Even though brick and stone chimneys are built to last, they have a major enemy: water. This seemingly simple element, H2O, is actually one of the most damaging forces a chimney can encounter. The problem is that bricks and mortar are porous, so they soak up water like a sponge. Over time, this constant moisture exposure can wear down the chimney much faster than normal. This can lead to issues like brick spalling, where pieces of the brick start to break off, and in severe cases, it can even cause the chimney to collapse.
Therefore, waterproofing your chimney is a straightforward and effective measure that can significantly prolong its lifespan and help prevent costly repairs. The waterproofing membrane layer enables the chimney to "breathe," preventing the buildup of water molecules that can speed up the deterioration of the masonry.
How to know if your chimney is leaking?
Here are some signs that your chimney may need leak repair:
Water stains on the walls or ceilings near the chimney.
Efflorescence: white, chalky deposits on the exterior of the chimney.
Deteriorating mortar between the bricks or stones.
Rust on the metal components of your chimney, such as the damper or flashing.
A musty odor, mold or mildew around the fireplace or chimney area.
A cracked chimney crown.
Pooling water around the base of the chimney or on the roof.
Chimney waterproofing is a preventive action, but it should only be done after any existing damage, like cracks, gaps, voids, or missing mortar, has been repaired. Additionally, the chimney's exterior may need to be cleaned before the waterproofing material is applied.
