Cooled air leaving through the fireplace

An air-conditioned room loses cooled air through an open flue, because the warmer air in the chimney keeps drawing on the room below it. A damper left open, or one that no longer closes, turns the fireplace into a vent that runs between fires.

A cast throat damper closes metal against metal, so even a good one lets a little air past. A warped or rusted one lets much more. We check the seal with a light from below and tell you whether a new plate will close the gap or a gasketed top seal makes more sense. Feeling a draft near your fireplace in Green Cove Springs?

How chimney damper replacement runs

Handle and plate tested
With the fireplace cold, the control is worked through its travel and the plate checked from below with a light.
Failed part named
Pivots, plate, frame or control, the part that failed is written down with the repair options and prices.
Freed, rehung or replaced
Sound parts are cleaned and freed, a plate is matched to its frame, or a new damper is set at code height.
Travel and seal confirmed
The plate must open fully and close flat under the light before the job is done.

Rotary cranks that seize in Green Cove Springs

Geared damper controls collect rust and soot at the threads and teeth, and away from the ocean the cause is usually water and disuse rather than salt.

We free or replace the drive on Green Cove Springs fireplaces and leave the crank turning smoothly from closed to open.

The light test for a damper seal

The simplest damper test needs a dark room and a good flashlight. With the damper closed, the light is held in the firebox pointing up at the plate, and someone in the room looks for light spilling past the edges. On a bright day the test can run the other way, with daylight from the top showing through the gaps.

We use both, depending on the time of day, and we mark where the gaps are. A gap along one edge points to warp or a bent lip. Gaps all round point to scale on the seat or a plate that has dropped on worn pivots. Each has a different fix.

Dampers behind a wood-burning insert

A wood-burning insert with a liner running up the flue passes through the throat where the damper sits. Insert manuals deal with that directly. Some tell the installer to remove the damper or lock it fully open, so the liner has room and the plate cannot close on it.

So a damper that looks missing or fixed open behind an insert may be exactly what the insert's instructions required. We check the insert's manual before calling it a fault. If the insert is being taken out and the fireplace will burn open fires again, the damper is then restored or replaced so it can close between fires.

Using the fireplace while a part is on order

Some damper repairs need a part ordered, a matched plate or a control assembly that fits the frame. Whether a fire can be lit while you wait depends on where the plate is stuck.

A plate held fully open lets a fire burn safely, though room air escapes between fires. A plate stuck closed or partway closed means no fire until the repair is done. Where we can, we leave the plate secured fully open so the fireplace stays usable while the part arrives, and we tell you which situation you are in before we leave the house.

Before a damper part is ordered

Will a new plate do, or does the whole damper go?

A new plate is enough when the frame is flat, uncracked and has sound pivot lugs, and a matching plate is still made. If the frame has failed, the whole damper is replaced or a top seal is fitted instead.

Why is there a clamp on my damper?

It is probably there for a vented decorative gas appliance, whose instructions require the damper to stay partly open. We leave it while that appliance is installed and remove it only when the fireplace returns to wood.
