Assessing Flood Risks

Assessing flood risks is essential in understanding and mitigating potential hazards from flooding events. By thoroughly evaluating various factors such as geographical location, historical flood data, etc., you can gain valuable insights into the susceptibility to flooding. Here are some of the important factors:

Consult flood risk resources

Assessing your home’s flood risk starts with consulting reliable resources. Begin by checking local flood maps. These maps highlight flood-prone areas based on factors such as proximity to water bodies, low elevation, and past flood events.

Next, review historical records of major floods in your community. Note the dates, severity levels, and which neighborhoods were affected.

Combining map data with historical accounts gives you a clearer understanding of your property’s flood risk. You can access flood maps through municipal websites or offices, while historical records are often available in public libraries or local history archives.

Leverage expert knowledge

Don’t face flood risks alone — involve local authorities and certified flood risk experts. They possess detailed knowledge of your area’s terrain and water patterns. You can rely on them for advice on preparation, response procedures, and effective mitigation strategies.

Flood risk experts employ advanced modeling tools to assess comprehensive risk profiles, considering factors like climate change projections. With their specialized analyses, you can make well-informed decisions to safeguard your home and loved ones.

Authorities often provide opportunities such as community meetings or consultations. Additionally, flood risk experts offer on-site evaluations tailored to specific properties. Taking advantage of their expertise can be invaluable in protecting against potential flood risks.

How to Stop Flood Water From Entering House

Stopping flood water from entering your house requires proactive measures and strategic planning. By implementing effective measures and solutions, you can minimize the risk of water infiltration. We provided the following easy steps on how to keep flood water out of your house:

Preparation and maintenance

You should start by inspecting the foundation and exterior walls for cracks or gaps and sealing them with hydraulic cement or masonry caulk. Even small openings can allow water to seep in during heavy floods.

Ensure your gutters and downspouts are clear of debris so water can flow away from the house instead of pooling around the foundation. Don’t neglect your drainage systems; keep storm drains, sewers, and underground pipes blockage-free to prevent backups.

We advise you to promptly address any issues found during inspections and consider scheduling a professional inspection annually. Remember, it’s easier to prevent flood damage than to deal with it afterward.

Flood barriers and protection

When flooding threatens, you can shield entry points with sandbags around doors, windows, and vents to block water. These act like temporary walls. 

Additionally, floodgates and door dams can seal doorways, adding extra protection. You can use rigid aluminum or plastic shields that cover the entire opening — they’re highly effective for windows.

Inside your home, installing a sump pump in the basement can automatically remove any water that manages to get inside. We advise you to have sandbags and other materials stored beforehand and establish an emergency plan with your family. When setting up barriers, you must prioritize safety and ensure everything is secure.

Landscaping and external measures

The landscaping around your home is also important. Make sure your yard is graded properly so it slopes downward away from the foundation. This will divert excess water away instead of letting it pool against the house.

You can also install shallow swales or trenches lined with gravel. These guide water away from vulnerable areas. Rain gardens with deep-rooted native plants absorb and store rainwater during storms, reducing runoff.

Moreover, we recommend opting for permeable pavers or porous concrete surfaces. They allow water to seep through rather than flow over, minimizing water accumulation. Installing a dry well or underground tank can also help manage excess water.

Emergency Measures

When faced with rapidly rising flood waters, you must act swiftly to build temporary barriers to keep water out of your home. Start by using sandbags — fill them with sand or soil and stack them tightly around doors, windows, vents, and any openings.

If you don’t have sandbags, you can improvise by blocking entryways with household items like bricks, lumber, towels, or furniture. We suggest sealing gaps with plastic sheeting and tape for added protection.

Additionally, you should use tools like shovels, hammers, and nails nearby to speed up barrier construction. Begin from higher ground and work downwards, regularly checking for leaks or weak spots that require reinforcement.

Plus, try to redirect flowing water away from your property by using sandbags or digging trenches. And prioritize safeguarding critical areas like basement entrances first.

Emergency preparedness and evacuation planning

Preparedness is crucial, so you should assemble emergency kits in advance. These kits should include flood supplies such as sandbags, tarps, rope, and tools. 

We advise you to keep them in an easily accessible spot and replenish them regularly. Also, pack a portable “go” bag with meds, cash, important papers, snacks, and water for quick evacuation if needed.

In addition, familiarize yourself with your community’s evacuation routes and emergency shelters. Establish a household communication strategy, including meeting spots and a contact person outside the area. And don’t overlook planning for your pets’ safe evacuation.

Remember to review and practice your plan annually to ensure everyone knows what to do. Stay alert to weather changes and act swiftly if evacuation orders are issued in your area.


Preparedness is essential when facing and learning how to stop flood water from entering house. As noted, you can safeguard your home against water intrusion by implementing proactive and last-minute measures. From sealing entry points and maintaining drainage systems to deploying temporary barriers like sandbags, every step counts.

Remember also to assess your flood risks, involve local experts, and stay informed to protect your property effectively. With careful planning and swift action, you can minimize damage and ensure the safety of your home and loved ones during flood events.
