The answer to 'what is rewiring' is the process of replacing a home's existing electrical wiring system with new, updated wiring. This is often done to upgrade an older home's electrical system to meet current safety standards and accommodate modern electrical needs, such as increased power demands from appliances, electronics, and smart home devices.
Rewiring typically involves removing the old wiring and installing new cables, outlets, switches, and other electrical components throughout the home. This can be a complex and labor-intensive process, so it's generally recommended to hire a licensed and experienced electrical contractor to handle the work.
