Chimney Damper Repair Severn, MD
A Severn chimney sweep can get a stuck damper working again by freeing the plate, fixing the linkage or installing a new damper. Dial (443) 899-3081 to talk with a local chimney pro about your damper.
Your damper is the plate or door that controls whether the flue is open or closed. In most masonry fireplaces it is a cast iron throat damper just above the firebox, worked by a handle, lever, rotary knob or poker. Years of heat and moisture are hard on any damper.
If a damper will not open, lighting a fire sends smoke straight into the house. With a fire already burning and the damper stuck closed, ventilate the room, keep everyone clear and call 911 if smoke gets heavy or someone feels ill. Leave the damper open until the fire and embers are completely out.
A damper that is stuck open or does not seal is less dangerous but costly in comfort. Throat dampers also tend to seal poorly over time as the plate warps or rusts. That is why many homeowners replace a failed throat damper with a top sealing damper.
Depending on what the sweep finds, chimney damper repair in Severn, MD can go hand in hand with chimney cap installation and fireplace repair.

What happens during a damper repair
Here is how a sweep usually handles a damper problem.
Look at the plate
The sweep looks at the plate, the frame, the handle and the linkage. The smoke shelf and smoke chamber get a look as well.
Clear the frame
Buildup that keeps the plate from moving is removed. Many sticking dampers just need cleaning.
Repair the parts
Broken handles, pins, springs or chains are repaired or replaced. Parts for some older dampers are no longer made.
Install a new damper
A damper that is rusted through or badly warped is replaced, often with a top sealing damper. The sweep explains the options before any replacement.
Test the operation
The final step confirms the damper opens fully and closes tight. You will learn how to operate any new control.

Chimney Damper Replacement Severn, MD
Some dampers are too far gone to repair, especially when the plate is rusted through or the frame is broken. Throat dampers can be replaced with a new throat damper, but access is limited and fit can be tricky. A top sealing damper often makes more sense than a new throat damper.
Calling (443) 899-3081 from Severn with a quick description of the problem helps the sweep plan. Gas logs and wood fires need different damper setups, so tell the sweep which one you have. You will hear which replacement suits the fireplace.

Top Sealing Damper Severn, MD
Top sealing dampers sit on the top of the flue and close with a tight rubber or silicone gasket. A cable down the flue connects it to a handle mounted inside the fireplace. Some designs combine the damper with a cap and screen.
Sealing the top stops cold air from filling the chimney, which keeps the fireplace area warmer. It reduces water and debris getting in. In very cold weather, the gasket should be checked to make sure it has not frozen to the frame before a fire is lit.

Chimneys in this climate
Cold winters keep fireplaces, wood stoves and oil burners working for half the year or more. The hardest thing on brick here is not the cold itself but the constant swing above and below freezing: water soaks into brick, mortar joints and the crown on a mild day, freezes overnight and expands, and each winter widens the cracks a little more. Wind driven rain from coastal storms finds any gap in flashing, too. Most homeowners in Severn, MD schedule a sweep in early fall, and a repair check after a hard winter.

Chimney Damper Repair questions
What causes a damper to stick?
Rust, soot and creosote buildup are the most common reasons a damper sticks. Problems with the control mechanism are another common cause. A sweep can clean it, repair the parts or replace the damper.
How does a top sealing damper work?
Top sealing dampers sit on top of the flue and seal it with a rubber or silicone gasket. You open and close it with a handle attached to a cable. Many models also act as a cap.
Can I close the damper when using gas logs?
Gas logs that are vented require an open damper, typically secured with a clamp. Closing the damper with gas logs running can fill the room with carbon monoxide. Keep CO alarms in the home and follow the manufacturer instructions for the logs.
How long should I wait to close the damper after a fire?
The damper should stay open until there are no embers left, often many hours after the fire dies down. Embers still give off carbon monoxide, so closing early is risky. When not in use, a closed damper keeps drafts out.
Can I use my fireplace if the damper is broken?
If the damper is stuck closed, lighting a fire will push smoke and carbon monoxide into the house. If it is open, the fire will draft but heat escapes when it is not in use. It is best to have it fixed first.
