Chimney Damper Repair Delmont, PA
A Delmont chimney sweep can get a stuck damper working again so the fireplace drafts properly and stops leaking heated air. Call (724) 412-9258 to reach a local chimney sweep.
A chimney damper opens to let smoke out and closes to keep heated air from escaping up the chimney. 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 stuck shut damper means smoke and gases spill into the room instead of rising up the flue. 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. A damper should stay open until the ashes are cold.
A damper that will not close lets warm air out all winter and cooled air out all summer. Throat dampers also tend to seal poorly over time as the plate warps or rusts. For many fireplaces, a top sealing damper is the better replacement.
Depending on what the sweep finds, chimney damper repair in Delmont, PA can go hand in hand with chimney cap installation and fireplace repair.

How chimney damper repair works
A damper repair starts with figuring out why it is not working.
Inspect the damper
The damper is opened and closed to see where it sticks or fails to seal. Soot and debris around it are cleaned away first.
Clean the area
The damper frame and plate are cleaned so they can move freely. A cleaning is sometimes all it takes.
Repair the parts
Broken handles, pins, springs or chains are repaired or replaced. Parts for some older dampers are no longer made.
Replace if needed
If the throat damper has failed, a top sealing damper is a common replacement. The sweep explains the options before any replacement.
Check the seal
The sweep tests the damper and checks the draft. You will be shown how to use it properly.
What is included
Types of damper work

Handle repair
The connection between the control and the plate is repaired so you can open the flue easily.
New dampers

Chimney Damper Replacement Delmont, PA
Replacement makes sense when a damper can no longer open, close or seal properly. Replacing a throat damper in place can be difficult, depending on how the fireplace was built. Many homeowners choose a top sealing damper instead, since it mounts at the top and seals better.
If you are in Delmont, call (724) 412-9258 and describe what the damper does or does not do. If the fireplace has gas logs, say so, since the damper must stay open with vented logs. The sweep will explain the options and what fits your fireplace.

Top Sealing Damper Delmont, 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.
The flue stays closed off from outside air when the fireplace is not in use. It reduces water and debris getting in. Always make sure it is open before lighting a fire.

How the weather here affects chimneys around Delmont
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, which is how cracks, loose bricks and leaks start. Wind driven rain from coastal storms finds any gap in flashing, too. Most homeowners in Delmont, PA schedule a sweep in early fall, and a repair check after a hard winter.

Chimney Damper Repair questions
What causes a damper to stick?
Stuck dampers usually come from rust, heavy soot or a warped plate. Worn linkage or a bent frame can cause it too. A sweep can clean it, repair the parts or replace the damper.
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. It is operated by a cable that runs down to a handle in the firebox. It often replaces a failed throat damper.
How long should I wait to close the damper after a fire?
Leave the damper open until the ashes are cold, which can take many hours. Smoldering embers produce carbon monoxide that needs to vent. Closing it when the fireplace is not in use saves energy.
Should the damper be open with gas logs?
Vented gas logs need the damper fixed open, usually with a damper clamp, because they produce combustion gases that must escape. Never close the damper while gas logs are burning. Keep CO alarms in the home and follow the manufacturer instructions for the logs.
Is it safe to light a fire with a broken damper?
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. Have it checked before using the fireplace again.
