The short answer
First Steps After the Storm
Start by looking at the outside of your foundation. Walk around the entire perimeter and note any cracks, gaps, or areas where the soil has pulled away from the wall. Check for standing water near the base, as prolonged moisture can weaken the soil and put pressure on the foundation.
Inside, inspect the walls and floors for new cracks or widening of old ones. Pay attention to doors and windows that stick or no longer close properly, as these can signal movement. If you see water stains or feel dampness on interior walls, that is a sign that water has entered the structure.
Signs of Serious Damage
Some cracks are cosmetic, but others indicate structural problems. Horizontal cracks, especially in a stair-step pattern, are more concerning than vertical ones. A foundation that has shifted or settled unevenly may show as a gap between the wall and the floor or ceiling.
Look for bowing or bulging in the foundation walls, which can happen when soil expands and pushes against the concrete. If you notice any of these signs, do not enter the area if it looks unsafe. A professional water damage inspection can assess the severity and recommend next steps.
- Cracks wider than a quarter inch
- New or expanding cracks after the storm
- Doors or windows that stick
- Gaps between walls and floors or ceilings
- Water pooling near the foundation
- Musty odors or dampness in the basement
What Causes Foundation Problems
Heavy rain can saturate the soil around your home, causing it to expand and contract. This movement puts pressure on the foundation and can lead to cracking or shifting. If your gutters and downspouts do not direct water away from the house, the problem gets worse.
In a semi-arid climate with cold winters and hot dry summers, the soil can dry out and shrink, then swell with moisture. That cycle stresses the foundation over time. Debris from the storm, like fallen branches, can also block drainage and cause water to pool against the walls.
When to Call the Pros
If you see any signs of foundation damage, do not wait. Water that seeps into cracks can freeze and expand, making the damage worse. The pros can perform a thorough inspection and use moisture mapping to find hidden water that is not visible to the eye.
They can also help with foundation stabilization if the soil has shifted. In the meantime, you can take steps to reduce further water intrusion, such as clearing debris from gutters and ensuring the ground slopes away from the house. If the storm left standing water, emergency water extraction may be needed to prevent more damage.
Protecting Your Foundation
Prevention is the sensible way to keep your foundation safe. Keep gutters and downspouts clear so water flows away from the house. Consider extending downspouts at least a few feet from the foundation. If you live in Caldwell, you can also check that your yard grading directs water away from the home.
After a storm, inspect the area around the foundation for new cracks or movement. If you notice anything, have a water damage inspection done before the problem worsens. Foundation waterproofing can help protect against future water damage, and structural drying and dehumidification can address any moisture that has already entered.

How soon after a storm should I check my foundation?
Check as soon as it is safe to go outside. The longer water sits against the foundation, the more damage it can cause. If you see cracks or shifting, call the pros for an inspection within a day or two to prevent further issues.
Can I fix foundation cracks myself?
Small hairline cracks may be sealed with a concrete patching compound, but larger cracks or those that indicate movement need professional attention. A pro can determine if the crack is structural and recommend the right repair, such as foundation stabilization.
Will my insurance cover foundation damage from a storm?
Policies vary, and your insurer decides what is covered. Some storm-related water damage may be covered, but flood damage often has separate rules. Check your policy and talk to your insurance company to understand what is included before you start repairs.
