Corroded chimney caps letting water and debris in
Why it happens here
Salt spray off Lyall Bay Beach attacks metal caps year round. Once the cap corrodes, rain runs down the flue and nesting material gets in. The result is a blocked flue, chimney odor and a damaged flue liner.
Our approach
We inspect the cap on every Lyall Bay visit and fit a stainless replacement rated for coastal conditions when needed. We also check the crown and flashing at the same time so water has nowhere else to get in.
