Compare targeted repair and complete replacement only after identifying the cause and extent of damage. Replacing every board may not address a defective supporting structure.

Practical method #
Map serviceable and affected areas, then check whether compatible replacement components remain available. Cost investigation, access, disposal and reinstatement as well as boards and labour. For an illustrative courtyard, targeted repair may reduce disruption, while repeated failures caused by poor drainage may justify a wider redesign. Use the same evaluation period and realistic maintenance assumptions for both options. Do not convert warranty years into certain remaining life. Document what evidence would change the decision.
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.
