It is very important to see the signs of deterioration before they become a bigger problem; here is a few things to look out for:

 

Main Causes

 

Leaking eavestrough/ roof

One of The major factors for the deterioration of masonry structures is water; not clean pure rainwater but the water that has sat and collected salts and minerals, then deposited onto the masonry. Most commonly, a leaking eavestrough. The salts get left behind and form efflorescence (shown as a white powder on the surface); this eats the bricks clay surface and causes spalling.
