Damper work, from handle to plate
Protecting the room during damper work
Damper work loosens soot, and soot travels. Before we start, we lay covers over the hearth and the floor in front of the opening. We manage the opening so dust stays inside the firebox as far as possible.
Tell us about rugs, furniture or finishes close to the fireplace, so we can plan around them. Old parts, rust scale and debris are bagged and hauled away when the job is finished. The room should look the way it did before we arrived, with a working damper as the one change you notice.
Why the throat is no place for hands
The throat above the firebox is tight, dark and lined with rough edges. Rust scale and loose debris can fall when a plate is disturbed. It is not a safe place to reach into without protection and proper light.
You do not need to reach in for us to diagnose the problem. A description of the handle and what you see with a flashlight is enough to plan the visit. Leave the plate where it is if it will not move, and let us check it with the right access and tools.
When cleaning is not enough
Cleaning a damper removes soot, rust scale and debris, and it often restores movement. It does not straighten a warped plate, rejoin a cracked frame or replace a missing lug.
We tell you honestly when cleaning will solve the problem and when it will only help for a while. If a part is beyond cleaning, we say which part and why. That way you are not paying twice, once for a cleaning and again for the replacement it was never going to avoid.
A frame that has worked loose
Over time, the mortar that holds a damper frame in the throat can break down. A loose frame shifts when the plate moves, and the plate then closes unevenly or binds partway.
Resetting a loose frame means cleaning out the old joint and setting the frame again with a mortar suited to the heat. Where the frame is sound, it can often be reused. We explain whether the frame can stay and how much masonry work around it is needed before any joint is opened.

Your damper repair questions in Upper Eastside
Should the damper stay open when the fireplace is idle?
No. When there is no fire, a closed damper keeps room air from escaping and keeps outside air, insects and noise out. Open it fully before lighting and close it once the fire is out and cool.
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 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.
