A chimney damper is crucial to the efficiency and safety of your fireplace. It controls the airflow and smoke through the chimney flue and has a big impact on your entire chimney system. When closed, it acts as a tight seal, keeping outside air out and inside air in.
When open, it allows carbon monoxide-rich exhaust to escape through the flue, which is necessary for starting and controlling a fire. Dampers play a key role in keeping a warm home and safely directing toxic smoke outside.
By letting GMT Home Services handle your chimney damper repair, you can rest assured that your chimney will work properly and that your home will be warm and safe all year round.
Chimney dampers come in two main types: throat dampers and top-sealing dampers. Throat dampers are traditional fixtures found in masonry chimneys with a cast iron or steel handle that lifts a large metal plate. Top-sealing dampers, also known as top-sealing chimney dampers or cap dampers, have a small spring-loaded door inside the cap at the top of the chimney. Top-sealing dampers have advantages over throat dampers: easy access and the ability to prevent debris and animals from entering the flue. They also retain warm air in your home for better energy efficiency.
Chimney dampers also allow you to control and throttle your fires. Using the notches on the damper handle, you can adjust the airflow after you have established your fire. But be careful if the damper is only half open; it will let smoke and fumes into your home.
If you are sure no smoke is escaping, a throttled damper can save energy by reducing heated air loss and keeping your home warm without overworking your furnace. Knowing when to open and close your chimney damper handles is key to safety and efficiency. Always keep the damper open while the fire is burning to allow smoke and toxic gases like carbon monoxide to escape through the flue. Close it only after the fire has cooled to prevent outside air from entering and warm air from inside. For chimney damper repair and maintenance, call GMT Home Services.
To determine if your damper is in the open position or closed, you can do a visual inspection, check the controls, or feel for drafts.
Visual Inspection: For a throat damper, look directly at the damper plate. If it’s fully open, you should be able to see into the chimney flue. If it’s partially open, adjust the handle to widen the view. Be aware that maintenance issues may prevent the plate from opening fully.
Check the Controls: If you have a top-sealing damper, look at the handle. If the chain is hanging, the damper is closed; if it’s latched or hooked into a notch, it’s open. Many dampers also make a loud thud sound when closed, so that’s a bonus.
Feel for Drafts: Put your hand in the firebox and feel for cold air. If you feel a draft coming down the flue, the damper is open.
If your damper won’t open, it could be damaged, off-track or blocked by debris. Operating a wood or gas fire with a partially functioning damper is dangerous, so you should call a chimney technician if you have any issues.
Chimney dampers can accumulate debris, soot and creosote, which must be cleaned for safe operation. High temperatures can warp the frame and plate, so be careful. Never use a fireplace with a broken damper until a professional has fixed it.
Regular maintenance is key to your damper, and annual inspections prevent costly repairs. If it’s been over a year since your last chimney service or you have concerns, call GMT Home Services to schedule an inspection and ensure your system is operating safely and efficiently.
If you have a gas fireplace with a standing pilot light, you need to know about the throat damper. This damper has a damper stop to prevent it from closing fully and leaving a small gap for venting toxic gases like carbon monoxide.
Carbon monoxide is a silent killer often mistaken for flu symptoms like nausea and headaches. If trapped indoors, it can be deadly as your body will absorb it in excess of oxygen.
To be safe, install carbon monoxide and smoke detectors on every floor, especially near bedrooms. Call GMT Home Services for professional damper repair and maintenance to make your gas fireplace safe and efficient!

Yes, a damper can be repaired. Common issues are misalignment, damage, or blockage from debris. In many cases, chimney technicians can fix these problems and get the damper functioning properly and safely. But if the damage is severe or the damper is old, it may be more cost-effective to replace it.
A chimney flue damper controls the airflow through the chimney. When the damper is closed, it acts as a seal to keep outside air from entering the home and inside air from escaping. When opened, it allows smoke and gases from the fire to exit through the flue. This control is critical for proper drafting and to prevent backdrafts of smoke and toxic gases into the living space.
Yes, a chimney damper is necessary for safe and efficient fireplace operation. It controls airflow, reduces heat loss when the fireplace is not in use and prevents animals and debris from entering the chimney. A functioning fireplace damper contributes to energy efficiency and reduces the risk of chimney fires by ensuring exhaust gases are vented properly.
The damper should be open when a fire is burning in the fireplace so smoke and gases can escape. It should be closed when the fire is completely cool and not in use. This keeps indoor air quality and prevents unwanted drafts when the fireplace is not in operation.
The best damper for your chimney depends on your situation and chimney design. Top-sealing dampers are recommended for energy efficiency and to keep debris and animals out of the chimney. They seal tight when closed to reduce heat loss. Throat dampers are traditional and work well in masonry fireplaces but may allow more air to escape when closed. Choose a damper that fits your chimney and fireplace for the best performance.
Regular inspections are key to maintaining your damper. Check to make sure it’s working, clean the damper and flue tile to prevent debris buildup, and lubricate the moving parts of the damper for smooth operation. For better energy efficiency, consider a top-sealing damper. A lock-top damper reduces drafts in wood fireplaces, and a seal-tight damper prevents moisture and heat loss.
