A treated pine deck lasts 15 to 20 years with regular maintenance (resealing every 2 to 3 years). Hardwood decks – Balau, Garapa, and Massaranduba – last 25 to 30 years with periodic oiling. Cape Town’s coastal climate demands quality timber and proper treatment to maximise lifespan. The substructure quality and installation workmanship are equally important. A well-built hardwood deck can outlast the home it’s attached to.
The best wood depends on your budget and priorities. For affordability, treated pine offers excellent value at R1,700 to R2,200 per m² installed. For durability and low maintenance, Balau and Garapa are the top choices in Cape Town – both resist moisture, insects, and weathering exceptionally well. Garapa offers a golden tone while Balau provides a richer reddish-brown colour. Read more about decking wood prices in South Africa and explore our wooden decking options.
Not necessarily. Entry-level composite decking starts around R1,800 per m² – similar to treated pine. Premium composite ranges up to R4,500 per m². The advantage of composite is near-zero maintenance, which can make it cheaper over 15 to 20 years. However, timber offers natural warmth, can be refinished, and often costs less upfront. Compare both options with our composite decking range or get a quote for both materials.
Timber decking prices in Cape Town range from R1,700 to R3,500 per m² fully installed in 2026. Treated pine sits at the lower end (R1,700 – R2,200 per m²), while premium hardwoods like Balau and Garapa range from R2,800 to R3,500 per m². These prices include materials, substructure, and labour. Extras like balustrades, stairs, and sealing are additional. Contact us for a free quote to get an accurate price for your property.
It depends on the size, height, and location of your deck. The City of Cape Town may require building plan submissions for elevated decks, large structures, or decks that affect boundary setbacks. Ground-level decks under a certain size may be exempt, but it’s always worth confirming. Cape Decking can handle plan submissions and council approvals on your behalf - just ask when you request your quote.
