How to hire a deck building & repair pro in Singapore
- For condos, get management (MCST) approval before any balcony decking work; for HDB flats check HDB renovation guidelines
- Choose between chengal (traditional hardwood), composite (WPC) and aluminium-composite decking — maintenance differs sharply in the tropical climate
- Confirm the sub-frame material: aluminium or treated hardwood battens, not mild steel that rusts
- Ask whether the quote is per square foot supplied-and-installed, and what plot thickness/brand of composite is used
- Check the installer's track record with your property type (balcony vs landed garden vs roof terrace)
- Agree on drainage — decking must not block balcony scuppers or floor traps
Frequently asked questions
What deck size do most homeowners build?
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.
Composite vs timber decking — which is cheaper long-term?
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.
Can an old deck be repaired instead of replaced?
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.
What should a deck quote include?
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.
How much does it cost to build a deck?
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.
How long does a deck build take?
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.
How often should a timber deck be stained or oiled?
Every 12-24 months for oil finishes and 2-4 years for film-forming stains, depending on sun exposure. Re-coating on schedule is the single biggest factor in how long the boards last.
Chengal or composite decking in Singapore?
Chengal is the classic tropical hardwood — dense, durable, but needs periodic oiling and grows a silver patina. Composite needs almost no maintenance and resists the constant humidity, which is why most new balcony jobs now spec WPC or mineral-composite boards at similar or lower installed cost.
