COMMERCIAL INSPECTION INFORMATION

Purpose of Weep Holes Proper intake and exhaust weep holes are essential in brick commercial buildings. They allow fresh air to enter the wall cavity while moisture-laden air escapes, creating the ventilation and drainage needed to keep the wall system dry. When these weep holes are missing or blocked, moisture becomes trapped behind the brick, which can lead to major interior block wall damage, staining, and long-term deterioration.

This building experienced significant moisture damage to the interior block walls due to a lack of proper drainage and ventilation within the wall cavity. Over time, trapped moisture can result in structural deterioration, mold concerns, and costly repairs.
