Smarter Fireplace Performance Starts with a Healthy Damper

A faulty fireplace damper can waste energy and compromise safety—think of it like leaving a window open with a fan pulling warm air out of your home. In this video, Century Chimney explains chimney damper and flue door repair, how to check if your fireplace damper is working, and which upgrades can improve comfort and efficiency.We clarify what a damper does (it’s the door that regulates smoke leaving the home), when to open and close it (fully open while burning, fully closed only when the fire is completely out), and how to inspect it. Lie back, use a flashlight, and look up to confirm the damper is open before you light a fire. If the throat damper right above the firebox is off its track or not operating, we can often reset it; if needed, we repair or replace the damper.For modern upgrades, we commonly install a top-mounted cap-and-damper in one, with a pull cord into the fireplace. It’s stainless steel and guaranteed for life—including labor. This upgrade helps reduce heat loss and can lower heating bills by sealing the flue when the fireplace isn’t in use.If your fireplace damper isn’t working properly, or you’re interested in an energy-efficient upgrade, we’re here to help.
