Top-Sealing Damper Installation in Aubrey, TX

A throat damper is a cast-iron plate resting on a cast-iron seat; it never really seals, which is why an idle fireplace still bleeds conditioned air all summer. A top-sealing damper mounts at the crown instead and closes on a rubber gasket, sealing the flue like a lid at the top rather than a loose plate at the bottom. A stainless cable runs down to a handle at the firebox so you still control it from inside, and while it is shut it doubles as a rain and animal cap. Price follows flue size and shape plus roof access. It pairs naturally with the insulation and duct work we already do, so the whole house holds its temperature better.
