A cracked and/or deteriorated
masonry chimney crown
will allow rainwater to penetrate into the chimney structure and cause damage to
the mortar joints and bricks, and over time can affect the integrity of the
chimney structure. The chimney crown's deterioration is generally caused by its
exposure to the sun and Mother Nature. By applying a flexible crown sealer
that is 100% Weatherproof, it will add many years to the life and overall
condition of the chimney. Our recommendation is Flexible Crown. |
