How Much Does It Cost To Clean a Chimney?

From the crackling of the logs to the warm glow of the fire, sitting in front of a fireplace is a calming and relaxing way to spend an evening. While you probably clean up the firebox, it’s easy to overlook your chimney. Over time, soot and creosote can build up inside and even pose a fire risk. Not only does chimney cleaning ensure the safety of your home and family, but it also prolongs the life of your chimney and improves the efficiency of your fireplace. In this article, we will discuss the cost of cleaning a chimney as well as what is actually involved. Plus, we answer some of the most frequently asked questions about chimney cleaning.

How Much Does Chimney Cleaning Cost?

The national average cost of chimney cleaning is about $250, but the actual price varies depending on a number of factors Generally, you can expect an average cost ranging from $120 to $400 for chimney cleaning across the country.

While chimney cleaning is the most commonly used term, chimney sweeping and flue cleaning are also used. Historically the three terms were different, but they are used interchangeably today.

Factors that determine the cost of cleaning a chimney include the size of the chimney, the type of fuel used, the condition of the chimney, and the location of the chimney. Additionally, the cost of chimney cleaning may be higher for chimneys that are located in hard-to-reach areas or that require specialized equipment.

While this may seem like an unnecessary cost, regular maintenance, cleaning, and chimney inspections are important to keep you safe. Without regular cleaning, you risk the potential of chimney fires or even damaging your flue liner or chimney liner. Although rare, an excessive buildup of creosote can weaken older chimneys or lead to structural damage.

An annual inspection and cleaning is recommended for any chimney. This is not just limited to wood-burning fireplaces, but also includes oil or gas fireplaces, wood stoves, and pellet stoves.

Factors That Determine the Cost of Chimney Cleaning

Several factors determine the cost of cleaning a chimney:

1. Size of the chimney: The larger the chimney, the more time and effort it takes to clean, which can increase the cost.
2. Type of fuel used: The type of fuel used in your fireplace (such as wood, gas, or oil) can affect the amount of creosote and other buildup in your chimney, which can affect the cost of cleaning.
3. How often the chimney is used: Another factor in chimney cleaning costs is how often you use your chimney. Cleaning is usually less if you only have one or two fires a season than if you use your fireplace frequently.
4. Time since the last cleaning: The time since your last chimney cleaning will also impact the cost. Expect the cleaning to cost more if it’s been several years since your last service than if you have your chimney serviced regularly
5. Condition of the chimney: The condition of your chimney can affect the cost of cleaning. If your chimney is in good condition, it will likely cost less to clean than if it is in poor condition and needs repairs.
6. Location of the chimney: The location of your chimney can also affect the cost of cleaning. If your chimney is located in a hard-to-reach area, or if it requires specialized equipment to access, the cost of cleaning may be higher.
7. If repairs are necessary: If the sweep finds damage during the cleaning, repairs will increase the overall cost.

What Is Included in Chimney Cleaning?

In most cases, the chimney sweep will perform the following services during a cleaning:

1. Inspection: The sweep will first inspect your chimney to check for any damage or potential hazards. They will also determine the type of fuel used in the fireplace and the condition of the chimney.
2. Set-up: The sweep will set up equipment, such as tarps and vacuums, to protect your home and contain any debris during the cleaning process.
3. Removal of debris: Next, they will remove blockages, buildup, and soot using a special set of tools and brushes. They clean the chimney cap, throat, and liner, as well as the smoke chamber, smoke shelf, damper, and firebox.
4. Creosote treatment: For severe creosote buildups, they will apply a chemical treatment. This helps loosen the creosote, making it easier to clean and remove.
5. Vacuuming: Once all the debris is loosened, the sweep will use a HEPA vacuum to suck up any soot, creosote, or other debris.
6. Final inspection: The sweep will conduct a final inspection of the chimney to ensure that it is clean and safe to use.
7. Clean up: The sweep will remove all the equipment and debris from your home, leaving you with a clean chimney and fireplace.

It is important to note that depending on the condition of the chimney and the type of fuel used, additional steps may be required.

Do Chimney Sweeping or Cleaning Logs Really Work?

Chimney sweeping logs and chimney cleaning logs are marketed as an easy and convenient alternative to professional chimney cleaning. They claim to remove creosote and other buildups from the chimney by burning the logs in your fireplace.

However,  these products are not a substitute for annual cleanings by chimney professionals. The Chimney Safety Institute of America (CSIA) states that these logs are not effective in removing hard, compacted creosote, which can build up in the chimney and create a fire hazard. Additionally, the National Fire Protection Association (NFPA) states that creosote removers should not be used as a substitute for professional cleaning.

It is always recommended to have a professional chimney sweep inspect and clean your chimney. They have specialized equipment and the knowledge to safely clean your chimney. And, if you burn wood, you should have your chimney cleaned at least once a year. If you burn oil or gas, you may need to have your chimney cleaned less frequently.
