Why Rewire Without an Electrician

Rewiring a home is a daunting task, but with proper planning and precautions, it can be done safely without hiring an electrician. I decided to rewire my home myself to save on labor costs. I have some electrical experience from past home projects, but this was my first major rewiring endeavor. With the right materials, tools, and lots of research, I was able to completely rewire my house over a few weekends.

Rewiring yourself allows you to upgrade and customize your home's electrical system. I was able to add more circuits, larger gauge wiring, and grounding to areas that lacked it. While hiring an electrician is sometimes the best option, DIY rewiring is worthwhile for certain homeowners. It just requires courage, patience, and caution.

Dangers and Precautions

Electrical work presents risks of electrocution or fire. Proper safety steps must be taken to avoid hazardous shocks or sparks. Here are some key precautions I took when rewiring:

Rewiring must be done with great care and respect for the dangers. Rushing or ignoring safety will put your life at risk. I treated electricity with extreme caution throughout the process.

Planning the Rewire

Careful planning is crucial before tearing into walls for a rewire. I spent weeks researching, making plans, and gathering supplies before starting work. Key steps in my planning process included:

Thorough planning ensures you buy enough materials, understand what you're getting into, and can work efficiently once the rewiring begins. Rushing into a rewire without proper forethought invites problems down the road.

Running New Wiring

The key steps I followed when running new wiring through my home were:

I ran all new 12/2 NM cables from a central panel location to device and fixture boxes. For high wattage appliances like dryers, I used 10/2 wiring. Careful installation techniques prevent damage and ensure safe connections.

Installing New Devices

After running wires, I installed all new outlets, switches, and junction boxes:

Devices must be well supported and wired properly to work correctly and be safe. Having an electrical box too recessed or loose in a wall cavity can be a hazard. I took care securing boxes and verified devices were operational before completing the wall.

Connecting the Panel and Finishing Touches

The last steps were connecting to the main panel and finishing the rewiring project:

Taking the time to correctly label and test all circuits ensured everything functioned properly when I restored power. I also weather sealed any access holes and cleaned up my work area thoroughly.


Rewiring a home without an electrician is an ambitious project, but entirely doable for some homeowners. Extensive planning and strict safety protocols are essential. Patience and attention to detail helps the job go smoothly. While not for everyone, rewiring your own home brings great rewards when you can upgrade outdated and potentially hazardous electrical systems savings thousands in the process. I was extremely satisfied seeing all the new lighting, outlets, switches and clean wiring I installed bring my home up to modern safety and efficiency standards.
