Whole-Home Rewiring

For homes where the wiring itself — not just the panel — has fallen behind what the house actually needs.

Rewiring comes up for a few distinct reasons, and they call for different approaches. Some homes still have knob-and-tube wiring or aluminum branch wiring from the 1960s and 70s, both of which carry known safety concerns and are frequently flagged by insurers and home inspectors. Others have copper wiring that's simply undersized or ungrounded for today's electrical loads. And some homeowners are rewiring specific rooms as part of a larger renovation, not the whole house.

A full rewire — running new wiring throughout the home and reconnecting every device, switch, and fixture — is the most thorough option and is usually done alongside other renovation work, since it's far less disruptive when walls are already open. Where that's not practical, a partial or room-by-room rewire addresses the highest-risk circuits first (kitchens, bathrooms, and any area with visibly damaged or outdated wiring) while leaving lower-priority areas for a later phase.

We assess the existing wiring type, condition, and grounding before recommending an approach, and we're direct about what actually needs replacing versus what's still safe. Not every older wire needs to come out — the goal is addressing genuine risk and code gaps, not maximizing the scope of the job.

What's included
  • Inspection of existing wiring type, age, and condition
  • Identification and replacement of knob-and-tube or aluminum branch wiring
  • New grounded circuits where the home currently lacks proper grounding
  • AFCI/GFCI protection added per current code
  • Phased or room-by-room rewiring options for occupied homes
  • Coordination with drywall/renovation contractors when rewiring is part of a larger project

How it works

From first call to finished work.

01

Inspect

We open up access points to assess wiring type, condition, and grounding throughout the home.

02

Scope the work

You get a clear plan: full rewire, phased rewire, or targeted replacement of the highest-risk circuits.

03

Rewire

New wiring is run, terminated, and tested circuit by circuit, minimizing disruption to occupied rooms where possible.

04

Finish & inspect

Devices, fixtures, and panel connections are completed and the work is inspected before walls are closed up.

Frequently asked

Whole-Home Rewiring questions, answered.

How do I know if my home has knob-and-tube or aluminum wiring?+

Knob-and-tube wiring uses ceramic knobs and tubes visible in unfinished areas like attics and basements, and was common before the 1950s. Aluminum branch wiring was common in the late 1960s and early 1970s and requires a trained eye to identify safely. We can inspect accessible wiring and tell you what you actually have.

Do I have to rewire my entire house at once?+

No. Many homeowners rewire in phases, starting with the highest-risk circuits or the areas involved in a current renovation, and addressing the rest over time.

Will rewiring affect my homeowner's insurance?+

It can help. Some insurers charge more or decline coverage for homes with known knob-and-tube or aluminum wiring, so replacing it can improve your insurability and sometimes your premium.
