Partially renovated timber deck with support posts and window

Decks Built to Handle Perth Conditions

A deck in Perth isn’t just outdoor flooring — it’s a surface that sits in direct UV most of the year, gets hammered by salt air in coastal suburbs, and needs to handle the 45°C days where some materials warp or crack.

We’ve built enough decks across Perth to know which timbers hold up near the coast, which composite brands don’t expand too much in the heat, what subframe spacing actually prevents bounce, and where drainage goes wrong before it becomes a repair job.

Before any board goes down, we sort the base: ground clearance for airflow, fall for drainage, bearer and joist spacing that matches the decking material — not the generic spacing every DIY guide suggests. A level frame on stable footings means the deck stays flat and safe for years, not just months.

Timber decks get oiled at completion. Composite decks get installed with the right expansion gaps and hidden fasteners. Both get built knowing they’ll be inspected in full sun by a homeowner who’ll notice every ripple.

Timber vs Composite: What Actually Works

Timber decking (Merbau, spotted gum, treated pine) needs oiling every 12-24 months but gives you that natural timber look and feel. It’s what most people picture when they think “outdoor deck”. The upfront cost is lower than composite. It can be sanded and refinished if it weathers unevenly. In coastal areas within 1km of the beach, hardwoods like Merbau hold up better than softwoods.

Composite decking (various brands, we’ll walk through options) doesn’t need oiling. You hose it down once a year. It won’t splinter, rot, or attract termites. The colour stays consistent because it’s not relying on oil penetration. The upfront cost is higher — sometimes 40-60% more than mid-grade timber — but there’s no ongoing oiling labour or product cost. It does expand and contract with heat more than timber, so gap spacing and fastener choice matter.

We’re not brand-loyal to either material. Some clients want timber because that’s the aesthetic they’re after. Some want composite because they’re done with maintenance. We install both properly, with the right subframe, fasteners, and finishing details for each material type.

If you’re not sure which suits your situation — budget, how hands-on you want to be, salt exposure, shade cover — we’ll walk through it on-site and explain what each choice actually means in year 5, not just at install.

What Decking Installation Covers

From base preparation to final board placement — the full scope of a professional deck build.

Site Assessment & Layout

We measure the space, check ground conditions, identify drainage requirements, and mark out the deck footprint. Before any timber gets cut, you know exactly what’s being built and where.

Subframe Construction

Footings, bearers, joists — the hidden structure that keeps the deck level and stable. Correct spacing for your chosen decking material, proper fall for water runoff, and treated timber rated for ground contact.

Drainage & Airflow

Ground clearance underneath for ventilation, slight gradient so water doesn’t pool, and clearance from house brickwork to prevent moisture wicking. Small details that prevent big problems.

Board Installation

Decking boards laid with the correct gap spacing (different for timber vs composite), fastened with stainless steel or composite-specific screws, and all cut ends treated or sealed. No mushrooming, no squeaks.

Finishing & Protection

Timber decks get an initial oil coat. Composite deck edges get fascia boards to hide the subframe. All exposed cut ends are sealed. The deck is left clean, safe, and ready to use.

How a Deck Build Works

From first contact to final handover — here's what happens.

Initial Enquiry

You contact us with your deck project. We ask a few questions to understand what you’re working with.

Site Visit & Quote

We visit your property, measure the space, check ground conditions, and discuss material options. You get a written quote with scope and price.

Materials & Scheduling

Once you approve the quote, we order materials and confirm a start date. Deck builds typically run 3-10 days depending on size and complexity.

Build & Handover

We build the deck, clean up the site daily, and hand over a finished deck ready to use. Timber decks are oiled. Composite decks are wiped clean.

Decking Questions

Depends on size, material, and site conditions. A basic 20m² treated pine deck starts around $4,000-$6,000. Mid-grade hardwood (Merbau, spotted gum) runs $6,000-$10,000 for the same size. Composite decking adds 40-60% to the hardwood price but removes the ongoing oiling cost. Pool surrounds, multi-level decks, and difficult access all push the price up. We give you a written quote after measuring the site — no guessing.

Usually no for ground-level decks under 500mm high and not near the street boundary. Raised decks, decks attached to the house above a certain height, or decks within setback zones typically need a building permit. We’ll tell you if your project needs approval when we visit the site. If it does, you’ll need engineered drawings and a building surveyor sign-off before we start.

With regular oiling (every 12-24 months), a hardwood deck in Perth lasts 15-25 years. Treated pine lasts 10-15 years if maintained properly. Coastal properties see faster UV and salt degradation, so hardwoods are the safer bet near the beach. The subframe typically outlasts the boards if built with treated H4 timber and stainless steel fasteners.

Quality varies. Some composite boards are 60% wood fibre and fade or stain easily. Others are 90%+ polymer and hold colour better but cost more. Expansion rates differ too — cheaper composites can expand 5-8mm per metre in Perth heat, which causes buckling if gap spacing isn’t right. We use brands we’ve installed before and know perform in WA conditions. If you’ve seen a particular brand you like, we’ll tell you honestly if it’s suitable.

For timber, yes — we can oil new boards to blend with the existing deck, though natural timber colour varies batch to batch. For composite, new boards will match the manufacturer’s current run, but older composite decks may have faded or changed colour slightly. We’ll bring samples to your site before ordering so you can see the colour match in your actual lighting.

Yes. If you’ve got an old deck that needs replacing, we’ll price the demolition and disposal as part of the quote. Old timber usually goes to green waste. Old composite can sometimes be recycled depending on the brand. We clear the site completely before starting the new build.

We adjust the footing heights to compensate. A deck doesn’t follow the ground — it’s built level on footings of different heights. If the slope is severe, we might recommend retaining or terracing before the deck goes in. We’ll tell you what’s needed when we assess the site.

Yes. Stairs, step-downs, and access ramps are all part of standard deck builds. Stair height, tread depth, and handrail requirements are set by the Building Code. We’ll build them to code and make sure they’re stable and comfortable to use.
