Chimney Damper Repair Natrona Heights, PA
A Natrona Heights chimney sweep can get a stuck damper working again so the fireplace drafts properly and stops leaking heated air. Dial (724) 604-6450 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. 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.
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. Leave the damper open until the fire and embers are completely out.
An open or leaky damper lets heated air escape and cold air come down the chimney. Warped or rusted plates rarely seal tightly, so drafts get through. That is why many homeowners replace a failed throat damper with a top sealing damper.
Many chimney damper repair calls in Natrona Heights also turn up a need for chimney cap installation or fireplace repair.

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. The smoke shelf and smoke chamber get a look as well.
Clean the area
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. A warped plate may not be fixable.
Upgrade the 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.
Final check
The damper is opened and closed several times to make sure it moves smoothly and seals. You will be shown how to use it properly.
What is included
Types of damper work
Top mount dampers
A top sealing damper closes the flue at the crown and is opened with a cable and often doubles as a cap.
Damper replacement
Rusted out or warped dampers are swapped for new ones matched to the flue.
Gas log damper clamps
Vented gas log fireplaces need a damper stop so gases can always escape.
Linkage repair
The connection between the control and the plate is repaired so you can open the flue easily.

Chimney Damper Replacement Natrona Heights, 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.
When you call (724) 604-6450 from Natrona Heights, 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. You will hear which replacement suits the fireplace.

Top Sealing Damper Natrona Heights, 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. 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 helps block rain and animals as well. Check that it is fully open before every fire.

Chimney Damper Repair Near Me
In Natrona Heights, an old throat damper that will not seal can let heated air escape all through the heating season.

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, and each winter widens the cracks a little more. Wind driven rain from coastal storms finds any gap in flashing, too. That is why chimney cleaning in Natrona Heights is usually booked in the fall, before the first cold night.

Chimney Damper Repair questions
Should the damper be open with gas logs?
With vented gas logs, the damper has to stay open so carbon monoxide and other gases can go up the chimney. Never close the damper while gas logs are burning. Working CO alarms are a must with any gas appliance.
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.
What is a top sealing damper?
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. Many models also act as a cap.
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. One that is stuck open is mostly an energy and comfort problem. Have it checked before using the fireplace again.
What causes a damper to stick?
A damper sticks when rust, soot or debris keep the plate from moving. Worn linkage or a bent frame can cause it too. The fix depends on what is causing the stick.
