9 Things That Fail a Home Inspection

Electrical Issues

Minor electrical issues are typically not a dealbreaker for most home buyers, but significant problems, such as outdated knob-and-tube wiring and aluminum wiring, can be costly to repair.

While many homes still have aluminum wiring, it’s not always problematic. However, aluminum branch circuit wiring, which powers outlets, switches, and fixtures throughout the house, is a major concern. Aluminum wiring tends to expand and contract significantly during use, which can cause connections to loosen over time, increasing the risk of fire. If this issue is identified, it’s advisable to have an electrician conduct a thorough inspection.

Addressing wiring problems can be complex and costly. It often involves either replacing the wiring entirely or redoing all connections where the wires start and end. Rewiring a 1,500-square-foot home can cost an average of $7,000 nationally.

Knob-and-tube wiring also requires removal and rewiring of either part or all of the home.
