Why does my home have flickering lights?

Flickering can have several causes: loose light bulbs, a faulty light switch, an overloaded circuit, loose wiring connections, or voltage fluctuations from the utility company. Start by tightening bulbs and testing different switches. If entire rooms or multiple lights flicker together, you may have a loose connection in your panel or a circuit that is nearing capacity. Persistent flickering warrants an electrician visit.

Why It Matters

While a loose bulb is an easy fix, flickering across multiple fixtures can signal a serious wiring issue that needs professional attention.
