Older homes have a unique charm newer structures usually can’t match, but that old-fashioned craftsmanship often comes at a price. For instance, outdated electrical systems can be inefficient and even dangerous, especially when trying to supply the power needs of a 21st-century household. Below are a few key issues electricians look for in older homes.

3 Electrical Problems Common in Older Homes

1. Knob & Tube Wiring

Before 1935, most houses were wired using a knob-and-tube system, which features ceramic components to secure electrical lines. Unlike today’s three-wire systems, knob-and-tube lacks a ground wire, which increases the risk of an electric shock. The rubber insulation also degrades over time, putting your house at risk of an electrical fire. In fact, the risk these systems pose is so great most insurance companies refuse to cover homes with knob-and-tube wiring.

2. Aluminum Wiring

Many houses built in the 50s and 60s feature aluminum wiring, which doesn’t conduct electricity as well as copper. These wires can easily overheat, especially if they’ve been improperly modified in the past. If your house was built in the 60s, it’s a good idea to have an electrician examine the wires for signs of damage or overheating.

3. Fuse Boxes

These days, most houses have circuit breakers instead of fuse boxes. However, the old fuse models will still work, but a fuse with the incorrect amperage can damage the insulation, creating a hidden fire risk even if the mistake was made 50 years ago. If your home features a fuse box, have it checked by an electrician and consider upgrading to a circuit panel.
