Chimney leaks from cracked flashing and crumbling crowns
Why it happens here
Nor'easters and freeze-thaw cycles damage flashing and crowns on Commercial Street District chimneys. Older buildings on Liberty Street and Union Street are especially vulnerable. Water gets in and causes ceiling stains and masonry damage.
Our approach
We inspect flashing and crowns with inspection cameras. We replace cracked flashing with copper or stainless steel. We rebuild crumbling crowns with chimney crown mix and apply water repellent from ChimneySaver to prevent future leaks.
