A pool deck is one of those projects where the price range is all over the place. Some Sydney homeowners are quoted numbers that look like a full kitchen renovation, others get a price that seems too good to be true. The reason is simple: a pool deck isn’t a standard deck. It lives in the wettest, most chemically challenging spot in your backyard, and half a dozen site-specific factors can push the final figure up or down by thousands.
Rather than collecting three quotes before you even know roughly what you should be paying, it’s far quicker to start with a guide price of your own. Our deck cost calculator lets you design your pool deck in 3D and get an instant guide price, with no site visit needed — so you can size up options before you talk to anyone.
In this guide, we’ll break down what a pool deck actually costs in Sydney, why it’s priced differently from a regular backyard deck, and the factors that genuinely move the number.
Why a Pool Deck Costs More Than a Standard Deck
A deck beside a swimming pool works harder than any other timber or composite structure on your property. It gets splashed daily, sits in permanently humid air, and copes with chlorine or salt water on its surface year-round. That changes both the materials you should use and the way the deck needs to be built.
Non-slip performance is not optional near a pool. Bare feet, wet surfaces and children running around mean the boards you choose need genuine slip resistance — which usually means a grooved or textured composite product or a hardwood installed with the right finish. Poorly chosen boards that turn into an ice rink when wet often end up being replaced within a few years, which is the most expensive pricing mistake of all.
There’s also the sun. A pool area is usually wide open, with no shade from the house, so boards are exposed to full UV all summer. Cheap products fade, cup and splinter under that kind of exposure. This is why pool-grade composite — materials specifically designed for high UV and constant moisture — is the most common choice around Sydney pools, and why it sits at $550 per square metre against $440 per square metre for standard hardwood decking.
What You Should Budget Per Square Metre
As a Sydney guide price, expect:
Composite and pool-grade decking builds come in at around $550 per square metre, including the frame, boards, fixings and labour. Hardwood decking builds run at approximately $440 per square metre. And if you already have a structurally sound deck around your pool that’s simply tired and grey, a full restoration — pressure cleaning, sanding and re-oiling — is around $153 per square metre, a fraction of the cost of a rebuild.
Put simply, a 20 square metre pool surround will land somewhere different to a 40 square metre entertaining deck that wraps around the pool and up to the back door. A smaller pool surround of 15–20 square metres might come in around $8,000–11,000, while a larger 35–40 square metre composite deck with all the trimmings is closer to $20,000+. These are guide prices, not fixed quotes — the exact figure depends on the factors below.
One thing worth noting: because pool decks are usually built at ground level over concrete or pavers rather than raised on a large subframe, they’re often cheaper per square metre than an elevated rear deck — but only when the existing surface is suitable. Which brings us to the factors that matter.
Five Factors That Change the Price of Your Pool Deck
1. Size and shape. A rectangular pool surround is the cheapest layout per square metre. A curved pool edge, an L-shaped deck or a wraparound design means more cutting, more wastage and more labour hours. The simpler the shape, the further each square metre of material goes.
2. The boards you choose. This is the biggest single decision. Composite designed for pool areas costs more upfront than hardwood but won’t splinter, resists fading, and never needs annual oiling. Hardwood is cheaper to install and looks beautiful, but around a pool it needs ongoing maintenance. Over ten years, the maintenance gap narrows the real difference considerably.
3. What’s underneath. Building over an existing, well-drained concrete slab or paved area is relatively straightforward. If the ground is poor, sloping or needs new footings and drainage work, the site preparation adds to the cost before a single board goes down.
4. Pool fencing and council requirements. In NSW, any deck adjacent to a swimming pool has to work with your pool fence and often needs a complying barrier, non-climbable zones and the right gate hardware. If the deck changes the pool surroundings, council compliance requirements apply. The fencing itself is usually a separate line, but it’s a cost you must budget for alongside the deck.
5. Height and access. A deck that steps down from the house to the pool, or needs stairs, custom edge trims and multiple levels, costs more than a single flat unit. Restricted side access for materials also adds labour time on many Sydney blocks.
Restore or Replace?
Not every tired pool deck needs demolishing. If the frame is solid, boards are fixable and the structure drains properly, a restoration at roughly $153 per square metre can add years of life while you plan a future rebuild. The honest test is the frame: if joists are rotting or the deck moves underfoot, restoration is money down the drain and a rebuild is the better investment. If it’s only the surface that looks tired, you can enjoy the restored finish and revisit a composite upgrade down the track.
