How to Stop Fireplace Draft

A warm, crackling fireplace can bring a cozy ambiance to any home during the colder months. However, if you’re experiencing a draft coming from your fireplace, it can not only diminish the comfort but also increase your energy bills. Fortunately, there are several steps you can take to stop a fireplace draft and ensure maximum warmth and efficiency in your home.

1. Install a Fireplace Draft Stopper: A fireplace draft stopper, also known as a chimney balloon, is an inflatable device that fits into your chimney to stop drafts. Simply inflate it and place it securely in the chimney opening. This can significantly reduce drafts and prevent cold air from entering your home.

2. Seal Cracks and Gaps: Inspect your fireplace for any cracks or gaps that may be allowing drafts. Use fireplace caulk or high-temperature silicone sealant to seal these areas. This will not only prevent drafts but also improve the overall efficiency of your fireplace.

3. Add Glass Doors: Installing glass doors on your fireplace can help prevent drafts and provide an extra barrier between your home and the outside air. Make sure the doors are properly sealed to prevent any air leaks.

4. Install a Top-Sealing Damper: A top-sealing damper is a device that sits at the top of your chimney and seals it when not in use. This can prevent drafts from entering your home and also help keep birds, debris, and rain out of your chimney.

5. Insulate Your Chimney: If your chimney is not properly insulated, it can be a major source of drafts. Consider adding insulation around your chimney to reduce heat loss and stop drafts. You can use insulation sleeves or chimney wraps specifically designed for this purpose.

6. Close the Damper: One of the simplest ways to stop a fireplace draft is to make sure the damper is closed when the fireplace is not in use. This will prevent cold air from entering your home. Remember to open it before lighting a fire.
