How to Rewire Your Home Without Hiring an Electrician (Step-by-Step Guide)


Rewiring a home can seem like an intimidating task, but with proper planning and safety precautions, it's possible for a homeowner to do it themselves without hiring an electrician. As someone who has rewired parts of my home, I've learned that taking it slow and steady is crucial.

In this guide, I'll walk through the step-by-step process I followed to rewire rooms in my home safely and legally. I'll cover planning and preparation, wiring materials and tools needed, safety protocols, shutting off power, removing old wiring, installing new circuits, connecting wires, grounding, covering work, and testing.

While some electrical work does require a professional electrician, there are many rewiring tasks a knowledgeable homeowner can take on. This guide will give you the key steps so you can gain essential electrical skills and save on electrician fees.

Planning and Preparation

Before beginning any electrical work, the first critical steps are proper planning and preparation. Rushing into a rewiring project blindly can be unsafe and lead to costly errors.

Evaluating Electrical Needs


Circuit Mapping

Shutting Off Power

Budgeting and Costs

Materials and Tools Needed

Before getting started, ensure you have the right materials and tools on hand. This will make the rewiring process much smoother.

Electrical Wiring

Conduit and Boxes

Breakers and Panels


Basic tools needed include:

Also have appropriate safety gear like eye protection, work gloves, ear protection for drilling, and insulated tools.

Shutting Off Power

Before touching any wiring, power to the home's electrical system must be completely shut off at the main breaker. Failing to do this properly can result in severe electrocution.

To shut off power:

Removing Old Wiring

With power shut off, you can start removing any outdated, unsafe, or insufficient wiring in the rooms being rewired.

To properly remove old wiring:

The goal is to gut the room down to the bare studs, with power safely disconnected. Now new wiring can be installed.

Installing New Circuits

With the room gutted, it's time to install the new wiring system. Focus on one circuit at a time.

Laying Out Wires

Conduit and Boxes

Connecting Wires


Proper grounding of new wiring is vital for safety. Here are key grounding steps:

Never electrify circuits without properly grounding them first. This protects against electrocution and shock.

Covering Work

Once new wires are installed, the final stage is covering up your work.

Testing and Turn-On

With everything buttoned up, it's time to test and turn the power back on. Work methodically box-to-box to confirm safety and functionality.


While rewiring a home is complex, it can be tackled successfully by an informed homeowner using proper materials, safe procedures, and methodical installation and testing of new circuits.

The keys I've learned are turning power fully off, running wires into code-approved boxes and conduit, making failsafe connections, ensuring robust grounding, and thoroughly testing operation before energizing circuits.

Taking this gradual, safety-first approach allows you to gain substantial DIY electrical skills and the satisfaction of providing your home with up-to-date, safe, and robust wiring.
