Baked all summer, soaked all winter. Which season broke the crown?
- Hairline crown and joint cracks appearing by autumn
- Damp staining after the first winter rains
- Damage that looks like freeze country without the freeze
Why it happens in Sacramento: The Central Valley cycle is bake-then-soak: a long rainless summer that dries mortar out and opens hairline cracks, then months of winter rain and tule fog sitting on masonry that has just spent half a year cracking open. The damage pattern looks like freeze-thaw without the freeze, and the season to fix it is the dry one, when the masonry is at its driest and repairs cure fast.
What fixes it, and what it costs
The valley cycle (a rainless summer that dries and cracks, then months of rain and fog on masonry that just opened) mimics freeze damage without frost. The repair calendar writes itself: crown and joint work in the dry season when cure is fast and the masonry honest, water repellent after, and the winter arrives with nothing open to find.
