Over time, bricks on your house or building may become loose or separate from the structure at that point the bricks will need to be replaced. Common signs that an area needs to be rebuilt or relayed are bricks that are severely damaged or spalled including large sections of walls that are wavy or tipping. Chances are good the conditions have gone unnoticed for a long time or an inadequate repair job was performed in the past. Unfortunately, when conditions get to this point, it is considerably more expensive to repair than if the job had been tuckpointed.
