What can be a consequence of inadequate air circulation in brick walls?

Inadequate air circulation in brick walls can lead to increased moisture buildup. When air cannot move freely, moisture that enters the wall system has difficulty evaporating. This trapped moisture can result in several problems, such as mold growth, deterioration of the brick and mortar, and damage to insulation materials. Over time, persistent moisture buildup can compromise the structural integrity of the wall, lead to spalling of bricks, and create an inviting environment for pests. Proper ventilation is crucial to promote adequate airflow, which helps to manage moisture levels and prolong the lifespan and performance of the brickwork. In contrast, the other options do not directly correlate with the effects of inadequate air circulation.
