DALLAS-FORT WORTH DAMPER REPAIR
A damper stuck open lets your heated air straight up the flue; one stuck shut fills the room with smoke. I photograph the damper where it sits, show you what is wrong with it, and write the repair on an estimate.

The damper is the metal plate above the firebox that opens to let smoke out and closes to keep your heat in. When the handle snaps off, the blade rusts shut, or the frame warps, most people just stop using the fireplace — or worse, burn with it closed and fill the room with smoke. We free stuck dampers, replace broken handles and blades, and fit a top-sealing damper when the old one is past saving.

Common Questions
Often it can be freed. Rust, creosote buildup, and a bent plate are the usual reasons a throat damper stops moving, and those can be cleaned up and adjusted. What decides it is the frame, because that is set into the masonry — if the frame itself is cracked or rusted through, fixing the plate alone will not hold. You will see the photo before I recommend either one.
Close it on a cold, windy day and hold your hand near the opening. If you feel outside air moving, it is not sealing. Daylight around the edge when it is shut is the other giveaway. A throat damper is metal resting on metal, so even a good one was never airtight — the question is how far off yours is.
You can, and plenty of people do, but you are leaving an open hole in the house. Conditioned air goes up the flue year round, and rain and animals have an easier way in. If yours will not close, it is worth fixing — or worth looking at a damper that seals at the top of the flue instead.
