Chimney Damper Repair DuBois, PA
A chimney sweep in DuBois can repair a damper that is stuck, rusted, warped or no longer seals so the fireplace drafts properly and stops leaking heated air. Dial (814) 913-0171 to talk with a local chimney pro about your damper.
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.
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.
An open or leaky damper lets heated air escape and cold air come down the chimney. 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.
Many chimney damper repair calls in DuBois also turn up a need for chimney cap installation or fireplace repair.

How chimney damper repair works
Here is how a sweep usually handles a damper problem.
Check the damper
The damper is opened and closed to see where it sticks or fails to seal. The smoke shelf and smoke chamber get a look as well.
Clear the frame
The damper frame and plate are cleaned so they can move freely. A cleaning is sometimes all it takes.
Fix the linkage
Broken handles, pins, springs or chains are repaired or replaced. Parts for some older dampers are no longer made.
Upgrade the damper
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.
Test the operation
The final step confirms the damper opens fully and closes tight. Ask how to work it if it is a new style.
What is included
Common damper repairs
Damper replacement
Failed dampers are replaced with a new throat damper or a top sealing damper matched to the flue.
Throat damper repair
Stuck, rusted or misaligned throat dampers are cleaned, adjusted and repaired with worn parts replaced.
Top sealing dampers
Top dampers close the chimney at the top, not the throat for a much tighter seal.
Damper stops
Fireplaces with vented gas logs need the damper fixed in an open position with a damper clamp which is a safety requirement.

Chimney Damper Replacement DuBois, PA
Some dampers are too far gone to repair, especially when the plate is rusted through or the frame is broken. Replacing a throat damper in place can be difficult, depending on how the fireplace was built. For many fireplaces, a top sealing damper is the easier and tighter fit.
When you call (814) 913-0171 from DuBois, 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. The sweep will explain the options and what fits your fireplace.

Top Sealing Damper DuBois, PA
A top sealing damper mounts at the top of the chimney and closes off the flue with a gasket that seals against the frame. It is opened and closed with a stainless cable that runs down the flue to a handle in the firebox. Some designs combine the damper with a cap and screen.
The flue stays closed off from outside air when the fireplace is not in use. It helps block rain and animals as well. Always make sure it is open before lighting a fire.

How the weather here affects chimneys around DuBois
Winters here are long and cold, and the heating season usually runs from October well into April. Masonry takes the worst of it from the freeze and thaw cycle: rain and melting snow soak into the crown and joints, then freeze and push them apart, which is how cracks, loose bricks and leaks start. Wind driven rain from coastal storms finds any gap in flashing, too. Most homeowners in DuBois, PA schedule a sweep in early fall, and a repair check after a hard winter.

Chimney Damper Repair questions
Is it safe to light a fire with a broken damper?
If the damper is stuck closed, lighting a fire will push smoke and carbon monoxide into the house. One that is stuck open is mostly an energy and comfort problem. Have it checked before using the fireplace again.
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. When not in use, a closed damper keeps drafts out.
Can I close the damper when using gas logs?
With vented gas logs, the damper has to stay open so carbon monoxide and other gases can go up the chimney. Closing the damper with gas logs running can fill the room with carbon monoxide. Working CO alarms are a must with any gas appliance.
What is a top sealing damper?
It is a damper at the top of the chimney that seals the flue when closed. You open and close it with a handle attached to a cable. Many models also act as a cap.
Why is my chimney damper stuck?
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. Cleaning or repair often frees it.
