Top sealing damper choices explained
A damper that closes the flue at the top
A top sealing damper is a hinged lid mounted on the top of the flue. A gasket around its edge presses against the frame when it is shut. A cable runs from the lid down through the flue to a handle inside the fireplace, so you open and close it from the room.
Because it closes the flue at the top rather than just above the firebox, the whole flue sits behind the seal when it is shut. Rain, leaves and animals stay out, and so does outside air. When the lid is open, the flue works as it did before.
Why we do not promise energy savings
Damper advertising often includes large energy-saving claims. We do not repeat them. The real effect depends on the house, the climate, how the fireplace is used and how well the old damper sealed. No product label can measure those.
What we offer instead is a damper that suits your fireplace, fits the flue and seals when closed. If comfort or cooling costs are part of your reason for asking, tell us. We explain what a sealed flue top changes and leave the arithmetic to your own bills.
What to mention when you call about a damper
Start with what burns in the fireplace, even if it is rarely used. Then describe the damper you have now: whether it opens, closes, leaks or has gone missing. Mention anything else that vents through the chimney.
It also helps to know whether there is a cap on the chimney and whether any work has been done up there recently. If you have heard animals in the flue, say so. Those details shape the visit, the parts we bring and whether a top damper is even the right conversation.
Mixed metals on a damper near the coast
A top damper often combines metals: an aluminum or stainless lid and frame, a stainless cable, a brass lug, springs and anchors. In salty coastal air, where unlike metals touch and stay damp, one of them can corrode faster than it would alone.
Near the coast, we look at which metals meet on the damper you choose. Where the maker specifies matching hardware, we use it. On an existing damper, corrosion at the hinge or spring is one of the first things we check, since those small parts can fail before the lid does.

Before you add a top damper in Boulevard Park Isles
Where does the handle go inside the fireplace?
A bracket is anchored into the firebox wall on the side you find easier to reach, and the cable passes through it to the handle. We drill with a masonry bit and set the anchors carefully to avoid cracking the firebrick.
What does the free inspection look at for a damper?
The fireplace and its current damper, the smoke shelf, the flue and its tile top, the crown and any cap. We also ask how you use the fireplace. You then receive a free written estimate with the options.
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.
