Top damper installation, step by step, for The Willows homes
What our pros check, and why, on damper installs in The Willows.
What a top-sealing damper is
A top-sealing damper is a lid mounted at the top of the flue that closes against a gasket. A cable runs down the flue to a handle in the fireplace, and pulling the cable closes the lid, while spring tension opens it again once the handle is released.
Because it closes the flue at the outlet rather than at the throat, the whole flue stays shut to rain, outside air and insects while the fireplace is idle. We explain how it would work on your chimney before anything is ordered, so the change from a throat damper is clear. It stays a fireplace you can use whenever you like, with one extra step before each fire.
What happens to the old throat plate
Once a top damper is in place, the cable has to pass the throat freely, and an old plate that swings shut could pinch it or block the flue below the new damper. So the plate is left fully open, fixed open or taken out, depending on its condition.
We explain the plan for your plate before any work starts, and it goes into the estimate. Nobody in the house should later close a forgotten throat handle and wonder why the fireplace smokes, so the handover covers that point too. Where the plate is removed, the frame edges are checked so nothing sharp is left in the path of a sweep's brush.
Checking the seal from the roof
The best place to judge the seal is at the top, where you can see the lid sitting on its gasket all the way around. Light, even contact all the way around the gasket is what keeps rain and air out once the lid is locked.
We look for even contact, no gaps at the corners and a frame fixed down with no openings underneath. If anything is off, the tension or seating is corrected before we come down. The result of that check is noted in your records with the clamp setting.
Rusting caps over old dampers
An old painted steel cap over a flue can rust and drop flakes onto the damper lid or the gasket, which spoils the seal. A worn painted cap can also stain the crown and tile top, which is worth cleaning before a new damper goes on.
When a top damper is added, we recommend a cap made of corrosion-resistant metal if a cap is part of the assembly. Where the existing cap is sound, it can stay, and we say so. Rust flakes already on the gasket are cleaned off before the seal is checked.
