Damper repairs and replacements for Riverland
Sizing a replacement damper to the throat
Throat openings vary in width, depth and shape, and replacement dampers come in set sizes and styles. A damper that is too small leaves gaps around its frame, and one that is too large will not seat at all.
We measure the throat and the old frame during the free inspection, so the estimate names a part that will fit. Where no standard damper fits the opening, we explain the options openly rather than forcing the nearest size. You see the chosen part on the estimate before anything is ordered or removed.
Very hot fires and the damper plate
A cast damper plate sits right above the flames. Very hot fires, such as those fed with scrap lumber or large loads of paper, can warp it. Once warped, it may not seat properly again.
Burn dry, seasoned wood in a fire sized for the fireplace. EPA guidance on wood burning favors dry wood and warns against burning trash or treated wood, which can damage the appliance and release harmful chemicals. Those habits protect the damper, the firebox and the flue together.
Water on the damper after heavy rain
If you find water, rust stains or damp debris around the damper after heavy rain, the water is entering higher up. The damper is simply where it lands.
Tell us when the water appears and roughly how much. We check the damper for rust damage and note where the water seems to come from. The source is a separate repair, often at the top of the chimney. Fixing the damper alone would treat the symptom and leave the cause in place.
Check the damper with the fire out
The damper should be tried and checked with the fireplace cold. A hot damper can burn hands, and a fire under a damper that suddenly moves can spill smoke into the room.
That is how we inspect it, and it is how we suggest you check it too. Open and close it slowly, watch the plate with a flashlight and listen for grinding. If anything seems wrong, leave the damper alone and describe what you saw when you call. A clear description saves time on the visit.

Throat damper questions, answered plainly
Is it safe to light a fire if the damper only opens halfway?
No. A plate that stops partway narrows the passage and tends to push smoke into the room. Leave the fireplace unused until the plate opens fully and the cause has been found and repaired.
Is there a discount when I book damper work promptly?
Yes. Damper work you book inside 72 hours of your free inspection is 10% off, along with any other service in that booking. The inspection and written estimate are free whether or not you book.
Could the damper be why my room smells of old smoke?
It can be one reason. A plate that does not close lets air drift down the flue and carry the smell of old deposits with it. We check the seal and the deposits and explain whether the damper is the cause.
