Top-Sealing Damper Installation in Kerrville, TX
A throat damper is a cast-iron plate resting in a cast-iron frame, and it was never built to seal — even a new one lets conditioned air past the metal-on-metal fit all summer. A top-sealing damper sits at the crown instead, with a silicone rubber gasket that compresses against the flue tile and closes the chimney like a lid. It is operated by a stainless cable running down to a handle in the firebox, and while closed it doubles as a rain cap and an animal guard. We measure the flue termination, seat the unit on the crown, and cycle it under a draft check, so the seal and the open position are both verified before sign-off. Serving Kerrville (2 ZIP codes, 24k residents) and surrounding neighborhoods with same-week scheduling.
