A properly functioning fireplace damper is one of the most over looked but essential components of your fireplace system. It controls air flow, prevents heat loss, and protects your home from smoke and outside elements. Whether you need a damper repair, replacement, or upgrade, 1 Hour Chimney provides fast, professional solutions that ensure your fireplace operates safely and efficiently.
If your damper is stuck, rusted, missing, or letting cold air in—don’t wait. We’ll help restore comfort, safety, and control with expert service you can trust.

















A fireplace damper is a movable plate located within the chimney that opens and closes to control the flow of air and smoke. It’s typically located just above the firebox (throat damper) or at the top of the flue (top-sealing damper).
Here’s why it matters:
Whether you’re replacing a broken damper or upgrading to a more efficient model, we offer full-service damper solutions for all fireplace types.
We fix rusted, bent, or misaligned dampers that don’t seal properly. Our technicians lubricate moving parts, replace broken handles, and realign the mechanism to restore full functionality.
If your existing damper is too damaged to repair, we’ll replace it with a modern, high-efficiency option.We offer both traditional and top-sealing dampers based on your chimney’s setup and your goals.
Also called “energy-saving”or “seal-tight” dampers, these install at the chimney cap and act as both a damper and weather seal. They're great for reducing heating loss and preventing animals, moisture, or odors from entering your home.
At 1 Hour Chimney, we only install industry-trusted dampers built fordurability and long-term performance.

Every job we do is designed to be fast, clean, and thorough. Here's how our damper service works:
We start with a visual inspection of your damper and fireplace system. We check for rust, warping, corrosion, or obstructions and determine whether a repair or replacement is needed.
Based on your chimney type and fireplace usage, we recommend the most appropriate damper solution, traditional or top-sealing—with clear, upfront pricing.
Our technicians make sure the damper is securely installed or repaired using manufacturer-approved methods. We test the mechanism to ensure smooth opening and closing.
We confirm proper operation with a draft test, ensure an airtight seal when closed, and provide usage tips for extending your damper’s life.


Not sure if your damper is working properly? These common signs may indicate it’s time for a repair or replacement:
Keep it closed when not in use to prevent drafts and energy loss. Always open it before lighting a fire.
You can usually see up into the flue with a flashlight. If it’s open, you'll see into the chimney; if closed, a metal plate will be in place.
Yes. We can replace just the damper and ensure it fits your existing fireplace structure perfectly.
Top-sealing dampers provide better energy savings and pest protection. We’ll help you decide based on your chimney and budget.
Most replacements are completed in under two hours, depending on chimney access and damper type.
Yes. A properly sealed damper helps block odors, rain, pests, and debris from entering your chimney.
We recommend checking and operating your damper a few times a year. Light lubrication and annual inspection help prolong its life.
