For a ring-shaped stain by a window, ask when it was first seen, what work followed and whether it returned in the same place. With permission, take a room view and a close-up. Keep the mark you saw, the repair evidence supplied and the unknown cause as separate entries.

Window-mark follow-up record
This fictional record labels the source of each item so it can be checked on the next visit.
| Location | Evidence this visit | Next check |
|---|---|---|
| Bedroom 2, below sill | Pale outline photographed on a dry Saturday. | Repeat from the same position and angle. |
| Living-room frame | Work order records resealing last month. | Ask for the bedroom’s own record. |
Sources and instructions
What should I record about fresh paint or a window stain?
Give the room a code such as Bedroom 2, bottom-left of window. From a safely accessible position, note color, extent, nearby finishes and weather. Include a fixed reference such as the frame in the wider photograph. Fresh paint describes the surface; an old stain alone does not establish an active leak.
What should I check when told a problem was repaired?
Check location, work and date. Resealing a frame and repainting a wall are different jobs. Match the record to this window and ask who did what, when and whether it was checked afterward. With consent, view a redacted work order or before-and-after photos. Label an unsupported account as verbal and keep its scope open.
Can a photo of a crack establish structural safety?
A photograph alone is insufficient. Tell a qualified on-site professional which wall is affected, where the mark sits relative to a column, beam or finish joint, and whether anything is flaking. Hong Kong’s Buildings Department distinguishes cracks, concrete spalling and seepage among common defects. Keep clear of loose or falling material and tell management.
Example: what remains unknown after two visits?
On a sunny Saturday you see a pale stain below the Bedroom 2 sill. A work order from last month covers the living-room window. After rain the following week, the outline looks similar. Record: bedroom mark still visible; order concerns living room; bedroom repairs and source unknown. Ask for evidence for that location rather than inferring the leak point from the photos.
