Splintering boards and screws lifting in an entertaining area need board and fixing checks. Keep people off unstable areas. A surface oil does not repair loose connections or hidden decay, even when only a small patch is visibly affected.
Deck structure and safety
Movement, deteriorated posts or beams, loose balustrades and problems at the house connection can be structural concerns. Visible boards do not reveal the full support condition. Appropriate assessment is needed before loading or repairing an unstable deck.
Repair before coating
Damaged boards and fixings should be assessed before oiling so preparation does not conceal an unresolved defect. Coating suitability depends on timber and existing finish. Agree repair, cleaning, preparation and the selected finish as distinct work items.
