wiring intact.

Whole Home Rewire Most Common

Replace 100% of original wiring throughout the house. Restores insurability. Most older homes need this.

Rewire + Panel Upgrade Best Value

Pair the rewire with a 200A panel upgrade. Same permits, same inspections, future-proofed for EV charger and modern loads.

Most rewires are paired with a panel upgrade. If your old wiring is going, your old panel is probably going too. Learn about panel upgrades.

Phased Approach

How a Rewire
Actually Works.

We don't tear up the whole house at once. Most rewires happen over 1–3 weeks, phased so you can keep living in the home.

01

Survey & Detailed Quote

1–2 Hours On-Site

We come out, identify the wiring types, count outlets and switches, map circuits, and locate the panel. You get a written, itemized estimate showing what's getting replaced, the order of phases, and a realistic timeline. No deposits required to get a quote.

02

Permits & Schedule

1–2 Weeks Lead Time

We pull permits with your town and schedule the start date around your calendar. You don't deal with town hall. If utility coordination is needed (panel upgrade paired with the rewire), we handle that with National Grid or Eversource.

03

Run New Wire — Room by Room

5–10 Working Days

We work one section at a time — usually starting in the attic and basement (easy access), then progressing through bedrooms, common rooms, and kitchen / bath last. New copper Romex runs through joists and walls. Old wire is de-energized as we go. Most rooms only lose power for a few hours during their swap.

04

Devices & Final Connections

2–3 Days

New three-prong outlets, switches, GFCI / AFCI protection, and any new fixtures get installed. Every device gets tested and labeled. Old panel circuits are mapped to the new wire.

05

Rough-In & Final Inspection

2 Inspections, ~3 Hrs Each

The town electrical inspector signs off in two stages — rough-in (while walls are open) and final (after everything's covered up and reconnected). Both inspections are required and we coordinate them with the town.

06

Documentation & Handoff

Same Day As Final

You get the final inspection sticker, a signed letter for your insurance company documenting the rewire is complete, and a labeled circuit map for the new panel. Workmanship warranted for 12 months.

You Don't Have to Move Out

The #1 fear about rewiring is "where will we sleep?" Don't worry — most rewires are done while you live in the home. Power is only off in the room being actively worked on, usually for a few hours at a time. We schedule work around your routine — the room with the home office, the kid's bedroom, the kitchen — all timed to minimize disruption. Drywall stays mostly intact; we fish wire and use small access cuts that finish flush.

Common Questions

Rewiring FAQs.

  • Almost never. The vast majority of rewires are done while the homeowner stays in the house. Power is only off in the room being actively worked on — usually for a few hours at a time — so you can keep using the kitchen, bathrooms, and bedrooms in the rest of the home. We schedule around your routine so you're not in a dead zone for the whole day. The exceptions are very large multi-floor jobs or homes where the panel and main service are coming out at the same time — even then, full lockouts are usually one or two days, not weeks.
  • For an average single-family home, plan on 1 to 3 weeks of active work, plus a week or two of permit lead time before we start. Smaller homes or homes with accessible attics and basements move faster. Larger homes (3,500+ sq ft), three-deckers, and finished historic homes with plaster walls take longer because access is harder. We give you a realistic timeline at the estimate — not the optimistic version.
  • No. We use the attic and basement to run wire wherever possible — usually 70–80% of the work happens in those spaces with zero impact on living areas. Where we do need access through walls, we make small, targeted cuts (typically 4×4 inches near outlet boxes) that are easy for any drywall finisher or handyman to patch flush. We don't do drywall finishing or paint touch-up — but we leave clean cuts and we'll tell you upfront at the estimate roughly how many patches you should plan for. Plaster homes need a bit more care; we discuss that case-by-case.
  • Three things, all of which we hand over the day the work is finished: (1) the permit and final inspection sticker from your town's electrical inspector, (2) a signed letter on company letterhead stating the home has been rewired, the wiring types replaced, and the date of completion, and (3) a labeled circuit map showing the new panel layout. This package is what insurance companies want to see — they can then write or renew your policy. Many homeowners see their premiums drop or their non-renewal letter rescinded within weeks.
  • Almost always yes. If the wiring is old, the panel usually is too. Doing both together saves you money — one set of permits, one round of inspections, one utility coordination — and you finish with an entirely modern electrical system that's ready for whatever you add next (EV charger, mini splits, kitchen reno). Learn more about panel upgrades. We quote both as a combined scope when it makes sense.
  • Per Massachusetts code, no — abandoned wiring just has to be de-energized and properly terminated. We remove what's accessible (visible runs in the attic and basement) and leave dead wire safely terminated behind walls if pulling it would require ripping open finished surfaces. This is standard practice and inspectors expect it. Once the wire is disconnected from the panel, it can't carry current — so it's not a fire risk anymore.
  • Sometimes — depends on what's there. If the worst of the old wiring is concentrated in one area (e.g., knob-and-tube only in the upstairs bedrooms while downstairs has 1990s Romex), targeted replacement is a reasonable approach. But if the whole house has aluminum or knob-and-tube, partial work usually doesn't satisfy your insurance company, doesn't save much money, and means we'll be back tearing things up again later. Doing it all once is usually the better long-term decision, but we'll be honest with you about your specific situation at the estimate.
  • Cost depends on square footage, number of circuits, wall type (drywall vs. plaster), access (open attic vs. finished), and scope (targeted replacement vs. full rewire vs. rewire + panel upgrade). Smaller targeted replacements are at the low end. A full rewire of an average-sized older home is a significant investment — but it's the kind of investment that restores insurability, eliminates fire risk, and modernizes the home for the next 50+ years. The only honest way to give you a real number is to see the home. Estimates are free, itemized, and never pressure-driven.
