MASONRY WATERPROOFING
The Northeast is a harsh environment for masonry, as the constant freezing and thawing can create cracks in mortar joints and bricks/blocks that ruin masonry structures. To avoid this damage, a waterproofing spray can be applied to the exposed masonry. This spray makes water bead and run off the chimney instead of being absorbed into the masonry.

Common Issues
Severe deterioration or erosion is caused by water penetration. This is common in places where water can rest for a long period of time, such as a masonry wall that has snow piled up against it. Once the masonry has been repaired, a water repellant can be applied to stop any further damage.
Efflorescence
The white stains seen in the picture above are called efflorescence. It is caused by water penetrating the bricks, which causes minerals from the bricks to leach through to the outside of the chimney.
The common masonry issue known as spalling is the flaking of bricks or other masonry materials. Spalling is caused by moisture entering the masonry and is very common when chimneys or building are constructed with soft or porous bricks.
