What to notice
Identify whether the slope is gradual or localized, whether it is new, and whether nearby doors, walls, or finishes have changed.
Elevation measurements
Relative floor elevations can help identify patterns, but measurements are most useful when interpreted with the structure and visible symptoms.
When to investigate
Growing changes, abrupt localized dips, or uneven floors combined with cracks and sticking openings deserve closer evaluation.
