Damper repairs and replacements for Harbordale
Our workmanship warranty on damper work
The damper work we complete is covered by our workmanship warranty. It applies to the parts we freed, re-hung or replaced, and the written record of the work lists them.
If a repair of ours does not hold as it should, tell us and we look at it again. The terms for your job are explained before you approve the work, so you know what they cover from the start. Keep the written record with your fireplace papers, since it shows which parts the warranty concerns.
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.
Dry wood keeps the damper cleaner
Wet or unseasoned wood burns cool and smoky. That smoke leaves more deposits on the throat, the damper plate and its pivots. Over time those deposits stiffen the pivots and hold moisture against the metal.
Burning only dry, split wood is one of the simplest ways to keep a damper moving freely. Seasoned wood is lighter and sounds hollow when two pieces are knocked together, and wood that smokes heavily is likely too wet. Mention the wood you usually burn when you call. It helps explain what we find on the damper and what to change afterward.
Children and pets during damper work
Damper work happens inside the fireplace, with tools, dust and loose parts close by. Keep children and pets out of the area until the job is done and the room is clean again.
We keep our work area tidy and the opening covered when we step away. If the job runs over more than one visit, the fireplace is left in a safe state between visits. We tell you whether it can be used in the meantime or should stay out of service.
Lines you will find on the damper estimate

- Free written estimate before any work
Before you approve damper work
Is it normal for a fireplace damper to show some rust?
Yes. A damper sits where heat and moisture meet, so light surface rust is common. Deep scale, pitting or holes are not normal. They usually point to water reaching the plate from above.
What does the free inspection look at on my damper?
We check the plate, frame, pivots and control, how far the plate travels and how it seats. We also look at the smoke shelf and throat. You get the findings explained and a free written estimate.
Is damper repair covered by a warranty?
Our workmanship warranty covers the work we did on the damper. If our repair does not hold as it should, tell us and we come back to look at it. Ask us to explain the terms for your job before you approve.
