Almost every home has a few foundation cracks, and most are harmless. The trick is knowing which ones are cosmetic and which ones point to a structural or drainage problem.
Key takeaways
- Thin vertical cracks are usually normal shrinkage.
- Horizontal cracks and stair-step cracks deserve closer attention.
- Most foundation problems trace back to water and grading.
Cracks that are usually fine
Hairline vertical cracks in poured concrete are common as the foundation cures and the house settles. They're worth monitoring but rarely a structural concern on their own.
Cracks that warrant a closer look
Horizontal cracks, stair-step cracks in block walls, cracks wider than a quarter inch, or any crack with displacement can indicate pressure from soil or water. These we flag for further evaluation.
It usually comes back to water
Poor grading, short downspouts, and clogged gutters send water against the foundation. Fixing drainage is often the cheapest, most effective step a homeowner can take.
