Faulty Electrics


This is one of the most dangerous of all the common faults as electricity can cause serious injury or even death. Faulty wiring is one of the biggest issues; bad earth can prevent appliances working or leave you vulnerable to shocks.

You need to check all the sockets and other outlets to ensure that the wiring has not become loose, or corroded. It is also a good idea to visually inspect all your appliances for issues.

As well as faulty sockets you need to check the wiring in your breaker box and check that all the circuit breakers work properly.

In addition, pests can chew through wiring in the walls, creating shorts and increasing the risk of fire.

It is generally safer for a home inspector or qualified electrician to check all the wiring for you; they’ll be able to run circuit tests to ensure the cables you can’t see aren’t damaged.
