How to Rewire Your Home Without Electrician Help

I've decided to take on the ambitious project of rewiring my home without hiring a professional electrician. As a diligent homeowner, I want to ensure I do this properly and safely. Here is my guide to rewiring a house on my own, covering all the key steps and considerations.

Assessing the Existing Electrical System

Before beginning any rewiring project, it's crucial that I fully understand the current state of the electrical system in my home. This involves:

This assessment will reveal if a complete rewiring is necessary or if I can get by with only upgrading certain circuits. I may also discover wiring issues that need to be addressed for safety.

Making a Rewiring Plan

Once I understand the current electrical system setup, I can start planning out the rewiring project. Key steps here include:

Careful planning at this stage will allow the rewiring project to go smoothly and efficiently once I start.

Safely Shutting Off Power

Before touching any live wires, I need to shut off power to the areas I'll be working on. For safety:

Working with live electrical wires can be extremely hazardous. I will always verify power is shut off in the area I'm rewiring before starting any hands-on work.

Removing Old Wiring

With power shut off in the work area, I can start removing existing wiring. For this:

Slow and steady is the name of the game. No wires get disconnected until I'm 100% sure power is off. My circuit mapping will also help ensure I get the right wires out.

Running New Wiring

Now the fun part - running all new wires throughout the home. Key steps for this process include:

The process is slow going, but rewarding as I see the new wiring come together section by section. I take care not to damage insulation and keep wires neatly bundled.

Installing New Outlets, Switches and Fixtures

Nearing the finish line now! After new wires are run, I can start installing:

I'll take care to make tight, secure wire connections by twisting ends together with pliers before capping with a wire nut. This helps prevent wires from loosening over time.

Turning Power Back On and Testing

Here comes the moment of truth! When all wiring is complete, I'm ready to turn power back on:

By using diligent testing procedures, I can locate and fix any minor issues with the new electrical system before officially completing this major DIY rewiring project.


While certainly challenging, rewiring a home without professional help is entirely feasible if done carefully. By fully assessing the existing system, creating a smart wiring plan, running new wires correctly, and thoroughly testing all work, I can upgrade my home's electrical service to modern standards - all without hiring an electrician. Paying close attention to safety is also crucial when dealing with lethal voltages. With proper precautions however, a diligent DIYer can definitely take on rewiring their residence for an immense sense of satisfaction.
