Damper repair from the handle to the plate
What a chimney damper does for your home
The damper is the metal plate that opens the flue when a fire is burning and closes it when the fireplace sits idle. Open, it lets smoke leave the house. Closed, it keeps cooled indoor air from drifting up the chimney and keeps outside air, insects and noise from drifting down.
When the damper stops opening or closing properly, the fireplace either smokes or leaks air all year. Our technicians check how your damper moves, how it seals and what is holding it back, then give you a written estimate for the repair or replacement at no charge.
A damper is a simple part, but it works every day. Even when the fireplace is idle, it keeps the flue closed and the house sealed. That is why a damper that has quietly stopped closing can cost comfort for months before anyone notices.
Debris sitting on the damper
Leaves, twigs, loose mortar and bits of nesting material fall down the flue and land on the damper plate. Enough of it keeps the plate from opening or closing all the way.
Our technicians clear the debris from the plate and the smoke shelf behind it, then check where it came from. A missing or damaged cap usually lets it in, and animals in the flue are handled separately and humanely.
What lands on the plate can also include rust flakes and grit from the throat itself. If we find a lot of it, we look for the source, such as a deteriorating smoke chamber or a damaged flue, and note it on the estimate.
When an alarm sounds near the fireplace
A smoke or carbon monoxide alarm going off while the fireplace is in use is an emergency. Get everyone out of the house and call 911 from outside. The damper can wait.
Once the fire department has cleared the house, call us to find out what happened. A damper that dropped shut, a jammed plate or a blocked flue are all things our technicians check, and the fireplace stays unused until the cause is fixed.
After an alarm, keep the fireplace unused until the cause is found and fixed. Test your smoke and carbon monoxide alarms regularly and replace batteries as needed. A working damper and working alarms together make the fireplace far safer to use.
Cast iron and steel dampers
Fireplace dampers are made of ferrous metal, cast iron or steel, because they sit in the heat of the fire. The code calls for a ferrous metal damper in masonry fireplaces.
Those metals rust when water reaches them, so a good replacement is only half the job. The other half is keeping rain off it, which is why our technicians look at the flue cap on every damper visit.
Metal dampers also expand with heat, and one that fits too tightly can bind during a fire. Our crew leaves the right clearance so the plate moves freely when hot and seals when cool.

Damper answers for Bryn Mawr homes
I can see daylight around the closed damper. Is that a problem?
It means the plate is not closing all the way, usually because it is warped, something sits on its seat or the control stops short. Cooled air slips out through that gap on hot days. We find which cause it is, fix it and look for light again before we leave.
Can I light a little newspaper to see whether the damper is open?
Please do not. If the damper is shut or jammed, that smoke comes straight into the room and can stain the fireplace face. Leave the fireplace cold and book the free inspection, and our technician checks the plate directly.
