Get a named handover from the people resolving the water and material condition before scheduling closure.
Separate the water problem from reinstatement
Health Canada recommends addressing the moisture source and warns that painting over mould does not resolve it. Keep leak repair, assessment of affected materials and drywall reinstatement as separate responsibilities. A cosmetic repair booking is not a mould assessment or a decision that the wall is ready to close.

Prepare a closure-readiness record
| Record | Who should supply or confirm it |
|---|---|
| What caused the leak and what was repaired | The trade or professional responsible for the source. |
| Which materials and areas were assessed | The person responsible for moisture and material assessment. |
| What was removed, retained or treated | The contractor responsible for that work and its records. |
| What establishes readiness for closure | The appropriate assessor or project lead, with any applicable measurements or reports. |
| Outstanding checks or approvals | The permit holder, project lead or responsible professional, as applicable. |
| Who authorises reinstatement | A named decision maker communicating the accepted scope to the drywaller. |
Ask what the evidence covers and what remains uncertain. A receipt for a plumbing repair does not, by itself, describe the condition of every affected wall material. Keep the source-repair record and the closure decision together.
A dry-looking face is not the whole assessment
Health Canada notes that mould can be hidden behind walls or ceilings and recommends professional help when moisture sources or corrective actions are unclear. If the incident history raises a concealed-damage concern, ask an appropriately experienced professional to determine the next step rather than opening material yourself.

- Share the dates and known source of the incident.
- Identify which rooms and surfaces were affected or opened.
- Provide the relevant investigation, removal and drying records.
- Mark areas that have not yet been assessed.
- Identify insurer, strata or property-manager decisions that affect the scope.
Then define what is being put back
Once the responsible people have confirmed the next stage, separate reinstatement from any wider upgrade. Identify the board and assembly requirements, insulation or other affected layers, access openings, trim, texture and decorating boundary. Name who supplies each part.
Richmond: retain both the water handover and the applicable inspection result
Richmond’s portal provides issued-permit inspection results.

Before reinstatement, collect the leak-source repair and moisture-assessment handover as well as any applicable permit result. The portal record does not, by itself, establish that every affected material has been assessed for moisture. Name the person accepting readiness for the particular wall or ceiling area.
- Mark the extent assessed for moisture and any area still excluded or inaccessible.
- Ask the project lead whether closure would conceal an outstanding condition.
- Keep original reinstatement distinct from a requested change in board, texture or decorating scope.
A few practical questions.
Can a water stain tell me the wall is ready to close?
No. Record the incident and obtain the appropriate assessment and handover for the affected area. The appearance of the finished face does not establish concealed material condition or confirm that the water source is resolved.
Does the drywaller decide which wet materials can remain?
Agree that responsibility explicitly. The project needs a named person with the appropriate scope and expertise to assess the affected materials and confirm closure readiness. Do not assume a cosmetic repair estimate includes that assessment.
