What comes with a top sealing damper

Rusted throat dampers, and ones that show daylight when closed, let cooled room air slip up the chimney between fires. A top sealing damper moves the seal to the top of the flue, where a gasketed lid closes on a frame glued to the tile and a cable brings the handle down to the firebox. It belongs with our chimney cap replacement work, and a local, family-run crew sizes and fits it after a free inspection.

  • Cable run down to a handle bracket in the firebox
  • Screened housing that works as the cap on a single flue

A top damper on the flue

A top-sealing damper with its lid open sits on the clay flue tile of a red brick chimney.

Installing a top sealing damper

  1. Share your flue size if known

    Call and tell us the flue size if you have it. A free visit confirms it on the roof before any damper is ordered.

  2. Tile measured and checked

    The flue tile is measured on the outside and checked for cracks and for height above the crown, so the frame can seat.

  3. Frame set, cable run down

    The frame is set on the tile with the maker's adhesive, and the cable runs down the flue to a bracket in the firebox.

  4. Lid adjusted, handle shown

    We adjust the cable so the lid closes evenly on its gasket, then show you how to open it fully before every fire.

10% off any service booked within 72 hours of inspection

Order the top damper within 72 hours of the inspection and 10% comes off the install.

A cap, a top damper or neither

A cap and a top damper solve different problems, and a few fireplaces should not get a top damper at all.

Top damper questions

Do I still need a cap with a top-sealing damper?

On a single flue, a model with a screened housing works as the cap whenever the lid is open. Chimneys with several flues still need a cap on the others.

Will a top-mount damper keep my cooled air in?

It closes the flue much more tightly than a worn metal throat plate, so less cooled air rises out of the room between fires. It does not replace sealing other gaps in the house.

Can one be fitted in a single visit?

Usually, yes, when the top tile is sound. A cracked tile gets replaced first, and the adhesive cure time is written on your ticket.

What measurements are needed for a top damper?

The flue opening and the condition of the top tile are checked before a model is chosen. Share any existing measurements when you call (904) 920-5495, but do not climb onto the roof to obtain them.

What comes with a top damper install?

The damper sized to your flue, the cable and bracket, any tile repair and a decision on the old throat damper, all on one upfront quote.

Damper troubles our flue pros fix from the top

  • Daylight around a closed throat damper

    The metal plate has warped or rusted and no longer seals. A gasketed lid at the flue top closes the flue tight instead.

  • Damper handle rusted and stuck

    Heat and moisture have seized the throat plate. We fit a top damper and leave the old one open or take it out.

  • Drafts and odors while the fireplace sits idle

    An open flue trades air with the outdoors all day. A top damper closes it between fires and opens fully for one.

  • Rain or leaves reaching the firebox

    With a screened housing, the top damper also works as the cap on a single flue whenever the lid is open.

Size your top damper with a specialist

We measure the tile, check the crown and quote the right model, and you decide before we order.

Full service details

Moving the damper seal to the flue top

The standard damper in a masonry fireplace is a metal plate in the throat, just above the firebox. It closes metal on metal, it sits where heat and moisture attack it, and once it rusts or warps it leaks even when closed. A top sealing damper moves the closure to the top of the flue: a gasketed lid closes on a frame fixed to the flue tile with adhesive, a spring holds the lid open, and a stainless cable runs down to a handle in the firebox.

Closed at the top, the whole chimney stays out of the weather while the fireplace is idle, and the column of air in the flue stops being an open path between the room and the outdoors.

What the code asks of a fireplace damper

Section R1001.7.1 of Florida's residential code requires a ferrous metal damper in a masonry fireplace, set eight inches or more above the top of the opening. The damper may sit in the fireplace or up in the chimney that vents it, provided it can be worked from the room. A top sealing damper meets that through its cable and handle. A throat damper in working order is left fully open, and one that is rusted loose is taken out so it cannot drop shut.

When a top damper is the wrong fix

The tile decides a chimney top damper installation: it has to be sound and stand high enough above the crown for the frame to seat, and the maker's instructions set the flue sizes, adhesive, cure time and cable length. A decorative gas appliance vented through the flue must have the damper held fully open, as its installation instructions require (these appliances are tested to ANSI Z21.60), and factory-built chimneys take only parts listed for them (R1005.2).
