Keeping The Smell Out
And The Heat In!
Dampers seal your chimney and fireplace shut when not in use, keeping the smoky smell of your chimney out and the warm air in.
What is a Fireplace Damper?
A fireplace damper is a metal device which you can open and close your chimney flue. Make sure that it is open before lighting a fire so that you properly vent the byproduct gases and combustible particles. When your fireplace is not active, you want to close your damper to help retain the heat inside your home and keep the smoky smell out.
There are two types of fireplace dampers: throat dampers and top-mounted damper caps.
A throat damper is the metal flap that opens or closes your flue. It’s the most common type of damper, but the least efficient since it is not air-tight. If you reach your hand up the chimney, you can operate the throat damper by pushing or pulling its metal lever. It’s typically located in the throat of your masonry chimney just above the firebox, which makes it still easy to reach.
Top Mounted Damper
Top-mounted damper caps are an excellent replacement or upgrade to your chimney’s flue system. A top-mounted damper cap has a stainless steel lid that closes air-tight against a rubber seal and is operated from inside the fireplace using a simple pull chain. These dampers are superior to traditional throat dampers due to their ability to form an airtight seal, which can help with energy cost savings. They are also usually much easier to see and operate.
How We Can Help with Your Damper
Over a period of time, your damper can become damaged or warped by the consistent exposure to heat. If the chimney hasn’t always been properly maintained, you may also find it difficult to open or close your damper due to a layer of rust or excess creosote. Our technicians can conduct a chimney inspection and help diagnose the problem you are experiencing with your damper and assist with any needed repairs.
