High-altitude freezes every night. What does that do to masonry?
- Crown cracks that seem to grow every spring
- Joints opening on the sun-facing side first
- A chimney that ages faster than the house around it
Why it happens in New Mexico: New Mexico's adobe and kiva traditions are their own trade: rounded parapets and earthen construction that shed water differently and fail differently from brick. Add high-desert altitude (hard night freezes after warm days for months), and crown and parapet care matter more here than the modest rainfall suggests.
What fixes it, and what it costs
At altitude the freeze-thaw cycle can run nightly for months (strong sun thaws what clear nights refreeze), so condition is everything: a sound crown with an overhang, tight joints, and a breathable water repellent once they are sound. The same chimney that suffers open-jointed will shrug the altitude off maintained. The mountain supplies the test either way.
- Flexible seal over a sound crown
- $200–$500
- Localised patch repair
- $300–$700
