Wondering if your chimney damper needs to be replaced? There are various signs of damaged chimneys that should be replaced. The professional chimney experts are able to identify those signs and provide a replacement.
Some of the red flags of chimney dampers include smoke leakage, rusting, or damage. There will be unusual noises and higher energy bills. Most importantly, it will be difficult to operate. Over time, dampers can rust or stop sealing properly.
In this blog, we’ll walk you through everything you need to know about replacing a chimney damper, like the removal and installation process, cost expectations, and pros and cons of DIY and calling professionals.
What is a Chimney Damper?
A chimney damper is an important component of a fireplace that helps regulate the airflow and prevent heat loss when the fireplace is not in use. It is placed above the firebox in the throat of the chimney. You can open and close it according to how much smoke you want.
When a chimney damper is open, it helps smoke and gases escape out of the chimney. It balances the airflow as well. On the other hand, when it’s closed, it prevents the cold air from getting into the house and keeps the house warmer inside.
Types of Chimney Dampers
There are two main types of chimney dampers. They are located at different positions in a chimney.
Throat Dampers
Throat dampers are the traditional dampers that are located above the firebox. They are placed near the base of the chimney. These are the most common forms of dampers.
Top-sealing Dampers
These are placed at the top of the chimney. They are said to be modern. They are more likely to be energy-efficient. They provide a much tighter seal than the traditional dampers.
When to Replace a Chimney Damper?
- The damper doesn’t open or close properly anymore.
- You feel drafts even when it’s closed.
- There’s visible rust or corrosion on the damper.
- Smoke sometimes comes back into the room when you use the fireplace.
- You hear rattling or notice it feels loose when operating it.
- The damper handle or chain is broken or hard to move.
- You notice higher energy bills due to air leaks through the chimney.
- There’s visible warping, cracks, or gaps around the damper plate.
The Professional Replacement Process For Chimney Dampers
1. Preparation
Make sure that the chimney is cool and the fireplace is clean. The professionals gather the ladder, gloves, wrench and of course a new damper. They inspect the defects in your existing damper and take measurements.
2. Removing the old Chimney Damper
Professionals use a flashlight to locate the metal plate. They observe how it is attached and then remove the damper control rod. They detach it very carefully and scrap off any kind of rust or mortar. They clean it up and brush it before installing a new chimney damper.
3. Installing a New Chimney Damper
To install a new chimney damper, the expert need to fit and secure the new unit. They test and seal the movement of the damper and properly seal the joints to prevent air leaks.
4. Post-Installation Checks
After installing the damper, experts test the airflow and drafts. They carefully verify the smoke venting and proper closure. They also inspect if the damper is installed according to the design specifications, and ensure that it is properly seated and aligned within the flue. At the end, they confirm compliance with fire safety regulations.
Cost of Replacing a Chimney Damper
A chimney damper cost depends on the circumstances, the sizes, the customisations, etc. If you do it yourself, it will probably cost you around $100 to $250, but it might be risky for a non-professional to replace a chimney damper. Commonly, the cost of replacing a Chimney Damper professionally for typical jobs falls around $500. It varies according to specific damper replacements. You’d reasonably expect a chimney damper cost of $300 to $500+, especially in cities like Massachusetts.

Maintenance Tips for Longer Damper Life
It’s so important to keep a track of maintenance to ensure a longer damper lifespan. Get it inspected by professionals; they can spot issues like rusting and air leakage long before you notice. There should be regular cleaning inspections because the ashes and tar substances can cause the damper to jam. Make sure to remove the rust with sandpaper if you see any.
Open the damper fully before you use it so that the carbon monoxide and smoke escape the home easily. Carefully close it when it’s not in use, so the dust from the outside won’t get in. It keeps the cold outside and maintains the temperature. Before the heating season begins, test the damper to ensure it opens and closes properly without any friction.
DIY vs Professional Replacement
There are pros and cons of replacing the chimney damper yourself, and the only pro is that it will be less costly as compared to a professional replacement. But the cons are too many! Mainly, there are safety risks, incorrect sizing, limited tools and equipment, and there is no warranty or professional guarantee. Calling a chimney technician is always a smarter choice.
Professionals provide safety assurance, long-term durability, and warranty protection. Hiring a professional chimney expert ensures that your chimney damper is installed perfectly and efficiently. You’ll save time and mental peace.
