Top sealing dampers
Top dampers close the chimney at the top, not the throat for a much tighter seal.

Chimney Damper Repair New Hope, PA
A New Hope chimney sweep can get a stuck damper working again or replace it with a top sealing damper that closes off the flue at the top. Call (267) 714-1009 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. Because it sits in heat, soot and moisture, it wears out over time.
If a damper will not open, lighting a fire sends smoke straight into the house. 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.
An open or leaky damper lets heated air escape and cold air come down the chimney. Even when they close, many old throat dampers leave gaps along the edges. That is why many homeowners replace a failed throat damper with a top sealing damper.
Chimney Damper Repair is often paired with chimney cap installation and fireplace repair, depending on the cause.

Call nowThe process
What happens during a damper repair
Dampers fail for a few different reasons, so the fix depends on what is wrong.
Look at the plate
The sweep looks at the plate, the frame, the handle and the linkage. Soot and debris around it are cleaned away first.
Clear the frame
The damper frame and plate are cleaned so they can move freely. This alone fixes some stuck dampers.
Repair the parts
Worn parts are swapped and the plate is adjusted to close properly. Parts for some older dampers are no longer made.
Replace if needed
When repair is not practical, a new damper goes in. The choice depends on the fireplace and the chimney.
Test the operation
The sweep tests the damper and checks the draft. You will be shown how to use it properly.
What is included
Common damper repairs
Damper stops
A clamp or stop keeps the damper from fully closing where vented gas logs are used so gases can always escape.
New dampers
Rusted out or warped dampers are swapped for new ones with the right control for your fireplace.
Throat damper repair
Throat dampers that stick or leak are repaired where the plate is still sound.
Linkage repair
Loose or broken controls are replaced for smooth operation.

Chimney Damper Replacement New Hope, PA
When a damper is rusted through, cracked or badly warped, replacement is usually the only option. A new throat damper is possible in some fireplaces, though the opening has to match. A top sealing damper often makes more sense than a new throat damper.
When you call (267) 714-1009 from New Hope, mention whether the damper is stuck, rusted or just drafty. Mention whether the fireplace burns wood or uses gas logs, since gas logs change the requirements. Ask about the pros and cons of each type.

Top Sealing Damper New Hope, PA
Mounted on top of the flue, a top sealing damper seals the chimney at the crown instead of at the throat. You work it with a handle in the firebox attached to a cable running up the chimney. 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. Check that it is fully open before every fire.

What the local climate does to a chimney
Winters here are long and cold, and the heating season usually runs from October well into April. 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, which is how cracks, loose bricks and leaks start. Wind driven rain from coastal storms finds any gap in flashing, too. That is why chimney cleaning in New Hope is usually booked in the fall, before the first cold night.

Chimney Damper Repair FAQ
Can I close the damper when using gas logs?
Vented gas logs need the damper fixed open, usually with a damper clamp, because they produce combustion gases that must escape. Closing the damper with gas logs running can fill the room with carbon monoxide. Working CO alarms are a must with any gas appliance.
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. It is best to have it fixed first.
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.
How does a top sealing damper work?
A top sealing damper is mounted at the top of the chimney and closes the flue with a gasket. A cable connects it to a handle inside the fireplace. It often replaces a failed throat damper.
What causes a damper to stick?
A damper sticks when rust, soot or debris keep the plate from moving. Problems with the control mechanism are another common cause. The fix depends on what is causing the stick.
