Ask for an inspection report that separates observation from diagnosis

Specify the area, evidence and limits of a property inspection before treating a collection of photographs as a repair plan.

MichaelT23 October 2026

Describe the question and the accessible scope

Write what you want the inspection to clarify and which area it concerns. Ask the provider to define the agreed method, access arrangements, competence and exclusions. Do not enter an unsafe area, climb a roof or disturb a material to complete this worksheet. A roof image, drain-camera recording and building survey have different scopes; a generic service name cannot establish that all of them are included.

Give evidence a location and an identifier

Ask for each observation to be linked to a photograph, clip or report reference and an identifiable area. If a clip is supplied, a time reference can help distinguish one observation from another. Keep observed condition separate from a proposed cause, a repair recommendation and a cost. A wet mark might be visible; its source may require further investigation. Neither an attractive photograph nor confident wording resolves that difference.

Read the limits as part of the result

Record areas not seen, unsuitable viewing conditions and the provider’s stated limitations. An inaccessible section should remain unknown. Ask which additional investigation, if any, is recommended and who is competent to interpret it. Do not translate no visible defect in the observed area into whole-building structural safety, no asbestos, no mould or a guarantee against future leaks.

Connect the next decision to the actual report

When a quote follows, match each proposed work item to the relevant observation or assessment. Ask about unexplained work and separate investigation from repair. Retain the report version and date with the quote so a later decision is not based on an older image. Completion, certification and any agreed follow-up observation need their own evidence; they are not implied by paying for the inspection.

Visible does not mean complete: Photo P3 records a mark in area R. An unobserved rear area stays unknown. The observed mark is not a diagnosis of its cause or proof of a completed repair.

Photo P3 records a mark in area R. An unobserved rear area stays unknown. The observed mark is not a diagnosis of its cause or proof of a completed repair.

Work through an example

In a fictional roof report, photo P3 shows a mark beside area R. The report says the rear section was not visible from the agreed position. The owner records the mark as an observation, leaves its cause open and asks what further assessment would answer that question. A separate repair quote cannot close the unseen-area row merely by describing the roof as restored.

Illustrative example; figures, people and organisations in the worked record are fictional.

Use the result within its scope

This is a report-reading method, not an inspection or remediation procedure. Actual access, diagnosis, testing and work require the appropriate competent assessment. Keep the scope narrower than the conclusions the evidence can support.

Add a dated moisture-observation log to the inspection enquiry

Give the professional a sequence of observations without turning a damp mark into a diagnosis of its source.

Use a repeatable reference

From a safe accessible position, assign the observed area a reference and keep the date, time and viewpoint. If a photograph is appropriate, avoid personal or neighbouring details. Describe what was visible rather than declaring a structural, plumbing or waterproofing fault. Do not open walls, enter unsafe areas or disturb a suspect material to improve the picture.

Keep context and cause separate

Record known context such as observed rain or a relevant event, identifying where that information came from. A wet mark seen after rain is a timing association, not proof of an entry path. EPA’s moisture guidance explains the importance of addressing moisture; it does not diagnose a particular property from a notebook. Follow appropriate professional advice for a real moisture or health concern.

Hand over the sequence with its gaps

Keep the earlier and later observations under the same area reference and preserve unobserved periods. Ask the competent inspector what further assessment could answer the specific question. A later dry-looking photograph does not prove the cause was repaired or certify the area free of mould. This addition supplies no cleanup, drying, chemical treatment or drainage design.

A sequence retains its gaps: The fictional moisture log preserves an unobserved day. Timing after rain and a later appearance do not establish the cause or a completed repair.

The fictional moisture log preserves an unobserved day. Timing after rain and a later appearance do not establish the cause or a completed repair.

Work through an example

A fictional log notes a visible mark at area R after observed rain on date D1. D2 has no observation; D3 records a changed appearance from the same safe viewpoint. The sequence is given to a competent inspector with D2 marked missing. No leak path, exposure, mould status, structural condition or completed repair is inferred.

Use the result within its scope

Use the log as supporting context for the actual assessment. It cannot determine a cause, establish health safety, prove a waterproofing system works or authorise remediation.
