Can You Rewire A House Without Removing Plaster & Drywall

It is easy to overlook the electrical wiring in your home that enables you to use your appliances, equipment, and lighting without a second thought. While you may not have noticed, the wiring and electrical system can become outdated over time, and this is when a house rewire may be necessary. 


A house rewire involves replacing all the wiring to ensure that your home is safe and efficient. This involves a lot of work and should be done by a certified electrician to ensure it is proper. So, if you’ve noticed that your lights are flickering, or that the circuit breaker is constantly tripping, then you may need to consider a house rewiring.

How to Rewire a House Without Removing Plaster and Drywall

Have you ever wanted to rewire a house, but weren’t sure how to do it without having to remove the plaster and drywall? You’re not alone. It’s a common question from homeowners. Fortunately, rewiring a house without removing plaster and drywall is possible!


Here’s what we do –

Plan & prepare the stage

Here at Charlie Sparks, we take special care when it comes to planning and preparing for the stage of any project, no matter the size or complexity. Whether remodelling or rewiring an entire/part of a home, we always look for ways to get the job done without causing any unnecessary destruction. In the case of rewiring a house, we like to explore the possibility of avoiding the removal of plaster and drywall to save time and keep costs down. 


Our team of professionals have extensive experience in this area, and they know exactly how to get the job done without causing any destruction. We know that your home is important to you, and that is why we take extra care when it comes to working in your home.


We usually start by –

  1. Checking the blueprints of old wiring so that new wiring can be more efficient. 
  2. Redesigning according to your requirements, taking into consideration the drywalls and plaster
  3. Calculating the rough figure of the wire needed for new work while having a backup.

Pre-work Stage

Planning and preparing the stage may look easy, but here’s where the intensity changes. Doing the pre-work stage is paramount for any project. Not only does this step create sufficient room for wiring, but it also gives you a general idea of the requirements and necessary steps that will be required to complete the project.


Even more importantly, preparing and doing the pre-work stage helps you locate any crawl spaces that need to be shut down or re-considered. It is critical to ensure that everything runs smoothly and that all safety measures are well-regarded. Taking the extra time to do the pre-work upfront makes a world of difference when it is about completing the project.

Removal Stage

So next, we take on the task of filtering the entire house! It’s not as simple as just unplugging the whole system, because you could end up getting yourself into a lot of danger. Even though you may think it’s a straightforward procedure, there can be hidden risks that need to be considered before attempting anything. It’s important to be very careful and take the necessary precautions to avoid any accidents or injuries.


We discuss whether to pull off the complete cable or not. It can be tricky to make the call, as we want to make sure you’re safe, but also don’t want to cause any unnecessary damage. Usually in difficult situations, we recommend only dealing with the visible wires and leaving the interior ones untouched – after all, it’s best not to mess with things you can’t see.


What’s interesting is that this cautionary approach has been applied to all kinds of situations for centuries, not just dealing with cables. It’s a fascinating testament to the power of human intuition and the instinct to be careful. In any case, it’s important to remember that safety comes first.

New Wiring Stage

The majority of the rewiring process isn’t as straightforward as it may appear at first glance. It requires precise calculations and techniques to make sure that the job is done properly and safely. In many cases, the old wiring will have to be replaced with new wiring, but that isn’t always the case. In some cases, there may be a need to precut the area of every electrical circuit’s device to accommodate the new wiring. And if that isn’t enough, the electrical current must be monitored at all times to ensure that any changes made to the wiring are following safety regulations. It’s a tedious and involved process, but one that must be done right if you want to avoid any potential disasters.

Most of the work needs at least two people who are accustomed to working in these conditions and can work competently together. So, if you are thinking of doing electrical work yourself, considering the dangers accompanying it, we recommend you consider an expert for the job.

Tips for Rewiring a House Without Removing Plaster and Drywall

  1. It is always better to calculate the accurate length of wire needed along with the fixtures and keep some extra length as a backup.
  2. Rewiring a home requires the efforts of a duo; it is not something that one person can work on.
  3. If you are thinking about working on it, you need the right preparation and attention to detail. There are specific components you should know about and certain safety measures that you should take.
  4. If you’re tackling a project that might feel daunting, it’s only natural to wonder if you can do it all alone. From saving you from making costly mistakes to offering advice and guidance on how best to tackle the task at hand, having an expert on your side can be invaluable. So, if you’re feeling overwhelmed or unsure of what to do next, why not give an expert a try? You’ll be glad you did! 

Frequently Asked Questions

If you are wondering if it’s truly possible to take on a project without the help of an expert, the short answer is, yes, you can. But all things considered, it is best to leave it to the professionals. After all, when it comes to something as important as an electrical project, it is better to be safe than sorry! An expert will have the knowledge and experience to complete the project quickly and efficiently, with minimum hassle. This way, you won’t have to worry about making mistakes or running into unexpected problems. You can save time, and have value for your money when you work with experts.
After a thorough inventory, check local codes and permits. Decide whether you want to run just electrical, or data, fire, and security to make a detailed work plan. Keep a watch on existing infrastructure. Follow instructions carefully to avoid mishaps and electrical hazards.
If your home has been your happy abode for more than 25 years, then it’s perhaps time to look into a full rewire. It’s a wise course of action to stay on top of, and we recommend it as a part of keeping your home in the best shape it can be.
Start by carefully removing the damaged area with a trusty utility knife, and then apply a premixed drywall compound to patch it up. After allowing the patch to dry, smooth and sand everything down to a perfect finish. And of course, don’t forget to prime and paint where necessary – the perfect touch to make your wall look as good as new!
