Chimney Damper Repair Swedesboro, NJ
A chimney sweep in Swedesboro can repair a damper that is stuck, rusted, warped or no longer seals by freeing the plate, fixing the linkage or installing a new damper. Dial (856) 490-5006 to talk with a local chimney pro about your damper.
Your damper is the plate or door that controls whether the flue is open or closed. 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. 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. A top sealing damper often solves both the seal and the rust problem.
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.
Inspect the damper
The sweep looks at the plate, the frame, the handle and the linkage. Rust and buildup are checked too.
Clean the area
Buildup that keeps the plate from moving is removed. This alone fixes some stuck dampers.
Free the plate
The linkage between the handle and plate is fixed so it moves again. Parts for some older dampers are no longer made.
Upgrade the damper
If the throat damper has failed, a top sealing damper is a common replacement. The choice depends on the fireplace and the chimney.
Final check
The damper is opened and closed several times to make sure it moves smoothly and seals. Ask how to work it if it is a new style.

Chimney Damper Replacement Swedesboro, NJ
Some dampers are too far gone to repair, especially when the plate is rusted through or the frame is broken. Throat dampers can be replaced with a new throat damper, but access is limited and fit can be tricky. A top sealing damper often makes more sense than a new throat damper.
If you are in Swedesboro, call (856) 490-5006 and describe what the damper does or does not do. Gas logs and wood fires need different damper setups, so tell the sweep which one you have. Ask about the pros and cons of each type.

Top Sealing Damper Swedesboro, NJ
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 models also act as a chimney cap, keeping out rain and animals.
Sealing the top stops cold air from filling the chimney, which keeps the fireplace area warmer. It reduces water and debris getting in. In very cold weather, the gasket should be checked to make sure it has not frozen to the frame before a fire is lit.

Chimneys in this climate
Cold winters keep fireplaces, wood stoves and oil burners working for half the year or more. Masonry takes the worst of it from the freeze and thaw cycle: 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. Nor'easters drive rain sideways into flashing and mortar that looked fine in summer. That is why chimney cleaning in Swedesboro is usually booked in the fall, before the first cold night.

Chimney Damper Repair questions
When should I close the fireplace damper?
Leave the damper open until the ashes are cold, which can take many hours. Closing it too early can push carbon monoxide into the home. Once the fireplace is cold, closing the damper keeps heated air from escaping.
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. 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.
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. Never close the damper while gas logs are burning. Keep CO alarms in the home and follow the manufacturer instructions for the logs.
What causes a damper to stick?
Rust, soot and creosote buildup are the most common reasons a damper sticks. Problems with the control mechanism are another common cause. A sweep can clean it, repair the parts or replace the damper.
How does a top sealing damper work?
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 include a cap and screen.
