Every spring I notice new cracks in my chimney that I swear weren’t there before winter. Is winter actually causing that?
Answer
That’s pretty typical. We see it all the time on chimneys in Clarkston. What’s happening is water gets into small cracks or mortar joints, and once temperatures drop, that water freezes and expands. That expansion puts pressure on the surrounding brick and mortar.
The problem is it doesn’t just happen once — it repeats over and over throughout the winter. Each cycle makes those cracks a little bigger. By the time spring comes around, what started as a small crack can turn into something much more noticeable. If it’s left alone, it’ll keep getting worse each season, so getting it repaired helps stop that cycle before it leads to more serious chimney damage.
