If you have knob and tube wiring, you should be able to acquire homeowners insurance. Some insurance companies may refuse to insure a home using knob and tube wiring, while others may demand higher rates due to the increased risk of fire.
Knob and tube wiring was one of the first domestic wiring systems, and it was most widespread in residences constructed between 1880 and 1940. The wire is secured to the house framing with ceramic knobs, and it flows through the framing with porcelain tubes. The loom is a fabric or rubber insulation that surrounds the âhot wire.â
- Knob and tube lacks a grounding conductor, making it dangerous in kitchens and bathrooms where water may come into touch with it.
- The insulation around the wiring may have degraded, dried, and cracked over time, exposing the wires.
- Insulation: If knob and tube wire is encased with insulation, heat can build up and result in a fire.
- Improper modifications: Modern domestic appliances, such as televisions, dishwashers, and refrigerators, demand a higher voltage than the items used when knob and tube wiring was first installed. According to the International Association of Certified Home Inspectors, it’s not uncommon to uncover alterations performed by novice electricians in an attempt to satisfy new voltage regulations.
Does homeowners insurance cover knob and tube wiring?
Most insurance companies will refuse to cover a property with knob and tube wiring and other antiquated electrical components. The good news is that if you replace your electrical system, you may get full coverage.
“By replacing knob and tube wiring with modern electrical wiring, you’re making your home a lot safer for your family and avoiding a lot of avoidable dangers,” Friedlander adds. “Another significant advantage is that you will be able to get ordinary homeowners insurance without having to pay an exorbitant premium due of your home’s outdated wiring.”
Is it worth replacing knob and tube wiring?
One advantage of knob and tube wiring over modern electrical wiring is that the copper wire used is often of a higher gauge and diameter. This is advantageous because thicker wires generate less heat as power flows through them. The wiring in older domestic electrical systems that have not degraded in insulation can be left in situ. However, as the wire ages, problems are more likely to arise.
While knob and tube wiring isn’t inherently harmful, it can deteriorate, isn’t up to the demands of modern appliances, and can cause electrical difficulties in your home. If you own an older home with such wiring, you should get it inspected at least once a year to ensure that everything is in working order. To have your home inspected, contact a professional like the electricians at Reliable.
Is knob and tube wiring a defect?
Knob-and-tube (K&T) wiring was a typical style of electrical wiring in buildings in North America from around 1880 until the 1940s. Although some of the anxiety associated with the system is unwarranted, it is deemed antiquated and can be a safety threat.

Does knob and tube wiring meet code?
Electrical Tip of the Day: From the 1920s through the mid 1960s, knob and tube electrical wiring was used in residences, with some exceptions in rural areas. The wire was installed using a combination of porcelain “knobs” and “tubes” as insulators, as indicated by the name. A knob and tube wiring system has the following essential characteristics:
- There is no ground: The circuit just has a hot and neutral wire… there is no ground conductor.
- Wire insulation consists of a rubberized fabric or ascroll fiber insulation wrapped around electrical wires.
- A second rubber/fiber insulator was put over the primary conductors in some circumstances.
- Outside of electrical junction boxes, connections or splices were created by twisting the wire at a “tap” point, soldering the connection, and insulating it with tape.
- Hot and neutral conductors were separated on the framing member: Unlike current romex wire, hot and neutral conductors were not in a shared cable.
- They were divided by framing members on opposite sides.
What you should be aware of. Although the NEC code and most local authorities do not expressly state that knob and tube wiring is banned, they do specify some extremely strict conditions if it is to be left installed and in use (NEC 2008 item 394). The following are the basic guidelines to follow:
- No open splices – original splices may be preserved if soldered and taped.
- Knob and tube wiring must only be supported by non-conductive standoff supports and must not come into touch with combustible objects.
- Knob and tube wiring is only suitable for usage in uninsulated, open environments.
- Insulation of any kind must not be used to cover or conceal knob and tube wiring.
So, what is it about knob and tube that makes it such a serious safety problem today? The lack of a ground, the age of the conductor insulation, changes to the building or original installation (such as how it was spliced), and the addition of building insulation above or around the knob and tube are the main factors. Here are the main points to consider:
- There is no electrical ground because the circuit only has a “hot” and “neutral” conductor, which makes it less safe than a modern grounded electrical circuit. Appliance loads should not be connected to an un-grounded circuit because they use a grounded plug (three prong).
- In most cases, the knob and tube have been damaged “Usable life span” is a term that refers to the length of time that anything Heat damage, decaying insulation, leaks, fractured or missing insulators, nibbling rodents, and damage from being steeped all build up over time. We don’t come across many knobs and tubes that are in safe working order.
- We frequently discover inappropriate new work and open splices “Extensions to the original knob and tube circuits have been introduced.
- According to NEC code, electrical splices must be made in an approved junction box.
- The primary reason for this is to prevent a fire from spreading if the connection fails.
- Knob and tube wiring was designed to be fire resistant since the wires were separated on framing members, suspended in free air between knobs, and ran through combustible materials in ceramic tubes. The knob and tube wires no longer meet code where initial conductors were put in walls or attic floors and later covered in building insulation. Due to their proximity to flammable objects, they can become hotter than planned and provide a fire hazard.
- Switched Neutral: Switching the neutral wire on a knob and tube circuit was standard installation technique at the time.
- Homeowners that have switched neutrals are at a higher risk.
- Even if a switch is turned off, full voltage is delivered to the load (like a light fixture). Voltage fluctuations caused by switched neutrals on a circuit can affect today’s sensitive modern electronics.
- Homeowners insurance: Most homeowner’s insurance policies cover knob and tube wiring specifically.
- In some circumstances, it is required to be removed in order for the policy to remain valid.
- In other circumstances, charges may be raised and/or coverage may be altered.
- If your property uses knob and tube wiring, you should explicitly inquire about how this affects your coverage with your insurance agent.

How much does it cost to update knob and tube wiring?
It is not inexpensive. The typical cost of replacing knob and tube wiring in a two-story home, according to Networx, is around $7,000. It’s critical to choose a licensed electrician and adhere to construction codes. The expense of replacing knob and tube wiring is high, but it is a worthwhile investment.
The replacement involves a complete overhaul of the electrical system. The old knob and tube wiring is removed first by an electrician. The junction box is changed out. The previous fuse box is replaced with a breaker box capable of supplying at least 100 amps. Outlets and fixtures will be changed as well. Finally, the electrical work is completed with the installation of new insulated wire.
Walls, ceilings, and floors may need to be removed to provide access to the old wiring. If there are any other renovations that need to be done, now is a good time to accomplish them. Unless you fix the damage yourself (which you shouldn’t), it must be done by a licensed professional. Reassembling everything can take as long as the replacement, increasing the expense.
The replacement process is time-consuming and consequently costly. Cutting corners leads to more serious issues in the future. The removal of knob and tube wiring by certified personnel ensures insurance coverage. When it comes to wiring, getting it right the first time might save you money in the long term.
What year did they stop using knob and tube wiring?
From roughly 1880 to the 1930s, “knob and tube” was the most cost-effective way to wire a home. During the 1940s, it was gradually phased out, replaced by electrical cables that bundled hot, neutral, and finally ground wires in a single flexible sleeve.
Does Geico cover knob and tube wiring?
If you buy a house with knob and tube wiring, you’ll quickly discover that it’s difficult to insure. Many major homeowner’s insurance companies will refuse to cover a house with this type of wiring. It may be too risky for them to insure homes with wiring that is more than 70 years old and prone to problems.
Alternatively, if the home contains knob and tube wiring, mortgage lenders may find it difficult to approve the loan. In some circumstances, an electrical inspection by a certified electrician is required, as well as written evidence certifying that the house has no imminent issues.
