Chimney Damper Repair Itasca, IL
A Itasca chimney sweep can get a stuck damper working again by freeing the plate, fixing the linkage or installing a new damper. Dial (331) 301-3229 to talk with a local chimney pro about your damper.
A chimney damper opens to let smoke out and closes to keep heated air from escaping up the chimney. In most masonry fireplaces it is a cast iron throat damper just above the firebox, worked by a handle, lever, rotary knob or poker. Because it sits in heat, soot and moisture, it wears out over time.
If a damper will not open, lighting a fire sends smoke straight into the house. 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. Never close a damper on a fire or warm embers, since that pushes carbon monoxide into the home.
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.
Depending on what the sweep finds, chimney damper repair in Itasca, IL can go hand in hand with chimney cap installation and fireplace repair.

The damper repair process
A damper repair starts with figuring out why it is not working.
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. This alone fixes some stuck dampers.
Free the plate
Broken handles, pins, springs or chains are repaired or replaced. A warped plate may not be fixable.
Upgrade the damper
If the throat damper has failed, a top sealing damper is a common replacement. 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
Broken handles, levers, rotary controls and pins are fixed so you can open the flue easily.
Gas log damper clamps

New dampers
Failed dampers are replaced with a new throat damper or a top sealing damper sized to the fireplace.
Cast iron damper repair
The plate and frame above the firebox are freed and realigned where the plate is still sound.

Chimney Damper Replacement Itasca, IL
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. Many homeowners choose a top sealing damper instead, since it mounts at the top and seals better.
If you are in Itasca, call (331) 301-3229 and describe what the damper does or does not do. Mention whether the fireplace burns wood or uses gas logs, since gas logs change the requirements. Ask about the pros and cons of each type.

Top Sealing Damper Itasca, IL
A top sealing damper mounts at the top of the chimney and closes off the flue with a gasket that seals against the frame. 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.
Because it closes at the top, it keeps cold air out of the whole flue, which can help the fireplace feel less drafty. It reduces water and debris getting in. Always make sure it is open before lighting a fire.

What the local climate does to a chimney
Winters here are cold and long, with lake effect snow in many towns and deep cold snaps that can last for days. Heating systems and wood stoves work nearly nonstop for months, so flues collect creosote fast and liners and crowns see a lot of heat and cold. Snow drifting against the back of a chimney melts slowly and works water under tired flashing. Most chimney cleaning in Itasca, IL happens right before the first snow.

Common questions about chimney damper repair
Why is my chimney damper stuck?
A damper sticks when rust, soot or debris keep the plate from moving. Problems with the control mechanism are another common cause. The fix depends on what is causing the stick.
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. Smoldering embers produce carbon monoxide that needs to vent. When not in use, a closed damper keeps drafts out.
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. You open and close it with a handle attached to a cable. Many models also act as a cap.
Can I use my fireplace if the damper is broken?
A damper that will not open makes the fireplace unsafe to use. 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.
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.
