How our crew installs top dampers in Belmere
Details our Belmere team explains on every top damper visit.
What a top-sealing damper is
A top-sealing damper is a lid mounted at the top of the flue that closes against a gasket. A cable runs down the flue to a handle in the fireplace, and pulling the cable closes the lid, while spring tension opens it again once the handle is released.
Because it closes the flue at the outlet rather than at the throat, the whole flue stays shut to rain, outside air and insects while the fireplace is idle. We explain how it would work on your chimney before anything is ordered, so the change from a throat damper is clear. It stays a fireplace you can use whenever you like, with one extra step before each fire.
Stopping downdrafts while the fireplace is idle
An open flue lets outside air fall down the chimney and into the room, often carrying the smell of old soot with it. A worn throat damper does little to stop that flow.
A closed top damper shuts the air path at the top of the flue. It will not fix a draft problem while a fire is burning, which has other causes, but it does stop air moving down an idle chimney. If the draft comes from somewhere else, such as a door or a vent near the fireplace, we say so.
Outside air carrying flue odors
When outside air falls down an idle chimney, it can carry the smell of old soot into the room, especially when the house is closed up. A throat damper that no longer seals lets that happen.
Closing a top damper shuts that flow at the top. If the odor comes from something else, such as deposits that need sweeping or water in the flue, we tell you that instead of selling a damper. Honest advice here saves you from buying a damper that does not solve the smell.
Cable length on taller chimneys
Top dampers are supplied with a long cable so they suit tall chimneys. One retailer's listing for the Lyemance damper, for example, lists a 32 foot stainless steel cable.
Before ordering, we measure the height from the flue top to the handle location, so the cable reaches the bracket with slack to set the clamp. On an unusually tall chimney, we confirm the supplied length is enough. The spare length is kept until the tension is set, then trimmed.

Top damper questions from Belmere
Short answers from our damper team in Belmere. Call for anything not covered here.
Can you fit a top damper on a round flue?
Yes, where a model is made for that size of round tile. We measure the flue top and choose a damper made for its shape rather than forcing a square frame onto a round tile.
Can you install it if animals are in the chimney now?
Not until the flue is clear. Animal removal is handled first as its own service, and the damper goes on once the flue is confirmed empty.
