Softwood and Hardwood Price Comparison

Generally, hardwood will be more expensive than softwood timber decks.

The cost per square meter for a basic deck using softwood timber is typically between $150 and $250. This includes the cost of the materials, such as the timber, screws, nails, and sealant, as well as the labour required to build the deck.

For example, a 20sqm softwood timber deck could cost between $3000 and $5000. This cost would include the material costs and labour costs.

Hardwood timber decks can cost more than softwood timber decks depending on the timber used. The cost per square metre for a basic hardwood timber deck can range between $250 and $450. This includes the cost of the materials, such as the timber, screws, nails, and sealant, as well as the labour required to build the deck.

For example, a 20sqm hardwood timber deck could cost between $5000 and $8000. This cost would include the material costs and labour costs.

In addition to the cost of the materials and labour, there may be additional costs, such as for screws, sealant, and any other items needed to complete the deck. Therefore, it is essential to factor these items into the total cost before commencing with the deck’s building.

Average Price Ranges for Different Types of Decks

The following is a list of price ranges for different types of popular options of timber in Australian dollars.

Factors that Affect the Average Cost of Decking

The cost of a timber decking project can vary significantly depending on the factors listed below:

A. Size and Layout of the Deck

The size and layout of the deck will directly impact the number of required materials as well as the complexity of the labor involved. For example, a larger deck with more complex features (e.g., multiple levels, built-in seating, elevated deck, etc.) will cost considerably more than a smaller, simpler one.

B. Type of Timber Used

The timber used in the deck will also affect the price, as some woods are more expensive than others. For example, hardwoods such as jarrah and Merbau will generally be more costly than softwoods like spotted gum and blackbutt.

C. Extras and Accessories

Accessories such as railings, stairs, and pergolas can significantly add to the overall cost, depending on their size/complexity and material choice.

D. Labor Costs

Labor costs should be considered when planning for a timber decking project – they can often account for up to half of the total bill due to their complexity and time-intensive nature. Furthermore, specific locations may have higher labor rates due to their geographic location or other market factors.

E. Location and Climate Conditions

Location is another factor that can influence costs due to weather conditions (e.g., a coastal area may require treated timbers due to its exposure to salt). The climate conditions in your area may also affect your budget; for instance, if you experience extreme temperatures, you may need to take additional measures such as installing additional support or purchasing insulated materials – both of which could add up quickly depending on how much is needed/how complex they are to install/source.

F. Quality of Materials Used

Quality is essential when using timber in any construction project; using cheap materials may result in premature wear or structural failure over time, leading to higher expenses down the line at best or severe injury at worst! On the other hand, investing in quality materials upfront is usually worth it in terms of longevity and reliability, so always buy from trusted sources when possible.

G. Additional features

• Railings: Require specialised tools and skills to install correctly, leading to increased labor time, material costs, and prices.
• Stairs: Must be adequately constructed for safety purposes – requiring detailed planning and considerations.
• Built-in seating: Adds charm and character but may require extra measures (e.g., additional support or insulation). Detailed planning is essential for long-term use.

DIY vs. Professional Installation Costs of timber decking

• DIY: Can save money in the short-term but often needs to consider additional labor costs, materials, and expertise required for complex projects.
• Professional: Can offer peace of mind with quality workmanship, often with a guarantee/warranty included. Savings may offset additional costs due to more significant expertise and longer labour hours from bulk purchases of materials.

Estimating the Cost of a Timber Deck Project

• How to calculate Material Costs: You can research prices for wood, nails, screws, sealants, and other items needed for the project. It may also be necessary to factor in the extra cost of materials for surprises or repairs.
• How to calculate Labor Costs: Consider project complexity, skill level, and time required from a professional tradesperson or handyman – if help is needed.
• Estimating Total Cost for a Project: Once material and labor costs are accounted for, the total cost can be estimated by adding them together and adding a buffer amount of 10–20%, depending on the size of the project.
• Budgeting for Unexpected Expenses: Unexpected costs can arise due to unforeseen changes in building codes, modifications in plans, or sudden shifts in weather conditions leading to additional expenses such as waterproofing or insulation needs. It is wise to plan ahead with an adequate budget allowance that can consider such possibilities and raise the initial cost.
