Chimney cleaning is tough task. While it is important that you keep it well-maintained, on the other hand it is surely a daunting task and you should consider hiring chimney contractors for it. However, there is no need to panic. In this blog, we are going to discuss how you can clean your chimney from the bottom.


Before you begin cleaning the chimney from the bottom, you should prepare all the tools and equipment needed. It is recommended that you cover the floor with clothes so that you can collect and throw away the soot later. You should know that cleaning the chimney is a very messy process. You should cover your eyes and other exposed body parts to prevent any harm.

Choosing A Chimney Brush

When it comes to cleaning the chimney, there are a variety of brushes out there to choose from. Depending on the size, type and location of the fireplace, you are going to need a chimney brush that allows easy access. To have the right size of the brush, you should first measure the chimney size from the inside. This will prevent you from buying a brush that is either too short or long for the purpose.

How to measure the chimney for selecting a brush? You should take out the chimney cap to measure the distance across the inner diameter of the round chimney flue.

For chimneys with metal lining, selecting a poly bristled brush is better because it will clean the inner wall of the chimney without having to be grooved. In case of a masonry chimney brush, measure the inner flue liner dimensions from both directions. As a result, you are going to choose a brush that matches the readings.

Oval flues are not common, but if you have a chimney with an oval flue, you are going to measure it the same way as the masonry chimney. And yet again, choose a chimney brush that is as close to the readings as possible. We recommend using wire brushes for masonry flues or porous clay to efficiently clean and clear the creosote build-up. If you are not able to find the appropriate brush, you should opt for the one that is larger but close to the flue size. Then, you will need to trim the bristles down so that it matches the flue opening. And the same goes for an oval flue as well. The key is that the brush needs to reach the walls properly in order to clean them.

Choosing The Rods

Now that you have selected the right size, it is time to shift your attention to the rod types. There are three types of rods, nylon, fiberglass and polypropylene. Fiberglass happens to be the stiffest amongst them. Such rods are recommended to be used in flues that are straight. They are perfect for straight flues with tough creosote buildup to push through.

Nylon rods tend to be flexible and are used for chimneys that feature tight bends. These rods are capable of bending 90 degrees but can be too flexible for long chimney runs. Finally, polypropylene rods are flexible enough to go through breaches, offsets and sharp bends etc.

Cleaning The Chimney Using The Bottom Up Brush And Rod Method

With everything in place, it is time that you get started with the chimney cleaning. If you plan on going with the popular bottom up brush and rod method, you need to be on the ground rather than on the roof. Make sure that you are wearing protective gear and cover the eyes and other sensitive parts. Cleaning soot buildup is not easy at all and you will need to show some patience and put in hard work.

Simply, grab the chimney brush, hold it firmly and insert it inside the chimney. Use the push and pull motion to clean creosote buildup. Afterwards, remove the cloth that contains the buildup and vacuum the floor.
