The practical answer
Sanding removes surface timber and coating. It is valuable when the deck is rough, grey, peeling, heavily scratched or uneven, but unnecessary sanding can remove timber that did not need to be removed.
Preparation should begin with identifying the current coating, checking fixings and deciding whether cleaning alone can create a suitable base.
What to check before choosing a treatment
- Whether the existing coating is penetrating, film forming, paint or unknown
- Whether timber is sound, dry and securely fixed
- How open sun, cover, gardens, pools and drainage affect different zones
- Whether the deck is residential, shared common property or commercially used
- What level of appearance, maintenance and downtime is realistic
When professional sanding is likely to be needed
Sanding is more likely when there are peeling coatings, severe greying, rough fibres, scratches, cupping, patchy colour or several incompatible layers. Cleaning and recoating may be enough when the existing finish is sound, compatible and only beginning to wear.
When repairs should come first
Soft boards, broken edges, loose fixings and damaged stair components should be addressed before final preparation. Hidden framing, support or compliance concerns fall outside cosmetic restoration and may need another suitably licensed contractor.
Gold Coast conditions to allow for
Sun, salt, humidity, storm rain, pool water, leaf litter and shade can all change the way a deck dries and wears. A beachside balcony, canal pool deck and shaded hinterland verandah should not be treated as though they are the same environment.

Frequently asked questions
Can this problem usually be restored?
It depends on whether the issue is limited to the surface or includes widespread rot, movement or structural failure. We inspect the deck before recommending cleaning, sanding, repairs, coating or replacement.
Can you quote this across the Gold Coast?
Yes. We cover waterfront, coastal, suburban, leafy and apartment locations from Coomera to Tweed Heads, east of Mount Tamborine.
What information helps with a quote?
The suburb, approximate size, photos, timber type if known, current coating, access and the result you want are useful. A site inspection may still be required.
