Crown damage from freeze-thaw cycles
Why it happens here
Centennial Neighborhood sees 30 to 40 freeze-thaw cycles each winter. The original concrete crowns on these homes were often thin and unreinforced. Water gets into small cracks, freezes, expands, and breaks the crown apart. After 15 to 20 years, most crowns here are cracked or crumbling.
Our approach
We remove the failed crown and form a new one with chimney crown mix, built with a proper overhang and slope. We cure it correctly and seal the joint. This stops the leak at the top and prevents the interior water damage that follows.
