The fireplace damper controls airflow through your chimney — open it when burning, close it when the fireplace is idle to prevent conditioned air from escaping up the flue and outside air from flowing in. A damaged, corroded, or missing damper is a significant source of energy loss in Westminster homes, and a damper stuck in the closed position can cause dangerous smoke and carbon monoxide backup into your living space. Simmons Brothers Chimney Sweeps diagnoses and repairs throat dampers and installs top-sealing dampers as a superior alternative for both new installations and replacement of worn-out traditional dampers.
Traditional throat dampers — located just above the firebox opening — are commonly made of cast iron or steel and are subject to rust and warping over years of heat exposure. When the metal corrodes or warps, the damper no longer seals properly, wasting energy year-round. Top-sealing dampers are a popular upgrade we install in Westminster: mounted at the top of the chimney like a cap, they seal with a silicone gasket that dramatically outperforms the loose metal-on-metal contact of old throat dampers. Top-sealing dampers also prevent animal and debris entry when the fireplace is not in use. Our technicians can assess your current damper during a routine cleaning or inspection visit and recommend the most cost-effective repair or replacement solution.
