What is likely happening
Spalling usually means water has got into the material and frozen, or steel inside has corroded and expanded. It tends to get worse every winter.
What you can safely check
- Look for rust stains or exposed rebar.
- Note areas above sidewalks and entrances first.
What an inspector will look at
- Extent and depth
- Embedded steel
- Loose material that needs removal
Does this affect compliance?
Spalling above public areas is typically an unsafe condition under facade ordinances.
When it becomes urgent
Urgent where it is above a sidewalk, entrance or play area.
