The way we handle damper installs in Lake Whippoorwill
Details our Lake Whippoorwill team explains on every top damper visit.
How it differs from the damper at the throat
A throat damper is a metal plate just above the firebox that pivots open and shut. Cast-iron throat dampers close metal on metal, and as they warp and rust, small gaps open around the plate.
By contrast, a top-sealing damper closes the whole flue at its outlet on a gasket, and it also keeps rain and debris out of the flue above the throat. During the inspection we explain which of the two suits your fireplace, and we put the reasoning in writing so you can weigh it at your own pace. Many homes end up using both, with the old throat plate left open and the new top damper doing the sealing.
Clamps, stops and removed plates
The same appliance manual says that if its clamp does not fit or cannot give the required opening, a permanent stop can be installed, the damper blade removed or the damper cut to leave the minimum opening.
Those options exist so a gas appliance always has its opening. They are the opposite of what a top-sealing damper is for, which is why we treat a fireplace with a decorative gas appliance as a separate conversation rather than a routine damper job. If you are unsure what is in the firebox, we identify it during the free inspection before anything else is discussed.
Open area under a cap
Section R1003.9.3 of the Florida residential code sizes the open area under a rain cap on a masonry chimney at four times or more that of the flue outlet below it. A cap that crowds the opening slows the smoke leaving the flue.
When a cap sits over a top damper, we check that the lid opens fully under it and that the cap leaves the flue its open area. Both details are part of the fit check before the unit is ordered. If a cap would crowd the lid, a different model or cap style is proposed before anything is ordered.
Questions worth asking before you approve
Does my fireplace suit a top damper? Is anything in the firebox that needs the flue held open? What happens to the old throat plate? Where will the handle go, and is a cap included? Asking them up front helps you compare our proposal with any other quote on the same terms.
Our specialists answer these before you approve, and the answers become part of the written scope. A damper installation should hold no surprises. If any answer changes during the work, you hear about it before anything else happens.

Top damper questions from Lake Whippoorwill
Short answers from our damper team in Lake Whippoorwill. 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.
When can I close the damper after a fire?
Only once the ashes are completely cool. The Consumer Product Safety Commission advises keeping the damper open until then and never closing it at bedtime over warm ashes.
