The average chimney damper replacement costs $360, with prices varying between $120 and $700 depending on the damper type and the damage involved. Dampers open and close to allow airflow when a fire is burning and prevent heat loss when the fireplace isn't in use. Experienced homeowners might save with DIY replacement, but most should hire a pro for safety.
Chimney Damper Replacement Cost Factors
The cost to replace a chimney damper will vary depending on a number of factors, including damper type and size, labor cost, repair type, and permit fees.
Damper Type
There are several different types of dampers, and the price you pay for materials will vary depending on which type you need.
| Damper Type | Average Cost |
|---|---|
| Chimney cap damper | $125–$225 |
| Cast-iron throat damper | $150–$250 |
| Top-mount damper | $250–$500 |
Damper Size
Chimneys vary in size, so damper sizes vary accordingly. Expect material costs to increase slightly as the damper size increases.
| Chimney Flue Size in Square Inches | Average Damper Cost |
|---|---|
| 64–117 | $270 |
| 128–153 | $290 |
| 144–169 | $300 |
| 221 and up | $330 |
Labor
If you hire a chimney technician to replace your fireplace damper, expect to pay $200 to $400 for professional labor on top of the material cost of a new damper. Costs may vary based on the availability of qualified professionals in your area.
Repair vs. Replacement
Chimney damper damage can vary in severity. When you're experiencing problems, get a thorough professional chimney inspection to diagnose the issue. Repair of your existing damper may cost just $100 to $225 compared to full replacement, which costs $160 to $520 on average.
Permits
A permit typically isn’t needed for damper repair or replacement. However, a larger chimney repair job that involves masonry work may require a permit depending on the regulations in your local area. Talk to your chimney technician or call your local building department to learn more. If a permit is needed, expect to pay $100 to $400 for the permit and any inspection fees.
Why You Should Hire a Chimney Damper Pro
When you hire a chimney repair specialist near you to replace your damper, labor accounts for roughly half the project cost. Despite this, damper installation and other chimney projects are always best left to the pros to ensure safety and efficiency while preventing costly mistakes related to improper sealing or damage to the structure of the chimney itself.
Here’s why it’s ideal to hire a chimney damper pro
Chimney dampers serve a critical role and should be installed by a pro for the following reasons:
Chimney professionals have the experience to ensure the damper is installed accurately.
They can prevent uncomfortable drafts and higher energy bills due to improper sealing.
Pros minimize health and safety risks such as carbon monoxide buildup and fire danger.
Chimney components are delicate, and DIY mistakes can cause structural damage.
A professionally installed damper will last many years without needing replacement.
Hiring a pro is more cost-effective than an improper installation that requires repairs.
A pro near you will have experience with local codes and ensure legal compliance.
Safety Warning
Leave all chimney work to a pro. Chimney jobs involve working on a roof, potential exposure to creosote, and ensuring a safe repair or installation of chimney parts. Each of these can be seriously harmful or even deadly for anyone without expertise.
A local chimney repair company is best equipped to safely and thoroughly inspect, clean, and replace your damper.
Cost of Common Chimney Add-Ons
When you have your chimney damper inspected for potential replacement, your chimney technician may notice other problems that you can handle all at once. You may also wish to have other work done on your chimney.
Chimney cap installation cost: $75–$500
Chimney cleaning cost: $130–$380
New chimney liner cost: $1,500–$5,000
Angi Tip
Creosote is a flammable residue that builds up due to incomplete combustion and can cause chimney fires if not cleaned regularly. Hire a chimney sweep to remove creosote build up at least once per year—or more frequently if you use your fireplace often.
How You Can Save Money While Dealing With a Faulty Chimney Damper
Saving money on damper replacement itself isn’t always possible, but there are ways to keep your chimney and its parts in good condition to reduce the likelihood that you’ll need damper replacement in the future:
Hire a chimney sweep to clean your damper and chimney first. Chimney cleaning costs of $130 to $380.
Stay on top of annual inspections for your chimney.
Always open the damper before starting a fire.
Don’t forget to close your damper after the fire is completely out.
Next Steps: Finalize Your Project With a Pro
Verify the pro’s certifications with reputable industry organizations such as the Chimney Safety Institute of America (CSIA).
Ask for references and read reviews before hiring a chimney specialist.
Be prepared to ask about other services the pro provides, such as routine maintenance and inspections of the damper and other chimney components.
