Question 1

What types of foundation cracks are most dangerous?

Accepted Answer

Horizontal cracks are the most serious — they indicate lateral soil pressure and can signal imminent structural failure. Stair-step cracks in brick mortar and wide vertical cracks over 1/4 inch also warrant immediate professional evaluation. Hairline cracks under 1/16 inch are usually just normal concrete shrinkage.

Question 2

How do I know if my foundation crack is getting worse?

Accepted Answer

Mark the ends of the crack with pencil and note the date, then check back in 2–4 weeks. If the crack has grown or widened, it is active and needs professional attention. Other signs of worsening include doors and windows that stick, uneven floors, and gaps between walls and ceilings.
