Missing mortar between your bricks? Loose bricks? Brick faces flaking off? Again this is strictly water damage. Before a raincap or liner is installed, an inspection of the top of the chimney is in order. This area is called the crown. The crown is subject to wear and tear from the elements such as ice, wind and rain. Once the crowns cracks, this allows an avenue for water to enter, then saturates the chimney and the freeze/thaw cycles start and wreak havoc. All chimneys wear from the top down. Once the crown is repaired and loose bricks are repaired, we can then point any bad sections of the chimney. Again we have extensive experience in this area.
