Back when knob and pipe wiring was state-of-the-art, there were very few electrical appliances in homes. The electricity demand of a modern household will quickly exceed the capacity of an old K&T system. The cost of rewiring a home depends on the size of the house. Expect to pay around $4,000 for 1,500 square feet for materials and labor. Rewiring a home also involves permits, which can cost anywhere from $200 to $900, depending on the needs of your local code. Given the scope of the project, you may want to stay with a friend. Thumbtack says it takes an average of three to 10 days for an electrician to rewire a home. Over time, the wires may sag and hang. This increases the likelihood that they will come into contact with material that could start a fire. If the wires hang from the ceiling of a basement, attic or garage, it could be dangerous to catch something on them.
While a buyer pays for a home inspection, Normandy-Shane says a pre-listing inspection can identify issues such as old wiring, giving homeowners insight into costly repairs. Depending on the location and size of your home, a home inspection costs an average of $337 nationally. True, there is no code that prescribes the complete removal of wiring from knobs and pipes, but experts generally recommend removing as much as possible. Most homes built before 1950 used porcelain knobs and tubes with electrical wiring. The wires were mounted separately on the wooden beam with buttons, with the hot wire mounted on one side of a beam and the neutral conductor on the opposite side of the beam. Other times, the wires are routed 10-12 inches apart in the same area. When the wires had to change direction or pass through a floor beam, the pipes were inserted into a hole in the beam to prevent the wire from touching the wood. The wire was covered with insulation that disintegrates over time due to heat and stress caused by the weight of the wire.
The wiring must be cooled by normal air in the house. Your home`s electrical service center, or circuit breaker plate, distributes power to outlets, switches and appliances. Modern homes require a panel that provides 100 to 200 amps or amps, although some homes with supplements, large garages, or a significant amount of electrical appliances require up to 400 amps. Some homeowners will try to modify an older electrical panel, but doing so incorrectly can result in warm lights, flashing lights, and outlets or switches that work intermittently. I tried doing a bit of research on the internet today and the results scared me and basically convinced me that if the wiring is active, my sale is toast. The buyer uses an FHA loan, so this is a point where they could fail. Plus, I continue to hear horror stories about home insurance companies refusing to insure anything with K&T. When I got my insurance, it didn`t show up, so I didn`t have a problem, but I`m worried if my buyers will have a problem getting insurance and will be forced to withdraw. I easily purchased insurance for a home with a bit of K&T in rural Virginia. See if you can look for companies that insure farms or older homes. The wiring of knobs and pipes dates from the 1800s to the 1930s and suspends wires through ceramic pipes.
As for aluminum wiring, from 1962 to 1972, due to rising copper prices at the time, about 2 million households were wired with aluminum instead of copper wire. Layman`s translation: The absence of a grounding wire in the knob and hose wiring increases the likelihood that you will start a fire if you overload these circuits. I have bought and sold many houses with knob and hose. Then there is no grounding cable with K&T wiring, so the three-pin plugs cannot be used in sockets. The third wire, which is common today, reduces the likelihood of shocks and fires. The hard part of the exchange is getting behind drywall, plaster, etc. So the cost/difficulty of replacement varies greatly, so you need to get a good electrician for quotes. I had two K&T circuits at home. Replaced one for about a grand piano. The other one was quoted at 6 Grand so I left it. From what little you have described, I estimate that your $3 to $4,000 could be.
The only solution for wiring the button and hose is to rewire the house. The cost can range from $4,000 to $15,000. Prices rise in many older homes because the houses were built with plaster walls, making it difficult to drill a hole and repair the walls to increase the price. There are homeowners who have chosen the easiest path and have removed only the visible knob and pipe wiring as in the basement. Therefore, when buying an older home, it is important to have a knowledgeable home inspector who can check the outlets to ensure there is no active K&T wiring in the walls. “The good news is that a properly installed K&T cabling system was largely safe, if not overloaded,” says David Outlaw, director of operations at Onvico Inc., a general contractor and engineering firm based in Thomasville, Georgia. No, you do not need to remove the button and hose. Ask the electrician to cut it where it was exposed between the basement beams.
As long as it is separated at both ends, you do not need to tear or open the walls to remove it. If you`re buying a home with knob and hose wiring, you need to be aware of a few issues. For example, insulation cannot touch wires because heat from wires cannot be dissipated. The wiring of the knob and hose does not provide a third wire for grounding, but only a warm wire and a neutral white wire. Even if two-slot plugs are replaced with three-pin plugs (for appliances that need them, such as kitchen appliances), there is still no third wire that protects against electric shock. The alternative is to leave things alone and bet on a buyer buying the house as is. Of course, this option carries the risk of lowering the asking price or having to wait a long time for the sale. If a seller decides not to upgrade, there is a risk that a transaction will fail.
No matter how much a buyer wants the home, they will have to withdraw if they can`t get insurance. There are many misconceptions about wiring knobs and tubes, which this article will hopefully help dispel. Knobs and piping have been used in homes and buildings for decades. It has been adapted for use with modern devices and is still legal in Canada if installed in accordance with the code. If you have any questions about installing your home`s electrical system or if your home`s wiring complies with current regulations, please contact an electrician for more information! Overall, according to section 12 of the Canadian Electrical Code, wiring of knobs and pipes is legal. Often referred to as open wiring, homes built in the 1930s still have a knob and pipe in place. It is the insurance companies that demand that it be withdrawn. Cabling can`t handle modern equipment and for good reason.
The Ministry of Housing and Urban Development (HUD) states that home surveyors should inspect the electrical box to ensure there are no broken or frayed wires. The main sales guides (Fannie Mae, Freddie Mac & FHA) are suitable for wiring knobs and hoses as long as they work, are safe and in good condition, and measure at least 60 amps. From the buyer`s point of view, it is the difference between an expense that they know needs to be made some time after the move and an expense that must be made immediately to make the home safe and habitable.
