Home-problem library
Visible home problems: what to document next
A stain, crack, odor, or damaged component is a clue—not a diagnosis. Use this library to document context and choose the right professional follow-up.

Use visible clues responsibly
- Capture a wide view, close view, and scale reference.
- Note location, weather, operation, odor, sound, and apparent repairs.
- Do not disturb suspect hazardous materials or enter unsafe spaces.
- Ask a qualified professional to determine cause, severity, and scope.
