Key takeaways
- Most concrete work jobs in Hong Kong land between HK$2,000–HK$80,000 — known locally as concrete spalling repair and screeding.
- Concrete spalling repair is one of Hong Kong's most common building works due to the ageing concrete stock; works may fall under the Minor Works Control System and structural repairs require registered contractors under the Buildings Ordinance. Mandatory Building Inspection Scheme notices often drive these repairs.

What affects the price
- Job size and scope — bigger or more complex jobs move you up the ranges above.
- Access and condition — hard-to-reach areas, older properties or neglected maintenance add labour time.
- Materials and quality level — where materials are involved, the grade you choose often matters more than labour.
- Urgency — same-day or out-of-hours work usually carries a premium.
- Where you live — large metros in Hong Kong typically run above the national range; smaller towns below it.
How to save
- Get at least three quotes and compare like-for-like scopes, not just totals.
- Be flexible on timing — off-peak slots are often cheaper.
- Bundle related tasks into one visit to spread call-out costs.
- Agree the scope in writing up front to avoid change-order surprises.
How to hire a concrete work pro in Hong Kong
- For structural repairs, use a Buildings Department Registered General Building Contractor or Registered Minor Works Contractor as the works class requires
- For spalling (very common in older buildings), confirm the repair includes treating corroded rebar and a bonding agent
- Get scope, area and material spec in a written quote
- Check whether the building's management or an MWCS submission is needed
- Confirm debris disposal — charged at government facilities
- Ask for photos of completed repairs in similar buildings
Red flags
- Cosmetic plaster patch offered over exposed rusty rebar
- Structural work by an unregistered contractor
- No written scope
- Full payment upfront

Frequently asked questions
What should a concreting quote include?
Excavation and sub-base, formwork, reinforcement (mesh size or fibre dose), concrete grade and thickness, the finish (broom, trowel, exposed aggregate, stamped), control joints, curing method, and spoil removal. Any quote that just says 'supply and lay concrete' leaves too much undefined.
What finishes can concrete have?
Broom (non-slip, standard outdoors), steel trowel (smooth, indoor), exposed aggregate, stamped/patterned, coloured and polished. Decorative finishes can add 30-100% to the base rate but replace the cost of a separate surface like pavers or tiles.
Does weather affect concrete pouring?
Strongly. Frost can ruin an uncured pour, extreme heat causes plastic shrinkage cracking, and rain marks fresh surfaces. Good contractors watch forecasts and will delay a pour; be suspicious of anyone happy to pour into bad weather to keep the schedule.
How much does concrete work cost?
Concrete is priced by area and thickness for slabs (per m² or sq ft), by volume for supply (per cubic metre/yard), and by the job for repairs. The concrete itself is often less than half the bill — formwork, reinforcement, sub-base preparation, finishing and access drive the labour cost.
How thick should a concrete slab be?
Common rules of thumb: 75-100mm (3-4") for paths and patios, 100-125mm (4-5") for driveways and garage floors, more for heavy vehicles — always over a compacted sub-base with mesh or fibre reinforcement. Thin slabs on soft ground crack no matter how good the finish looks.
How long does concrete take to cure?
You can usually walk on it after 24-48 hours, drive on it after about 7 days, and it reaches design strength at 28 days. Curing (keeping it damp, protecting from frost or extreme heat) in the first week matters more for durability than almost anything else.
Why is spalling repair such a big deal in Hong Kong?
Decades-old reinforced concrete plus humid, salty air corrodes rebar, which expands and pops the cover concrete. Proper repair means breaking out to sound concrete, treating the steel, and rebuilding with repair mortar — patching over it just delays the next fall of concrete.
