Flooding can cause significant damage to homes and properties. Preparing your home to withstand flood conditions can help minimize damage and save on repair costs. Read our quick and easy guide to help you flood-proof your home.

1. Understanding Flood Risks

Assess Your Flood Risk

  • Check Flood Maps: Consult flood maps to understand the flood risk in your area.
  • Historical Data: Investigate past flooding incidents in your area.
  • Local Authorities: Contact local government offices for information on flood risks and recommendations.

2. Structural Modifications

Elevate Your Home

  • Foundation: Raise the foundation of your home above the base flood elevation level. This is often necessary for homes in high-risk areas.
  • Basements: Avoid having basements in flood-prone areas. If you have one, ensure it is properly waterproofed.

Flood Barriers

  • Floodwalls and Levees: Construct barriers around your property to prevent water from entering.
  • Sandbags: Use sandbags as a temporary measure to divert water away from your home.

Install Flood Vents

  • Flood vents help water flow through enclosed spaces, to reduce pressure on the structure and prevent damage.
  • Installation: Install at least two vents on different walls of enclosed spaces.

3. Protecting Utilities and Systems

Elevate Electrical Systems

  • Electrical Panels: Move electrical panels, sockets, and wiring at least one foot above the base flood elevation.
  • Backup Power: Install a generator on an elevated platform to ensure power during a flood.

HVAC Systems

  • Relocation: Place HVAC units on an elevated platform or in the attic.
  • Protective Barriers: Install barriers around the units to protect them from floodwaters.


  • Backflow Valves: Install sewer backflow valves to prevent floodwater from backing up into your home through the drains.

4. Landscaping and Drainage

Slope the Yard

  • Grading: Ensure the yard slopes away from your home to direct water flow away from the foundation.

Rain Gardens

  • Purpose: Rain gardens absorb and filter rainwater, reducing runoff.
  • Plants: Use native plants with deep roots that can withstand wet conditions.

French Drains

  • Installation: Install French drains around your property to channel water away from your home.

5. Interior Modifications


  • Sealants: Apply waterproof sealants on walls and floors in basements and other areas that may risk of flooding easily.
  • Flood-Resistant Materials: Use materials like tile, concrete, and waterproof wallboard in areas prone to flooding.

Furniture and Belongings

  • Elevation: Keep valuable items and electronics on higher floors.
  • Quick-Release Systems: Use quick-release systems for easily movable furniture.

6. Emergency Preparedness

Flood Alerts

  • Notifications: Sign up for local flood alerts and weather notifications.
  • Emergency Kit: Prepare an emergency kit with essentials like water, food, medications, and important documents.

Evacuation Plan

  • Routes: Plan and practice evacuation routes.
  • Meeting Points: Establish meeting points for family members.

7. Flood Risk Insurance

Importance of Flood Insurance

  • Cover: Standard home insurance policies typically do not cover flood damage. Flood insurance is essential to protect your investment.
  • Recovery: Helps cover the cost of repairs and replacements after a flood.
