Replacing a rusted or broken damper assembly.
Learn moreThe damper is the metal plate that opens to let smoke out when you burn and closes to seal the flue when you don't. Damper repair frees up a stuck damper, replaces broken parts, and restores a proper seal so it works as it should.

A damper that won't open is a smoke problem; a damper that won't close is an energy problem, letting heated or cooled air pour up the chimney year-round. Either way, a functioning damper matters for both comfort and safety — and a rusted-open damper can add up to real money on your energy bills.

We determine whether it's stuck, broken or simply corroded.
We free a seized damper and replace failed components.
We make sure the damper closes and seals when you need it to.
If it's too far gone, we'll talk through replacement options.
Moisture from an uncapped or poorly capped flue is the usual reason dampers rust and seize around here, so damper trouble often points to a cap or crown issue too. We'll check the whole top of the chimney, not just the damper, so the fix actually lasts.
Usually rust, warping or debris in the track. We can often free and repair it; if the damper is corroded through, replacement is the answer — sometimes with an energy-saving top-sealing damper.
Yes. A damper stuck open lets conditioned air escape up the chimney all year. Restoring the seal — or fitting a top-sealing damper — stops that loss.
