Chimney Damper Repair Morrisville, PA
Damper problems in Morrisville fireplaces, from a broken handle to a rusted plate, can usually be fixed or replaced by freeing the plate, fixing the linkage or installing a new damper. Call (267) 697-3471 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. The most common type is a throat damper, a cast iron or steel plate that sits right above the firebox and opens with a handle or chain. Because it sits in heat, soot and moisture, it wears out over time.
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.
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.
Chimney Damper Repair is often paired with chimney cap installation and fireplace repair, depending on the cause.

How chimney damper repair works
Dampers fail for a few different reasons, so the fix depends on what is wrong.
Inspect the damper
The damper is opened and closed to see where it sticks or fails to seal. Rust and buildup are checked too.
Remove buildup
The damper frame and plate are cleaned so they can move freely. This alone fixes some stuck dampers.
Repair the parts
Broken handles, pins, springs or chains are repaired or replaced. A warped plate may not be fixable.
Install a new damper
When repair is not practical, a new damper goes in. You will hear which choice makes sense for your fireplace.
Test the operation
The sweep tests the damper and checks the draft. Ask how to work it if it is a new style.

Chimney Damper Replacement Morrisville, PA
When a damper is rusted through, cracked or badly warped, replacement is usually the only option. Throat dampers can be replaced with a new throat damper, but access is limited and fit can be tricky. For many fireplaces, a top sealing damper is the easier and tighter fit.
Calling (267) 697-3471 from Morrisville with a quick description of the problem helps the sweep plan. If the fireplace has gas logs, say so, since the damper must stay open with vented logs. You will hear which replacement suits the fireplace.

Top Sealing Damper Morrisville, PA
Top sealing dampers sit on the top of the flue and close with a tight rubber or silicone gasket. You work it with a handle in the firebox attached to a cable running up the chimney. Many include a built in cap and mesh.
Sealing the top stops cold air from filling the chimney, which keeps the fireplace area warmer. It also keeps rain from running down the flue. Check that it is fully open before every fire.

Chimneys in this climate
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. Most homeowners in Morrisville, PA schedule a sweep in early fall, and a repair check after a hard winter.

Chimney Damper Repair questions
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. Many include a cap and screen.
Why is my chimney damper stuck?
Stuck dampers usually come from rust, heavy soot or a warped plate. Worn linkage or a bent frame can cause it too. Cleaning or repair often frees it.
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. Get it repaired before the next fire.
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. Embers still give off carbon monoxide, so closing early is risky. When not in use, a closed damper keeps drafts out.
Should the damper be open with gas logs?
Gas logs that are vented require an open damper, typically secured with a clamp. Never close the damper while gas logs are burning. Keep CO alarms in the home and follow the manufacturer instructions for the logs.
