Your throat damper, part by part
Keeping cooled air in the room
When the fireplace is idle, a closed damper is the part that keeps room air from leaving through the flue. A flue open to the sky lets room air and outside air trade places, and the air conditioning then works against that exchange.
A damper that closes badly cannot do this job well. A throat damper closes metal on metal, with no gasket, so it does not seal tightly even when new. It should still close squarely without wide gaps. If a better seal is your main goal, ask about the options, and we explain what each one can realistically achieve.
Damper parts inside a factory-built unit
A factory-built fireplace is a listed assembly. Its damper, its control and the parts around them were tested as part of that listing. The Florida Building Code asks that such fireplaces be installed to their listing and the manufacturer's instructions.
That means replacement damper parts come from the manufacturer's parts list for your model. A generic plate meant for a masonry fireplace is not a substitute. We find the model information, check which listed parts are available, and tell you plainly if the design has been discontinued.
Keeping the written record of damper work
The written record of the work lists the damper parts and what was done with each. It notes the control type, any part numbers and anything we saw that was left outside the job.
That record is useful later. It helps the next person who works on the fireplace, and it answers questions when a home is sold. If the same fault appears again, the record shows what was done and when. Keep it with the fireplace manual, if you have one, and bring it out at maintenance visits.
A flashlight check you can do yourself
With the fire out and the firebox cool, shine a flashlight up past the opening. You should see the damper plate and whether it is open or closed. Move the control slowly and watch the plate follow.
If the plate does not follow the control, stays tilted or stops short, stop there and make a note. You have learned enough to describe the fault. Avoid reaching into the throat or leaning under loose debris. The rest of the check is ours to do.

Damper repair answers for Nurmi Isles
Can you fit a new damper in a fireplace that has none?
Usually. We check whether the throat will take a new throat damper. Where it will not, a different closure option may suit the fireplace, and we price it separately. You choose once both options are explained.
Will a new throat damper stop all air from escaping?
A throat damper is not airtight. A cast plate closes metal against metal and leaves small paths for air. A good repair closes the plate squarely, without wide gaps or rattle, which limits the loss.
Why does the damper rattle when the wind picks up?
A loose plate, worn pivots or a slack control rod can let the plate move in air currents. We find which part is loose and tighten, adjust or replace it. Tell us whether it rattles with the plate open or closed.
