Why it matters

Old wiring methods that were fine in 1955 are dangerous in 2026 — most insurers now refuse to cover homes with active knob-and-tube. A rewire makes your home safe, insurable and ready for modern loads.

How it works

  1. 1. In-home assessment to map existing wiring and plan the safest path.
  2. 2. Written scope, timeline and price — plus permit pull.
  3. 3. Careful, low-impact rewire with detailed cleanup and inspection.

Rewiring an older home without destroying it

The Susquehanna Valley is full of beautiful older homes — and a lot of them still have original knob-and-tube, cloth-insulated branch wiring, or two-prong ungrounded outlets. We rewire them the careful way: fishing through walls from attics, basements and closets to keep finished plaster, hardwood and trim intact wherever we can.

When wall openings are unavoidable, we plan them small, neat and easy to patch. You'll know up front what's coming, where, and why.

Insurance, inspections and resale

Many PA insurers now refuse to renew policies on homes with active knob-and-tube, federal pacific panels or aluminum branch wiring. We can write a scope to satisfy your insurer or home inspector, prioritize the highest-risk circuits first, and stage the work over time if a full rewire isn't in the cards immediately.

Common questions

Do I have to move out during a rewire?

Usually no. We stage the work room-by-room, keep power on to the rest of the house, and tarp/clean each area at the end of every day.

Can you just replace the dangerous parts?

Often yes — we can prioritize the highest-risk circuits (kitchens, baths, knob-and-tube serving outlets) and stage the rest over time if a full rewire isn't in budget right now.

The Clear Electric approach

More than a quote — a plan you can actually follow.

Most homeowners and business owners we meet have been burned before — a vague verbal price, a crew that disappears mid-job, or a "finished" install that fails inspection. Our old construction rewiring & knob-and-tube replacement process is built to be the opposite of that: everything in writing, every step explained, and a single electrician you can call from the first phone conversation through the final walkthrough.

Because we're a local Susquehanna Valley company, we're not routing you through a call center or subbing your job out to whoever is cheapest that week. The person who quotes your old construction rewiring & knob-and-tube replacement project is on site, accountable for the work, and lives in the same community. If something needs a follow-up in six months, we pick up the phone.

We take old construction rewiring & knob-and-tube replacement work seriously because electrical is one of the few trades where doing it "mostly right" isn't good enough. Loose neutrals, undersized conductors, missing bonding, or an ungrounded circuit can sit hidden in a wall for years — until it starts a fire or fries a $3,000 appliance. Every job we finish is one we'd be comfortable handing off to any inspector in the state.

Signs it's time to call

Don't wait for the sparks.

If any of these sound familiar, it's worth a conversation before it becomes an emergency:

  • Breakers that trip repeatedly — even on lighter loads
  • Outlets or switch plates that feel warm to the touch
  • Flickering or dimming lights when large appliances kick on
  • A burning or plastic smell near a panel, outlet or fixture
  • Older two-prong outlets or knob-and-tube wiring still in service
  • Extension cords running as permanent wiring
  • A panel that hasn't been touched since the house was built

Materials & standards

Quality parts. Nothing swapped behind your back.

We stock and install trusted, contractor-grade brands — the same gear your local inspector expects to see in the panel. If a product is on backorder or we're recommending an upgrade, we tell you before it goes in.

Square D, Siemens, Eaton
Generators
Generac (dealer-authorized)
Wire & conduit
Southwire, copper-first
Devices

Safety & code

Built to current NEC — and the way we'd wire our own house.

Every old construction rewiring & knob-and-tube replacement job follows the current National Electrical Code plus any Pennsylvania and local amendments. That means correct grounding and bonding, arc-fault and ground-fault protection where required, properly sized conductors, torqued lugs, and clean, labeled panelwork you can actually work on later.

  • AFCI/GFCI protection where code requires
  • Properly torqued lugs and terminations
  • Labeled circuits & updated panel schedule
  • Correct grounding & bonding path
  • Permits and inspection when required
  • Copper conductors sized to real load

"They quoted what they charged. Nothing extra tacked on at the end. The panel looks better than the day it was installed."

Homeowner, Lewisburg

"Called Tuesday, generator running by Friday. Cleanest install I've seen — and I've had two others quoted."

Homeowner, Milton

"Our shop needed rewiring in phases so we could stay open. They worked around us and every deadline hit."
