Crack in the foundation wall
Likely cause, what to safely try first, and whether it gets worse if you wait.
Likely cause
Normal settling, or water pressure/freeze-thaw widening it over time.
What to try first
- Measure the crack's width and check if it's growing — photograph it monthly with a coin for scale.
- Note if water comes through it during heavy rain — that changes the urgency and repair approach.
⚠ This tends to get worse (and more expensive) the longer it's left unaddressed — worth acting on soon.
