Composite Decking Cost in Perth — Pioneer, MoistureShield and Eva-Last | Endure Decks

At Endure, these are the composite boards we work with — what they cost supply-and-installed to our spec, why a smaller deck is the sweet spot for Pioneer, and why composite in full sun is hot like artificial lawn.

Endure Decks — Perth deck builders · Updated 28 May 2026

These are supply + install rates for an Endure-spec'd deck — boards, properly built subframe, design, prelims and the 20-Year Standard build method. They aren't generic market rates, and they don't track what a less-involved installer charges. The numbers below are what we deliver, all-in.

Expect $540–$760 per square metre installed inc GST, depending on the board. Across a standard 30–45 m² composite build that lands at roughly $25,000 to $40,000. A 22 m² composite deck on a clean site can come in around $23,000 inc GST; a 36 m² composite deck with stairs sits anywhere from $28,000 to $39,000 depending on which board you specify. Both ends of those figures come from actual Endure jobs.

Composite supply cost swings hard across the boards on market — the difference between the accessible composite and the show-stopper at the top of the range is enough to genuinely shift the project number, particularly on a deck over about 25 m². Picking the right composite is mostly a question of how big the deck is and how it'll be used. The honest answer is this: on smaller decks and feature areas, Pioneer becomes the easy choice. On larger ones, the maths gets harder, and the right answer changes.

Those are our published 2026 ranges, live on the Endure pricing page. They cover the boards, the substructure, the labour, the design, the prelims, the warranty and a 12-month DeckCare return. They do not cover anything we haven't quoted on — site works on a difficult block, demolition of an existing deck, electrical, structural engineering on elevated builds. That sits as a separate line if it's there at all.

For context: the general Perth market for installed composite lands roughly $295–$600/m² inc GST across published competitor rates. We sit above that band. We're open about it. The honest version of why is the hub article on how decks really get priced in Perth: you can build a deck cheaply or you can build one to the 20-Year Standard with a 7-year structural warranty. You can't do both for the same number.

There are a lot of composites in market. In Perth, three boards do most of the work — and each has a clear job.

Eva-Last Pioneer — the show-stopper

This is the favourite. Ultra-realistic composite, deep grain, a finish that reads as timber once it's down — when a Pioneer deck is in front of you, the timber-versus-composite question stops mattering. It is the board that turns the deck into the centrepiece of the whole house. Sits at the top of the composite supply market — meaningfully above the rest — but on the right deck the result is on a different planet.

Pioneer is the hero on smaller decks, feature areas, and decks that sit inside a bigger outdoor build. Reason: the supply-cost gap to other composites multiplies by square metres. On a small deck — say 15–30 m² — the cost difference between Pioneer and a lower-tier composite is genuinely modest, because you aren't multiplying the supply-cost gap by much area. The stretch is small, and the result lands at a different finish entirely. On a 50 m² or 70 m² deck, the same per-metre gap turns into a five-figure difference and the maths gets harder. On a smaller deck or a feature area, Pioneer becomes the easy yes. On a big one, it's a decision.

(And if budget ever allows you to do a 60 m² Pioneer deck — honestly, you might end up on Better Homes and Gardens for the best deck in the country. Worth saying because it isn't far off the truth.)

MoistureShield Meridian — the cool one for full sun

The right board when the deck is exposed to full Perth sun without overhead cover. Composite in direct summer sun gets hot. Hot enough that walking on it barefoot stops being an option — which means a deck that gets used less than the homeowner expected. MoistureShield Meridian uses a CoolDeck heat-reflective technology that the manufacturer rates as roughly 35% cooler underfoot than standard composite, which is the difference between a usable summer deck and a deck that bakes from 11am to 4pm.

If your deck is going under a roof, screening, or a tree canopy that knocks the worst of the afternoon sun off, this advantage matters less. If it's exposed — west-facing, open to the sky, no overhead cover — MoistureShield is the right call. The other path is to specify a different composite and design a semi-permeable overhead structure into the project from the start, which is its own decision.

Eva-Last Infinity — the accessible composite

The value composite within a credible brand. Genuinely cheaper at supply than the premium tier, capped, real composite — not a budget WPC. The right board when:

• Composite is the right call for maintenance and lifespan reasons, but the deck is large enough that the supply-cost gap to a premium board becomes a real budget conversation.
• The deck will sit under overhead cover, so the look of the board matters less than the practical advantages of going composite.
• The project is staging composite into a bigger outdoor build where the budget needs to land elsewhere too.

There's also a US-made capped composite, Trex Transcend, sometimes specified when the client wants the long brand-backed warranty story specifically. We specify it when the brief calls for it. Sits in the same upper-band tier as MoistureShield and Pioneer on supply.

The composite market doesn't have one upper-tier price. It has a real spread, and the spread is genuine product difference — not pricing fog.

Pioneer, MoistureShield Meridian, and Trex Transcend are all upper-tier composites and they all behave differently. Different caps, different cores, different finish systems, different warranty structures. Their supply costs sit in a similar upper band, but with material gaps between them. Eva-Last Infinity sits a clear tier below — capped, real composite, but a genuinely cheaper product than Pioneer despite both wearing the Eva-Last name.

Across a 30 m² deck, the supply-cost gap between the accessible composite and the show-stopper at the top of the market easily runs into a five-figure delta by the time it travels through the build. That's not a markup. It's the supply line itself — boards are not interchangeable, and the quote shouldn't pretend they are.

If a builder is happy to swap "the composite board" without changing the quote, that's a red flag. It usually means they were guessing on the original number.

The boards are the headline. They are usually a quarter to a third of the total on a composite job. The rest is structure, labour, and the things that keep the deck standing.

The subframe. Every composite deck sits on a frame, and Perth weather kills frames regardless of what's on top. Generic decking subframe runs around $75 per square metre at most Perth builders. Ours sits closer to $85–$95 per square metre because we run H4 bearers, joist tape on every joist, tighter spans and more concrete per footing. The boards on top might last decades; the subframe is what decides whether they get to. The deeper read is in the substructure cost article — and it makes the same point with more detail: a composite deck sits on a subfloor, not a slab of timber. Build it that way.

Labour. Roughly a third of the total on most composite jobs. Composite labour is cheaper than timber labour — composite is more efficient to lay, with uniform profiles and hidden-clip systems on most boards. Timber needs wedging, pre-drilling, screwing. The full read on why labour matters this much — and why a cheap labour line is the single biggest tell on a quote — is in the labour cost article.

Prelims, stairs, additions. Engineering drawings, council plans, site setup, end-of-job clean — around $1,050 ex GST on a standard job. Stairs aren't included in the per-m² rate, because they aren't a per-m² element; a standard 3-rise stair set runs a couple of thousand inc GST depending on the board. Cladding, screening, lighting, additions — each is a separate line on a full outdoor project.

Design. For standalone deck builds that need council approval, Endure runs a paid design phase — a $1,200 design fee, credited toward the build. For full outdoor builds the design phase is a $3,500 Paid Design Agreement, also credited. For a simple deck on an existing slab where no council is involved, there's no upfront design fee at all. Full read: Our Process.

The warranty and the year-one return. Every Endure deck carries a 7-year structural warranty plus the board manufacturer's warranty on top. The boards we use carry long brand-backed written warranties (Trex Transcend in particular carries an especially long one). We've had no claims yet on any composite we've installed — every install is to manufacturer spec. What composite warranties give you is peace of mind that timber genuinely can't supply. None of it is a line on the quote. It's inside the margin.

Composite is hot in summer Perth sun. Hot like walking on artificial lawn kind of hot. Timber decks are noticeably cooler underfoot because timber doesn't absorb radiant heat the same way a polymer-and-fibre composite does. On an exposed, west-facing deck with no overhead cover, mid-afternoon in February, the surface can stop being trafficable barefoot.

This is the variable nobody mentions in a composite quote and the one that quietly decides whether a deck gets used or avoided. Two practical answers:

• Specify a heat-reflective composite where it matters. MoistureShield Meridian's CoolDeck tech is rated at roughly 35% cooler underfoot than standard composite. It's a real difference on a real summer afternoon. On an exposed deck where the brief is "we want composite," this is the right call.
• Design overhead cover in from the start. A semi-permeable roof — louvres, slatted pergola, shade structure — knocks the worst of the radiant load off the deck and broadens which composite you can specify. A roof was probably going on the project anyway; designing it with the deck rather than as a later add-on changes the available board choice.

The wrong move is to pretend it isn't a factor on a Perth deck. We won't, and a builder who doesn't raise it isn't doing you a favour.

Yes. More than people think.

Composite doesn't rot. The subframe underneath it can. A long-warranty composite board sitting on a subframe that fails years before the boards do is a much shorter deck than the box says — because once the frame goes, the only way to fix it is to lift every board, replace the structure, and re-lay. By that point a re-deck is the cheaper option. We've seen it on jobs we didn't build. It's not a hypothetical.

This is why the subframe spec line in a composite quote matters as much — sometimes more — than the board choice. Questions to ask: what treatment level is the timber (H3 or H4)? Are joists taped? What are the spans? What are the fastener metals? For composite specifically — what joist spacing has been spec'd for the board you've chosen? Different composite boards want different spacing. Some boards span 450mm centres comfortably. Others want 400mm. A handful want 350mm. A builder who quotes "joists at 450" without checking the board manufacturer's published spacing for the specific composite is a builder building toward a sag.

A composite deck on a cheap subframe is a deck where the boards outlast the frame. That's not a deck. That's an expensive material applied to a problem nobody solved underneath it.

Here are the real numbers from a recent quote — a 36.57 m² composite deck (6.9m × 5.3m) on a standard timber subframe, with a 3-rise stair set. Three composite options, same deck:

Three boards, same deck, a spread of about $7,000 across the choice. That's the supply-cost difference travelling through the build into the client number.

On the same job, if the subframe was upgraded to H4 across the board, the delta was about $1,400. If it went to an aluminium subframe, the delta was about $3,100. Decisions made in the design stage, not added later.

The point of putting this here isn't to suggest one option is better than another. It's to show that the gap between composite quotes — both within a brand and across brands — is genuine product difference, not pricing fog. The homeowner who walks away knowing which board is on their quote walks away knowing what the number actually means.

Three questions, including ours.

One. Which exact board, by name and grade? Not "composite" or "premium composite" or "an Eva-Last board." The exact product name. The supply gap between the accessible composite and the show-stopper at the top of the market is real, and the quote needs to be specific.

Two. What's the substructure spec — treatment level, joist spacing, fixings, clearance, water management? A composite deck on a substandard frame is the most common quiet failure mode we see in Perth. A vague answer to this question is the single biggest tell on a quote. Specifically for composite: what joist spacing has been specified for the chosen board? Each board has a published requirement.

Three. What is not included in this quote? Site works, electrical, demolition of an old deck, structural engineering on elevated builds. If the answer is "everything's included," ask about each specifically. Most surprise costs on a Perth deck build aren't surprises — they were just not in the quote.

The full version of the three-questions framework is in our hub article on Perth deck pricing.

What does composite decking cost in Perth per square metre? Supply + install for an Endure-spec'd deck inc GST: roughly $540–$660/m² for the accessible Eva-Last composite tier and $640–$760/m² for the upper-tier composites (MoistureShield Meridian, Trex Transcend, Eva-Last Pioneer) at the 20-Year Standard build spec. General Perth market runs $295–$600/m² across published competitor rates.

Which composite is the best for a Perth deck? It depends on the deck. Eva-Last Pioneer is our hero — an ultra-realistic, show-stopping board that's the easy call on smaller decks and feature areas, where the supply-cost gap doesn't multiply across much area. MoistureShield Meridian is the right call when the deck is exposed to full sun without overhead cover — its CoolDeck heat-reflective tech runs roughly 35% cooler underfoot than standard composite. Eva-Last Infinity is the value composite for larger decks where the budget needs to land elsewhere.

Is composite hot in summer in Perth? Yes — hot like walking on artificial lawn on an exposed afternoon. Timber decks are noticeably cooler underfoot. On an exposed deck, two answers: specify a heat-reflective composite like MoistureShield Meridian, or design overhead cover (a roof, louvres, a semi-permeable shade) into the project from the start.

What's the difference between Eva-Last Infinity and Eva-Last Pioneer? Two genuinely different products from the same brand. Infinity is the accessible composite — capped, real, but a clear tier below Pioneer in supply cost and finish. Pioneer is the show-stopper — ultra-realistic, deep grain, the upper end of the composite market. The gap between them grows with deck size: small decks make Pioneer accessible, large ones turn it into a budget conversation.

Does composite still need a quality subframe? Yes. Composite boards do not rot; subframe timber can. A composite deck on a generic subframe is a deck where the boards outlast the frame. The subframe is where the long-term outcome is decided. See Why decks fail in Perth for the breakdown.

How long does a composite deck last in Perth? The boards carry long brand-backed written warranties — typically decades when the deck is built and maintained to manufacturer spec. The deck itself lasts as long as the subframe underneath does. We've had no warranty claims on any composite we've installed.

Is Endure expensive compared to other Perth deck builders? Yes — approximately 20–30% above typical Google-search-result Perth deck builders. Our pricing page carries that question directly and our hub article walks through what the difference buys: a paid design phase, fixed-price quoting, the 20-Year Standard build method, a 7-year structural warranty, a dedicated PM and a 12-month DeckCare return. If you want the cheapest composite deck in Perth, we are not the right builder — and an honest cost-led builder will deliver one for you. If you want the deck still standing properly at year fifteen, we are built for that.

If you want a real number for your block, your dimensions and your board choice — not a ballpark — that starts with a conversation. We'll walk through which composite makes sense for your aspect, what substructure spec your build needs, and what the all-in figure looks like.
