How to Rewire a House

The rewriting of the house is more important than applying the new paints and design to your house. Regardless of the reason, it’s a wise idea to rewire the house, especially if your house is 40+ years old. 

Despite the old age of the house, here are some other reasons that include rewiring of the house.

  • If your wires have been there for a long time and you’re experiencing high electric bills. 
  • Getting bright lights from the LEDs is also dependent on the quality of wiring. 
  • You’re having terrible joints
  • If the battens and sockets are transmitting weird smell (highly advisable)

If you’re experiencing similar situations, and have no idea about what the next steps are, don’t worry. We’ve got your back.

This article only includes the detailed steps of rewiring of the house. It’ll help you to get the overall process of what it takes and how complex or simple this actual process is. 

Let’s dive in.

Step 1: Plan and Prepare Stage

You can’t escape the planning and preparation stage while considering any type of project. And the same goes with the hose rewiring project as well. Any minor miscalculation or ignoring factor can cause you a tonne of time and resources. 

This is why it’s highly advisable to spend much time on planning about the circuits and needs of electric sockets. 

You can even move one step further and take the help of a professional. It’ll help you out throughout the whole planning process. Here, you need expert’s suggestions, and ideas to make everything feasible and correct.

Wondering how to begin the planning correctly? It usually involves these steps.

  • A complete blueprint of old wiring: To make things work for you again, it’s important to have the older idea. Having the previous wiring circuit will help you to make better changes
  • Make a new blueprint out of it: After considering the older circuitry, it’s time to redesign it according to your needs.
  • Calculate the wire needed: You must come up with the rough figures. Consider taking some extra length for backup. 

Step 2: Prep Work Stage 

Here comes the step where the real work needs to be done. This step is all about locating places and attics about the new wires to get into. Clearing all the possible confusion right away. You’ll not have to remove the complete drywall. 

In that case, you have two options, either make crawl space for the new wiring or find the space from the attic. Both the options vary depending on the situation and according to your house. 

The prep work stage is essential for the whole thing. It allows you to create sufficient room for wiring but also gives you an overall idea about the requirements. And most importantly, you’ll get to know about the crawl areas and what needs to be shut down.  

Here, the important thing is to mark down the crawl areas, where the electrician will work the most. 

Can you do this all along yourself? Well, if you’re already indulging in electrician stuff and confident, go for it. Although, make sure to remove the clutter and debris near the electric outlets as well. 

However, it’s highly recommended to take the expert’s help. You’ll get more advantage shifting furniture and making crawl areas. 

Step 3: Removal Stage

This step includes the filtration of the complete house. But, it’s not as easy as it sounds. There are certain complexities. It’s never a good idea to just start unplugging the whole system. You can even get yourself into a big accident as well.

When it comes to the expert he decides whether to pull off the complete cable or not. Mostly in difficult situations, only the visible wires are taken out. There’s no need to alter the interior wires, as it’s not wise to deal with things you can’t see.

On the other hand, in the crawl or important areas, there will be no options left but to take out complete circuitry. There are also some cases where the wiring is easily replicable. In such cases, the electrician tapes new wires with the old wires to replace the circuit with new wires. 

Step 4: New Wiring Stage

The majority of the rewriting process is not as simple as replacing the new wires with the older ones. It requires precise calculations and techniques to make things favorable. Moreover, in some cases, there will be a need to precut the area of every electrical circuit’s device.  

The next sub-step includes drilling of the openings. Around the dimension of ¾ inches of holes will be required in the top plate of the wall for every opening. Make sure, this process is done by two people.  One shall catch the wires coming out from the crawl space, while the other should deal with the laying of these cables properly. 

Some Additional Tips

  • To get an accurate idea of the wire needed, there’s a simple rule behind it. Calculate the total wire length of the whole circuitry including the fixtures. The same number is what you’ll need during the rewiring process. 

However, it’s highly advisable to consider some extra length for a convenient wiring process. Chances are you’ll commit some mistakes or might’ve to wind up some wire in certain places. 

  • Willing to put in all the effort on your own? Well, again it’s suggested that you should leave the process for the experts, until and unless you’re one. Moreover, rewriting the house is always the job of at least two people. 

Don’t forget to bring another expert in case you’re willing to indulge in the process.

  • It’s always a wise idea to have paper joint tape and joint compound with yourself. There are high chances that the drywall from some area of the house might get affected in the rewiring process. 

To patch the drywall again, you’ll require these materials. Patch the small holes in the drywall by covering it with paper joint tape. The next process includes applying a joint compound. Give an hour or two for the compound to dry properly, don’t touch it before that. 


We hope the above information will give you concrete estimates for the rewiring of your house. The next steps involve doing it (by taking the help of experts). Moreover, you shouldn’t delay this. The quicker the rewiring will happen the better it will be for your house. 

Lastly, don’t forget to take safety measures, cut off the complete electric supply before even starting the whole process.
