What is a chimney cap?

A cap is just that, it fits on top of your chimney and it is open on the sides. The function of a chimney cap is to keep animals, birds, and debris out of your chimney and home. They are open so they allow air to follow in and out. Chimney caps also provide a barrier and keep loose sparks from landing on your roof.

What is a damper?

The damper is located in your masonry chimney. Dampers function to seal off the chimney flue. The damper seals your fireplace shut when you are not using the fireplace and allows smoke to be vented outside when you are using your fireplace. If you ever filled your room with smoke when starting a fire in your fireplace, you learned the importance of opening the damper! The Chimney Safety Institute of America provides an in depth explanation and description regarding the anatomy of your chimney.

Why a top sealing damper?

When someone asks us why they should have a top sealing damper, the question is easily answered in five words: Top Sealing Dampers Reduce Utility Costs!

Since heat rises, if your damper does not close or seal properly all your heated air will escape from your home and drive your utility costs sky high. In addition, if you don’t have a damper that seals properly you will wonder why you continually feel drafts and are always cold. Another sign you need a tight fitting damper is when your house can never be cool enough in the summer.

Creating a tight seal at the top of your chimney enables you to keep the cold air from outside from coming in your house and also keeps the warm air in your house from escaping outside.
Top sealing dampers also provide a barrier to prevent debris, rain, snow, and even animals and birds from coming down your chimney into your home.

There are many styles, sizes, and types of dampers.

There are many different styles and types of dampers. Which damper is right for you depends on many factors. The size of your chimney, the age, and the problems you experience and want to prevent. There are a variety of styles and looks of top sealing dampers to coordinate with the esthetics of your home and roof. Prices also range from basic to multi-functional.

Once you chimney professional does a thorough inspection of your chimney, they will make their recommendations to you for your consideration. Together, you and your chimney professional, can evaluate your options, budgets, and choose the right top sealing damper to fit your chimney.
