Discuss nearby doors, plants and occupied spaces before sanding. Appropriate containment and collection depend on the site and accepted material. This ordinary preparation service does not include hazardous dust remediation or work on a coating whose safety has not been established.
Show screws or nails sitting above the surface. Suitable ordinary fixing preparation may be needed before sanding can proceed. Damaged or unsupported boards need review, and simply driving fixings deeper should not be assumed to resolve deterioration beneath the deck surface.
If the coating history or material condition raises a hazardous-material concern, ordinary sanding should not proceed on an assumption. Share existing product records where available. Specialist testing or removal is outside the scope and must not be replaced by a disclaimer after disturbance.
Prepare and sand accepted sound boards with appropriate abrasive stages and dust control, within the agreed accessible area. Scope limits: Sound ordinary accessible boards only. No structural restoration, rot concealment, hazardous coating removal, asbestos or specialist dust remediation.
