How Flood Damage Affects Home Foundations in Metairie, Kenner & Harahan

How Flood Damage in Metairie, Kenner & Harahan Affects Your Home’s Foundation 

Flooding is an all-too-common reality for homeowners in Metairie, Kenner, and Harahan. With frequent tropical storms, heavy rains, and low elevation, these areas are especially vulnerable to water damage—and one of the costliest consequences is damage to your home’s foundation. 

Understanding how floodwaters affect your foundation—and what you can do to protect it—can save you thousands in foundation repairs and preserve the long-term safety of your home. 

Why Flooding is a Major Risk in Metairie, Kenner, and Harahan 

Local Flood History and Patterns 

Situated near the Mississippi River and Lake Pontchartrain, homes across Jefferson Parish are in a high-risk flood zone. Local drainage systems can be overwhelmed during storms, and the area’s low-lying geography makes standing water a frequent problem. Even just a few inches of water can penetrate soil layers and begin to destabilize foundations. 

How Floodwaters Damage Foundations 

Soil Expansion and Erosion 

Floodwaters saturate the ground around your home. As soil swells, it puts pressure on the foundation slab or piers. When water recedes, the soil contracts—creating voids underneath. Over time, this cycle causes cracks, shifting, and destabilization. 

Slab vs. Raised Foundation Vulnerabilities 

Slab foundations, common in Louisiana, are especially prone to water pooling and slow drainage, which can lead to cracking or shifting. Raised foundations (pier-and-beam) may fare better in floods but still suffer from erosion and moisture intrusion in crawl spaces. 

Signs of Foundation Damage After Flooding 

Cracks, Moisture, Sloping Floors, Musty Smells 

After a storm or flood, watch for these warning signs: 

• Cracks in walls, bricks, or floors 
• Uneven or sloping floors 
• Doors or windows that stick 
• Musty smells or visible mildew 
• Standing water in crawl spaces or around the foundation 

If you notice any of these, it’s time to schedule a professional inspection. 

What to Do After a Flood 

When to Inspect, What to Look For, and When to Call Abry
