Dealing with Draft Problems in Your Chimney

Perhaps you were never able to use your fireplace, or you used to, but it started backing up smoke into the house. When the smoke and hot air fails to escape through the flue, your fireplace and chimney are said to be experiencing drafting problems. A wide variety of issues can lead to drafting problems, and oftentimes, they completely baffle and frustrate homeowners.

One easily resolved cause of smoke back up is a closed damper. The damper assembly acts as a door to allow smoke and hot air to escape through the flue when a fire is burning and to keep the furnace-heated air inside from escaping when the fireplace is not in use. If the damper stays closed during a fire, the smoke has nowhere to go except into the house.

Another common drafting problem is an obstructed flue. Animals like birds, raccoons, or squirrels seek out the warmth and safety of the chimney during cold, winter months. These animals and their nests will partially or completely block off the flow of smoke through the flue. A chimney service can install a chimney cap for an affordable price to prevent animals from nesting in the flue.

An obstructed flue can also be caused by the buildup of creosote, a tarlike compound created by burning wood. A health threat in and of itself, creosote also builds up inside the flue and may eventually seal it completely. To prevent this and the other dangers of creosote, have a mason sweep your chimney at least once every year.

Your chimney can also experience drafting problems when the firebox and flue do not fit together properly. The size of the flue compared to the size of the firebox should follow a 10:1 ratio, meaning that for every 10 square inches of firebox, there should be 1 square inch of flue opening. If the flue size cannot accommodate the volume of smoke produced by the fire, the smoke will back up into the house.

Additionally, the flue should be positioned deep inside the firebox, and the fire should be built as far back as possible. If the fire sits too close to the interior opening of the firebox, it will never have a chance to enter the flue before seeping into the house instead. This could become an issue if the firebox was installed improperly or if it was not manufactured according to fire safety codes. A mason can help you make the right choice in addressing this issue.
