Rewiring replaces worn or overloaded wiring and fixes the circuit plan behind it. Our electrical rewiring services cover one branch after a renovation as well as a whole house, and an electrician finds out what the walls hold before agreeing how much to change.

Common problems

How do I know if my house needs rewiring?

Many callers have just bought an old house and find outlets that are dead, loose or have no ground. Others have a renovation that opens a wall and shows what is behind it.

ESFI lists flickering lights, warm or discolored plates, buzzing or sizzling outlets and a burning odor as warning signs. Rewiring becomes the answer when the cause sits in the wiring itself:

  • A renovation exposes fragile wiring or crumbling insulation
  • Joints turn up outside accessible boxes
  • Several new rooms share one old circuit
  • Outlets are two-prong, ungrounded or very old
  • Part of the house has no power and the breaker is not the cause

Is it a repair, a partial rewire or a whole-house rewire?

That is the question the inspection answers. A single bad branch may need only that branch replaced. If the wiring behind every wall is the same age and condition, a whole-house rewire may be the honest answer.

We explain which one applies before you decide.

Field notes

What did we find on real rewiring jobs?

Job 01

A bedroom extension in a renovated ground-floor unit exposed fragile wiring, and the old insulation crumbled at the box. The carrying route inside was long, so planning mattered. We replaced the affected branch, and the new wiring passed testing.

Job 02

A kitchen renovation uncovered hidden joints. The splices sat outside accessible boxes. We rerouted and enclosed the connections, so the next electrician can still inspect them.

Job 03

An attic conversion overloaded an old feed, because several new rooms shared one branch. We built a revised circuit layout, and each load got a proper supply.

Technician quote

Rewiring should correct the circuit plan as well as the cable condition. We identify hidden joints and added loads before agreeing how much wiring needs replacement. Our work addressed a bedroom extension exposed fragile wiring: we replaced the affected branch.

Quotes

Is a rewiring quote free, or do I pay for a diagnostic visit?

Many callers want a price up front and do not want to pay several companies to look. For rewiring the answer is straightforward: a rewiring project is a defined, high-end job, so the quote is free. A fault that has not been traced yet is a different case.

JobHow you get a priceWhat to expect
Whole-house or partial rewiringFree quoteThe call center gives an estimate when you book, and the electrician confirms it after inspecting the wiring.
New circuits for an ADU, garage, shed or added roomFree quoteHave the distance from the panel, the panel brand and the house age ready, and photos of the area if you have them.
Outlet dead, no ground, or part of the house without powerDiagnostic visit firstThe electrician traces the fault before pricing the repair. A diagnostic visit can carry a charge, which varies and is usually under $50.

Phone estimates cannot cover everything in an old house, so the electrician looks before the final price.

Process

How does a rewiring job work from the first call?

01

Call, and the call center answers right away. Or send the form, and we aim to call you back within five minutes.

02

You receive a time slot and a price estimate.

03

You book, and the timeline adjusts if you are renovating on a schedule.

04

A licensed electrician visits, checks the wiring, boxes and joints, and inspects the project.

05

If you accept, work can begin that visit, or you can book it for a later date.

Tell the call center about any rooms you plan to add or open up. Same-day appointments are often available, depending on electrician availability.

Safety and permits

Can I rewire or add an outlet myself, and do I need a permit?

Whether the circuit can carry another outlet

Whether the box and the old wiring are in good condition

Whether the outlet has a working ground

A new outlet connects to a live circuit through hot, neutral and ground wires. A wrong connection can cause shocks or fires, so we do not give home wiring steps. A licensed electrician checks the circuit, the box and the ground first.

Permit and inspection rules depend on your city or county, and the electrician tells you what your job needs. Rewiring is work for a licensed electrician. ESFI advises that heavy extension cord use is a sign you may need more outlets: Don’t Overload Your Home
