Deck and patio cleaning cost in Brisbane

By the WTD team · Updated June 2026

Deck and patio cleaning in Brisbane runs $80 to $250 for a clean-only and $250 to $350 or more for a timber deck cleaned, sanded and re-oiled, with most jobs around $180. The catch is technique - the cheapest-looking option, a hard fast blast, is often what damages the surface, especially on timber.

Quick answer — deck and patio cleaning cost in Brisbane

Here's where deck and patio cleaning lands in Brisbane in 2026, before we get into surfaces and why technique matters so much here.

Most jobs land around $180. The catch with this category is that the cheapest-looking option — blast it hard and fast — is often the one that damages the surface, especially on timber.

Timber decks: the low-pressure rule

A timber deck is the surface where technique matters most, and where a bad pressure-wash does lasting harm. Timber is soft relative to the water coming out of a pressure washer, so too much pressure raises and "furs" the grain, gouges lines into the boards, and can splinter softer timbers. Once a deck is furred, you can't un-fur it — it has to be sanded back.

The right way is a gentle clean: a wide fan tip, the nozzle kept at a safe distance, and consistent passes along the grain rather than blasting one spot. That lifts the grey weathering, grime and mildew without tearing the surface. A clean-only on a deck in reasonable shape sits at $80–$250 depending on size. It's not slow because it's hard — it's slow because it's careful, and that care is exactly what you're paying for.

Cleaning, then re-oiling

Cleaning a tired deck strips off the grey and the old, failing finish — which is great, but it also leaves bare, thirsty timber that needs protecting. That's why deck jobs are often quoted as clean, light sand and re-oil together, landing at $250–$350 or more for the full restoration.

Doing it in one go is far more cost-effective than separate visits, because the timber has to be clean and dry before oil goes on anyway. A fresh coat of decking oil restores the colour, protects against Brisbane's sun and summer storms, and slows the next round of greying. If you only clean and skip the oil on a weathered deck, you'll be back sooner than you'd like.

Paved patios, travertine and sandstone

Hard paving is more forgiving than timber, but natural stone has its own rules.

Concrete and clay pavers ($100–$300) clean up well, though the joints trap dirt and weed growth and the jointing sand can wash out under heavy pressure and need topping up.

Travertine, sandstone and other natural stone ($150–$350) are softer and usually sealed, so they need lower pressure and the right cleaning solution rather than a hard blast. Done wrong, high pressure pits the stone and strips the seal — and a stripped seal then needs replacing, which is a cost you created. A good operator treats sealed stone gently and tells you whether the seal needs renewing afterwards.

One thing that surprises people: a white, powdery residue appearing on pavers after cleaning is usually efflorescence — mineral salts drawn to the surface — not leftover dirt. It's common, it's treatable separately, and a good operator will identify it rather than just blasting harder.

What a cheap blast actually costs you

The reason to be picky here is simple: the damage from over-aggressive cleaning is permanent and expensive to undo. A furred deck needs sanding, sometimes board replacement. Pitted travertine can't be un-pitted. A stripped seal has to be re-laid. The few dollars "saved" by someone blasting it fast and hard can turn into a far bigger restoration bill — which is exactly why the careful, lower-pressure quote is usually the cheaper option over the life of the surface.

A real Brisbane example

Take a 20 m² spotted-gum deck in Paddington that's gone grey and a bit slippery, with mildew in the shaded corner near the fence. The owner's first instinct is a quick blast to bring back the colour.

Instead, the job is a low-pressure clean along the grain to lift the grey and the mildew, a light sand to knock back any raised grain, and a fresh coat of decking oil to protect it and restore the warm tone. Quoted as a package, it comes to $320 — versus an $120 "blast" that would have furred the boards and left bare timber to grey off again within months. The package costs more on the day and far less over the next few years.

Getting it quoted right

Tell the operator the surface — timber species if you know it, or "natural stone / travertine / pavers" — and whether you want protection (oil or seal) as well as cleaning. Send a photo of the worst area. The two questions that matter most: what pressure and technique will they use on a timber or sealed-stone surface, and is a re-oil or reseal included or extra? Get clear answers to those and you'll get a deck or patio that looks restored and stays that way, rather than one that's clean today and damaged for good.

Frequently asked questions

How much does it cost to clean a deck or patio in Brisbane?

A clean-only on a timber deck in reasonable shape runs $80 to $250 depending on size, with most jobs around $180. A full restoration - clean, light sand and re-oil - sits at $250 to $350 or more. Paved patios run $100 to $300, and travertine or natural stone $150 to $350.

Can pressure washing damage a timber deck?

Yes, and the damage is lasting. Timber is soft relative to the water from a pressure washer, so too much pressure raises and furs the grain, gouges the boards and can splinter softer timbers. Once furred, a deck has to be sanded back. The right method is a gentle clean with a wide fan tip, the nozzle kept at distance, and passes along the grain.

Should I re-oil my deck after cleaning?

On a weathered deck, yes. Cleaning strips off the grey and the old finish but leaves bare, thirsty timber that needs protecting. Deck jobs are often quoted as clean, light sand and re-oil together ($250 to $350+) because the timber has to be clean and dry before oil goes on - doing it in one visit is far cheaper than separate trips, and a fresh coat slows the next round of greying.

What is the white residue on my pavers after cleaning?

A white, powdery residue appearing on pavers after cleaning is usually efflorescence - mineral salts drawn to the surface - not leftover dirt. It is common, it is treatable separately, and a good operator will identify it rather than just blasting harder.

Do travertine and sandstone need special cleaning?

Yes. Travertine, sandstone and other natural stone are softer and usually sealed, so they need lower pressure and the right cleaning solution rather than a hard blast. High pressure can pit the stone and strip the seal, and a stripped seal then needs replacing. A good operator cleans sealed stone gently and tells you whether the seal needs renewing afterwards.
