What we do inside old walls

Six services for pre-war your city houses, each with what it costs and what it deliberately leaves alone.

What we do

Work that disappears into the walls

Nearly everything here is invisible when it is finished, which is exactly why we photograph it. You should be able to see what you paid for after the plaster goes back.

01

Whole-home rewire

Three to five weeks in an occupied house, sequenced so you never lose power overnight. We fish through plaster where the run allows and cut neat access where it does not, then photograph every concealed run and patch to paint-ready.

  • Power on every night
  • Fished through plaster where possible
  • Every run photographed
  • Patched to paint-ready

$14,500

typical 1.5-storey

02

Panel & service upgrade

Almost every heritage rewire ends at the panel. We replace the fuse box, upgrade the service where the load calculation calls for it, and coordinate the your local utility disconnect around your rewire schedule rather than as a separate project.

  • Load calculation, not guesswork
  • utility disconnect coordinated
  • Grounding and bonding brought current
  • Circuits mapped and labelled

with rewire

03

Grounded circuits & devices

An adapter does not make a two-prong outlet grounded, and a three-prong receptacle on an ungrounded circuit is worse than the two-prong it replaced. We run proper grounded circuits, or fit GFCI protection and label it honestly where a rewire is not yet possible.

  • Real grounds, not adapters
  • GFCI protection where rewiring must wait
  • Every device labelled honestly
  • Kitchen and bath circuits to current code

from

$165

per circuit

04

Heritage fixture rewiring

Your 1920s pendants can usually be rewired with modern cloth-covered cable and made safe without losing what makes them worth keeping. We tell you plainly when a fixture is beyond saving and should be reproduced instead.

  • Modern cable inside original fittings
  • Sockets and insulation replaced
  • Honest verdict on unsalvageable pieces
  • Reinstalled and load-tested

from

$145

per fixture

05

Basement & attic remediation

Old your city basements accumulate junction boxes, open splices and circuits that go nowhere. We trace and map everything, remove what is dead, box what must stay, and hand you a drawing of what is actually there.

  • Every circuit traced and mapped
  • Open splices boxed or removed
  • Abandoned runs pulled out
  • As-built drawing provided

from

$3,200

06

Insurance & pre-purchase reports

Insurers and buyers ask specific questions about knob-and-tube, fuse panels and aluminum. We inspect, photograph and answer those questions in the format they expect — including when the honest answer is that the house is fine.

  • Photographed evidence throughout
  • Written for underwriters, not for us
  • Turnaround inside three business days
  • Second copy to your agent on request

from

$390

per report

In every rewire we quote

  • A written scope naming the wiring era and material of every run
  • Permits pulled and the your local utility inspection booked
  • Photographs of every concealed run before it is covered
  • Plaster fished rather than demolished wherever the run allows
  • Patching taped, sanded and primed to paint-ready
  • An as-built drawing of the finished circuits

What we leave to others

  • Painting and decorating
  • Plaster restoration beyond patching
  • Asbestos abatement in old insulation
  • Furnace and mechanical work

Paint, plaster restoration and asbestos abatement each belong to a licensed trade of their own. We coordinate and take nothing for it.

Worth doing while the walls are open

These are only inexpensive while access already exists. We list them at survey time so you decide once, not twice.

Whole-home surge protection

Type 2 device at the panel.

Additional circuit

+$165

Smoke & CO interconnect

Hardwired and linked.

+$180 per device

Exterior receptacle

GFCI, in-use cover, sealed penetration.

+$310

As-built drawing set

Reviews

From owners of old houses

4.9 from 190 reviews · 340 houses rewired since 2006

“1908 house, knob-and-tube in three rooms and a fuse panel. Four and a half weeks, power every night, and the photographs of every run are now in the file I will hand the next owner.”
EEleanor SadowskiArmstrong's Point
“They talked me out of rewiring the second floor — showed me photographs proving it had been done properly in the 1980s. That honesty cost them about five thousand dollars of work.”
JJonah MbekiHistoric District
“Our insurer wanted knob-and-tube gone before renewal. Heritage Wire did the work and wrote the letter in the exact form the underwriter wanted. No follow-up questions at all.”
