How to hire a deck building & repair pro in Hong Kong
- Check with building management and the Deed of Mutual Covenant before decking a balcony, podium or rooftop
- Confirm the work does not count as unauthorised building works (UBW) — fixed structures on rooftops are a Buildings Department enforcement target
- Choose composite or hardwood rated for typhoon-season rain and intense sun
- Ask for a corrosion-resistant sub-frame (aluminium or stainless) — coastal humidity destroys mild steel
- Get a written quote in per-square-foot terms with brand and board spec
- Agree that decking must not block roof drainage outlets
Frequently asked questions
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.
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.
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.
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 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.
Can I deck my Hong Kong rooftop?
Loose-laid or interlocking deck tiles are generally acceptable as a floor finish; fixed pergolas or raised platforms can be treated as unauthorised building works. Check with your management office first, and keep drainage outlets and waterproofing membranes untouched.
