The same chimney crack 'coming back' every spring?
- A repaired crack that reopens after each winter
- Caulk and patch repairs that last one season
- Sixty-degree temperature swings inside a week
Why it happens in Missouri: Missouri's temperature swings are violent, sixty-degree drops in a day, and for masonry that whiplash is worse than steady cold. The freeze-thaw cycle runs on fast-forward, flexible patches fail first, and the same crack 'returns' every spring because it never left.
What fixes it, and what it costs
Whiplash weather runs the freeze-thaw engine on fast-forward and defeats flexible patches first: the crack never left, it just moves with the seasons. The repair that holds is the structural one: joints raked and repointed with matched mortar, crowns recast rather than caulked, done in a settled stretch of weather so the cure completes before the next swing.
