Need To Have Your Damper Repaired Or Replaced? We Can Help!

One of the first things you do when getting ready to enjoy a fire in your fireplace is open the damper. For decades, this component of the chimney has been installed in the throat of the chimney, just over the firebox (hence, the name throat damper), and its purpose is to close off the flue when the fireplace or stove is not being used and open the flue when you’re ready to enjoy a fire. Unfortunately, throat dampers can rust or get stuck as a result of moisture and creosote deposits and these dampers are also prone to misalignment, making their seal imperfect and making them difficult to open and close.

If the damper wasn’t such an important part of the chimney, this might not be a big deal, but if the damper doesn’t work properly, it can pose a serious threat to the performance of the fireplace or stove, the comfort of your home, and to the health and safety of your family. Here’s why:

  • By opening up the flue, the damper allows proper draft to be achieved and draft is crucial to appliance performance. If the damper is partially closed or completely closed when you go to light a fire in your fireplace or stove, draft will be inhibited and your fireplace or stove won’t be able to get the air needed to work properly.
  • By closing off the flue when your fireplace or stove is not in use, the damper works to keep moisture and outside air from making its way down into your fireplace and home. It also works to keep the air you’ve heated or cooled in order to keep your home comfortable from exiting through your chimney. This means that when it’s stuck in the open position, you’ll have downdrafts, possible moisture problems, and you’ll be paying to heat or cool air that’s just going right up the chimney.
  • By opening up the flue, the damper allows all of the byproducts like smoke and carbon monoxide to exit the chimney — but if your damper is stuck in the closed position, these dangerous byproducts will be pushed back into your home and the air you breathe.

Have you had smoke problems or noticed that your damper isn’t easily opening or closing? It’s time to give Chimspector Venting Specialists a call! It may be that all you need is a simple repair — perhaps your damper has come off its track or is missing a small component that we carry with us in our trucks. If the damage is greater or you’d like to upgrade to a damper that won’t have these types of issues and that will lead to energy savings, we can replace your throat damper with an efficient top-sealing damper.

What’s A Top-Sealing Damper & How Is It Different From A Throat Damper?

A top-sealing damper is a damper that’s installed at the top of the chimney flue rather than in the throat of the chimney. Like a throat damper, it closes off the flue when the appliance is not in use and can be easily opened and closed using a handle or chain. The biggest difference between the two, aside from placement, is that a throat damper provides a less-than-perfect metal-on-metal seal, while a top-sealing damper relies on a rubber gasket to close off the flue. Thus, a top-sealing damper provides an airtight and watertight seal, protecting your flue from top to bottom, eliminating downdrafts, and preventing conditioned air loss. It also serves as a chimney cap, so if you need a new chimney cap and a new damper, you can kill two birds with one stone by investing in a top-sealing damper.
