How we fit a top sealing damper in Sunset
Drop-in dampers recessed into the flue
Where a standard top-mounted damper will not sit properly, some makers offer a drop-in design. It is recessed a short way down the flue rather than sitting on top of it, and it can work under a rain cap or a cap kit.
Drop-in dampers still come with product limits, including exclusions for flues venting decorative gas appliances. We look at whether a drop-in design suits your flue and cap arrangement. If it does, the estimate explains why it was chosen over a top-mounted model.
Measuring the flue for a top damper
Top dampers come in sizes and shapes to suit common flues. The measurement that matters is the flue opening and the tile around it, including the tile's shape and how far it stands above the crown. A damper sized by eye from the ground rarely fits.
We measure during the free inspection and record the figures on the estimate. Where the flue falls between standard sizes, we explain which adapter, if any, the maker offers for it. The damper you approve is then the one that fits your flue.
Cleaning the flue before the damper goes on
The damper frame bonds to the tile top, and the flue beneath it is about to be closed off at the top. It makes sense to clean the flue first. One damper maker recommends having the chimney cleaned when the damper is installed, to help make sure the flue is in good working condition.
Cleaning is priced on its own, apart from the damper, and you can take it or leave it. We tell you what we saw in the flue and whether cleaning is needed before bonding the frame. We will not seal a dirty tile top and hope it holds.
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.

Before you add a top damper in Sunset
Does the chimney need cleaning before installation?
The frame bonds to the top of the flue tile, so the tile has to be clean and sound. If the flue holds deposits or debris, cleaning comes first as a separate item. We explain what we saw before you decide.
Can a top damper keep animals out of the flue?
When it is shut, the lid and gasket close the opening that animals use. It must not be fitted over an animal already inside, so we check the flue first. If something is living there, removal comes before the damper.
Does your warranty cover a top damper you install?
Our workmanship warranty covers the installation we carry out, and we go through its coverage with you before the work is agreed. The damper itself carries its maker's terms, which we pass on with the written record of the job.
