How to clean the chimney: which technique should I use?

If this is the first time you are faced with this question, you should start by checking if what your chimney is asking for is a maintenance cleaning or a complete cleaning.

At the end of the winter season, it should be deep cleaned at least once a year. As for maintenance cleaning, it should be done once a week during the winter.

What types of chimney sweeping are there?

There are two options when it comes to cleaning a chimney:

  • Mechanical chimney sweeping: cleaning is done with a special brush called a hedgehog brush. These brushes incorporate a flexible guide to be able to reach all the points of the chimney.

    Thanks for pointing out that chimney sleeping should be done every year after the end of the winter season and its maintenance should also be done every week during the winter. It is the first time that we are living in a house with a chimney after moving into this property that my husband bought this year. Since we are new to having this kind of feature in our house, it is better if we let the professionals handle its maintenance and get it checked by them every now and then for our own safety when we start using it after the summer season.

    Thanks for helping me understand that the chimney has to be cleaned after the winter season or at least once a year while maintenance cleaning would be needed once a week during that season. I probably need to hire chimney cleaning services before summer ends in order to prepare the fireplace for the fall season. Is because I easily get cold, especially when this new place I moved into is way colder compared to the state I came from and lived in for almost years.
