Fitting a top damper the maker's way
Lever handles with several positions
Most cable dampers are simply open or closed. Some models use a lever handle with several set positions, so the lid can be held part-way open. The maker describes that as a way to control the amount of draft.
A part-open position is useful only if you understand when to use it. We explain the positions at handover and when the lid must be fully open. If a simple open-and-closed handle would suit you better, say so. We would rather fit a control you will use correctly than one with features you do not need.
When there is no throat damper left
In some fireplaces, the throat damper has rusted through, fallen out or been removed during earlier work. The frame may still be there with no plate, or nothing may be left at all. The flue then stands open all the time.
A top damper is one way to give that fireplace a working closure again. A new throat damper is another, where the throat can take one. We look at the throat and the flue and explain which route suits the fireplace. The estimate prices each so you can compare.
Closing an idle flue when the house sits empty
A house that stands empty for long periods has a flue that nobody watches. An open flue lets in rain, leaves and animals, and the first sign may be a mess on the hearth months later. A sealed top damper, left closed, keeps the flue shut in the meantime.
If you leave the house empty, close the damper before you go and leave a note by the fireplace to open it before any fire. We can check the damper during a maintenance visit before you leave. Tell us how to reach you and how to access the house.
Reaching the flue top without harming the roof
Fitting a top damper means working at the flue top for a while, not just a quick look. We plan the route across the roof before climbing and choose where to stand so the roof covering is not damaged.
Tell us about any fragile areas, recent roof work or known leaks near the chimney. We note the roof condition around the chimney in the findings. Roof damage outside our job is written up in simple terms, ready to hand to whoever repairs the roof.
Checked before a top damper is ordered
- Flue tile top condition
- Adapter for a round or lined flue
- Set time before the next fire
- Firebox protected during drilling
Common questions about chimney top dampers
Should I repair the throat damper instead of adding one on top?
Sometimes that is the simpler route. A throat damper that only needs freeing or a new handle may be worth repairing. One that is warped, rusted through or missing parts may point to a top damper instead, and we price both.
What if my chimney has more than one flue?
The damper goes only on the flue that serves the fireplace. Other flues keep the termination their own appliances call for. We identify each flue before recommending a damper or cap for any of them.
What should I mention when I call about a damper?
Say whether the fireplace burns wood or anything else, what your current damper does or fails to do and whether anything else vents through the chimney. That lets us plan the visit to your home in Nurmi Isles.
