At a glance
A single-board repair starts by identifying the original profile and fixing system. Replacing the visible board without resolving the cause can repeat the failure.
Key points
- Failure cause
- Compatible replacement
- Approved removal sequence
Practical method #
Check neighbouring boards, joist condition, movement gaps and the event that caused the damage. Obtain the approved removal and refixing method; concealed clips may require a specific sequence. Compare the replacement's dimensions and appearance with the existing deck before cutting. An illustrative local repair may be possible without renewing the whole terrace, but structural damage or obsolete components can change that decision. Retain photographs and part codes, then check the finished repair for support, movement and safe walking transitions.
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.
