A home inspector can easily identify the signs of problems in brick veneer. Weep holes can become blocked and not allow water to exit from behind the bricks, leading to deterioration of the brick and mortar. Additionally, brick ties can be improperly installed or loosened over time, and the veneer can separate from the wall. Separation or detachment from the wall is the most important thing to inspect for with brick veneer. Looking along window and door openings, you might see the lean of detached veneer, meaning more brick shows at the top than at the bottom. A detaching veneer may have a decided bow to it or can show signs of cracking as it pulls loose and separates from the house.
As with solid brick walls, the home inspector should examine the wall for cracking in the brick and deterioration of brick and mortar. Examine weep holes in the lower course of bricks in the veneer to be sure they are open as water behind the wall cannot escape if weep holes are blocked. Often times there is brick veneer on only a portion of the house, so be sure to check areas where the veneer meets other surfaces.
