How We Repair Basement Leaks

We don’t believe in one-size-fits-all solutions. Depending on the cause, our team may recommend:

  • Polyurethane crack injection – permanently seals leaking cracks from the inside and includes a lifetime transferable warranty.

  • Epoxy structural repair – for larger or structural cracks needing reinforcement.

  • Drainage and grading corrections – to prevent water from returning.

  • Window well and seal repairs – to stop surface water entry.

  • Localized sump or drain tie-ins – when groundwater pressure is the culprit.

Each repair is tailored for durability, aesthetics, and long-term protection.

What causes basement leaks in St. Louis homes?

St. Louis’ expansive clay soils and wet seasons put heavy pressure on foundations, forcing water into the smallest openings. Common leak sources include:

  • Cracked foundation walls – from soil movement or settlement

  • Failed window wells or seals – letting rainwater in from above

  • Clogged or missing downspouts – forcing water against the foundation

  • Poor yard grading – keeping water trapped near basement walls

  • Hydrostatic pressure – groundwater pushing through concrete pores

Our technicians perform a detailed inspection to identify the exact source of the leak before recommending a repair.
