Chimney Damper Repair & Replacement

With the costs of energy increasing every day, it’s more and more important to make sure you don’t lose any heat and air out of the top of your chimney. A chimney damper seals off the top of the chimney flue while your chimney is not in use. Chimney dampers improve the energy efficiency in your home by keeping the warm or cool air generated by your HVAC unit inside your house.

Chimney dampers come in many designs and in every shape and size.  They serve several purposes, including:

  • Conserving energy.
  • Keeping animals from getting into your home via the chimney flue.
  • Stopping rainwater and other debris from getting into your home.
  • Sealing off the chimney when it’s not in use.

After you burn a fire in your chimney, you can’t close the damper for a few hours because the fire will continue to smolder and the chimney must be ventilated. This means that while your damper is open, your chimney is vulnerable to moisture or to animals getting in. For this reason, it’s important that you also have a chimney cap installed over the damper.
