The short answer
How Storm Water Affects Your Foundation
Heavy rain from a storm can soak the ground around your home. In a semi-arid climate with cold winters and hot dry summers, the soil may be dry and cracked before the storm, so sudden moisture can cause it to expand unevenly. This expansion pushes against your foundation and can make parts of the house rise or settle.
When the soil dries out again, it shrinks and leaves gaps under the foundation. That movement, called differential settlement, is what makes a house shift. You might see cracks in drywall, doors that stick, or gaps around windows. These are signs that the ground beneath your home is moving.
Wind and Falling Trees
Strong winds during a storm can push against the walls of your home, especially if the roof is large or the house is tall. Over time, repeated wind pressure can loosen connections between the framing and the foundation. This is more likely in older homes or those built on less stable ground.
Falling trees or large branches can also strike the house and cause sudden shifting. Even if the impact seems minor, the force can crack the foundation or push a wall out of square. After any storm with high winds, walk around your home and look for fresh cracks or leaning walls.
- Check for new cracks in interior walls and ceilings
- Look at the exterior foundation for visible gaps or splits
- Notice if doors or windows stick or no longer latch
- Inspect the roofline for a wavy or sagging appearance
- See if the ground around the foundation has pulled away
- Watch for water pooling near the base of the house
What to Do Right After a Storm
If you suspect your home has shifted, start by documenting the damage. Take photos of any cracks, gaps, or leaning walls before you clean up. This record helps you track whether the movement is getting worse over the next few weeks.
Clear debris away from the foundation so water can drain away from the house. If you live in Caldwell, keep your downspouts extended and make sure gutters are not clogged. Acting quickly can prevent further water from seeping into the soil and making the problem worse.
When to Call the Pros
Some shifting is minor and may settle on its own once the soil dries out. But if you see large cracks, a door that no longer closes, or a visible lean in a wall, you need a professional assessment. Local water damage pros can evaluate the extent of the movement and recommend the next steps.
A water damage inspection can identify moisture issues that contribute to soil movement. If the foundation has shifted, you may need structural drying or dehumidification to reduce moisture in the soil. The pros can also help with debris removal after a storm to reduce weight and pressure on the structure.
Preventing Future Shifts
You cannot stop storms, but you can reduce the risk of shifting by managing water around your home. Make sure the ground slopes away from the foundation so rain flows away instead of pooling. Install gutters and downspouts that carry water at least a few feet from the house.
In dry periods, water the soil around the foundation lightly to keep it from becoming too dry and shrinking. This is especially important in a semi-arid climate. If you have large trees near the house, have a professional trim branches that could fall during a storm and damage the structure.

How can I tell if my home has shifted?
Look for new cracks in drywall or plaster, doors that stick or do not latch, and gaps between walls and ceilings. Outside, check for cracks in the foundation or a visible lean in the roofline. These signs often appear within days after a heavy storm.
Is shifting covered by my insurance?
Policies vary, and your insurer decides what is covered. Storm damage to your roof or siding may be covered, but ground movement like settlement or heaving is often excluded. Check your policy and talk to your insurance company to understand what applies to your situation.
Can I fix a shifted foundation myself?
Minor cracks can be filled with caulk or mortar, but real shifting requires a professional. Trying to level a foundation without the right equipment can make it worse. A structural engineer or a water damage pro can tell you if the movement is serious and what repairs are safe.
