How Much Does Trex Deck Cost in Sydney?

Don’t let the pricing of your new deck floor you. Our simple Trex deck price guide will help you to make informed choices. 

Trex deck products are unmatched if you’re considering installing composite decking. It’s the best-known composite material that’s available. To give you a better idea of its popularity, they contribute to about 40% of the composite market, making them the leading provider of composite materials. 

Though, as you would expect, it does come at a cost. It’s more expensive than hardwood timber but offers many advantages. They’re a significant investment. Continue reading to find out how it compares to timber decking and what you can expect to pay for it on average. 

What’s a Trex deck?

Trex® deck is a composite decking that is sustainably manufactured in the USA. The company was formed in 1996 and is regarded as the world’s number-one decking brand. They were the first company to combine reclaimed wood’s natural beauty with recycled plastic’s durability—the result – a high-performance decking product that can be used for a wide variety of outdoor uses.

Trex decking materials are made up of 95% recycled materials. In addition to plastic, it also includes timber, sawdust, and wood grain fillers. It also offers great customization and is available in several colours to complement your home’s current style. 

Trex vs. timber decking

Trex decking products have several advantages over natural timber. So, exploring timber-alternative products for your decking project is worthwhile. 

Trex offers natural resistance to scratches and stains, unlike timber. This includes protection against the elements. Plus, it’s also termite-proof!

Secondly (and this is a significant benefit today), it’s much kinder to the environment. Instead of cutting down new trees, it uses unwanted timber like sawdust and recycled hardwood furniture. As mentioned, 95% of it is made up of recycled materials. 

Not only does it use reclaimed wood and recycled plastic, but they also ensure that its manufacturing processes are greener by using a sustainable supply chain. All their supply vendors operate ethically and responsibly. 

But it doesn’t stop here. The company also works with other US Green Building Council members to see where they can change the building industry to create more environmentally friendly spaces. 

Factors that impact the cost of Trex  decking 

If going the Trex route makes the most sense for your building project (it certainly does from an environmental point of view), there are a few things that you need to keep in mind that could impact its affordability. In short, professional designers and installers base their estimates on the size and time. 

While it won’t surprise you that a larger deck will cost you more, you might not have realized that design details can bump up the price. So, when planning your decking, remember that you’ll need more Trex decking for edging and to achieve other elaborate finishes. So, if cost is a significant concern, opt for straight sections instead of intricate curved designs.

You will need more material, and extra elements like edging and fascia will require more time to design and install. And, as you know, time is money. 

Another factor that can impact the cost of Trex decking is the condition of the substructure. If the existing substructure is damaged or needs repair, it can add to the project’s overall cost. Inspecting the substructure before installing Trex decking is essential to ensure it is in good condition and will not need replacing in four or five years.

Trex decking is warranted for 25 years. You don’t want to have to take up the newly installed Trex deck boards at a later stage because the substructure is starting to fail and become dangerous.

The costs of Trex composite decking in Sydney

So how much does Trex cost? Depending on your preferred design, you’re looking at paying between $207 –  $230 a square metre for the deck boards. 

You’ll also need to keep in mind labour and installation. This can vary significantly based on your deck’s design, location and substructure requirements.

If your deck is low to the ground and the substructure could be at risk of rot, you need to consider using either h4 low deck timber (specially designed for low decks and with a 40+ year warrant) or aluminium or steel substructures.

These add a premium to the cost of your deck but will give you peace of mind as you won’t have to spend countless thousands of dollars repairing the deck over the years.

If termites are a concern in your location, you can rest easy knowing that Trex decking is not affected by them. The substructure, though, could be a problem. In this case, you would be better off going to aluminium or steel. If your installer or builder suggests that treated pine is acceptable in a termite area, you may consider using another installer.

A Trex deck properly constructed using the correct materials will cost about $700 and upwards of a square metre – remember that’s subject to any special requirements your project may have.

It’s not unreasonable for you to expect your deck to last 25 years or more without requiring significant repairs.

The complexity of deck design

The more complex the deck design requirements, the more is added to the cost through materials and installation. 

There are many features that you can add to a deck to enhance its functionality and aesthetic appeal, which will ultimately add to its cost.. Here are some of the most popular features:

Railings: Adding railings to your deck can improve safety and the overall design aesthetic. Railings come in various materials and styles, including wood, metal, and glass.

Lighting: Adding lighting to your deck can create a warm, inviting atmosphere and increase safety. Options include string lights, solar lights, recessed lights, and more.

Built-in Seating: Adding built-in seating to your deck can save space and create a cosy gathering area. Benches, sofas, and lounge chairs can all be integrated into the design.

Fortunately, an experienced installer can use the flexibility that Trex decking provides to provide you with most of the options listed above.

Site considerations

When building a deck, several site requirements need to be considered to ensure the safety and longevity of the structure. Here are some of the most important site requirements for decks:

  1. Building Codes: Before starting any deck project, checking local building codes and regulations is important. Building codes will outline the minimum requirements for deck construction, including required setbacks from property lines, minimum railing heights, and maximum load capacity.

  2. Soil Type: The type of soil on which the deck will be built is important to consider. If the soil is prone to erosion or has poor drainage, adding drainage features or a foundation that can withstand these conditions may be necessary.

  3. Slope: The slope of the ground where the deck will be built is another important factor to consider. If the slope is too steep, building a raised deck or additional supports may be necessary.

  4. Sun Exposure: The amount of sun exposure the deck will receive is also important. If the deck gets a lot of direct sunlight, adding shade structures or choosing materials that won’t become too hot in the sun may be necessary.

  5. Wind Exposure: The amount of wind exposure the deck will receive is also important. If the deck is in an area with high winds, it may be necessary to use stronger materials and reinforce the structure to prevent damage.

  6. Drainage: Proper drainage ensures water does not pool on the deck or around its foundation. The site should be graded to ensure proper drainage and additional drainage features may be necessary.

  7. Utilities: If the deck will be built near utilities such as gas or electrical lines, it’s important to consider their location and potential impact on the project. You may need a professional to locate and mark any underground utilities.

  8. Is the site difficult to access?  Additional costs may be incurred if it is difficult to get materials to and from the site.

Getting a detailed quote with everything you want included is a good idea. That way, you can sit down with your installer or builder to see how to fit it into your budget.

Trex is the most affordable composite decking solution available. The table below shows how it compares in terms of price to other types of composite decking in Sydney:

MaterialThe average Trex decking price per square meter before waste and fasteners
Trex$207
Azek$190 – $339
Millboard$334 – $422

While Trex will initially be more expensive than timber, it’s cost-efficient as it requires no regular maintenance and in the hands of an experienced contractor, will be quicker to install.  Hardwood decking is  slower to install (when done correctly – no shortcuts), so along with the initial additional labour and oiling costs, the Trex deck will usually pay for itself within 3 to 5 years. 

After installing your Trex deck, there are no maintenance costs. This means you don’t have to worry about sanding, painting, or oiling. You only need soap, water, a soft bristle brush, and some elbow grease to clean your Trex boards. 

Finding an installer for your Trex deck

Considering that labour and installation can add up very quickly, you’ll want to ensure you partner with a professional installer who will bring justice to your design and material. Ideally, you’ll want to work with an installer with at least five years of building experience in Sydney. Organizing permits and ordering materials can lead to headaches before the building project starts. So, working with someone familiar with your area’s building requirements is best.

Another indication of their skill level is the previous projects they’ve completed. By looking at their portfolio, you’ll better understand their style.  

If you like what you see, you can then ask the following more direct questions to narrow down your shortlist to the one:

  • Do you have any client references or testimonials?
  • How long does a typical project take to complete?
  • Do you order all the materials, or will I need to order them myself?
  • What warranties or guarantees do you offer?
  • Will you take care of any permits or permissions required?
  • Who will be responsible for waste removal?
