A leak evidence timeline in Windsor: record events, not estimates

Exact Source · 19 October 2026 · 2 min read

A useful leak record is more than a folder of photographs. The timing of a stain, alarm, repair or test can change how the evidence is interpreted, so a Windsor property owner should build a simple chronology while memories and files are still fresh.

Start with events you can date

Record the first sign that was actually noticed, not a guessed start date for the leak. Note the date and time, who saw it, where it appeared and whether water was still present. Add later events such as isolating a stop tap, calling a managing agent, moving contents, arranging an emergency repair and attending an investigation.

Use original sources where possible: a time-stamped photograph, an email, a meter photograph, a contractor arrival message or an invoice. If someone only remembers that an event happened ‘around the weekend’, label it as an approximate recollection rather than converting it into a precise date.

Separate observation from explanation

A timeline should say ‘water mark first photographed at 08:14’ rather than ‘pipe began leaking at 08:14’. The first is supported by the file; the second is a conclusion that may require testing. Likewise, ‘heating pressure was lower on Monday’ is different from ‘the heating circuit caused the mark’.

This distinction matters when a concealed leak may have developed before visible damage. Financial Ombudsman case material shows that decisions about gradual damage turn on the evidence and on when a policyholder could reasonably have known about a problem, rather than simply on the age of hidden damage.

Keep the chronology usable

Give every image and document a short identifier, then refer to it in the timeline. Keep the unedited original files as well as any annotated copies. If a date is corrected, retain the earlier entry and show the reason for the correction so later readers do not mistake two versions for two separate events.

Share the timeline with the investigator before the visit if it contains intermittent symptoms or earlier repairs. A professional assessment is still needed to test the source; the chronology helps that assessment focus on the right period, system and operating conditions.

Finish the chronology with its preparation date and the name or role of the person who assembled it. If another resident, contractor or agent supplies an entry, attribute it. This prevents a later reader from assuming that every line was personally witnessed by the same person.
