It’s important to understand the processes that your chimney goes through and the repairs that may need to be undertaken. Unfortunately, sometimes even the terms can be confusing. You hear about dampers and the smoke box and the chimney crown and the chase and the chase cover…but do you really know what all these terms mean? Another term that’s really important to understand is tuckpointing.

What Damage Might Be OccurringThe Process and Importance of Tuckpointing Image - Chicago IL - Jiminy Chimney Masonry & Repair

There are many things that may cause damage to your chimney system. Weather, and especially precipitation, is one of those things. When rains hit, it can wear away at the mortar between the bricks or blocks of your chimney. And if it’s winter, when precipitation gets into the pores of the bricks or the mortar and freezes, it’ll expand and make those cracks even bigger. The Chimney Safety Institute of America states that masonry products can deteriorate very rapidly during the freeze/thaw cycle.


When you’re discussing tuckpointing, the first thing you need to know is what the mortar joints are. Mortar joints are just the spaces between the bricks of your chimney, and those spaces are filled with mortar. When the mortar starts to breakdown, it becomes even more absorbent, and that can cause major structural damage. That breakdown actually begins with the wear and tear from precipitation. The fix to this is called tuckpointing or repointing.

Tuckpointing is the process of removing old, deteriorating mortar joints and replacing them with fresh mortar. Although that seems like it would be a pretty simple process, there are several things to take into consideration when thinking about undertaking the process. It’s important to make sure that the new mortar matches the old mortar and that the mortar is properly tucked back into place. It’s also important to know how old your chimney is and the type of mortar that was used originally. With all these things to think about, it’s pretty clear pretty quickly that this is a job best left to the professionals.

Necessary Repair

Tuckpointing is more than just cosmetic repairs. Although it is important that your chimney looks great, it’s even more important structurally. Mortar and moisture don’t really mix, and if left untreated, that deterioration will only get worse. Not only can your chimney structure be damaged, but other elements of your chimney system can also be affected, including the damper, the flue liner, or even the firebox. When precipitation is allowed to enter into your chimney system, these elements can become rusted and damaged.
