Fireplace Dampers

A fireplace damper is generally located in the throat of the fireplace just above the firebox. It's purpose when open is to allow flue gasses from a fire to vent up into the flue, as well as to seal off cold air from entering your home when not in use.

Leaving a damper open when the fireplace is not in use will allow a huge amount of your homes heat to escape up the chimney. Ensure that your damper is completely shut to limit the amount of heat that escapes, and cold drafts from entering. Installing a top sealing damper is a great way to save on heat loss and energy.

Damper Safety Tip

Before lighting a fire, use a flashlight and look up into the fireplace to ensure that the damper is fully open. Many emergency calls related to a fireplace are related to not properly opening the damper.

Top Sealing Damper

A top sealing damper installed on a masonry fireplace is a great way to save on energy. The damper is installed at the top of the chimney onto the flue with a cable running down and installed into the firebox. When the fireplace is not in use, the top sealing damper allows for a tight seal above which prevents cold air from funneling down the chimney into your home. Some studies indicate a return on investment within 2 years of installation.
