Decking Perth

Timber And Composite Decking Across Perth

Decking extends your living area out into the garden, where you can socialise, relax and entertain. Outdoor decking creates a defined entertaining area, turning ground you barely use into the best space on your property.

Landscape By Design has been building decking Perth-wide for over 30 years, in timber and composite, as a standalone project or part of a full landscape design.

As professional deck builders, we keep the job with one team from first consultation to completed deck, with no chasing installers and trades.

What Is Decking?

Decking is a ‘lifestyle’ concept that extends your inside living area to the outdoors, where you can socialise, relax and entertain. It’s also true that decking makes your home look great too.

Decking looks more natural and blends in with the look of your garden a little more than a patio, though both options are a great choice. It creates a unique look in your garden and adds a dimension of interest.

It is also an excellent solution for concealing uneven terrain, rocky patches, or areas where grass struggles to grow, providing a level and stable surface for outdoor activities.

Decking Material Options at Landscape by Design

Your decking material sets the look, the maintenance and how long the deck lasts. Perth’s climate features intense summer UV radiation and coastal salt air, so the two are not interchangeable.

We supply and install both, with honest advice on what suits your site.

Timber Decking

Natural hardwoods offer authentic warmth and stay cooler underfoot than synthetics, which matters in February. Timber decking options include Merbau and Spotted Gum. Merbau is a tropical hardwood known for its stability and termite resistance. Timber gives natural variation in appearance no board can match, and needs periodic maintenance to preserve it.

Composite Decking

Composite decking combines timber’s look with modern durability and is designed to handle Perth’s tough climate. Composite boards will not warp or splinter in the heat, and quality composite decking can last up to 25 years.

It requires no sanding or staining, so we recommend it to anyone wanting a low-maintenance deck.

Composite is often more expensive than timber up front and lasts longer in harsh climates, so it comes down to whether you prefer the natural look or the sleek finish and lower upkeep.

How to Look After Your Deck

Timber decking needs regular maintenance like sealing and staining to hold its colour, plus oiling and occasional sanding as it ages, which extends its life. Composite decking requires less maintenance than timber decking: no sanding, sealing or painting, just a wash down.

Quality decks are easy to maintain and long-lasting either way, and we hand over clear advice on how to maintain yours.

How We Build A Deck That Lasts In Perth

The part of a deck you never see decides how long it lasts. We plan the structure beneath the boards, the fixings and the airflow underneath first, because heat movement, salt air and trapped moisture are what shorten a deck’s life here. We build with durable materials that perform here, not the cheapest boards on the market.

Detail matters above the frame too. Using lighter board colours on decks can prevent excessive heat absorption in summer, so it stays usable through the hottest months. Next to a pool or any wet area, a brushed finish or non-slip strips are essential for safety and WA compliance.

And council approval is needed for decks raised over 500mm, so we tell you where yours sits and handle the approval.

Decking and Your Home

Is Landscape Decking Right for Your Outdoor Space?

If you’ve been considering decking for a while, we’ve highlighted the following benefits to help assist with your decision.

Frequently Asked Questions about Decking in Perth

How do you clean decking?

For most decks, a sweep and a wash with warm water and a soft broom is all it takes, with a mild soap for stubborn marks.

For mould or green growth, oxygen bleach is the gentlest option that actually works, and unlike chlorine bleach it will not strip a timber finish or lighten the boards.

Keep pressure washers on a low setting, or off timber altogether, because high pressure raises the grain and causes splintering.

Does composite decking get hot?

Yes, and it is worth knowing before you choose. Composite holds more heat than timber, and natural hardwoods stay cooler underfoot than synthetics. Using lighter board colours prevents excessive heat absorption in summer, so the colour you pick matters as much as the material.

If the deck faces west, or you are barefoot around a pool all summer, we will talk you through lighter composite boards, shade from a pergola, or timber instead.

Is composite decking better than timber in Perth?

It depends what you want from it. Composite requires less maintenance, handles Perth’s climate and can last up to 25 years, so it wins if low upkeep matters.

Timber gives authentic warmth, stays cooler underfoot and offers variation no board can copy. We build decks in both and advise honestly for your site.

Can you paint composite decking?

We do not recommend it. Composite boards are manufactured with the colour running through them and a surface designed to shed water, so paint does not bond well, and painting usually voids the manufacturer’s warranty. The upside is that you do not need to.

Composite requires no sanding, sealing or painting, so choose the colour at the selection stage, because that is the colour you keep.

Which form of timber is best for decking?

There is no single best hardwood, only the best one for your site. Merbau is a tropical hardwood known for its stability and termite resistance, which makes it a safe all-rounder. Jarrah is a local hardwood with a deep, rich colour and natural resilience. Spotted Gum is known for fire resistance and has beautiful varying tones, so it is the one to look at where bushfire resistance matters.

All three need periodic oiling to hold their colour.

Do I need council approval to build a deck in Perth?

Council approval is needed for decks raised over 500mm above ground level, and requirements vary between councils. A low-level deck usually does not need it. We check where yours sits before we start and support you with the approval.

Can you build decking around an existing pool?

Yes, and it is one of the most popular projects we take on. Composite is usually our recommendation because it resists pool chemicals and will not splinter underfoot, and we make sure the surface is non-slip where wet feet are expected.
