Regular Maintenance

There are certain maintenance procedures you should do each year to keep your chimney free from debris, clogs, and fire hazards. Make sure to inspect the surface of the chimney and the surrounding areas for any type of damage, deterioration or cracks. If you notice any, you will have to get them repaired as soon as possible to prevent any accidents. Check for any loose bricks, as they can drop off at any time and cause serious injury to you or someone else. If there are any loose bricks, use mortar to secure them back in place. When inspecting your chimney from the inside, make sure to wear protective gear, such as gloves and a mask.

Sweeping the Chimney

If you are cleaning your chimney manually (not using a robot), you should start by sweeping the chimney. It is recommended that you use a natural fiber brush to prevent any damage to the bricks. Before you begin sweeping, make sure the fireplace is turned off and there are no open flames nearby. With the fireplace turned off, you can use a shop vac to collect the soot and ash. Make sure to remove the ash and soot from the inside and the outside of the chimney. You can wrap a rag around the shop vac hose to catch the debris, and then you can use the vacuum to suck it all up. When you are done, make sure to clean the vacuum filter as well to prevent any ash from being released back into the air.

Using A Chimney Cleaning Robot

If you want to clean your chimney without lifting a finger, using a robot is the way to go. These devices are easier and safer to use than standard sweeping methods, and they are recommended for those who aren’t very physically active. When using a robot, you should follow the user guide provided with the device. There are different devices with various specifications and features, so make sure to read about them carefully before choosing one for your home. Chimney cleaning robots use a combination of rotating brushes and high-pressure water jets to remove debris and soot buildup from your chimney. To operate them, you should connect them to a standard garden hose, and they will suck up the ash and soot. Make sure to clean the inside of the chimney thoroughly, including the flue.

Hiring A Professional Chimney Sweeper

If you don’t have the time, resources, or access to the necessary equipment to clean your chimney manually, you can always hire a professional chimney sweeper. Make sure to research your options to find a reputable company with positive reviews and experience in cleaning chimneys. If you hire a company, always ask about their cleaning process and whether they use chemicals to clean the chimney. Before you hire a professional, make sure to inform them about any obstacles they might encounter while cleaning the chimney. This can help them avoid any dangerous situations and reduce the risk of injury.

Most Important Tips To Keep Your Chimney Clean

  • If your chimney is not cleaned annually, soot and ash will start to build up inside it, which will lead to reduced efficiency, clogged flues, and a risk of fire. When this happens, cleaning the chimney will be a lot more difficult and dangerous.
  • When you clean the inside of your chimney, make sure you don’t use any type of burning device to start the fire. This can cause a backdraft or suction from the chimney that could lead to serious injury.
  • If you have an electric fireplace, you can use that to generate heat and create a cozy atmosphere. Just make sure that you don’t plug it into the same outlet you use for your TV or other electronic devices.
  • If you have a wood burning fireplace, you’ll need to use real wood as fuel. Make sure to use wood that isn’t too green or moist, as this can create excessive smoke.


Keeping your chimney clean is essential for safety and efficient operation. Use these tips and tricks to clean your chimney properly, and you’ll be able to enjoy the beauty, warmth, and ambiance of a crackling fire for years to come. With the fireplace operational, you’ll be able to save on your heating bill and enjoy a cozy retreat during cold weather.
