Deck Restoration Cost Melbourne: 2026 Guide

A timber deck in Melbourne takes more punishment than almost any other surface on a property. Full summer UV, winter rain, and the daily expansion and contraction that comes with both. Left alone, the timber goes silver-grey, the surface fibres lift, and what was a nice deck becomes something you avoid walking on barefoot.

Restoration brings it back. This guide covers what the work involves, what drives the price, and how to judge whether your deck needs restoring or replacing.

What deck restoration actually involves

Five stages, and the finish everyone focuses on is the last and quickest.

Inspection. Checking boards, joists, bearers and fixings for rot, movement and structural problems. This is the stage that determines whether restoration is even the right answer.
Cleaning. Stripping back dirt, mould, algae and any failed previous coating, usually with a timber cleaner and controlled pressure washing.
Sanding. Taking off the grey, weathered surface layer and the lifted fibres, and levelling any cupping. This is what makes the difference between a deck that looks restored and one that looks washed.
Repairs. Replacing damaged boards, punching and filling proud fixings, re-screwing loose boards, treating any rot found.
Finishing. Two or more coats of oil, stain or a decking paint, applied once the timber has dried out properly.

That drying step matters more than people expect. Timber washed on Monday is not ready to be oiled on Tuesday in a Melbourne winter. Coating damp timber traps the moisture underneath and the finish fails early.

Common deck problems in Melbourne

What you see	What it means
Silver-grey surface	UV has broken down the surface fibres. Normal, and what sanding removes
Rough, splintering boards	Lifted grain from weathering. Needs sanding, not just recoating
Black spotting	Mould and algae, usually in shaded or poorly drained areas
Cupped or bowed boards	Moisture imbalance between the top and underside of the board
Nails or screws standing proud	Timber movement over time. Must be punched before sanding
Soft, spongy timber	Rot. Needs cutting out and replacing, not coating
Finish peeling in sheets	A film-forming product applied over damp or unprepared timber
Boards moving underfoot	A fixing or substructure issue, which is a safety matter

The last two are the ones worth acting on promptly. Peeling finish means the next coat will fail the same way unless the surface is stripped properly, and movement underfoot usually means something structural rather than cosmetic.

Restore or replace?

Restoration makes sense when the substructure is sound and the boards are structurally fine, even if they look terrible. Weathered, grey, splintery timber almost always comes back well.

Replacement starts to make sense when a significant number of boards are rotten or split through, when the joists or bearers have deteriorated, or when previous repairs have left a patchwork of different timbers that will never look even.

A contractor who inspects the substructure rather than just the surface is giving you the information you need to make that call. One who quotes a sand-and-oil on a deck with soft joists is selling you a finish on a problem.

What drives the cost

Size and layout. Price follows area, but a deck with stairs, balustrades, built-in seating and tight corners is far slower per square metre than an open rectangle.
Condition. A deck that needs a light sand and recoat is a different job from one needing heavy sanding, board replacement and rot treatment.
Timber species. Hardwoods sand differently from treated pine and take finishes differently.
Existing finish. Removing an old film-forming paint or a failed stain is slow work. Bare or oiled timber is much faster to prepare.
Board replacement. The number of boards and whether matching timber is readily available.
Access. Elevated decks, decks over sloping ground and anything needing scaffolding add setup cost.
Finish chosen. Oils, stains and decking paints differ in both material cost and number of coats.

As with roofs, condition is the variable that separates quotes. Nobody can price this accurately without walking the deck.

Choosing the finish

The three options behave very differently, and the choice affects both the look and how often you will be back out there with a brush.

Decking oil soaks into the timber rather than forming a film on top. It keeps the natural grain visible, it cannot peel because there is no film to lift, and reapplication is straightforward: clean and recoat. The trade-off is frequency, usually every 12 to 18 months in a Melbourne climate on an exposed deck.

Stain sits somewhere between oil and paint. It lasts longer than oil, adds colour while keeping some grain visible, and suits decks where you want a more uniform appearance.

Decking paint gives the most colour control and the longest recoat interval, but it is a film on a horizontal surface that gets walked on, rained on and heated. When it eventually fails it peels, and stripping peeling paint off decking boards is a genuinely unpleasant job.

For most Melbourne residential decks, oil or stain is the sensible default. Our guide to deck oil, stain or paint works through the decision in more detail.

Timing the work

Timber needs to be dry, and the finish needs reasonable temperatures to cure, which rules out much of a Melbourne winter.

Spring and early autumn are ideal: dry enough, mild enough, and the deck is ready for the season you actually use it in.
Summer works, but avoid oiling in the full afternoon heat, when the finish flashes off before it can penetrate.
Winter is the hardest. Timber stays damp for days after washing and recoat times stretch out.

If you are aiming to have the deck ready for summer entertaining, book the work in spring rather than November. See getting your deck ready for summer.

Allow two to four days for a typical residential deck, most of which is drying time between stages rather than active work.

Keeping it that way

The single biggest factor in how often you need a full restoration is what you do in between.

Sweep regularly, particularly leaf litter in autumn, which traps moisture and stains the timber
Wash the deck once or twice a year with a timber-safe cleaner
Recoat with oil before the finish has fully worn away, not after. Topping up an oiled deck is simple; restoring a bare, greyed one is not
Keep pot plants on feet rather than flat on the boards, and move them occasionally
Clear the gaps between boards so water drains instead of sitting

A deck maintained this way may never need another full sand. A deck left to go fully grey needs the whole process again every few years.

Frequently asked questions

How much does deck restoration cost in Melbourne? It depends on size, layout, timber condition, how much board replacement is needed and what finish you choose. A light sand and recoat sits at one end; heavy sanding with rot repair and board replacement at the other. Get it quoted after an inspection, not over the phone.

How often should a deck be restored? A full sand and refinish every few years on an exposed deck, though regular cleaning and topping up the oil can extend that considerably. Sheltered decks go much longer.

Can a grey, weathered deck be brought back? Usually yes. Grey is surface-level UV damage, and sanding removes it to reveal sound timber underneath. Only soft or rotten boards need replacing.

Is pressure washing enough on its own? No. Washing cleans the surface but leaves the lifted, weathered fibres in place, so the deck still feels rough and the finish does not last. Sanding is what makes the difference.

Can you restore a deck in winter? It is possible but not ideal. Timber stays damp far longer, drying times between stages stretch out, and the finish cures slowly. Spring and autumn give a better result.

Should I oil or paint my deck? For most residential decks, oil or stain. Paint forms a film on a surface that is walked on and weathered, and when it fails it peels, which is a difficult thing to put right.
