Chimney Damper Repair Burtonsville, MD
A chimney sweep in Burtonsville can repair a damper that is stuck, rusted, warped or no longer seals or replace it with a top sealing damper that closes off the flue at the top. Call (240) 358-7617 to reach a local chimney sweep.
The damper is the movable plate that opens the flue when a fire is burning and closes it when the fireplace is not in use. Many fireplaces have a throat damper mounted above the firebox, while others have a top sealing damper at the top of the chimney. Years of heat and moisture are hard on any damper.
A damper that is stuck closed is a safety issue, because smoke and carbon monoxide have nowhere to go but into the room. If you light a fire and smoke pours in, open windows, keep people away from the smoke and let the fire burn down, calling 911 if smoke is heavy or anyone feels unwell. Never close a damper on a fire or warm embers, since that pushes carbon monoxide into the home.
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. A top sealing damper often solves both the seal and the rust problem.
Depending on what the sweep finds, chimney damper repair in Burtonsville, 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.
Inspect the damper
The technician checks how the damper moves and how well it closes. Soot and debris around it are cleaned away first.
Clear the frame
Buildup that keeps the plate from moving is removed. Many sticking dampers just need cleaning.
Free the plate
The linkage between the handle and plate is fixed so it moves again. Some repairs depend on parts being available.
Replace if needed
A damper that is rusted through or badly warped is replaced, often with a top sealing damper. The choice depends on the fireplace and the chimney.
Final check
The damper is opened and closed several times to make sure it moves smoothly and seals. You will learn how to operate any new control.
What is included

Top Sealing Damper Burtonsville, MD
A top sealing damper mounts at the top of the chimney and closes off the flue with a gasket that seals against the frame. You work it with a handle in the firebox attached to a cable running up the chimney. Many models also act as a chimney cap, keeping out rain and animals.
Because it closes at the top, it keeps cold air out of the whole flue, which can help the fireplace feel less drafty. 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: rain and melting snow soak into the crown and joints, then freeze and push them apart, and each winter widens the cracks a little more. Nor'easters drive rain sideways into flashing and mortar that looked fine in summer. Most homeowners in Burtonsville, MD schedule a sweep in early fall, and a repair check after a hard winter.

Common questions about chimney damper repair
Should the damper be open with 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.
What causes a damper to stick?
Rust, soot and creosote buildup are the most common reasons a damper sticks. A broken handle, a slipped chain or a warped plate can also keep it from moving. A sweep can clean it, repair the parts or replace the damper.
How long should I wait to close the damper after a fire?
Close the damper only after the fire and embers are completely out and the ashes are cold. Smoldering embers produce carbon monoxide that needs to vent. Once the fireplace is cold, closing the damper keeps heated air from escaping.
How does a top sealing damper work?
It is a damper at the top of the chimney that seals the flue when closed. A cable connects it to a handle inside the fireplace. It often replaces a failed throat damper.
Can I use my fireplace if the damper is broken?
A damper that will not open makes the fireplace unsafe to use. A damper stuck open is less of a safety issue but wastes heat and lets in drafts. Get it repaired before the next fire.
