One person should confirm the opening is ready, the repair boundary is final and the required details are available.
Make an opening-by-opening inventory
| Record | Example detail · illustrative only |
|---|---|
| Location | Kitchen, wall behind the sink, opening A. |
| Approximate dimensions | About 40 × 60 cm; final repair boundary not yet assessed. |
| Reason for access | Plumbing work; ask the plumber to confirm completion. |
| Other work expected | Second trade visit or additional opening still possible. |
| Existing finish | Painted smooth wall meeting tile and cabinet trim. |
| Special detail or uncertainty | Existing assembly unknown; ask the project lead what information is needed. |
Photograph the whole surface and the visible opening from a safe position. Do not reach into it, remove additional material or disturb services to improve the record. Mark provisional dimensions as provisional.
Get the release to close before booking the repair
- Ask the responsible trade whether its work in that opening is complete.
- Ask the permit holder or project lead which checks apply and whether they are complete.
- Confirm whether another trade needs the opening before it is repaired.
- Identify any access that must remain, with the appropriate detail and approval.
- Name the person authorising closure and communicate that decision to the drywaller.
Collect the completed trade checks and any applicable inspection result before the closure decision. A trade invoice or an inspection request is not the same record as an accepted result. Use the local section below to find the relevant authority; the required checks depend on the actual permitted work.
Restore the required detail, not just the visible face
Ask whether the repair affects a specified fire-resistance-rated assembly. UL’s guidance makes clear that the rating belongs to the complete assembly and its specified components. Have the responsible professional identify the applicable repair detail before the opening is treated as a generic patch.

- Obtain relevant drawings, existing assembly information and accepted repair details.
- Identify who restores any affected insulation, membranes or other layers.
- Confirm any required access arrangement with the responsible trade and project lead.
- Record who checks the completed work before the next layer or trade proceeds.
Price the finishing and decorating boundary
The trade’s opening, the drywaller’s repair area and the painter’s work area may be different. Ask the estimate to show all three. Identify adjoining tile, cabinetry, trim and corners that constrain the handover.
| Boundary | Question before accepting the estimate |
|---|---|
| Opening to repair | Is the opening final, and who accepts the assessed repair extent? |
| Repair to existing wall | Where does finishing extend and how is an existing texture addressed? |
| Drywall to decoration | Who primes, who paints, and which complete surfaces are included? |
| Completed repair to later work | Who protects the surface and handles damage from a return visit? |
Delta: close each service opening after the relevant layers are released
Delta’s guide places applicable air or vapour-barrier review before drywall installation.

For a service opening through an affected assembly, have the lead identify how the barrier and other layers are restored and checked. A service invoice does not describe the whole repair. Ask the responsible trade about continuing access before agreeing a permanent closure.
- Use one opening label for the service completion, applicable results and surface estimate.
- Name who restores each affected layer and who authorises the next one.
- Keep the physical patch, finish blend and paint boundary separately priced and accepted.
A few practical questions.
Can I get the drywall estimate while the other trade is still working?
You can describe the likely work and flag what is provisional. Ask whether the estimate is conditional on the final opening, required checks and assessed repair detail. Confirm those points before accepting a closure date.
Should every opening become an access panel?
Ask the responsible trade and project lead whether ongoing access is needed and what detail is appropriate. Do not substitute an access panel or close an opening permanently without resolving the project’s requirements.
