How Do I Know if My Fireplace Flue Is Open or Closed?

Fireplaces are a cozy addition to any home, providing warmth and ambiance during the colder months. However, to ensure proper ventilation and prevent any potential hazards, it is essential to know if your fireplace flue is open or closed. Here are some ways to determine the status of your fireplace flue:

1. Visual Inspection: The most straightforward method is to visually inspect the flue. Look up into the fireplace chimney with a flashlight to see if there is a visible barrier or obstruction. If you can see daylight or a clear passage, the flue is likely open.

2. Check the Damper: The damper is a metal plate that controls the airflow in the flue. If the damper is open, it means the flue is also open. To check, simply reach up into the fireplace and feel for the damper handle. If you can move it easily, it is likely open.
