Chimney Damper Repair Bryn Mawr, PA

A chimney sweep in Bryn Mawr 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. One call to (484) 380-7228 reaches a nearby sweep who handles damper repair.

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. 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. Never close a damper on a fire or warm embers, since that pushes carbon monoxide into the home.

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. That is why many homeowners replace a failed throat damper with a top sealing damper.

Many chimney damper repair calls in Bryn Mawr also turn up a need for chimney cap installation or fireplace repair.

The process

The damper repair process

Dampers fail for a few different reasons, so the fix depends on what is wrong.

  1. Inspect 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.

  2. Clear the frame

    The damper frame and plate are cleaned so they can move freely. This alone fixes some stuck dampers.

  3. Repair the parts

    Worn parts are swapped and the plate is adjusted to close properly. Some repairs depend on parts being available.

  4. Upgrade the damper

    When repair is not practical, a new damper goes in. The choice depends on the fireplace and the chimney.

  5. Check the seal

    The sweep tests the damper and checks the draft. Ask how to work it if it is a new style.

What is included

Common damper repairs

Handle repair

The connection between the control and the plate is repaired for smooth operation.

Gas log damper clamps

Vented gas log fireplaces need a damper stop which is a safety requirement.

Top sealing dampers

Top dampers close the chimney at the top, not the throat for a much tighter seal.

New dampers

Rusted out or warped dampers are swapped for new ones with the right control for your fireplace.

Throat damper repair

Throat dampers that stick or leak are repaired so they open and close again.

Chimney Damper Replacement Bryn Mawr, PA

Some dampers are too far gone to repair, especially when the plate is rusted through or the frame is broken. A new throat damper is possible in some fireplaces, though the opening has to match. For many fireplaces, a top sealing damper is the easier and tighter fit.

If you are in Bryn Mawr, call (484) 380-7228 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. The sweep will explain the options and what fits your fireplace.

Top Sealing Damper Bryn Mawr, 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 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 helps block rain and animals as well. In very cold weather, the gasket should be checked to make sure it has not frozen to the frame before a fire is lit.

How the weather here affects chimneys around Bryn Mawr

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: 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 Bryn Mawr, 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. 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.
Should the damper be open with gas logs?
Gas logs that are vented require an open damper, typically secured with a clamp. Closing the damper with gas logs running can fill the room with carbon monoxide. If you smell gas, leave the house without touching switches and call the gas utility or 911 from outside.
What causes a damper to stick?
A damper sticks when rust, soot or debris keep the plate from moving. A broken handle, a slipped chain or a warped plate can also keep it from moving. Cleaning or repair often frees it.
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.
What is a top sealing damper?
Top sealing dampers sit on top of the flue and seal it with a rubber or silicone gasket. It is operated by a cable that runs down to a handle in the firebox. It often replaces a failed throat damper.
