Office cleaning costs in Hong Kong vary significantly depending on the size and type of premises, the frequency and scope of services required, and the operational standards of the contractor. This guide provides a transparent framework for understanding what drives cleaning costs and how to evaluate competing proposals on a like-for-like basis.
Daily Maintenance Cleaning
Daily maintenance cleaning — the routine cleaning of workstations, communal areas, kitchens, washrooms, and lobbies — is typically priced on a per-square-foot per-month basis or as a fixed monthly retainer. For a standard Grade A office in Hong Kong, expect to budget in the range of HK$1.50 to HK$3.50 per square foot per month for daily maintenance, depending on the cleaning frequency (once daily, twice daily, or continuous daytime service), the number of washrooms relative to floor area, and whether the contract includes consumables such as soap, paper towels, and bin liners.
A 5,000 sq ft office with once-daily cleaning and standard consumables would typically fall in the range of HK$8,000 to HK$18,000 per month. Offices with high footfall, open-plan layouts with extensive communal areas, or premium finishes requiring specialist care will sit at the upper end of this range.
Deep Cleaning
Periodic deep cleaning — typically conducted quarterly or semi-annually — covers areas not addressed in daily maintenance: behind and beneath furniture, air conditioning units, ceiling vents, partition tracks, and hard-to-reach surfaces. Deep cleaning is usually priced as a one-off assignment rather than included in the monthly retainer.
For a 5,000 sq ft office, a comprehensive deep clean typically costs between HK$3,500 and HK$8,000 depending on the condition of the premises, the number of workstations, and whether specialist treatments such as upholstery shampooing or hard floor stripping are included.
Carpet Cleaning
Commercial carpet cleaning in Hong Kong is priced per square foot of carpeted area. Hot water extraction (the most effective method for commercial carpets) typically costs HK$0.80 to HK$1.80 per sq ft. Encapsulation cleaning — faster drying, suitable for high-traffic areas that cannot be closed for extended periods — is generally slightly cheaper. Annual carpet maintenance programmes combining encapsulation cleaning (quarterly) with hot water extraction (annually) offer the best balance of cost and carpet longevity.
HVAC and Air Duct Cleaning
HVAC cleaning costs depend on the number and type of fan coil units (FCUs), the length and configuration of ductwork, and whether the system requires chemical treatment for mould or bacterial contamination. A typical office floor with 10 to 20 FCUs and associated ductwork can expect to pay HK$5,000 to HK$15,000 for a full HVAC clean, with larger or more complex systems costing proportionally more.
What Drives Price Variation
The most significant cost driver in Hong Kong's cleaning market is labour. Cleaning operatives are paid at or above the statutory minimum wage (currently HK$40 per hour), and contractors with higher training standards, lower staff turnover, and better supervision ratios will have higher labour costs — which should be reflected in their pricing. Unusually low quotes frequently indicate underpayment of staff, inadequate supervision, or the substitution of lower-quality chemicals and equipment.
Other key cost drivers include access requirements (high-rise facade cleaning requires rope access or gondola equipment), specialist certification requirements (data centre cleaning requires ESD-safe protocols and security clearances), and the frequency and timing of service (overnight or weekend cleaning commands a premium over standard business-hours service).
Evaluating Proposals
When comparing cleaning proposals, request a detailed scope of works that specifies the tasks to be performed at each visit, the cleaning chemicals and equipment to be used, the supervision ratio (how many operatives per supervisor), and the contractor's quality assurance process. A proposal that simply states "daily office cleaning" without specifying tasks, frequencies, and standards is not comparable to one that provides a detailed cleaning specification.
Ask for evidence of quality management documentation, public liability insurance (minimum HK$10 million), and employer's liability insurance. ISO 9001 certification is a positive indicator of operational maturity, but the absence of formal certification does not preclude a well-run contractor — request their quality assurance documentation and assess it on its merits. Request references from current clients in comparable premises and, where possible, arrange a site visit to a reference property before awarding the contract.
