## Summary

Balustrade anchorage must connect to a structure designed for the required actions. WPC deck boards and decorative fascia should not be treated as the structural anchor by default.

## Practical method

Coordinate posts, brackets and waterproofing before laying boards. Show how movement of the walking surface is kept compatible with the fixed balustrade connection. For an illustrative balcony refurbishment, confirm the existing structural edge and fastener condition rather than assuming the old post position remains suitable. Keep inspection access where the design requires it. Guard height, loading and other compliance requirements belong to the project design; this article does not prescribe a universal detail.

## Planning and verification

Compare complete systems for the stated use, including supporting structure, connections, drainage and maintenance access. Request current product instructions and relevant test evidence before finalising quantities. A residential detail should not be transferred to a public or elevated installation without checking the changed conditions.

## Handover and maintenance

Record the selected profile, batch, approved drawings and maintenance owner. Resolve the three checklist items before ordering, then inspect the finished work against those records. Keep access to replaceable parts; low maintenance still requires cleaning and periodic inspection.

## Balustrade posts beside WPC decking — What should be confirmed before ordering?

Balustrade anchorage must connect to a structure designed for the required actions. WPC deck boards and decorative fascia should not be treated as the structural anchor by default. Confirm the three project checks below with the supplier and the responsible designer. A sample establishes appearance, not approval of the complete installation.
