Installing a lock-top chimney damper is a common project among do-it-yourself homeowners. As fireplaces and chimneys age they tend to deteriorate from use, foundation shifting, and weather. This causes the original throat damper not to seal as well as it once may have.

Many times, the fireplace throat damper rusts apart and is non-functional, allowing heat and air from your home to escape through the chimney and vice versa.

In today’s chimney industry, we have top locking chimney dampers that are easy to install, made of stainless steel, and completely seal the chimney flue when not in use. The lock-top chimney damper is a great way to reduce heat and air loss from your home and to keep animals, weather, and debris out.
