Common Causes of Basement Flooding
Before you can prevent flooding, it’s important to understand what causes it. Here are the most common culprits:
Poor Drainage Around the Foundation
When the soil around your home doesn’t drain properly, water can collect and seep through cracks in the foundation walls.

Clogged or Broken Gutters and Downspouts
Gutters that are filled with debris or misaligned downspouts can cause rainwater to overflow and saturate the ground near the basement.
Cracks in the Foundation or Basement Walls
Structural foundation cracks are common in homes across St. Louis, especially those built on expansive clay soils. These cracks create pathways for water to enter your basement.

Improper Grading
If the ground around your home slopes toward the foundation rather than away from it, rainwater will naturally flow toward your basement.
Sump Pump Failure
A malfunctioning or overwhelmed sump pump can lead to serious basement flooding, especially during periods of heavy rainfall. Lack of proper sump pump maintenance can worsen these issues.
How to Prevent Basement Flooding: Proactive Steps for Homeowners
- Keep Gutters and Downspouts Clear: Regularly clean your gutters and ensure downspouts direct water at least 6 feet away from your foundation. Extensions or splash blocks can help prevent water from pooling near your home.
- Maintain Proper Grading: Make sure the soil around your home slopes away from the foundation. If needed, regrade the landscape to promote proper runoff.
- Seal Foundation Cracks: Inspect your basement walls and foundation regularly for cracks. Small cracks can be sealed with waterproofing compounds, but larger or structural cracks should be repaired by professionals like our team at Cornerstone.
- Install or Upgrade Your Sump Pump: A high-quality sump pump with a backup power source is essential for homes in flood-prone areas. If you already have a sump pump, test it regularly to make sure it’s functioning properly.
- Use a French Drain or Drain Tile System: Installing a French drain or an interior drain tile system can help redirect groundwater away from your basement. These systems are especially effective for homes with persistent water intrusion issues.
- Waterproof Basement Walls: Apply waterproof coatings to basement walls to help keep moisture out. For long-lasting protection, professional basement waterproofing is recommended.
- Inspect Plumbing and Appliances: Leaking pipes or faulty appliances can also lead to basement flooding. Check your water heater, washing machine, and basement plumbing regularly for leaks or signs of wear.

FAQs About Preventing Basement Flooding
How do I know if my basement is at risk for flooding?
If you notice damp walls, musty odors, or water stains, your basement may be vulnerable to flooding. Homes with poor drainage or cracks in the foundation are especially at risk.
Is basement waterproofing worth the investment?
Yes. Waterproofing protects your home’s structure, prevents mold growth, and preserves property value. It also saves you money in the long run by avoiding costly water damage repairs.
How often should I check my sump pump?
It’s a good idea to test your sump pump every few months, especially before heavy rain seasons. Ensure it turns on automatically and discharges water efficiently.
Can landscaping help prevent flooding?
Absolutely. Planting grass or native plants with deep root systems can help absorb excess water. Avoid planting trees too close to the foundation to prevent root damage and soil shifting.
