One of the most common problems with fireplace is a smoky chimney. As the fire burns in your fireplace, you find your home filling with smoke. If your chimney is drafting properly, you should not notice any smoke in your home. However, if your fireplace does fill your home with smoke, it’s time to evaluate and resolve the issue. Smokey fireplaces are a nuisance, and they can degrade your indoor air quality. Here are some of the most common causes of chimney draft issues. At A to Z Chimney Services, we are here to troubleshoot any smoky issues for you!
Stuck or damaged damper
Your chimney’s damper regulates the air flow of your chimney. If your home is filling with smoke when a fire is burning, the chimney damper often is to blame. The chimney damper could be stuck closed, preventing smoke from rising out of the chimney altogether, or it may not be opened fully. A partially closed damper can restrict the air exchange through your chimney, causing improper draft and filling your chimney and home with smoke.
A dirty chimney can also be a culprit of causing smoke to enter your home. If the chimney flue is restricted because of a buildup of creosote, the chimney won’t draft properly and smoke can fill your home. If your chimney has been recently cleaned, and your fireplace is suddenly smoking without another explanation, it’s still important to call a sweep. This often means an animal or debris could have made its way into your chimney, creating a blockage that prevents smoke from exiting your home properly.
Missing chimney cap
Your chimney cap plays a role in keeping smoke from entering your home when a fire is burning. The chimney cap prevents bursts of air from flowing down your chimney, blowing smoke back into your home. Sometimes, solving chimney draft issues are as simple as installing or replacing a chimney cap.
Cold chimney flue
If your fireplace smokes when a fire is first lit, but the smoking seems to subside once the fire gets going, your chimney might just be too cold. When dense, cold air fills the chimney, it can block smoke from drafting up and out of the chimney. This is often a problem for homes whose chimneys are on an exterior wall. You can solve this problem by warming your chimney before lighting a fire. Twist tight logs of newspaper and light one end. Hold the burning newspaper in your fireplace at the base of the chimney flue. Repeat this with two or three pieces of newspaper, and your flue should be adequately warm to allow proper drafting.
Improperly sized chimney
In some cases, chimney draft issues have to do with the chimney construction itself. If the chimney flue is too wide or narrow for your firebox, or if it is too tall or short for your fireplace, your chimney won’t draft properly and your home will fill with smoke. The only way to restore a proper chimney draft is with professional intervention. Most of the time, we can resolve the draft with a new chimney liner or a chimney extension.
