South Sydney's Trusted Deck Restoration Specialists

A deck gone grey and splintered can look well past saving, yet it almost always holds far more life than you would think. Strip back the weathered top layer and the dense hardwood underneath is usually still sound, worth restoring rather than tearing out. Fierce sun, salt air and rain wear the colour and dry the boards, but a thorough sand and refinish reverses it for a fraction of the cost of rebuilding.

Transform Floors handles the full deck restoration, from the first wash through to the last coat. We assess the boards, sand back the grey and failed finish, repair what needs it, then refinish the wood to protect it. It is one professional team handling the whole job, from start to finish.

Decks are our trade, not a sideline. Our highly skilled team sands, repairs and oils outdoor wood every week across Sutherland Shire and the St George area, the same crew behind our floor sanding and polishing, and work we have done for over 25 years.

Signs Your Deck Needs Sanding and Refinishing

Timber gives you plenty of warning before it fails. If your deck shows any of these signs, it is time for a sand and refinish before the damage runs deeper and repairs get harder.

Grey, Weathered Timber

UV breaks down the surface fibres and leaves a dull grey. That greyed wood blocks the coat from soaking in, so we must sand it back to fresh wood first.

Mould, Algae and Dirt

Shade and humidity let mould, algae and grime build up on the boards. A proper wash and sand clears it and gives the finish a sound base to grip.

Cracked or Splintered Boards

Seasonal movement dries and splits the timber, raising splinters and the odd nick that make the deck unsafe for bare feet. Sanding smooths the rough boards and worn boards are replaced.

Raised Nails and Loose Fixings

As boards move, nails and screws lift and fixings job loose. These are trip hazards and water entry points, so we punch them down or replace them properly before sanding.

Peeling Paint or Failed Coatings

Old paint, varnish and worn coatings start peeling and flaking as they age. The deck has to be stripped and sanded back to clear timber, not given another coat over the top.

Rot and Structural Damage

Trapped moisture rots joists, bearers and posts, especially on older or ground-level decks. We check the structure with every deck sanding job and address any wood rot we find.

See the Difference a Restored Deck Makes

A sanded and freshly oiled deck looks great, close to new. The grain comes back, the colour deepens and the greyed, splintered surface is gone. It is the same wood you already have, restored and protected rather than ripped up and replaced, so you can enjoy the space again.

Deck Cleaning & Preparation

Every job starts with a deep wash. We use a deck cleaner to lift dirt, mould and grime, then let the wood dry fully so the sanding and finish take evenly.

Board Repair & Replacement

Rotted or split boards are replaced with matching timber and quality materials, and loose fixings are secured with stainless steel screws. We sort posts, railings and steps so the rest of the deck is sound.

Machine Sanding & Coating Removal

The heavy work is done with a belt sander along the boards, backed by orbital sanders for a smooth result. We sand this back, stripping old paint, coat and grey wood to a bare base.

Edge, Stair & Detail Sanding

Machines cannot reach every part of a deck, so we sand those spots by hand. We hand sand the edges, corners, posts and stairs, and use hand tools and detail work to ensure the finish is even into the tight spots.

Deck Oiling & Staining

Once the boards are bare and clear, we apply quality penetrating decking oil or a semi-transparent stain. Oil keeps a natural look, while stain adds UV protection and colour in a choice of colours.

Sealing & Maintenance Coats

For decks in good shape, a light screen sand and a fresh finishing coat keeps them protected. We can set up a simple, easy cycle to maintain the timber, so your deck never falls back to bare grey.

Decking Oil vs Stain vs Paint

Which Finish Suits Your Deck?

The sanding brings every finish back to the same starting point. What you put on top changes the look, the protection and how often the deck needs a recoat. Here is how the three main options compare.

Finish Options
Look
Protection
Upkeep / Longevity
Penetrating Deck Oil

Natural, matte and true to the boards

Soaks in to protect from moisture and UV

Re-oil every 12 to 18 months

Semi-Transparent Stain

Adds a choice of colours while the grain shows through

Stronger UV resistance and colour hold

Recoat every few years

Solid Paint

A full, opaque finish over the boards

Seals the surface but hides the boards

Peels in time and needs stripping to redo

*On most South Sydney hardwood decks, a penetrating coat is the surest way to protect the boards and keep a natural look.

Not Sure What Your Deck Needs?

Some decks need a full restoration, others just a clean and a fresh coat. On a free on-site visit, we look over the timber, sand a test patch, check the structure and recommend the right services and best way forward. We are happy to take a look.

How Much Does Deck Sanding Cost?

Deck sanding is usually priced per square metre, so the size and state of your deck set the cost. A basic sand and oil sits at the lower end. A full restoration with cleaning, repairs and several coats will cost more per metre.

Condition and species both matter. Dense hardwoods like Spotted Gum require more sanding than Merbau or pine, and a neglected deck with rot, board replacement or multi-level access is a bigger job. Balustrades, posts and stairs add time as well.

As a rough guide, a typical 20 to 25 square metre deck restoration in the South Sydney area often falls between $1,000 and $1,900. We measure on site and give you a fixed price in writing before any work starts, and most jobs finish in a day or two.

Our Deck Sanding & Refinishing Process

A deck that lasts starts with preparation, not the first pass of the sander. We never skip prep to save a minute, and follow the same steps on every job, so the finish holds up to years of weather. Each stage requires care and attention to detail.

1. Inspection and Assessment

We check the boards species, the coatings and the structure, including joists, bearers and posts. This tells us what needs fixing and how much sanding the deck will take.

2. Cleaning and Preparation

The deck is cleaned of dirt, mould and old grime, then left to cure for two to three days. A deck brightener can be used to even the colour before we sand, which also cuts drying time.

3. Repair and Fixings

Damaged boards are replaced with matching stock and quality materials, and raised nails are countersunk to protect the sandpaper. We secure loose posts, railings and steps so the deck is safe underfoot.

4. Sanding Back to Bare Timber

We sand with coarse grit to strip the grey and old coatings, then a finishing pass with finer sandpaper for a smooth result. Belt sanders handle the open boards, with detail tools and power tools for the edges.

5. Oiling or Staining

Once the deck is vacuumed clean, we apply two to three coats of decking oil or stain, working with the grain to ensure an even finish. Each coat dries before the next goes on.

6. Curing and Clean-Up

We let the finish cure before moving furniture back, and we leave the site clean, neat and looking great. Once the job is completed, you get care advice so the deck stays protected for as long as possible.

Decking Timbers We Restore

Every deck weathers and drinks finish differently. We restore all the common decking species, adjusting the sanding and the finish to suit whatever your deck is built from.

Merbau

Merbau is the most common deck deck in South Sydney. It bleeds tannin when cleaned, so we manage the run-off and let it settle, then re-coat to restore the deep red-brown colour.

Spotted Gum

Spotted Gum is dense and hard-wearing, which means it requires that we sand harder to strip a weathered surface. The reward is a great, beautiful grain and years of durability once oiled.

Blackbutt

Blackbutt gives a paler, even tone that suits a natural finish finish. It sands cleanly and takes coats evenly, holding its colours well against the harsh Sydney weather.

Jarrah

Jarrah carries a rich red warmth worth bringing back. Once the grey is sanded off, a quality finish or stain lifts the colour and protects the deck for years.

Treated Pine

Treated pine is softer and common on older decks. It needs a gentler, careful sand so the surface is not gouged, and it takes stain well for added colour and protection.

Hardwood Decking & Merbau Blends

Mixed hardwood decks and blended boards are common in South Sydney. We match any replaced boards to the surrounding wood and finish the whole deck as one even surface.

Our Deck Sanding Workmanship & Guarantees

We take pride in tidy, professional work and a finish that lasts. Every deck sanding job is quoted clearly and backed by our workmanship guarantee.

Dust Extraction and Clean Work

Our sanders run with dust extraction and professional equipment, so there is far less mess across your garden and outdoor area. We clean down thoroughly before any finish goes on.

Highly Skilled Deck Team

Decks require specialist care, not a bit of weekend sanding. Our highly skilled team has taken years to learn how each timber behaves, and excellent work on every deck is the standard.

Fixed Quotes and Fair Pricing

You get a fixed price in writing before we start, covering the clean, the sanding, any board fixes and the coats applied. There are no hidden extras once the job is under way.

Honest Advice From the Start

If your deck only needs a clean and a recoat, we tell you that. We recommend the work that suits your deck and budget, not the biggest job we can sell.

Unsure If Your Deck Can Be Saved?

Most decks can be brought back, even ones that look far gone. On a free on-site visit, we check the boards and structure and tell you honestly whether a sand and refinish will restore it.

Deck Sanding & Refinishing FAQs

How often should a deck be sanded and re-oiled?

Most South Sydney decks need re-oiling every 12 to 18 months, and we recommend a full sand every three to five years. Exposed and coastal decks weather faster, so they come up more often. A quick annual wash and light sand helps the finish last longer between sands.

Can a grey, weathered deck really be restored?

Almost always. The grey is only a thin, oxidised layer on the surface. Once we sand it back to fresh timber and refinish it, even a badly weathered deck can look great and be protected for years.

Do you repair boards and fix structural problems too?

Yes. Loose fixings, raised nails, split boards and rot are all part of the job. We replace damaged boards with matching timber, sort posts, railings and steps, and address any structural issues before sanding.

What is the difference between decking oil and stain?

Decking oil soaks in for a natural look and deep protection, which suits most South Sydney hardwoods. Stain adds more colour and UV resistance in a wider range of colours. We recommend the right one for your timber and how exposed the deck is.

How long does deck sanding and refinishing take?

Most decks take one to three days, depending on size, condition and weather. Cleaning, drying, sanding and two or three coats of oil each need time, and the timber has to be ready before we sand. Rain can stretch the job out.

How much does deck sanding cost in South Sydney?

It is usually charged per square metre. A typical 20 to 25 square metre deck restoration in South Sydney often runs between $1,000 and $1,900, though the cost depends on timber, condition and board work. We quote a fixed price on site.

Do I need to remove furniture and planters first?

It helps if you can clear the deck of furniture, pots and garden items before we arrive. Anything left we move carefully, but a clear deck lets us sand and oil the whole surface in one go.

Will sanding create a lot of dust and mess?

Far less than you might expect. Our sanders run with dust extraction, and we clean down as we go, so there is minimal dust across your house and garden. The area is left tidy at the end.

Can you sand and oil a painted deck?

Yes. A painted deck takes more work, since the paint has to be stripped and sanded off first. We use a paint stripper on old paint or varnish, and coarse grit, and we sand back to clean timber, then re-coat or stain from there.

What products do you use on decks?

We use quality, UV-stable decking oils and stains built to a high quality for Australian conditions, from brands such as Intergrain and Cabot's. The right product depends on your timber, the colours you want and how much weather the deck gets.

Is deck sanding something I can do myself?

You can, but a deck is more difficult than it looks. The grit sequence, keeping the sander flat, managing dust and getting an even finish all take practice, and mistakes show. Most people find a professional result is worth it for a large deck.

How do I keep my deck looking good after sanding?

Clean it a few times a year, hose off leaves and dirt, sand any rough spots, and re-oil every 12 to 18 months to maintain the colour. A light maintenance coat is easy and keeps the deck from greying again. We are happy to set up a simple schedule.
