Why You Should Consider Replacing Those Old Knob and Tube Wires

I know that rewiring a home can seem like an expensive and disruptive project, but replacing old knob and tube wiring is something every homeowner should consider. Here's why:

Knob and Tube Wiring is Outdated and Potentially Unsafe

Knob and tube wiring was commonly installed in homes built before 1950. This type of wiring features insulated wires that are separated by ceramic knobs and run through hollow tubes.

While it was suitable for the electrical needs of the time, knob and tube wiring is outdated and potentially unsafe compared to modern electrical systems for several reasons:

So while knob and tube served its purpose in the past, it simply does not provide the level of safety and performance that are expected from modern electrical systems.

Knob and Tube Wiring Limits Home Upgrades

As a homeowner, you likely want the freedom to upgrade appliances, add new technology, and renovate without limitations. Knob and tube wiring severely restricts your ability to modernize your home.

Since the wiring is insufficient for handling high power levels, you may be unable to install:

If you try to add these types of high-draw electrical devices, you risk overloading the vintage wires. Your only option is a full rewire.

Insurance and Resale Value Considerations

Here are two other important considerations when deciding about rewiring:

Home insurance - Many insurers will not cover homes with old wiring due to increased fire risks. Or, your premiums may be much higher. Replacing knob and tube will likely lower your rates.

Resale value - Rewiring before listing a home for sale is advisable. Most buyers will be turned off by an old electrical system and may request rewiring before closing. Having up-to-date wiring makes a home more attractive to buyers.

Estimated Costs of Replacement

I know the cost of rewiring is a major factor in deciding about replacement. On average, for a 2,000 square foot home, you can expect to pay:

While not inexpensive, the investment will pay off in safety, expanded capabilities, insurance savings, and home value. Many homeowners choose to rewire sections of the home over time to spread out costs.

The Rewiring Process and What to Expect

The rewiring process involves:

During the rewire, you can expect:

While disruptive, the project is manageable and the results are worth it!

When selecting an electrician, be sure to ask:

Thoroughly researching electricians will ensure your project goes smoothly.

Is It Time to Rewire?

As I've explained, knob and tube wiring poses many fire and shock risks. If your home still relies on this outdated system, I highly recommend looking into replacement for your own peace of mind. The project will modernize your home for safety and enable you to fully utilize new technology. While the costs are significant, addressing this issue now can prevent serious electrical hazards down the road. Let me know if you have any other questions!
