Timber Decking. How much does it REALLY cost?
When it comes to timber decking, we understand that price matters (along with many other factors). One of the most common questions we are asked is “how much does timber decking cost?”
As you might imagine, the problem with answering this question is the fact that timber decking comes in so many different timber species and can be installed in different designs and environment types. It can be tough to truly know the price of a fully installed timber deck.
However, planning and budgeting is an important part of any decking project. We’ve put together a guide on the cost of timber decking to get you started. For an accurate project-specific quote, get in touch with our timber specialists at Mortlock Timber.
How much does Timber Decking cost?
Most timber decking projects cost between $300 – $400 per m2 and can be as high as $500 p/m2. This includes all the materials supplied and installed.
As a guide, you can expect to pay:
- $6400 to $10,000 for a 20m2 deck
- $9600 to $15,000 for a 30m2 deck
- $12,800 to $20,000 for a 40m2 deck
These estimations are based on the full pricing of materials and installation including:
- Digging stump holes
- Installing concrete stumps
- The subfloor, including joists and bearers
- Installing the decking
However, it’s important to remember that the final price of a hardwood deck can vary depending on a number of other factors such as:
- Height from the ground
- Shape / design
- Material selected
- Additional options like edging timber screening and other finishing touches.
Timber species for decking – Cost comparison
Choosing the right timber species for your deck is critical for a long-lasting timber deck. Lower durability timbers like treated pine are a cheaper option and may be suitable if you are looking for temporary timber decking.
However these timbers are not as durable or long-lasting as some hardwood timber options. The longevity and durability of timber species should be taken into account when considering the lifetime cost of timber decking.
At Mortlock Timber, we offer a range of tried and tested hardwoods for timber decking such as Jarrah, Merbau, Blackbutt and more. Choosing the best timber for decking comes down to aesthetic preferences and environmental factors.
Our most popular species include:
- Blackbutt $110 – $200 p/m2
- Burnt Ash $150 – $280 p/m2
- Fijian Mahogany – $100 – $130 p/m2
- Ironbark $110 – $200 p/m2
- Pacific Teak $110 – $200 p/m2
- Spotted Gum $110 – $200 p/m2
- Jarrah $85 – $200 p/m2
Pricing above is indicative and is only for the supply of the decking material. It does not include GST or installation. The price range is for the most popular options, it does not cover every option available for each species. For accurate pricing please contact us to discuss your project.
All of these are quality timbers that can be used for exposed and covered decking. While there are advantages and drawbacks with each timber, you can be sure these are the safest options for timber decking in Australia’s harsh climate.
Other factors that affect timber decking prices
- Ground Height
It is recommended where timber decking is exposed to the weather that it has 300-400mm ground clearance. Adequate ventilation is critical for preserving the structural integrity of your decking.
This means you need a timber or steel subframe underneath the decking to elevate it off the ground. The higher the timber deck is off the ground, the more material you are going to need which drives the cost up.
- Timber Board Size
Standard timber decking board sizes are:
At Mortlock, we offer additional board sizes of:
These larger board sizes are generally used for commercial projects and high traffic areas. For residential projects, a 19mm or 20mm thick decking board is generally durable enough.
Choosing a 30 and 40mm thick board means more timber per m2, bigger screws and a heavier deck. All of these factors will drive the cost up. In fact, choosing a 30 or 40mm thick board size can add between $80 – $200 per m2 for the timber decking material depending on the timber species selected.
- Substructure Materials
The substructure underneath the decking is usually made from treated pine. However in some cases a hardwood substructure is required for fire purposes. Hardwood substructures are more expensive and will drive up the overall cost of the decking.
- Decking Contractor Costs
At Mortlock Timber, we manufacture and supply quality hardwood decking. We do not provide installation services and therefore do not control the price of installation.
While we do provide materials directly to customers, we highly recommend you engage a decking contractor or a qualified carpenter to install your deck and help you work out the quantity of material required.
Using a decking contractor or a qualified carpenter means your deck will be installed correctly and in accordance with the relevant building regulations in your state. The price of decking installation may vary from contractor to contractor.
Mortlock Timber Decking Options
The specific decking profile you choose may affect the final timber decking price. At Mortlock, we offer three premium timber decking options.
- Metroplank Concealed Fixed Timber Decking
Metroplank is a concealed fixed decking system which hides the screws from the surface of the board. It is expertly designed to cater for the natural movement of timber. This classy profile is ideal for alfresco areas and verandahs.
- Marineplank Durable Timber Decking
Marineplank Timber Decking is a profile specially designed to be installed around pools and areas that are fully exposed to weather. However Marineplank is a highly versatile profile and can be used for all decking applications.
It is profiled with a slight domed top surface. This increases water run-off meaning the timber is less likely to move and will last much longer than traditional flat top decking.
3. Classicplank Timber Decking
Classicplank is a premium grade traditional flat top decking with a timeless and elegant finish. Whilst we recommend to use this for covered outdoor areas, some timber species are suited to fully exposed applications.
