Chimney Damper Repair Sewickley, PA
Damper problems in Sewickley fireplaces, from a broken handle to a rusted plate, can usually be fixed or replaced so the fireplace drafts properly and stops leaking heated air. One call to (412) 663-3115 reaches a nearby sweep who handles damper repair.
A chimney damper opens to let smoke out and closes to keep heated air from escaping up the chimney. Many fireplaces have a throat damper mounted above the firebox, while others have a top sealing damper at the top of the chimney. 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. If it happens with a fire going, open windows, get people out of the smoky room and call 911 if anyone feels sick or smoke keeps building. Leave the damper open until the fire and embers are completely out.
A damper that is stuck open or does not seal is less dangerous but costly in comfort. Throat dampers also tend to seal poorly over time as the plate warps or rusts. For many fireplaces, a top sealing damper is the better replacement.
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.
Check the damper
The technician checks how the damper moves and how well it closes. Soot and debris around it are cleaned away first.
Remove buildup
Buildup that keeps the plate from moving is removed. Many sticking dampers just need cleaning.
Fix the linkage
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. You will hear which choice makes sense for your fireplace.
Test the operation
The sweep tests the damper and checks the draft. You will be shown how to use it properly.
What is included
Common damper repairs
Handle repair
The connection between the control and the plate is repaired so you can open the flue easily.
New dampers
A new damper goes in when the old one is beyond repair matched to the flue.
Gas log damper clamps
A clamp or stop keeps the damper from fully closing where vented gas logs are used so gases can always escape.
Throat damper repair
The plate and frame above the firebox are freed and realigned with worn parts replaced.

Chimney Damper Replacement Sewickley, PA
Replacement makes sense when a damper can no longer open, close or seal properly. 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.
When you call (412) 663-3115 from Sewickley, mention whether the damper is stuck, rusted or just drafty. 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 Sewickley, PA
Mounted on top of the flue, a top sealing damper seals the chimney at the crown instead of at the throat. It is opened and closed with a stainless cable that runs down the flue to a handle in the firebox. Many models also act as a chimney cap, keeping out rain and animals.
Because it closes at the top, it keeps cold air out of the whole flue, which can help the fireplace feel less drafty. 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 Sewickley
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, 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 Sewickley is usually booked in the fall, before the first cold night.

Chimney Damper Repair questions
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. Embers still give off carbon monoxide, so closing early is risky. Once the fireplace is cold, closing the damper keeps heated air from escaping.
Why is my chimney damper stuck?
A damper sticks when rust, soot or debris keep the plate from moving. Worn linkage or a bent frame can cause it too. Cleaning or repair often frees it.
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. Get it repaired before the next fire.
How does a top sealing damper work?
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. Many models also act as a cap.
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. Closing the damper with gas logs running can fill the room with carbon monoxide. Working CO alarms are a must with any gas appliance.
