Chimney leaks from failed flashing or cracked crown
Why it happens here
Kirkwood gets plenty of rain, and the flashing around the chimney is the weakest point. Over time it rusts or pulls away. The crown also cracks from freeze-thaw cycles. Water finds the gap and runs inside.
Our approach
We replace the flashing with new copper or aluminum and seal it. We repair or replace the crown with a sloped pour. Then we waterproof the brick. This three-part fix stops the leak and protects the chimney.
