If your deck is unsafe, rotting or leaking, it may require structural remediation — not a patch job.

We deliver:

• Full deck rebuilds
• Rotten timber replacement
• Structural strengthening
• Balustrade upgrades
• Waterproofing improvements

Most deck projects range $8,000–$25,000+.

Ashburton's climate demands decks that are built to last. From soil conditions to drainage and sun exposure, Oncore ensures every deck is constructed using proven materials and best-practice building methods.

We build decks that are:

• Structurally sound and compliant
• Designed for longevity and safety

Where required, we can also manage council consent and compliance, giving you complete peace of mind.
