A home may need rewired if it was constructed more than 50 years ago, if residents smell burning odors or hear crackling from inside the walls, if outlets and switches appear burned or discolored, if circuit breakers trip frequently, or if fuses blow often. During rewiring, an electrician tears out old copper and aluminum wires and replaces them with a plastic-coated alternative. This replacement reduces the risk of a house fire, which affects nearly 26,000 U.S. homes each year.
Houses built between 1880 and 1939 often have knob and tube wiring, which provides air flow between wires and lumber through the use of ceramic tubes and knobs.
