Home Rewiring & Old Wiring

Home Rewiring and Old Wiring Replacement

Rewiring your home depends on the age of your wiring, your current circuit needs, and how much access we have to your walls. We help you decide whether to replace selected circuits or your entire system.

Older wiring is not all the same. We look at the conductor type, the insulation, the grounding, and how the circuits currently load your panel to tell you if you need a repair or a full update.

We perform a visual check of your accessible wiring, the panel, your devices, the attic, the basement, and the crawlspace. Since we cannot see through walls until we start, we will tell you what we assume and how we handle finish repairs. We always explain what might change the plan as we work.

Selected circuits, phased work, or a larger rewire

We can rewire your home in phases to keep your rooms usable. If you are already planning a remodel, we can coordinate our work with your open walls to improve access.

Knob-and-Tube ReplacementWhen we find this older wiring, we look at where it goes, if it touches insulation, and how it connects to your modern devices. We replace what is necessary based on its actual condition.
Aluminum Wiring RemediationHomes from the mid 1960s to mid 1970s often have aluminum branch wiring. We look at the connections and use COPALUM crimps or AlumiConn connectors to repair each connection, or we replace the runs. We tell you which repair actually fits.
Ungrounded OutletsTwo-prong outlets often mean your circuits lack a ground. We look at your wiring and tell you the best path for your home, whether that is a new circuit or a different safety update.
Whole-Home RewiresWe can coordinate a whole-home project with your remodel. If you need to keep living in your home, we phase our work so you always have power where you need it.
Rewiring During a RemodelWhen you have open walls, we can easily run new wires. We work with you to plan your outlets, your switches, and your lighting before we close the walls back up.
Permits and InspectionWe manage the permit process for you. In Idaho, we work through the DOPL. In Washington, we work through L&I. We make sure every step meets the current NEC 2023.

Signs your home needs new wiring

These signs usually mean you should have us look at your system. We will check the device, the breaker, and the wiring to find the real cause.

Two-prong, ungrounded outletsIf your home has two-prong outlets, we test your circuits. We help you choose the safest way to bring your power up to date.
Flickering lights or warm outletsFlicker and heat can mean a loose connection or a failing device. Turn off the breaker for that area and call us to check the wiring before you use it again.
Cloth-insulated wiring found in a remodelIf you open a wall and see old cloth insulation, call us. We look at the conductor condition and splices to tell you if it needs to be replaced.
Knob-and-tube or aluminum branch wiringFinding these types of wiring is common in the Palouse. We check the condition and the load to tell you how we can fix it.
Breakers that trip often in an older homeIf your breaker trips repeatedly, we look at the load on that circuit. We tell you if you need a new circuit or just a simple repair.

The cost depends on how many circuits we replace, how easy it is to reach your attic or crawlspace, and how much wall we have to open. We give you an exact price in writing after we walk your home, with the access and patching assumptions spelled out.

Questions customers usually ask

Do I need to rewire my whole house at once?

No. We often fix specific circuits or phase the work. We look at your grounding and loads to see what needs to be prioritized.

Will you have to open up the walls?

Sometimes. We use attics and crawlspaces when we can. If we need to open a wall, we tell you exactly where and why.

How long does a rewire take?

It depends on how many circuits we move and how we phase the work. We give you a timeline once we look at your specific home.

Does a rewire need a permit?

Yes. We handle the permit for your project. We follow the NEC 2023 for every connection we make.
