Masonry fireplaces are unique in the fact that every one of them is different. Masonry fireplaces are built on-site to the architect’s specifications by a qualified individual. Sometimes, especially in older homes, the wrong flue size is used or there may be issues with the way the smoke chamber area of the fireplace was built. There are many different ways for a fireplace to be improperly constructed. Any one, or combination of these possibilities can cause your fireplace to smoke back into your home.
Home Pressure Issues
Your whole house works together with all of the appliances as a single system. If the pressure in your house is not properly balanced, it can cause your fireplace to smoke. For a more in-depth look at how house pressure works, read the article “Why does my house smell smokey?”
HVAC Ducting Issues
The heating source of your home may be to blame for your fireplace woes. An improperly placed cold-air return may be causing your fireplace to sporadically smoke back into the house. Maybe there is not enough air supplied to the fireplace’s room, leaving the fireplace unsupported. Smoke Stacks Inc. can help you diagnose the possible causes of your smoking fireplace issues.
Wrong Type/Style of Flue Cap
The rain cap on your chimney can be causing your fireplace to smoke back into the house. There are many types of chimney rain caps available for sale on the market today. The problem with the extensive offerings is that sometimes the wrong type of rain cap is purchased for the chimney. There are specific requirements for rain caps that are installed on chimneys, if your cap doesn’t meet those requirements, it may be the cause of your smoking fireplace issues.

Believe it or not, even the location of your chimney can cause your fireplace to smoke back. If the chimney is exposed on the outside wall of the house, it is exposed to a lot of cold air. This cold air can make the chimney’s structural mass very cold over time. It can take some time to properly heat up a cold flue stack. Cold air in the flue will often sink down into the room and cause your fireplace to smoke because cold air is heavier than warm air.
