Introduction
Rewiring your home may seem like a daunting task, but with the right planning and preparation, it can absolutely be done in a single weekend while saving you thousands of dollars. As a first-time homeowner who successfully rewired my entire house in one weekend, I want to share my step-by-step guide on how you can do the same.
Gather Materials and Tools
The first step is gathering all the materials and tools you'll need for the project. Here's what I'd recommend having on hand:
Materials
- Romex wire - Make sure to get enough 12/2 and 14/2 NM electrical wire in various lengths to rewire your entire home. Calculate the square footage and add extra.
- Electrical boxes - Have plenty of electrical boxes in varying sizes for outlets, switches, and junction points.
- Wire nuts - You'll need a large pack of red, tan, and yellow wire nuts to connect the wires.
- Breakers - Gather any new breakers your electrical panel requires. Check amperage limits.
Tools
- Voltage tester - This lets you safely check if wires are live before working on them.Critical for safety!
- Cable ripper - Makes removing stapled electrical cable easy.
- Wire strippers - For stripping Romex wire properly.
- Pliers - For twisting wire nuts tightly.
- Drill/screwdriver - For drilling holes and securing boxes.
- Ladder - For accessing ceilings and high walls. Don't risk injury by climbing on furniture.
- Headlamp - Provides hands-free light when working in dark spaces.
- Electrical tape - For covering junction boxes and breaker labeling.
Shut Off Power and Remove Old Wiring
Safety first! Turn off all the circuit breakers and main power switch to the home. Verify power is off with a voltage tester before touching any wires.
Next, go room by room removing all the old electrical wiring. A cable ripper tool makes this much easier than using just pliers and wire cutters. Remove any wire staples or clips to free the cable from the studs.
Don't be afraid to cut the wires leaving plenty of length coming out of the boxes. New wire will be pulled into each box later. Just focus on removing all the old wires completely.
Coil up the old wires neatly to prep them for recycling or trash day.
Run New Wires and Secure Boxes
Now the fun part begins - running all new electrical wiring throughout the home. Start by running wire between your electrical panel and the first outlets and switches in the circuit. Clamp the Romex securely to the studs every few feet.
Pay attention to leave enough extra wire in the boxes to make connections easily. Having 10-12" of wire in the box is ideal.
Drill holes through studs if necessary to run wires to different rooms and floors. Also secure any new electrical boxes to studs or joists using screws.
Connect the Wires and Install Breakers
Once all the new wire is run and boxes are secured, it's time to make the wiring connections.
Carefully match the wire colors - black to black, white to white, and bare copper ground to green or bare copper. Use wire nuts to connect wires securely, twisting clockwise until tight.
Double check you connected the black (hot), white (neutral), and ground wires properly in each box according to building codes. Getting this wrong can be a fire hazard!
For 240 volt circuits like those for HVAC systems, water heaters, and dryers, make sure the red and black wires are on opposite 120 volt phases.
Finally, install any new breakers needed in your electrical panel and securely connect the wires. Follow the amperage limits for breakers and wire size. Add labels for each new circuit you installed.
Shutting off the main and verifying no live wires before doing panel work is critical to avoid getting shocked. Exercise extreme caution working in the panel.
Test and Turn Power Back On
You're almost done! Flip all the breakers and main power switch back on.
Now grab your voltage tester and verify that power is running to all new circuits and outlets. Test every outlet to make sure wiring is connected properly. If not, flip the breakers off and check for loose wires or bad connections.
If everything checks out, install covers on the outlets, switches, and junction boxes. Screw in light bulbs and verify all fixtures are working properly. Circuit by circuit, turn the new breakers on and test everything.
Congratulations, you just rewired your whole home safely in one weekend and saved thousands of dollars doing it yourself! Now it's time to crack open a cold one and relax knowing your home's electrical system is safer and up to code.
FAQs
How much will I save by DIY rewiring?
Hiring an electrician to rewire a whole home typically costs $8,000 to $15,000. But if you DIY, you can rewire an entire house for $2,000 or less!
Is it legal for me to do my own electrical work?
Most jurisdictions allow homeowners to do their own electrical work without a permit, but check your local regulations to be sure. Some areas require permits and inspections for home electrical work.
What size wire should I use to rewire my house?
For most 15 or 20 amp general lighting and outlet circuits, use 12/2 Romex. For higher amperage appliance circuits, use thicker 10/2 wire. Call an electrician if you are unsure what gauge wire your home's electrical system requires.
Can I really rewire my whole house safely in a weekend?
Yes, with good planning and by following proper safety procedures like shutting off all home electricity, you can safely rewire an entire house in 1-2 days. Work carefully and get help if needed.Never rush through electrical work.
What do I do with all the old wiring I remove?
Check with your local recycling and waste disposal centers. Some accept old copper wire for recycling. Otherwise you can cut it up and throw it away in trash bags. Just make sure to dispose of it properly and safely. Don't let wire scraps pile up around the house!
Let me know if you have any other questions! I hope this gives you the confidence to tackle rewiring your home. The satisfaction of doing it yourself is huge!
