What causes basement and foundation problems in Saint Louis?
Brick and stone foundations
Old brick foundations lose mortar and leak; repointing with the right mortar matters.
Clay soil movement
Clay shrinks and swells with moisture, causing cracks and settlement.
Sinkholes in karst areas
Parts of the region sit on limestone with sinkhole risk; settlement cracks should be assessed by an engineer.
Combined sewer backups
Older sewers can back up in heavy rain; backwater valves protect basements.
Brick bungalow porches and areaways
Many south city bungalows have front porches and stairwell areaways that drain right at the foundation; clogged areaway drains are a common source of basement water.

What do Saint Louis homeowners ask most?
Why does my Saint Louis brick basement leak?
Old brick and soft mortar let water through. Repointing, gutters and interior drainage usually fix it.
Does MSD help with sewer backups?
The Metropolitan Sewer District has run programs for backwater valves in some areas. Check current offerings with MSD.
Is settlement common in Saint Louis?
Clay movement and old foundations make some settlement common. Fast-growing cracks deserve an engineer's look.

It is the drain at the bottom of an exterior basement stairwell. When it clogs, rain pools against the basement door and wall. Clearing or replacing it is a cheap first fix.
