The Complete Guide to Decking: Everything You Need to Know to DIY the Perfect Outdoor Space
Decking is a fantastic way to transform your outdoor living area into a functional, beautiful space for entertaining or relaxing. Whether you’re a DIY enthusiast or planning to hire a professional, building a deck requires some careful planning and the right materials. At Geographe Timber & Hardware, we have everything you need—from decking timber like Merbau and Jarrah to composite decking and all the screws, stains, and tools to complete the job.
Decking vs. Paving: What option is better?
Decking, particularly when using sustainably sourced timber or eco-friendly composite materials, can be more environmentally friendly than paving. Here’s why:
- Sustainable Timber: Timber decking made from sustainably harvested wood, such as FSC-certified Pine or Jarrah, is a renewable resource. As trees grow, they absorb carbon dioxide, making timber a lower-carbon choice compared to paving materials like concrete or stone, which require energy-intensive manufacturing processes.
- Composite Decking: Composite is often made from recycled wood fibres and plastic, reducing the need for virgin materials and diverting waste from landfills. It also requires less maintenance, meaning fewer chemical treatments and coatings are needed over its lifetime compared to traditional timber or concrete.
- Less Heat Absorption: Decking, especially timber, absorbs less heat than concrete or stone paving, which tends to retain and radiate heat during summer. This means your deck stays cooler to walk on and can help reduce the overall temperature around your house, leading to a more comfortable outdoor space and potentially lowering cooling costs inside.
Can Decking Keep Your House Cooler in Summer?
Yes, decking can help keep your house cooler, especially compared to paving. Here’s how:
- Reduced Heat Retention: Timber decking doesn’t trap and hold heat like concrete or stone paving, which can absorb the sun’s rays and radiate heat long after sunset. This helps maintain a cooler environment around your home during hot summer days.
- Ventilation: Decking allows for air circulation underneath, which can help dissipate heat and create a cooler microclimate around your outdoor living space. In contrast, paving sits directly on the ground, trapping heat and contributing to a warmer surface area.
By choosing the right deck, especially eco-friendly options, you’re making a sustainable choice while creating a cooler, more comfortable outdoor area around your home.

Hot Tip: One of the best ways to keep your home cooler during summer is by surrounding it with a lush, healthy green lawn. Check out our blog for tips on reviving your lawn and keeping it green through the summer heat.
Did you know studies show that grass surfaces can be significantly cooler than hard surfaces like concrete or asphalt. A lawn can be up to 15°C cooler than bare soil and 30°C cooler than asphalt or concrete on a hot summer day. Even better 50-square-metre of lawn can produce enough oxygen to meet the daily needs of a family of four.
Choosing the Right Material
One of the most important decisions you’ll make when building your deck is selecting the right material. Here are the key options available at Geographe Timber & Hardware:
1. Merbau
Merbau is a popular hardwood that’s not only aesthetically pleasing but also incredibly durable. Its natural resistance to rot and pests makes it ideal for outdoor decking in Busselton’s coastal environment.
2. Jarrah
Known for its rich red-brown colour, Jarrah is another hardwood option that offers great durability. It’s particularly suitable for areas with high foot traffic, and it weathers beautifully over time.
3. Pine
Pine is a cost-effective option for those on a budget. It’s lightweight, easy to work with, and when treated, it resists decay and pests. However, it may require more regular maintenance than hardwoods.
4. Composite Decking
For those looking for a low-maintenance solution, composite decking is a great option. It’s made from a combination of wood fibres and plastic, offering durability and resistance to weather without the need for staining or sealing.
Decking Accessories: Screws, Stains, and More are available at our hardware store.
To ensure your deck lasts for years, it’s essential to use the right fasteners and finishes.
1. Decking Screws & Fasteners
Always opt for stainless steel or galvanised screws. These screws resist corrosion, ensuring your deck remains sturdy, even in Busselton’s coastal conditions.
2. Decking Stain or Oil
To protect your timber deck, apply a stain or decking oil. A quality stain will not only protect your deck from the elements but also enhance the natural beauty of the wood. Choose from a range of colours to complement your outdoor aesthetic.
Checklist of Tools You’ll Need
Before you start, make sure you have all the essential tools and materials on hand. Here’s a quick checklist to ensure you’re fully prepared.
- ✅ Tape measure – for accurate measurements
- ✅ Spirit level – to ensure your deck is even
- ✅ Cordless drill/impact driver – for driving screws
- ✅ Decking screws – stainless steel or galvanised for weather resistance
- ✅ Hammer – for securing nails and driving in stakes
- ✅ Rubber mallet – useful for adjusting decking boards without damaging them
- ✅ Carpenter’s pencil – to mark measurements and cuts
- ✅ Shovel and post hole digger – if installing stumps for a raised deck
- ✅ Work gloves and safety goggles – to protect yourself during the build
- ✅ Stain or decking oil – for finishing the deck
Now that you’re fully equipped, let’s dive into the step-by-step guide to building your deck.
Step-by-Step Guide to Building Your Deck
1. Get the Right Permits
Before starting your project, check with your local council to see if you need a permit. In Busselton and surrounding areas, most decks require approval, especially if they are elevated.
2. Plan Your Layout
Consider the size, shape, and height of your deck. Will it be level with your back door, or do you need to build steps? Also, think about any additional features like seating or planters.
3. Prepare the Ground
Your deck can be built on various surfaces like soil, grass, or concrete. If you’re building on soil, make sure to check for any underground pipes before digging.
4. Install the Frame
Use treated timber for the frame to ensure longevity. The joists should be spaced appropriately (no more than 450mm apart) to provide a sturdy base for your decking boards.
5. Lay the Decking Boards
Depending on your material choice, you can either screw or clip your boards into place. Ensure there is sufficient spacing between the boards for water drainage and airflow.
6. Finishing Touches
Once the boards are in place, you can sand the deck for a smooth finish and then apply a decking stain or oil to protect it from the weather.
Timber vs. Composite Decking: Which One Should You Choose?
When deciding between timber and composite decking, consider factors like maintenance, appearance, and budget. Timber decks, such as Merbau or Jarrah, offer a natural look and feel, but it requires regular staining and maintenance. Composite deck options, on the other hand, is virtually maintenance-free and highly durable but comes at a higher upfront cost.
Decking Ideas to Elevate Your Outdoor Space
- Multi-level decks: Create zones for dining and relaxing by incorporating different levels.
- Built-in seating: Save space and add functionality with built-in benches.
- Planter boxes: Add greenery with integrated planter boxes to soften the look of your deck.
- Lighting: Incorporate solar or LED lighting to make your deck usable at night.
