Image Text: There may be times, especially if your house is more than 40 years old, when you need to upgrade electrical wiring for safety, or because the existing wiring no longer meets your family’s power needs. Faulty wiring is the leading cause of residential fires, and the older your house is, the greater the chances that the wiring might be outdated or unsafe. Rewiring can be a messy and expensive proposition, but with a little upfront planning you can minimize the disruptions and even turn the job into an opportunity to add features that will increase the value of your home.
