The smoke that escapes from your fireplace into your house is a result of poor drafting (air moving in an upward or downward direction), or something blocking the way of the draft. We often ask why is fireplace smoke in my house?
A poorly, drafting chimney allows smoke from the fireplace to enter the room rather than exhausting it to the outside. A blockage in the chimney prevents drafting in the same way that a closed nozzle at the end of a hose prevents water flow. The air being pulled (draft) up your chimney works under the same scientific principles as water flowing in a hose, and it corresponds to the amount of pressure in a water hose. The only difference is that the air pressure is negative, and the water pressure is positive. Similar to the way a kinked or plugged hose stops water flow, a poorly drafting chimney is the result of an airflow restriction.
This can be caused by a of multitude of factors such as: excessive creosote build-up, closed or plugged dampers, improper construction, structural damage, chimney height in relation to peak roof height, home renovations, excessive bird nesting materials in the flue, or even a dirty chimney cap. The following are some of the possible reasons and solutions for the undesirable fireplace smoke in your house.
Is the Damper Open?
Heat rises, and if your damper is closed, the fireplace smoke will come in the house. Many people leave the damper closed when the fireplace is not in use. A common mistake is forgetting to open the damper again before lighting a fire.
The damper is a hinged, metal plate used to seal the fireplace when not in use, and to regulate a fire in the fireplace by controlling the flow of air (draft) coming in the chimney.
To open the damper, you usually have to crouch down and peer upward toward the rear of the fireplace. A flashlight will help. A metal lever inside the fireplace controls the damper. Pushing on the lever opens it, and notches along the length of the lever allow you to adjust the opening to get the draft needed for the fire to burn without fireplace smoke backing into the house. The correct procedure for using a damper is to open it fully before lighting the fire, then close it a few notches after the fire is well under way by moving the lever with a fireplace poker. If the fireplace smoke begins to come in the house, reopen the damper a notch at a time until the smoking ceases. After all the embers have burned completely, close the damper.
Open a window
Another common cause of fireplace smoke in the house is insufficient air in the room containing the fireplace.
Try opening one or two windows in the room a few inches while the fire is burning. This will increase the draft in your chimney by bringing more air(oxygen) in to the fire, which should allow it to burn hotter.
Energy efficient homes are better insulated and keep out cold drafts; however, a negative side effect is that there is often not enough outside air coming in the house for a fire to burn hot enough to rise through the flue or to cause drafting, which carries that hot air up the chimney. The chimney flue becomes the source of make-up air so that as air is drawn down the flue, it picks up smoke from the fire and delivers it into the living area. Cracking a window eliminates this negative pressure.
Inspect your chimney for blockages
If you’ve opened the damper and smoke still fills your home, there may be a blockage in the chimney itself. Common culprits include:
Outside debris: Leaves, twigs, or other debris can obstruct airflow.
Animal nests: Birds or squirrels might have nested in the chimney, creating a barrier.
To address these issues, consider hiring a professional chimney sweep. They can safely get on the roof and inspect the chimney for any external obstructions. A certified professional will not only clean the chimney but also ensure it’s free from potential blockages that can disrupt the airflow and cause smoke to enter your living space.
By addressing both internal and external airflow issues, you can effectively reduce smoke in your home and enjoy a cozy, smoke-free fire.
Grate Placement
The fire must always be made in a grate to provide enough air flow around the logs. Without a fire grate, the fire will smoke and not get hot enough to ventilate properly, thus bringing fireplace smoke into your house.
Sometimes smokiness is a result of the fire being built too far forward in the fireplace. This causes smoke to enter the room instead of going up the chimney. The remedy is to build the fire as far back against the rear wall of the firebox as possible.
Use Seasoned Wood
A fire that appears to smolder or make hissing sounds while burning, most likely has a high water content. It simply can’t burn hot enough for the hot air to rise up the chimney flue and get replaced by cooler air. The smoke and gases will not be able to exit the room.
You will have to go without a fire unless you have well-seasoned wood that has been split for a minimum of six months (the longer the better), and stored in a covered and elevated location. A piece of seasoned wood will be lighter (in weight) than the same size, but green (unseasoned, newly cut) piece of wood. It will sound hollow when hit against another piece of wood. Green wood will also be lighter in color and generally have a stronger, fresher smell to it, while seasoned wood will usually appear darker and have little odor. Seasoned wood can also be identified by cracks on the end of the logs.
Stacked Wood Placement
Build your fire with larger pieces of wood on the bottom, leaving gaps for air to circulate between the wood. Continue stacking wood with each layer going crisscross to the previous layer, and decreasing in size. Wad up some newspaper and stick it under small pieces of kindling and wood chips on the top of the stacks of wood, then light the paper. This will produce a hotter fire more quickly, and it will burn cleaner because smoke won’t have to pass through cold logs. This method will keep smoke going up the flue and out of the room.
Competing Appliances
Many factors influence a home’s airflow including interior mechanical systems, fuel burning appliances, such as furnaces, fireplaces, wood stoves, and water heaters.
Make sure no exhaust fans (kitchen, bath, attic fans) are running while you have a fire. Also make sure all of the air vents in the same room as the fireplace are open if you have an air-forced furnace running, or else the return air vent will suck air from the fire, possibly bringing fireplace smoke into the room. Central vacuums can also create depressurization by removing large volumes of air from the house.
Addressing Air Pressure in Newer Homes
In newer homes, the issue of tightly sealed environments can create competing air pressure problems. When using your fireplace, consider cracking a window nearby. This simple action breaks the seal and balances the house pressure, ensuring smoke travels up the chimney rather than lingering indoors.
Solutions for Older Homes
Older homes often face air pressure challenges due to excessive escaping air. One common culprit is poorly sealed attic doors, which allow air to escape through the attic space. To counteract this, check the seal on attic doors and consider adding extra insulation. This can help maintain a balanced air pressure, optimizing fireplace performance.
By tackling both the structural and appliance-related factors affecting air pressure, you can ensure a smoke-free and efficient fireplace experience.
Wind Factors
If you think of your chimney as a straw, in the same way as sucking fluid up through a straw, your fireplace chimney sucks air up through the flue to the outdoors. If you blow through a straw, the air pressure pushes the fluid out of the straw. In the same way, strong winds can push air down your chimney causing smoke to enter your house if you are burning a fire in the fireplace.
This can be a real problem in homes that are located in windy areas, such as a beach house. If that’s the case a cowl on your flue would be better than a cap. A chimney cowl is designed to prevent wind blowing the smoke back down into the room below. They increase the draft of a chimney and prevent back flow.
Why Seek Professional Help If Your Fireplace Fills the House with Smoke?
When your fireplace floods your home with smoke, it’s more than just a minor inconvenience; it’s a potential hazard. Here’s why enlisting professional help is crucial:

How Does a Cold Downdraft Affect My Fireplace, and How Can I Create an Updraft?
When a chimney is situated on an exterior wall of your home, it often becomes vulnerable to the chill of the outside air. This results in a cold downdraft, where dense, cold air pushes downward inside the chimney. Such downdrafts are heavier than the smoke from a fresh fire, forcing the smoke back into your living space instead of letting it escape through the chimney.
Creating an Updraft
To counteract this issue, it’s crucial to establish an updraft before lighting a fire. An updraft encourages air flow upwards, carrying smoke out of the room rather than letting it linger. Here’s how you can achieve this:
Light a Starter Fire: Use materials like crumpled newspapers that ignite quickly.
Warm the Flue: Hold the lit newspaper up the chimney. Tools such as a fireplace poker can help you safely reach into the chimney. This act helps warm the air column, reversing the cold downdraft into a rising updraft.
Use Caution: Always handle fire safely. Utilize appropriate fireplace tools or wear fireproof gloves to protect yourself during this process. If you’re unsure of how to proceed safely, consulting a professional is a prudent step.
Remember, creating an updraft not only improves the efficiency of your fireplace but ensures a safer, smoke-free environment in your home.
