Chimney Damper Repair & Replacement
The damper seals the flue when the fireplace isn't in use. A damper that won't open, won't close, or won't seal wastes energy and lets outside air and moisture in.
Open when you burn, closed when you don't
A working damper lets smoke out while you burn and seals the flue afterward so conditioned air doesn't escape up the chimney. Rust, warping, and broken hardware are common reasons an older damper stops sealing or sticks in place.
Repair or upgrade
Depending on the problem, we repair the existing damper or replace it — including top-sealing options that close off the flue at the top. The right choice depends on the fireplace and the condition of the current damper.
Signs of a damper problem
- A damper that won't open or close fully

Frequently asked questions
Why is cold air coming in with the damper closed?
An old throat damper often warps or rusts and no longer seals. Repair or a better-sealing damper can cut that draft.
Can a damper be replaced without a full fireplace rebuild?
Usually, yes. Many damper problems are solved by repairing or replacing the damper itself.
