What Is A Top-Sealing Damper Cap?

A top-sealing damper cap is a damper that’s installed at the top of the chimney (where you would traditionally have a chimney cap), rather than down in the throat of the chimney system.

Placing the damper up at the top of the chimney is beneficial for several reasons:

  1. Top-sealing dampers keep water, animals, and birds out — With the damper all the way up at the top of the chimney, you’ll enjoy added protection against moisture damage and animal entry. Simply close the damper when your fireplace is not in use, and the damper will keep rain, snow, sleet, birds, and animals out of your chimney flue.
  2. Top-sealing dampers keep conditioned air in & outside air out — Even the newest throat dampers don’t provide an airtight seal, but top-sealing dampers rely on rubber gasketing, not metal-on-metal like traditional throat dampers. This completely eliminates downdrafts and keeps conditioned and heated air inside of your home, where you want it. In fact, homeowners typically enjoy enough energy savings that their top-sealing damper caps essentially pay for themselves in just a year or two.

We Install The Most Attractive & Effective Damper Caps On The Market

Here at Sweeps & Ladders, we’re proud to offer the very best damper caps to our customers in Nashville, Brentwood, Franklin, Green Hills, and the neighboring communities. Here’s a little bit about each type we offer and what makes each so great:

Lock-Top Dampers

Lock-Top energy saving dampers mount to the chimney flue and seal tight with a silicone rubber gasket. When not in use, they’re very low-profile, and when opened, they simply pop up and look much like a typical metal chimney cap. They feature a drop down cable that makes opening and closing the damper easy and convenient, and when closed, these dampers provide a completely airtight seal. That means, no heat or air conditioning lost up your chimney, no downdrafts, no rain, and no pests in your chimney. Lock-Top dampers are made of cast aluminum, stainless steel, and silicone rubber gasketing, and carry a lifetime warranty.

National Chimney's Premier Damper Caps

The Premier damper cap from National Chimney looks much like a traditional chimney cap (but it’s a little bit larger), which means it provides great protection from rain, snow, and sleet. American-made and constructed of stainless steel, these damper caps are built to last and, like Lock-Top dampers, carry a lifetime warranty. They also feature a cable and handle that make it easy to open and close the damper, but instead of popping up like the Lock-Top damper, when opened, the Premier damper cap’s rubber seal over the flue simply opens up. You’ll be able to see these damper caps even when they’re closed, but National Chimney offers them in standard stainless steel, as well as powder-coated options (like black, brown, copper, and custom colors).
