Becoming the owner of an older, heritage style home, can be thrilling, but also incredibly challenging. If your house was built prior to 1950, you’ll need to consider the type of wiring the home has, for instance, copper, aluminum, or knob and tube. If it is an older house, and it has never been completely rewired, it could have knob and tube wiring. If this is the case, it’s quite likely you’ll have a problem when you begin shopping around to get house insurance.
Any of the problems listed below can cause short circuits or overheating. To avoid these problems, you may need to replace your house’s wiring. If in doubt, have an electrical inspection done.
Your insurance company will always want to know what type of wiring your home has. They’ll want to know if the entire house has been wired this way, or if some of the home has been updated. They may require you to have an electrician inspect the wiring, before they can offer you home insurance. A number of problems can occur when only part of the house has been rewired, and the rest of the home still has knob and tube. The connections between the two systems may expand and contract at different rates, causing connections to become loose.
Also, knob and tube wiring runs on a 60 amp service, but most insurance companies will require your home to have a 100 amp service/ breaker panel.
There are companies that will refuse to insure you with knob & tube wiring, as they consider the risk to be too high. However, there are others that will insure your home, perhaps with a higher premium or higher deductibles. There may also be a requirement to have an electrical inspection done by a professional before coverage can be offered.
