The condition of the masonry surrounding your chimney can have an impact on its functionality and life span, so it’s important to be aware of its causes. Batts’ Chimney Services takes a look at the common reasons why chimney masonry can crumble and what solutions are available to keep yours in good shape.
Causes of Crumbling Chimney Masonry
Chimney masonry is essentially the part that’s made of bricks and mortar, and a significant portion of it is exposed to wear from the elements. Most of the problem is rooted in the fact that bricks are vulnerable to moisture damage. Brick may also start popping and flaking — also known as “spalling” — from the moisture in the brick expanding and contracting due to temperature changes. Poor construction practices and use of low-quality materials may also contribute to crumbling masonry.
Solutions for Crumbling Chimneys
If you’re seeing signs of crumbling chimney masonry, call your local chimney professional. Depending on the extent of the damage, they may do one or more of the following:
- Repointing is a process that involves removing old mortar between the bricks and reapplying new mortar. This is done when the bricks are still in good shape. Tuckpointing is a similar process where the new mortar is colored to match the bricks, creating a homogeneous look.
- Rebuilding involves taking apart the existing masonry and rebuilding it with new blocks and mortar. This is done when both brick and mortar are damaged.
- Leak repair can save existing masonry from further damage by fixing moisture infiltration points. Repairs usually involve sealing cracks or gaps in the mortar joints with a waterproof sealant.
- Regular maintenance remains the best way to keep the chimney masonry from crumbling. Part of professional chimney maintenance includes applying a waterproofing solution to the masonry. Additionally, other parts such as the flue, damper and cap are inspected and repaired when needed.
