Start with the condition.
Understand the scope.
Identify the affected return grilles and the surface condition being addressed. Ask which removal, cleaning and refitting tasks are proposed and whether any fastening or finish damage needs separate attention. Keep ordinary grille dust distinct from evidence supporting a wider duct-cleaning proposal.
What may be involved
- return grille
- fasteners
- surface protection
- vacuum collection
Ask the provider to distinguish existing parts to inspect, proposed replacements, and tools, materials or reports included in the service. Confirm the work and exclusions after assessment; this list does not mean that every item will be supplied or replaced.
