Why Is Coastal Storm Damage Different From Inland Flooding?

Water from a coastal storm can be driven by hurricane or nor'easter winds, creating a powerful surge. That surge can push ocean water far inland. Its force can damage structures directly. Inland flooding often rises more slowly from heavy rain or an overflowing river. The slower rise may allow more time to move to safety, but the water still causes deep saturation and stress on a home's foundation and walls.

Flood water is rarely clean. Inland flooding often picks up contaminants from lawns, streets, and agricultural areas, including fertilizers and pesticides. Coastal flooding introduces marine contaminants and may mix with sewage from overwhelmed coastal infrastructure. Identifying the contaminants is a key step for the pros, as it dictates the safety protocols and cleaning methods required for your property.

• Sewage and chemical runoff from overwhelmed systems
• Sand, silt, and mud deposited by moving water
• Debris like branches, trash, and building materials
• Salt, marine organisms, and pollutants in coastal water
• Fuel or hazardous materials from flooded vehicles or tanks
• Mold spores that begin growing within 24 to 48 hours

The pros tailor their response to the water type. For salt water, they focus on thorough rinsing and corrosion control. For inland fresh water, the priority is rapid extraction and drying to prevent mold. Local climate conditions, like high humidity, can make drying more challenging. Specialized equipment is used to manage indoor humidity effectively.

• Assessing for salt corrosion on metal fixtures and wiring
• Flushing and cleaning systems to remove silt and sand
• Using antimicrobial treatments appropriate for the water category
• Monitoring humidity levels closely in a humid subtropical climate
• Possibly replacing drywall and insulation higher up the walls
• Coordinating with your insurance adjuster for documentation
