Decking Adelaide — Timber & Composite Deck Builders
Beautiful, durable decking – tailored to your home and lifestyle.
Custom Timber Decking Adelaide
Timber and composite decking in Adelaide costs approximately $200–$450 per square metre fully installed, depending on materials, deck height, and site conditions. SA Quality Home Improvements installs both treated hardwood timber decking and low-maintenance composite decking suited to Adelaide’s climate. Composite decking requires less maintenance than timber and does not warp, splinter, or fade, though it carries a higher upfront cost. Building approval is required for elevated decks or larger structures — SAQHI handles all permits.
SAQHI builds decks across Adelaide with sub-frames available in Colorbond® steel, timber or Zincalume, and decking boards in a wide range of quality timbers and composite materials. Whether it’s a standalone deck or the perfect complement to your existing Colorbond® steel verandah or pergola, our decks are built to the same exacting standard as the structures we’re known for across Adelaide.

- Trex® Decking comes with a 25-year fade and stain limited warranty
- We take care of the supply and the installation
Decking Boards & Colorbond® Sub-Frames to Complement Your Outdoor Area
Many Adelaide homeowners pair a SAQHI deck with their Colorbond® verandah or pergola — the contrast of warm timber or composite boards against a crisp Monument® or Surfmist® steel roof is a classic combination. Our Colorbond® steel sub-frames mean the structure underneath is just as durable as the deck looks above it. SAQHI can design and build both, giving you a seamless, finished result from one trusted team.

What Our Customers Are Saying
Frequently Asked Questions
Timber decking offers a natural look and feel, while composite decking (like Trex®) provides the appearance of timber but with less maintenance. Timber may require regular staining or sealing, whereas composite is designed to resist fading, mould, and scratches.
Composite decking has a higher upfront cost, but it often works out cheaper in the long run due to lower maintenance costs and longer lifespan.
Yes! Both timber and Trex® decking come in a range of finishes and colours. Timber offers a natural grain variation, while Trex® has luxury colours designed to suit any style of home.
With the right care, timber decks can last 10–15 years. Trex® composite decking, thanks to its protective shell, often lasts much longer and comes with a 25-Year Limited Residential Fade & Stain Warranty.
Yes. Trex® is made from 95% recycled materials, using reclaimed timber and plastic film. It’s a sustainable alternative to traditional decking.
Deck prices depend on size, decking boards, frame type, height and site conditions. Timber decking is usually cheaper upfront than composite, while composite needs far less maintenance over time. Book a free measure and quote for an accurate price on your deck.
