Green Garden manages commercial cleaning contracts for offices, retail units, medical premises, schools and industrial facilities across Singapore. Every contract is built from a physical site survey, priced line by line, and monitored through a digital inspection system you can see.
Most cleaning companies in Singapore refuse to publish numbers. Here are ours, so you can budget before you speak to anyone.
| Contract size | Typical scope | Indicative monthly cost |
|---|---|---|
| Small office — up to 1,000 sq ft, 3 sessions/week | One cleaner, 2–3 hour shift. Bin removal, workstation dusting, floor vacuuming and mopping, pantry and washroom wipe-down, consumable replenishment. | S$500 – S$900 |
| Mid-sized office — 1,001–5,000 sq ft, daily | Dedicated team (typically 2 cleaners × 4 hours). Full high-touch disinfection, meeting room reset, supervisory check, monthly digital report. | S$1,800 – S$3,500 |
| Large or multi-site | Full-time on-site supervisor, dedicated account manager, customised programme. | Quoted after a productivity study and site survey |
These are guide figures. Your actual quote depends on net cleanable area, floor finishes, washroom count, headcount and operating hours — which is exactly why we survey the site before pricing it.
All quotes are compliant with the Progressive Wage Model for the cleaning sector, and include CPF contributions, annual leave and overtime rates. A quote that undercuts PWM is either under-declaring manpower or providing no supervision.
Need cleaners under your own supervision rather than a managed programme? See janitorial cleaning services or engage us as a cleaning contractor.
The difference between cleaning providers is rarely the equipment. It is the management system that operates the service day after day. Ours runs in seven phases.
A supervisor or operations manager walks your premises in person and records gross floor area and net cleanable area, the floor-finish schedule and its condition, washroom count and fixture types, workstation and meeting-room counts, a high-touch point inventory, peak occupancy and footfall patterns, and any sensitive areas needing special protocols.
The site survey becomes a granular Scope of Work (SOW). Not “clean office”, but: vacuum all carpeted areas using HEPA-filtered uprights including edges and under accessible desks; empty 87 workstation bins and replace liners; wipe 12 meeting-room glass panels with microfibre and non-streak cleaner. Every task is specific and measurable.
We calculate required man-hours from SOW task durations against productivity benchmarks. This is what tells you why the recommendation is two cleaners for four hours rather than one cleaner for eight — and lets you check our maths against any other quote.
The SOW is digitised into a mobile checklist your cleaners work from on a company device. It dictates task sequence, chemical, and equipment per zone. Nothing runs on memory or informal routine.
A site supervisor verifies checklist completion with photo evidence. A dashboard shows real-time completion rates. You receive scheduled monthly compliance reports. When a task is missed it is flagged, escalated and rescheduled — a closed loop, not a promise.
A formal operations review where SOW adjustments are documented, new requirements assessed and performance trends discussed. You get a named account manager as a single point of contact.
Every 6–12 months we re-walk the site to account for layout changes, new equipment or shifting occupancy, and re-tune manpower and schedules so you are neither over- nor under-serviced.
A fixed schedule fails in Singapore’s humidity and occupancy density. We match frequency to the soil load of each zone.
| Zone / activity | Why | Standard frequency | Adjust when |
|---|---|---|---|
| Washroom full service | Biofilm and odour control; highest risk | Twice daily, plus high-touch disinfection every 2–4 hours in business hours | Increase to 3× daily above 100 headcount per shift or in flu season |
| Workstation bin removal | Pest, odour and insect prevention | Daily | Evening-only where no food waste is present |
| Hard floor vacuum and mop | Grit and dust from footfall | Daily | Second pass during heavy rain or after events |
| Carpet vacuuming | Mite and allergen control | Daily on high-traffic lanes, 3×/week elsewhere | Entrances and corridors always daily |
| High-touch disinfection | Fomite transmission control | Daily | 2–3× daily during outbreak alerts |
| Skirting, partitions, high-level dusting | Aesthetics and air quality | Weekly | Bi-weekly if the office is not externally vented |
| Carpet hot-water extraction | Embedded soil, stains, allergens | Quarterly | Monthly for entrance matting; biannually for executive offices |
| AC filter cleaning | Airflow, efficiency, mould prevention | Monthly check, clean or replace every 1–3 months | Monthly replacement for food courts, ground floor, haze-affected sites |
HEPA-filtered vacuum systems. Commercial-grade canister and upright units with HEPA filtration rated to 99.97% at 0.3 microns, capturing fine dust and allergens rather than re-exhausting them into your breathing zone. Motorised brush heads for carpet, dedicated smooth-floor heads for hard surfaces.
Differential microfibre system. High-density short-pile cloths for disinfection, looped-pile for general dusting. Flat-mop systems with correctly dosed solution per area — no dirty mop water moved from room to room.
Controlled chemical management. NEA-approved disinfectants, diluted through a proportioning system rather than mixed by hand. Safety Data Sheets held on site and available digitally.
Colour-coded equipment, extended to handles, cloths and caddies:
Offices and corporate workplaces. Cleaning timed around sensitive paperwork, care for expensive furniture finishes, quiet operation during working hours, hot-desk reset protocols, and meeting rooms left guest-ready.
Retail. Constant footfall dragging in dirt and moisture. Walk-off mat supply and cleaning, daytime spot-cleaning porters, after-hours hard-floor scrubbing, anti-static treatment on storefront glass.
Restaurants and cafés. Scope designed around your HACCP plan where applicable. Separate colour-coded equipment for kitchen and dining. Dedicated food-area-trained teams working after close and finishing before prep — never an office janitor redeployed into a kitchen.
Healthcare and medical premises. Cleanest-to-dirtiest, high-to-low sequencing. Distinct terminal cleaning SOPs for infectious areas. Teams trained in PPE donning and doffing and NEA-compliant biomedical waste handling.
Industrial and technology facilities. Non-slip treatments, explosion-proof vacuums where required, lock-out tag-out awareness, and WSH training for confined spaces and work at height.
Schools and educational facilities. Tight windows between classes. Low-VOC and fragrance-free chemicals stored in locked cabinets. Daily disinfection of desks, taps, handrails and shared equipment with food-surface-safe sanitiser.
Professional Services Firm, CBD
4,800 sq ft · 60 staff · Contract since April 2024
The client wanted more consistent cleaning across its office, particularly meeting rooms, pantries and washrooms. Green Garden deployed 2 cleaners for 4 hours daily, supported by a customised checklist and digital inspections. The schedule was arranged after office hours to minimise disruption. Routine cleaning covered workstations, floors, common areas and washrooms, with periodic carpet and glass cleaning. After implementation, the client reported fewer cleaning complaints and renewed the contract for another year.
Fashion Retailer, Orchard
3,200 sq ft · 18 staff · Contract since January 2025
The retailer needed cleaning that could fit around customer traffic and daily store operations. Green Garden assigned 1 cleaner for 4 hours daily, with cleaning scheduled before opening and during quieter periods. The scope covered entrance areas, floors, display zones, staff areas and washrooms. Periodic machine scrubbing was added for high-traffic flooring. The structured schedule helped the store maintain a consistently presentable environment without interfering with customer operations.
Private Medical Clinic, East Singapore
3,900 sq ft · 32 staff · Contract since June 2024
The clinic required a structured cleaning programme covering consultation rooms, reception, washrooms, staff areas and frequently touched surfaces. Green Garden deployed 2 WSQ-trained cleaners for 4 hours daily, using colour-coded cleaning tools and a customised checklist. Digital inspection records were used to monitor completed tasks. Cleaning was scheduled around clinic operations to minimise disruption to patients and staff. The client subsequently extended the cleaning scope to include periodic deep cleaning and disinfection.
Technology Facility, West Singapore
12,000 sq ft · 85 staff · Contract since February 2025
The client required a cleaning programme suited to a larger technology facility rather than a conventional office. Green Garden deployed 3 cleaners for 6 hours daily, covering offices, common areas, washrooms and designated operational spaces. HEPA vacuums, microfiber mops and colour-coded tools were incorporated into the cleaning programme. The team worked around facility operations and access requirements. Digital inspections provided management with records of completed cleaning tasks and areas requiring follow-up.
Private Education Centre, Singapore
8,500 sq ft · 45 staff · Contract since August 2024
The education centre needed regular cleaning across classrooms, offices, washrooms, corridors and shared spaces while operating around student schedules. Green Garden assigned 2 cleaners for 5 hours daily, with additional periodic cleaning during quieter periods. The programme included floor cleaning, waste removal, washroom maintenance and high-touch surface cleaning. A customised checklist helped organise recurring tasks across the facility. The client later added periodic carpet cleaning and machine scrubbing to the existing contract.
NEA licence. Every cleaning business in Singapore must be licensed under the Environmental Public Health Act. The grade matters — it reflects compliance record, financial standing and operational capability. Ask any provider what class they hold.
ISO 9001:2015. Documented, auditable processes from cleaner deployment through complaint handling. Ask to see the certification scope and the date of the last surveillance audit.
bizSAFE Star. The highest bizSAFE level, meaning risk management and Workplace Safety & Health practices are integrated into operations. We can share a site-specific Risk Assessment and Safe Work Procedure on request.
WSQ-trained cleaners. We maintain training logs covering chemical handling, infection control and technique, with regular refresher courses — not a one-off generic certificate.
Insurance. Public Liability and Work Injury Compensation certificates provided on request, naming your site or carrying a broad-form clause.
The most common procurement mistake is comparing two quotes 30% apart in price that are in fact 30% apart in scope. To compare fairly, issue every bidder the same RFQ table: task area, frequency, specification, expected duration per visit, and consumables included with grade and refill frequency.
A quotation should break out base cleaning labour, supervision and management cost, equipment, the consumables package with per-item costs, ad-hoc service rates, any mobilisation fee, and public holiday and weekend surcharges — each as a separate line.
Then ask every shortlisted provider these questions:
We answer all seventeen in writing. If a provider cannot, they are not a serious contender.
Office expansion. We survey the new unit within 48 hours, propose an SOW addendum with revised manpower, and give you a transparent cost adjustment before the next cycle — no waiting for renewal.
Events. Book an event support package by email: a cleaner pre-event to set up and wipe down, and one post-event to clear catering waste, vacuum and reset the room.
Outbreak response. One phone call activates a terminal clean of the affected zone using a virucidal disinfectant with documented dwell time, plus a follow-up clean the next day.
Staffing cover. If your assigned cleaner is on medical leave, a replacement from our float pool is on site for the next scheduled shift, with a handover document covering your site’s specifics.
How much do commercial cleaning services cost in Singapore? Small offices up to 1,000 sq ft on three sessions a week typically run S$500–S$900 per month. Mid-sized offices of 1,001–5,000 sq ft on daily service typically run S$1,800–S$3,500. Larger and multi-site contracts are quoted after a site survey. Cost is driven by net cleanable area, floor finishes, washroom count, headcount and hours.
Are you NEA-licensed? Yes. Green Garden holds a current NEA cleaning business licence under the Environmental Public Health Act, along with ISO 9001:2015 certification and bizSAFE Star. Certificates are provided on request.
Can you clean outside office hours? Yes. Most of our office contracts run evening shifts, typically 6pm to 10pm. F&B contracts usually run after kitchen close and finish before prep. Weekend, public holiday and overnight scheduling is available, with surcharges stated up front in the quotation.
What is the minimum contract period? We offer both ongoing contracts and one-off deep cleans. Ongoing contracts include a formal review at 6–12 months where scope and manpower are re-optimised.
Do you supply consumables? Yes — bin liners, hand soap, toilet paper and paper towels can be included. The package is itemised with per-unit costs and refill frequency so you can see exactly what you are paying for, or exclude it and supply your own.
Do you use eco-friendly products? We use low-VOC and certified products wherever the application allows, with water-efficient methods and waste segregation support. For schools and childcare we default to fragrance-free, non-toxic, food-surface-safe sanitisers.
What happens if cleaning quality drops? Every task is verified against a digital checklist with photo evidence. A missed task is flagged by the supervisor, escalated, and rescheduled within the agreed window. Persistent issues go to your named account manager and are documented at the monthly review.
We will walk your premises, record the detail, and return a fully itemised scope of work and quotation — no obligation, no pressure.
