How Much Does A Deck Cost By Type?

The cost of decking per square metre can differ significantly and depends on several pivotal factors. The following are some of the most crucial factors that can impact the total cost of a decking project:

Price Of A Deck By Material

Building decking costs depend on several factors, including its type and the material used to construct it. There are various decking materials to consider when selecting one for your deck construction; each has unique benefits and drawbacks that must be carefully evaluated to arrive at an informed decision. Here is an overview of some popular options:

  • Timber decking: Timber decking is a classic and popular option that offers a natural look and feel. Timber decking is available in various species, grades, and sizes, with prices varying depending on the type of wood chosen. Hardwoods like Merbau or Kwila are typically more expensive than softwoods like Pine or Cedar.
  • Composite decking: Composite decking is made of wood fibres and plastic, providing a durable and low-maintenance option. Composite decking is available in various colours and finishes and typically costs more than timber decking.
  • PVC decking: PVC decking is made entirely of plastic, providing a highly durable and long-lasting option. PVC decking is resistant to moisture, mould, and insects, making it an ideal choice for outdoor use. However, it is also the most expensive decking material.

The cost to build a deck varies depending on the quality, size, and manufacturer. In general, timber decking cost is the most affordable option, followed by composite decking, with PVC decking being the most expensive. However, it’s essential to keep in mind that the total cost of decking goes far beyond its upfront material costs – this includes ongoing maintenance costs that vary significantly across materials.

Deck Size

The deck size is another important factor affecting the overall decking cost per square metre. Larger decks require more materials and labour, leading to higher deck costs per square metre.

Deck Height

The height of the deck can also impact the cost of a deck per square metre. Elevated decks that require additional support structures and safety features, such as railings and stairs, will increase the overall decking costs per square metre.

Site Conditions

The site conditions can also affect deck cost per square metre. If the site is uneven or requires extensive preparation work, such as removing existing structures, soil excavation, or grading, the deck build cost will be higher.

Labour Costs

Labour costs are another significant factor influencing the overall decking cost per square metre. The labour cost will vary depending on the location, the installer’s experience, and the project’s complexity.

Additional Features

Additional features such as lighting, railing, stairs, and pergolas can also add to the overall cost of a deck. These features can enhance a deck’s functionality and aesthetics but come at an added cost for deck construction.

Tips To Keep Decking Prices To A Minimum

For homeowners looking to keep their decking costs per m2 affordable without sacrificing quality or style, there are some useful tactics to keep in mind. Herein, we will explore valuable tips and strategies to help homeowners manage and minimize their decking expenses per m2.

Plan and Design Carefully

Careful planning and design are crucial to keep decking prices to a minimum. Start by determining the size and features you need, and create a detailed plan including all materials and labour costs. Be realistic about what you can afford and consider choosing simpler designs and features to keep decking prices down.

Choose the Right Materials

Choosing the right materials can significantly affect the cost of building a deck. Consider choosing cost-effective materials like pressure-treated pine or composite decking, which offer durability and low maintenance at a lower deck price than premium materials like hardwoods or PVC decking.

Do Some of the Work Yourself

If you have DIY skills, consider doing work yourself, such as demolition, site preparation, or staining. However, be careful not to take on tasks beyond your skill level, as mistakes can lead to costly repairs, increasing the decking price.

Get A Quote For Decking From Multiple Sources

Get quotes from multiple contractors to compare the price of decking and services. Ensure the quotes include all costs, including materials, labour, permits, and other fees. Be wary of low quotes that may indicate poor-quality work or hidden costs.

Time Your Project

Consider timing your deck-building project during the off-season, when contractors may be more willing to negotiate prices and offer discounts. Also, consider purchasing materials during sales or off-season promotions to save on costs.

Consider Maintenance Costs

Consider long-term maintenance costs when selecting materials. Staining or sealing can become expensive over time. Choose materials that require minimal maintenance to keep costs down in the long run.

Use Deck Pricing Calculators

Before starting your project, use online deck pricing calculators to estimate the decking cost. This can help you plan your budget and choose materials within your price range.

By having a clear idea of the cost to build a deck per square metre, you can avoid unexpected expenses and adjust your plans accordingly to keep costs down. Deck pricing calculators are available online and can be a valuable tool for planning and budgeting.

How Can I Save Money on the Cost of Decking Per m2?

Cutting down on the cost of decking can be done in a myriad of ways, with saving on the cost per square meter being the ultimate goal. From strategic cost-cutting to shrewd bargain-hunting, there are various tactics you can employ, including the following:

Choosing a Less Expensive Decking Material

Decking materials come in a wide range of prices, depending on the type of material used. For example, softwood is generally less expensive than hardwood or composite, which can be helpful for those on a tight budget. To keep costs down, it may be worth considering more inexpensive options when choosing your decking materials. Ultimately, this could help to save you money in the long run, as it can help to lower your total costs per square meter.

Installing the Decking Yourself

If you’re looking for ways to save some cash on decking per m2, embarking on a DIY installation journey could be a viable option for you. Of course, this primarily depends on whether you possess the skills and tools necessary to pull it off without a hitch. That being said, tackling a project like this on your own can be pretty laborious and time-consuming, potentially leading to costly mistakes down the road. In this case, hiring professional installation services can help put your mind at ease and ensure that the job gets done right the first time.

Choosing a Simpler Design with Fewer Features or Accessories

The more complex your decking design, the more expensive it will be. Choosing a simpler design with fewer features or accessories can help decrease the cost per m2. For example, consider a basic rectangular shape with simple railings instead of a more intricate design with multiple levels and built-in seating.

While saving money is key, ensuring you’re investing in high-quality decking that will stand the test of time is just as essential. Do your research carefully before selecting a supplier or contractor who offers quality service at a price you can afford.
