Deck Restoration Scope Checklist: Preparation, Repairs and Finish

“Restore the deck” can mean very different work. One deck may need sound boards prepared and recoated; another has loose fixings, failing coating or timber that needs repair before any finishing. A useful scope explains what is known, what still requires inspection and where surface restoration ends. It should not imply that sanding or oiling makes an unsafe structure safe.

This checklist helps a Brisbane homeowner read a proposed scope. It is not a diagnosis for a particular deck. For the wider choice between surface restoration, repair and replacement, see our deck repair-or-rebuild guide.

1. What is the condition of the boards and structure?

Record which boards are sound, split, soft or moving, and whether any fixings are loose or protruding. Grey colour and a rough surface are not the same thing as decay or a damaged frame. If joists, posts, balustrades or stairs raise safety concerns, an appropriately qualified trade needs to assess that work. A coating proposal should not silently absorb structural work it does not include.

Ask which surfaces were inspected and which were inaccessible. If the underside could not be seen, say so in the scope instead of treating hidden framing as verified. Note whether a board repair is proposed before surface preparation, and whether a new board may finish a different colour from the weathered original.

2. What existing finish is present—and what must come off?

Peeling film, patchy colour, exposed traffic lanes and tackiness can point to different preparation needs. A photograph alone cannot identify the old product or establish why it failed. Intergrain’s trade guidance on coating failures identifies weathered fibres, contamination, moisture, previous-coating compatibility and application conditions as separate factors. Its guidance for worn, patchy coatings explains why applying a fresh finish over an uneven old base can be problematic. Those sources are diagnostic context, not proof that a particular product or cause is present on your deck.

The written scope should say whether the old layer will be removed, cleaned, mechanically prepared or tested in a sample area. If the old product is unknown, make that uncertainty explicit. Our complete deck-restoration guide explains the broader restoration process.

3. Which preparation method suits the boards?

Different boards and fixings can call for different preparation. The proposed scope should identify the method and its limits: how high fixings, edges, grooves, damaged areas and adjoining surfaces will be handled. Quality Floors’ Blitz wire-brush article describes one available method; it should not be assumed suitable for every deck. Ask what the selected process is meant to remove and what appearance it will leave.

Preparation also includes access and protection. Confirm furniture, pots, built-in features, nearby walls and plants, and whether weather could interrupt coating. A deck with sunny and shaded zones may dry and weather differently; the coating plan needs to account for the manufacturer’s conditions, not a blanket promise about timing.

4. What repairs are included, and who performs them?

List each board or fixing repair separately from sanding and coating. If a board is replaced, ask how its size, timber and profile will be matched and what difference in colour may remain. If structural repairs are needed, identify the responsible trade and the point at which coating work can resume. An honest proposal can leave some sound, aged timber visible; it should not promise that every imperfection will disappear.

5. Which finish system and maintenance plan are proposed?

Ask for the manufacturer, product, colour or tint, the preparation it requires, and how the choice suits the timber and exposure. A sample on the actual boards is more informative than a freshly wet photograph of another deck. The dry appearance can differ from the initial wet look. Our deck colour guide explains that choice; how often to oil a Queensland deck explains why maintenance is based on exposure and condition rather than a universal calendar.

The care and return-to-use instructions should come from the product actually applied and the weather during the work. Avoid promises that a coating “never peels” or lasts a fixed number of years regardless of exposure.

6. What should the final written scope contain?

Before work starts, confirm the inspected areas, included boards and repairs, preparation method, product system, exclusions, weather contingency and how unexpected defects will be handled. At handover, retain the product details and care instructions. A finished photograph can demonstrate appearance at that moment; it does not prove long-term durability or structural safety.
