Deck Building & Repair in Gauteng

If the frame (joists, bearers, posts) is sound, boards and balustrades can be replaced individually and the structure re-stained for a fraction of a rebuild. If posts are rotting at the base or the ledger connection to the house is corroded, replacement is usually safer and not much more expensive than piecemeal repair.

A simple ground-level deck takes 2-4 days. An elevated deck with footings, stairs and balustrades typically takes 1-2 weeks, plus any permit or inspection lead time before work can start.

Timber is cheaper to install but needs sanding, staining or oiling every 1-3 years. Composite costs 50-100% more upfront but only needs washing. Over 10-15 years the totals often converge, so the decision usually comes down to upfront budget and how much maintenance you will actually do.

Deck cost is driven by area, height off the ground, and material. Ground-level softwood decks are the cheapest; elevated decks need engineered footings and balustrades, and composite or hardwood boards can double the board cost. Most quotes are priced per square metre or square foot, with stairs, balustrades and lighting as line items.

The most common residential decks fall between 12-25 m² (130-270 sq ft) — enough for a table, chairs and a grill. Costs do not scale perfectly with area: small decks carry fixed costs (access, footings, delivery), so price per square metre drops as size grows.

A complete quote lists demolition/removal of any old structure, footings, framing timber and spans, board type and grade, fixings (hidden vs face-screwed), balustrades, stairs, waste removal, and whether permit fees and engineering are included. Missing line items are where cheap quotes grow.

CCA-treated pine is roughly half the price of Balau but needs sealing every year and dents easily. Balau and composite dominate coastal and high-end work. Expect installed rates of roughly R1,200-2,500 per m² depending on the board.
