Cold weather can make existing foundation cracks worse — or make new ones appear seemingly overnight. If you’ve spotted a crack this winter, the big question is: Is this serious?
Not all cracks are a red flag. But some point to deeper structural issues that require immediate attention. Here’s how to tell the difference and what to do next.
Why Cracks Happen More in Winter
Winter brings a mix of cold temperatures, moisture, and soil movement. This creates stress on your home’s foundation in a few key ways:
Freeze–Thaw Cycles: Moisture in the soil expands when it freezes, pressing against your foundation walls. When it thaws, the soil shifts again — leading to movement and cracking.
Settling from Saturated Soil: After heavy rain or snow, wet soil can no longer support your foundation evenly, causing cracks from uneven settlement.
Dry Air Inside the Home: Lower humidity inside during the winter can cause wood framing to shrink, which may lead to hairline cracks in drywall — these are usually cosmetic, not structural.
When to Worry About a Foundation Crack
Not every crack spells disaster, but certain signs should prompt a call to a foundation expert:
🚩 Cracks Wider Than 1/8 Inch
Wide or growing cracks suggest ongoing movement and possible structural failure.
🚩 Horizontal Cracks in Basement Walls
These are often caused by external soil pressure and can indicate serious damage to the wall’s integrity.
🚩 Stair-Step Cracks in Brick or Block
This pattern often points to foundation settling or shifting, especially in corners of the home.
🚩 Water Seepage Through Cracks
Any crack that lets in water during winter should be taken seriously, as moisture accelerates deterioration.
When Not to Worry (But Still Watch)
✅ Hairline Vertical Cracks: Often due to normal concrete curing, especially in newer homes.
✅ Minor Drywall Cracks Above Doors: These are often caused by seasonal humidity changes and may not be structural.
✅ Stable, Non-Growing Cracks: If a crack hasn’t changed over time, it’s likely not a sign of active movement — but still worth monitoring.
