Decking FAQs
Which timber is best for decking?
Which timber is best for a project is wholly dependent on your clients lifestyle and needs. While Ironbark hardwood is a popular choice due to its strength and longevity and merbau is a favourite for its cost effectivness, hardwood timber does require regular maintenance. Clients with mobility issues, busy schedules or young children may prefer composite decking boards which tend to be lower maintenance and will not splinter.
What size timber should I use for decking frame?
The size of the timber you should use for your decking frame will vary. Factors that may influence this include:
- Size and weight of the decking boards
- What kind of furniture or equipment your customer will be storing on the deck
Contact the decking experts at Dahlsens for advice tailored to your project.
What is the life expectancy of a wood deck?
The average lifespan of a timber deck is around 10 to 15 years. The actual longevity of a deck is highly dependent on the type of timber, location, proximity to water, techniques used during the installation process, and the maintenance it receives. With proper care, a high quality timber deck can last up to 40 years or more.
What is the best low maintenance deck material?
Composite decking is typically made from wood fibres and recycled plastic. It is a great, low maintenance option for the average homeowner. Composite decking boards require very little cleaning or maintenance and do not splinter, warp or crack.
What is composite decking?
Composite decking is made from a blend of recycled wood fibres and high-density polyethylene (HDPE), though the exact mix can vary by manufacturer. The primary components include wood fibres, often reclaimed from sawmill by-products, which provide strength and texture, and HDPE plastic, which binds with the wood to enhance durability, moisture resistance, and UV protection. Some manufacturers also add materials like fibreglass or rice hulls to improve flexibility, strength, or fire resistance, and anti-UV additives, which are essential in high sun-exposure areas to reduce fading. The specific ratio of wood to plastic may differ based on the desired performance characteristics, but overall, composite decking is designed to be a low-maintenance, long-lasting alternative to traditional wood decking.
How to clean composite decking?
Cleaning composite decking is an important part of its maintenance to ensure it lasts longer and maintains its appearance. To clean composite decking, start by removing any loose dirt, leaves, and debris with a broom or leaf blower. Rinse the surface with a garden hose to loosen remaining dirt—avoid high-pressure washers as they can damage the deck. Prepare a mild cleaning solution using dish soap or a composite deck cleaner, avoiding harsh chemicals like bleach. Gently scrub the deck with a soft-bristle brush or sponge, focusing on any stains or mildew spots. Rinse thoroughly to remove all soap residue, as leftover soap can attract more dirt. Let the deck air dry completely before placing furniture back to prevent mould and mildew. For tougher stains like grease, use a degreaser specifically formulated for composite decking. Regular cleaning helps maintain the deck’s appearance and prolongs its lifespan.
