MEL ONEStart with the part that has actually failed
Raised grain, splinters, loose fasteners and localised rot can affect boards without proving that the frame has failed. Inspect joists, bearers, posts, connections and the timber where it meets the house. Soft timber, persistent movement, decay around fixings or poor drainage are reasons to investigate beyond a surface re-oil.
Allow for Adelaide exposure
Sun, rain and coastal air affect decks differently. Record orientation, shade, moisture paths, proximity to the coast and whether leaf litter or planter boxes hold moisture. This gives a more useful basis for material, fixing and finishing decisions than a generic lifespan claim.
Prepare a quote-ready scope
Provide wide and close-up photos, approximate dimensions, access constraints, stairs, balustrades and any built-in elements. Separate demolition, frame assessment, board replacement, handrails, finishing and waste removal so the quote is clear about fixed work and site-dependent findings.
Choose the next step on evidence
A sound frame may suit selective board replacement and maintenance. Compromised load-bearing members, post bases or connections may call for a more complete repair or replacement. Discuss approvals, boundary issues and safety requirements with the relevant professional before structural changes.
