Almost all fireplace dampers are the same, a cast-iron contraption located at the top of the firebox. Many homeowners assume that these dampers are the only type. However, there’s another option and you may want to consider it. Here’s what you need to know about chimney dampers and why you should install a top-sealing damper in your home.

The Problem With Traditional Chimney Dampers

Most chimney dampers use a basic technology. A metal ring or exterior surrounds the opening of the chimney flue at the top of the firebox. A flap either folds or twists to fit into that damper when it is closed and your fireplace is not in use. The problem with these types of dampers is that they are highly inefficient, and they become burdensome over time.

Due to the extreme heat of the fireplace, metal fireplace dampers warp over time and fail to form a tight seal. The warping can also impact the mechanics of the damper, causes it to get stuck or make it difficult to open or close. Once your chimney damper fails, your chimney lose a significant amount of air when not in use. This also makes it easier for cold drafts to make their way down your chimney.

The Solution to Inefficient Dampers: Top-Sealing Dampers

If your traditional throat chimney damper has failed or is allowing cold drafts into your home, the best solution is to get a top-sealing chimney damper. A top-sealing damper is fitted to the top of your chimney, rather than placed inside. These dampers feature rubber gaskets to allow the damper to seal off the chimney entirely when your fireplace is not in use.

When you install a top-sealing chimney damper, a cable runs down the interior of the chimney. The damper is opened or closed with the pull of a chain or a lever. You’ll also notice that warm air is sealed inside your home, while water and cold drafts will never find their way in again. It will also help your chimney flue to block off wild animals and debris!
