Chimney Damper Repair Jenkintown, PA
A chimney sweep in Jenkintown can repair a damper that is stuck, rusted, warped or no longer seals so the fireplace drafts properly and stops leaking heated air. Call (267) 633-0240 to reach a local chimney sweep.
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. 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. Years of heat and moisture are hard on any damper.
If a damper will not open, lighting a fire sends smoke straight into the house. 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. Never close a damper on a fire or warm embers, since that pushes carbon monoxide into the home.
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.
If the problem goes deeper than it first looked, a Jenkintown chimney sweep may also recommend chimney cap installation or fireplace repair.

The damper repair process
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.
Clear the frame
Soot, creosote and rust are cleaned from the damper and frame. Many sticking dampers just need cleaning.
Repair the parts
The linkage between the handle and plate is fixed so it moves again. Some repairs depend on parts being available.
Upgrade the damper
When repair is not practical, a new damper goes in. The choice depends on the fireplace and the chimney.
Test the operation
The final step confirms the damper opens fully and closes tight. Ask how to work it if it is a new style.

Chimney Damper Replacement Jenkintown, PA
Replacement makes sense when a damper can no longer open, close or seal properly. A new throat damper is possible in some fireplaces, though the opening has to match. A top sealing damper often makes more sense than a new throat damper.
Calling (267) 633-0240 from Jenkintown 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. The sweep will explain the options and what fits your fireplace.

Top Sealing Damper Jenkintown, PA
Top sealing dampers sit on the top of the flue and close with a tight rubber or silicone gasket. A cable down the flue connects it to a handle mounted inside the fireplace. Some designs combine the damper with a cap and screen.
Because it closes at the top, it keeps cold air out of the whole flue, which can help the fireplace feel less drafty. It also keeps rain from running down the flue. Always make sure it is open before lighting a fire.

How the weather here affects chimneys around Jenkintown
Winters here are long and cold, and the heating season usually runs from October well into April. Masonry takes the worst of it from the freeze and thaw cycle: 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. That is why chimney cleaning in Jenkintown is usually booked in the fall, before the first cold night.

Chimney Damper Repair FAQ
What is a top sealing damper?
It is a damper at the top of the chimney that seals the flue when closed. You open and close it with a handle attached to a cable. It often replaces a failed throat damper.
Why is my chimney damper stuck?
Stuck dampers usually come from rust, heavy soot or a warped plate. Problems with the control mechanism are another common cause. The fix depends on what is causing the stick.
When should I close the fireplace damper?
The damper should stay open until there are no embers left, often many hours after the fire dies down. Closing it too early can push carbon monoxide into the home. Once the fireplace is cold, closing the damper keeps heated air from escaping.
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. A closed damper with logs burning is a serious carbon monoxide risk. 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?
If the damper is stuck closed, lighting a fire will push smoke and carbon monoxide into the house. If it is open, the fire will draft but heat escapes when it is not in use. Have it checked before using the fireplace again.
