How much does decking cost in Australia?

Decking cost depends on board material, deck size, subframe condition, site access, installation complexity and finishing details. It is best to calculate the approximate area first, then request a project-specific quote.

How is decking cost per m2 calculated?

Decking cost per m2 is usually affected by the board material, accessories, wastage, subframe, labour and finishing details. Square metre pricing can be a useful guide, but the final cost depends on the full project.

What affects deck installation cost?

Deck installation cost can be affected by site access, deck height, subframe work, stairs, pool areas, board layout, removal of old decking and finishing details such as borders or edge boards.

Can I calculate how many decking boards I need?

Yes. You can use the EVERTEX Decking Calculator to estimate board quantities based on your deck size. Final quantities should still be checked before ordering.

Planning a new deck and trying to understand the cost?

Decking prices in Australia can vary depending on the board material, deck size, subframe, site access, installation method and finishing details. A simple ground-level deck and a raised poolside deck may have very different costs, even if the area is similar.

This guide explains the main cost factors to check before requesting a quote, and how to use the EVERTEX Decking Calculator to estimate your board quantity.

1. Decking Board Material

The decking board you choose is one of the biggest factors affecting the total cost.

Timber decking may have a lower upfront material cost, but it usually needs regular oiling, sealing or staining over time. Composite decking and PVC decking are often compared by homeowners who want a timber-look deck with lower ongoing maintenance.

EVERTEX Advanced PVC Decking is worth considering if you want a timber-look outdoor board that does not require regular oiling or sealing.

2. Is Decking Cost Usually Calculated Per Square Metre?

Decking is often discussed in square metres, but the final cost is not only about area.

The same 30 m² deck can vary in price depending on the board type, subframe condition, stairs, access, board layout, wastage, borders and installation details.

This is why a square metre estimate can be useful as a starting point, but a project-specific quote is still important before ordering.

3. Deck Size and Board Layout

Deck size matters, but layout can also affect material quantity.

A simple rectangular deck is usually easier to calculate and install. More complex designs may need extra boards, cutting, edge boards, breaker boards or picture-frame borders.

Before requesting a quote, it helps to prepare your approximate length and width, photos of the area, and whether the project is a new deck or a replacement deck.

4. Subframe and Site Conditions

The structure underneath the deck can also affect the final cost.

A new subframe, uneven ground, limited access, raised areas, pool surrounds, stairs or removal of an old timber deck may all change the project cost.

Your builder or installer should check the site condition, drainage, ventilation, joist spacing and fixing method before confirming the final installation cost. Our installation guide outlines the recommended subframe and fixing method for EVERTEX decking.

5. Supply Only or Supply and Install

Some customers only need decking boards and accessories. Others need help with both supply and installation.

For supply-only projects, the main cost usually includes decking boards, clips, screws, plugs, edge boards and delivery.

For supply-and-install projects, labour, site preparation, subframe work, stairs, finishing details and access conditions may also affect the total price.

Not sure how many boards you need?

Use the EVERTEX Decking Calculator to enter your approximate deck size and estimate the number of decking boards required.

This is a helpful starting point before requesting a quote. Final quantities may vary depending on board direction, cutting, wastage, edge boards, stairs and installation layout.

Compare Samples Before You Decide

Price is important, but it should not be the only factor.

Before choosing decking, compare the colour, surface texture, maintenance requirements, warranty information and suitability for your project area.

EVERTEX offers timber-look PVC decking samples so homeowners, builders, landscapers and designers can compare colours and finishes before ordering.
