Can I fix my own light switch safely without an electrician?

You can replace a basic light switch yourself, but we recommend a licensed electrician for safety and code compliance. Miswiring can cause shocks, tripping breakers, or fire risk. Blue Line Electric provides an $89 diagnostic with a whole-home electrical health check and same-day repair when possible, performed by licensed, insured electricians who follow Texas electrical codes.

Quick checks:

• If you notice burning smells, heat, or buzzing, stop and call for service.
• If breakers trip or lights dim after a switch change, stop and call.
