Rewiring a home can be an intimidating task, but with proper planning and precautions it can be done safely without hiring an electrician. The key is taking the time to educate yourself on electrical systems and codes, creating a detailed plan, and working slowly and carefully. With the right knowledge and tools, I was able to rewire my home room-by-room over several months, saving thousands in electrician fees while ending up with much safer and more reliable wiring.

Dangers and Warnings

Before considering a DIY rewiring project, it's essential to understand the dangers involved. Electrical work can be hazardous and potentially life-threatening if proper precautions are not taken. Here are some key risks to be aware of:

Unless you have professional electrical training, rewiring an entire home is not recommended. Consider more limited projects like installing a new light fixture or outlet. And always get the necessary permits and inspections.

How to Prepare for a Rewiring Project

If you do decide to take on a DIY rewire, here are some key steps to prepare:

Safely Rewiring One Room at a Time

The safest approach to a DIY rewire is to work one room at a time, following these key steps:

1. Turn off power to the room

Locate the breaker(s) powering the room and switch them to the "off" position. Then, turn on a light or outlet to confirm power is off before working.

2. Remove old wiring

Take notes on wiring locations as you remove old wires from outlets, switches and junction boxes so you can replicate later.

3. Install new boxes and runs

Anchor new boxes and run new cabling as planned. Staple cables every 18-24 inches for security and stability.

4. Splice wires properly

Use wire nuts or crimp connectors to securely join wires. Wrap connections with electrical tape for additional protection.

5. Confirm proper polarity

Use a multimeter or non-contact voltage tester to confirm hot, neutral and ground wires are properly connected.

6. Add protective plates

Install new electrical outlet and switch wall plates when complete. Never leave exposed wires.

7. Restore power and test

Turn power back on at the breaker and test all outlets, lights and switches. Fix any issues before moving on.

Take your time with each room, sticking to your plan and ensuring all wiring is secured, connected and insulated properly according to code. Get inspections completed prior to concealing any wiring.

When to Call an Electrician

While a DIY rewire is possible for some homeowners, it's critical to know when to call a professional electrician. Here are some situations where expertise is required:

A professional electrician has the skills, knowledge and tools to quickly and safely perform complex electrical work. Their expertise can prove invaluable for major upgrades, troubleshooting issues, and ensuring a safe, code-compliant rewire.


Rewiring a home without an electrician is possible for some DIYers, but comes with substantial risks. To attempt it, you must thoroughly educate yourself on electrical systems, create a detailed plan, and work carefully one room at a time. Focus only on areas you're comfortable with, and don't hesitate to hire a professional when needed. With adequate preparation and caution, it may be possible to safely rewire certain rooms in your home. But there is no shame in calling an electrician - it's better to be safe than sorry when dealing with the dangers of electricity.
