How To Redo Electrical In Old House: Old houses have a unique charm, but they often come with a set of challenges, one of which is outdated electrical systems. According to the U.S. Fire Administration, electrical fires account for about 6.3% of all residential fires. One way to prevent this is by redoing the electrical system in your old house.
Understanding the Basics of Electrical Wiring
Old houses have a certain charm and mystery, but with that comes the responsibility of keeping them safe and functional. Redoing the electrical system in old houses is often crucial to prevent potential hazards associated with outdated wiring and electrical systems. Let’s dig into the basics of electrical wiring and understand why it is so important to redo the electrical in old houses.
The first step to understanding how to redo electrical in an old house is to recognize the common types of electrical wiring found in older homes. Knob-and-tube wiring, aluminum wiring, and non-metallic cable (NM) are all common types of wiring found in homes built before the 1970s. Unfortunately, these wiring systems can deteriorate over time, leading to potential safety hazards such as fire or electrical shock.
Wiring Type | Characteristics | Potential Hazards |
---|---|---|
Knob-and-Tube Wiring | Older system, ceramic knobs, open wiring | Deterioration, fire risk |
Aluminum Wiring | Used in the mid-20th century, prone to oxidation | Fire risk, poor conductivity |
Non-Metallic Cable | Common post-1970s, versatile, plastic coating | Deterioration, insulation problems |
Moreover, if you’re experiencing frequent power outages, flickering lights, or a burning smell, these are clear signs that your house needs electrical redoing. Also, if your electrical system has a lower amperage, it may not be able to support modern appliances and devices, another key indication that your electrical system needs an update.

Preparing for the Electrical Redo
Before diving headfirst into the electrical redo, it is essential to get a professional assessment of your home’s electrical system. A licensed electrician can identify any potential problems, recommend the best course of action, and provide an estimate for the cost and timeline of the project. Remember, while DIY is great for painting walls or building a bookshelf, redoing electrical work is a task best left to the professionals.
Once you have a clear idea of the scope of work, it is time to create a budget and timeline for the project. It is always advisable to set aside a contingency fund to cover any unexpected expenses that may arise during the redoing process.
Finally, prepare your home for the process. Remove any furniture, decor, or other items that may obstruct access to the electrical wiring. It’s also a good time to consider whether you want to make any other home improvements while the walls are open, such as adding insulation or updating the plumbing.

Handling Challenges During Electrical Redo
Renovating an old house usually comes with its fair share of unexpected challenges. This is especially true when it comes to redoing the electrical system. Below are some common challenges and tips on how to handle them.
Managing Plaster and Lath Walls
Old houses often have plaster and lath walls, which can make it difficult to run new wiring. To avoid damaging the walls, it’s best to use a flexible drill bit to create holes for the new wiring. Additionally, fish tapes can be used to pull the wires through the walls.
Dealing with Inaccessible Areas
In old houses, there are often areas that are hard to access, such as crawl spaces or attics with limited space. In such cases, it may be necessary to remove some parts of the wall or ceiling to access these areas. It’s important to plan this carefully to minimize the damage and the amount of repair work required afterward.
Handling Unexpected Issues
When redoing the electrical system in an old house, you may encounter unexpected issues such as damaged wiring, old fixtures that need to be replaced, or inadequate grounding. It’s important to address these issues as soon as they are identified to ensure the safety of the electrical system.
