Detailed Guide Into What Your Service Agreement Should Actually Include

Commercial window cleaning specifications for Melbourne building managers are rarely given the attention they deserve. When a Melbourne building manager signs a commercial window cleaning contract, they are typically presented with a one-page document listing a price, a visit frequency, and a liability clause. It is signed, filed, and forgotten until something goes wrong — a streaked facade before an important tenancy inspection, a missed visit during peak presentation season, or a WorkSafe incident with no clarity on who was responsible.

The gap between what most commercial window cleaning specifications for Melbourne building managers actually receive and what they should contain is significant. For facilities managers overseeing multi-tenancy commercial buildings, CBD office towers, retail complexes, or industrial properties across Melbourne, a poorly specified service agreement creates operational risk, financial exposure, and persistent presentation problems that reflect directly on asset value.

This guide examines every component a professional set of commercial window cleaning specifications for Melbourne building managers should include — from access methodology and safety compliance documentation to environmental specifications, seasonal scheduling protocols, and performance benchmarks. Understanding these elements before signing puts building managers in a position to hold contractors accountable and protect their assets year-round.

Why Standard Window Cleaning Contracts Fall Short

The commercial window cleaning industry in Melbourne ranges from sole operators with a squeegee and a ladder to fully accredited companies operating rope access systems on 40-storey towers. This wide disparity in capability creates a corresponding range in contract sophistication.

Most residential-style operators carry their terms over into commercial work, resulting in agreements that cover basic liability but ignore the operational complexity of managing a commercial facade programme. These contracts typically fail in five key areas:

Scope ambiguity — “clean all windows” without specifying access methodology, internal versus external surfaces, frames, sills, and associated glazed elements like skylights, atriums, or curtain wall panels.

No performance standards — acceptance criteria are absent, meaning there is no contractual basis for disputing substandard work. What constitutes a clean window? What is the standard for streak-free results on tinted or coated glass?

Inadequate safety documentation — Victorian WorkSafe regulations impose specific obligations on both contractors and building owners. A contract that does not reference the contractor’s Safe Work Method Statements (SWMS), IRATA certifications, or height safety equipment inspection records leaves the building manager with potential co-liability.

No scheduling provisions — Melbourne’s weather variability means that a fixed annual schedule is rarely appropriate. Quality agreements build in weather contingency, seasonal adjustment, and priority response clauses.

Missing post-service accountability — without documented completion records, dispute resolution processes, or rectification timelines, building managers have no mechanism to enforce standards when work does not meet expectations.

The sections below detail precisely what should appear in every set of commercial window cleaning specifications for Melbourne building managers — covering safety obligations, scope clarity, scheduling, and performance accountability.

---

Section 1: Scope of Works — Defining Every Surface

The scope of works section is the foundation of the entire agreement. Vague scope language is the primary source of disputes between building managers and window cleaning contractors — and one of the most common gaps in commercial window cleaning specifications for Melbourne building managers — particularly when buildings contain multiple glazed elements beyond standard windows.

Internal Versus External Cleaning

The agreement must explicitly state whether internal cleaning, external cleaning, or both are included in the quoted price. Many commercial buildings require internal cleaning at different frequencies to external cleaning — a common arrangement is external quarterly with internal twice per year. If this is the case, the agreement should specify each separately with individual pricing.

For high-rise buildings above approximately four storeys, internal cleaning is typically performed by traditional methods from inside the building with standard equipment. External cleaning of upper floors requires rope access, BMU (Building Maintenance Unit) operations, or elevated work platforms. These are fundamentally different services with different safety requirements, and the agreement should acknowledge this distinction.

Glazed Elements Beyond Standard Windows

Melbourne commercial buildings contain a wide variety of glazed surfaces that may or may not fall under a standard window cleaning scope. Each of the following should be explicitly included or excluded in the agreement:

• Curtain wall panels — full-facade glazing systems covering multiple floors
• Skylights and roof glazing — particularly relevant for retail atriums, airport terminals, and commercial spaces with feature roofs
• Entrance canopies — glass or polycarbonate overhead structures at building entries
• Atriums — multi-storey internal glazing requiring specialist access
• Glass balustrades and balustrading — particularly common in modern commercial fitouts
• Shopfront glazing — relevant for retail properties where tenant responsibility may differ from landlord obligation
• Signage surrounds — glazed panels adjacent to illuminated building signage
• Louvres and ventilation panels — glass or metal louvres that accumulate contamination similarly to windows

A properly scoped agreement lists each element by location within the building, with notation of the access method to be used and frequency of service.

Frame, Sill, and Surround Cleaning

Window cleaning that addresses only the glass surface leaves frames, sills, and flashings dirty, creating an inconsistent presentation and allowing contaminant accumulation that eventually migrates back onto the glass. The agreement should specify whether frame wiping, sill cleaning, and surround detailing are included.

For Melbourne buildings in coastal areas — particularly along Port Phillip Bay from Port Melbourne through to Brighton — salt air deposits accumulate heavily on aluminium and powder-coated frames. Scope language should address this, as frame cleaning in these locations requires more frequent attention and different cleaning agents than standard inland commercial properties.

---

Section 2: Access Methodology and Equipment

How a contractor accesses your building’s windows determines safety risk, disruption to building occupants, cost structure, and the quality of the result. The service agreement must document the specific access methodology for every part of the building.

Ground-Level and Low-Rise Access

For building sections accessible from ground level or via standard extension ladders and water-fed poles, the agreement should specify:

• Maximum working height under this methodology
• Equipment type (traditional squeegee, water-fed pole system, or both)
• Pure water filtration specification for water-fed pole work — Melbourne’s hard water supply means that untreated tap water will leave mineral deposits on glass, so reputable contractors use deionised or reverse osmosis water
• Proximity to public areas and pedestrian management requirements

Elevated Work Platforms

Where scissor lifts, boom lifts, or spider lifts are required, the agreement should address:

• Equipment type and maximum working height
• Operator licence certification requirements (EWP licence)
• Site-specific considerations including surface load capacity for vehicle access, underground car park access, and proximity to underground services
• Traffic management requirements for any public areas
• Pre-mobilisation site inspection requirements

For Melbourne CBD buildings, EWP operations typically require council permits for any work encroaching on public footpaths or roads. The agreement should clarify responsibility for permit applications and associated costs.

Rope Access — IRATA Certification Requirements

Rope access is the gold standard for high-rise window cleaning in Melbourne, offering superior flexibility compared to BMU systems and significantly lower cost than scaffolding or full EWP programmes. However, rope access introduces specific technical and safety requirements that must be documented in any service agreement.

The agreement should require, at minimum:

IRATA Level certification — Rope access technicians should hold current IRATA (Industrial Rope Access Trade Association) certification at appropriate levels. Supervisors should hold IRATA Level 3, with operatives holding minimum Level 1 or 2 depending on task complexity. The agreement should require provision of current IRATA certification documentation before commencement of any rope access work.

Rigging point inspection — Anchor points and rigging structures must be inspected and certified before each rope access campaign. The agreement should specify whether the contractor provides this service or whether an independent rigging inspection is required, and document any relevant anchor point inspection history.

Equipment inspection records — Rope access equipment including ropes, harnesses, descenders, and ascenders must be inspected to manufacturer specifications and AS/NZS 4488. The contractor should provide current equipment inspection records on request.

Working at Heights training documentation — All operatives must hold current Working at Heights certification. The agreement should require this documentation be provided before work commences.

Building Maintenance Units

Some Melbourne commercial towers are equipped with BMUs — permanent cradle systems installed by the building. Where BMU operations are involved, the agreement must address:

• BMU operator certification and currency
• Scheduled maintenance requirements for BMU equipment
• Responsibility for BMU servicing and any associated costs
• Contingency access methodology if BMU is unavailable

---

Section 3: Victorian WorkSafe Compliance and Safety Documentation

Victoria has some of Australia’s most stringent height safety regulations, administered through WorkSafe Victoria under the Occupational Health and Safety Act 2004 and the associated OHS Regulations 2017. Building managers who engage window cleaning contractors are not passive bystanders in this regulatory framework — the principal contractor obligations imposed by Victorian law mean that building owners and managers share responsibility for ensuring safe work practices on their properties.

Robust commercial window cleaning specifications for Melbourne building managers must address WorkSafe compliance explicitly, as Victorian law places obligations on both the contractor and the building’s responsible parties.

Safe Work Method Statements

The contractor should provide a current Safe Work Method Statement (SWMS) for all high-risk construction work performed on the property. Under Victorian law, any work at heights above two metres is classified as high-risk construction work requiring a SWMS. The SWMS must:

• Identify the high-risk construction work involved
• Specify the safety measures to be implemented
• Be signed by the contractor before work commences
• Be kept on site during the works

The service agreement should require SWMS provision before initial commencement and updated documentation whenever the scope, access methodology, or equipment changes.

Height Safety Compliance Documentation

Beyond SWMS requirements, the agreement should stipulate that the contractor maintains and can produce on request:

• Current public liability insurance (minimum $20 million for commercial work)
• Workers compensation insurance documentation
• Plant and equipment registration where applicable (EWPs above certain capacities require plant registration under Victorian law)
• Training certifications for all staff working at heights

Emergency Response Planning

The agreement should address what happens if an incident occurs. For rope access and elevated work, this means:

• Emergency rescue procedures for suspended operatives
• Communication protocols with building management during incidents
• First aid capability on site during operations
• Incident notification obligations to WorkSafe Victoria

Building managers should be cautious of contractors who cannot provide detailed emergency response documentation on request. The absence of this documentation is a significant indicator of operational immaturity.

Co-liability Considerations for Building Managers

Victorian law imposes obligations on persons who manage or control a workplace to ensure, so far as is reasonably practicable, that the workplace is safe. For building managers, this means:

• Ensuring anchor points and rigging infrastructure are maintained in safe condition
• Providing contractors with relevant building safety information (anchor point load ratings, roof access protocols, exclusion zones)
• Not directing contractors to work in ways that compromise safety
• Ensuring any building-supplied equipment used by contractors is safe and maintained

The service agreement should document the information-sharing obligations on both sides, protecting the building manager from situations where a contractor argues they were not provided with relevant safety information.

Section 4: Cleaning Specifications and Performance Standards

Without defined performance standards, a service agreement is unenforceable — and this is one of the most consistent shortcomings in commercial window cleaning specifications for Melbourne building managers. A contractor who delivers streaked, spotted, or partially cleaned windows cannot be held in breach of contract if the agreement contains no acceptance criteria.

Streak-Free and Spot-Free Standards

The agreement should specify that completed window cleaning will be streak-free and spot-free when inspected from within the building and from external ground-level vantage points in natural daylight. This standard is achievable with professional equipment and technique, but it requires that:

• Water-fed pole systems use water with a total dissolved solids (TDS) reading of zero or near-zero, verified before commencement
• Traditional methods use appropriate squeegee technique with clean rubber and clean applicators
• Final inspection is conducted by the cleaning operative before departure

Hard Water and Mineral Deposit Specifications

Melbourne’s water supply contains dissolved calcium and magnesium carbonate that deposits on glass surfaces over time, creating mineral scaling that standard cleaning cannot remove. Buildings near irrigation systems, car wash facilities, or with sprinkler heads directing water onto glazing are particularly susceptible.

The agreement should address:

• How the contractor identifies mineral scaling during routine service visits
• Whether mineral deposit removal treatment is included in the standard scope or quoted separately
• The treatment methodology to be used — typically acidic descaling solutions applied by specialist technicians, followed by protective coating application
• Frequency of preventative descaling treatment appropriate for the property’s contamination profile

For Melbourne properties in hard water zones — much of metropolitan Melbourne has water hardness in the moderate to hard range — a proactive descaling schedule is more cost-effective than reactive treatment of severe scaling.

Tinted, Coated, and Specialist Glass

Many Melbourne commercial buildings incorporate performance glazing — solar control coatings, low-emissivity coatings, or tinted glass. These surfaces require specific cleaning approaches:

• Razor blade use is inappropriate on many coated glass surfaces and should be explicitly excluded unless the contractor can demonstrate knowledge of the specific glass specification
• Alkaline cleaning agents can damage certain coatings
• Abrasive materials — including some non-scratch pads — can cause micro-scratching visible in raking light

The service agreement should document the glass type for each building section and specify the approved cleaning methodology and chemical products for each surface type.

Frame and Surround Specifications

Where frame and surround cleaning is included in scope, the agreement should specify:

• Cleaning agents appropriate for the frame material (aluminium, powder-coated steel, timber, UPVC)
• Treatment approach for oxidised or weathered powder coating
• Sill and flashing cleaning standards

---

Section 5: Scheduling, Frequency, and Melbourne Weather Provisions

Melbourne’s weather is notoriously variable, creating genuine operational challenges for commercial window cleaning programmes. Effective commercial window cleaning specifications for Melbourne building managers must account for this reality — a service agreement that ignores Melbourne’s climate will produce a scheduling programme that consistently underdelivers.

Recommended Cleaning Frequencies by Property Type

Cleaning frequency should reflect the property’s location, glazing exposure, surrounding environment, and presentation standards. As a general framework:

CBD and inner-city commercial buildings — External cleaning quarterly minimum, with many premium properties requiring six-weekly or monthly programmes to maintain acceptable presentation standards. Melbourne’s CBD is affected by construction dust from ongoing development, vehicle exhaust particulates, and the particulate load from high pedestrian traffic.

Coastal properties — Salt air deposits from Port Phillip Bay accelerate contamination on properties in bayside suburbs from Port Melbourne through to Frankston. These properties typically require more frequent cleaning than equivalent inland buildings, with monthly external cleaning appropriate for properties within 500 metres of the bay.

Industrial and suburban commercial — Quarterly cleaning is typically appropriate for standard office and commercial buildings in Melbourne’s suburban ring. Properties adjacent to industrial areas, major roads, or construction sites may require more frequent attention.

Retail properties — Shopfront glazing in high-traffic retail environments accumulates contamination rapidly from pedestrian activity, food service proximity, and merchandise handling. Monthly cleaning is standard for active retail properties, with some food and beverage outlets requiring fortnightly service.

Aged care and healthcare facilities — Presentation standards in care environments reflect directly on resident wellbeing and family confidence. Six-weekly external cleaning is appropriate for most aged care properties.

Weather Contingency Clauses

The service agreement must include clear provisions for weather-related rescheduling. Melbourne’s weather creates legitimate operational constraints:

Wind restrictions — Rope access operations are suspended when wind speeds exceed safe working limits. The agreement should specify the wind speed threshold (typically 40-50 km/h for rope access, lower for EWP operations) and the rescheduling protocol when conditions are unsuitable.

Rain — Cleaning during rain produces poor results, as contamination from rain runoff rapidly re-soils cleaned surfaces. The agreement should define the protocol for postponing visits when rain is forecast or falling.

Temperature extremes — Cleaning in very high temperatures can cause rapid drying that leaves residue on glass, particularly in direct sunlight. The agreement should address hot weather protocols including early morning scheduling and shade management.

Rescheduling timelines — When a visit is postponed due to weather, the agreement should specify how quickly a rescheduled visit will be provided. A maximum of five business days from the original scheduled date is reasonable.

Seasonal Scheduling Considerations

Melbourne’s seasons create predictable windows of optimal and suboptimal cleaning conditions:

Spring — Pollen, construction activity, and variable weather make spring a challenging period for maintaining presentation standards. Pre-spring cleaning before October is valuable for preparing buildings for the warmer, drier months ahead.

Summer — January and February offer Melbourne’s most reliable dry weather, but extreme heat events require early morning scheduling. Pre-Christmas cleaning in November or early December positions properties well for the holiday period.

Autumn — April and May are generally Melbourne’s most settled weather months, making autumn ideal for comprehensive building cleaning campaigns. Leaf fall and associated organic deposits affect some buildings.

Winter — June through August brings Melbourne’s persistent overcast and wet conditions, making winter the most operationally challenging period. The agreement should address reduced visit frequency or alternative scheduling during winter months, with make-up visits in spring.

Annual Programme Documentation

For buildings receiving regular service, the agreement should include or reference an annual programme schedule that documents:

• Planned visit dates for each service frequency
• Internal versus external cleaning schedule
• Specialist treatments (descaling, facade inspection, seasonal deep clean)
• Contingency dates for each planned visit

This document gives building managers a forward planning tool and creates a record against which actual service delivery can be assessed.

Section 6: Associated Services and Building Maintenance Integration

Professional commercial window cleaning does not occur in isolation — it intersects with broader building maintenance programmes. Comprehensive commercial window cleaning specifications for Melbourne building managers should address these associated services and the opportunities they present for protecting the asset.

Facade Condition Inspection

Experienced rope access technicians working at height on a building facade have a unique vantage point for identifying building defects that are invisible from ground level. The service agreement should include a facade inspection reporting provision:

• Operatives should document any observed defects including sealant failure, cracking, efflorescence, corrosion, or glazing seal deterioration
• A written or photographic report should be provided to the building manager following each service visit
• Urgent defects presenting safety risk should be notified to building management immediately

This provision adds significant value to the cleaning service and positions the contractor as a building maintenance partner rather than a commodity supplier.

High-Pressure and Soft Washing

Many commercial window cleaning programmes can be efficiently combined with facade washing of cladding panels, concrete surfaces, and pavement areas. The service agreement should address whether high-pressure or soft washing of non-glazed surfaces is within scope, and if so, specify:

• Pressure limits appropriate for different surface types
• Chemical applications for biological growth removal
• Stormwater management obligations

Bird Proofing Inspection and Integration

Melbourne commercial buildings in CBD and inner-city locations frequently experience problems with pigeons and other pest birds nesting in and around window ledges, plant rooms, and structural elements. Bird activity creates significant contamination problems — guano is corrosive and creates persistent cleaning requirements.

The service agreement should acknowledge whether bird deterrent inspection and reporting is within scope, and how observations of bird activity will be communicated to building management.

Post-Construction Clean Coordination

When commercial buildings undergo fitout work, renovation, or facade repair, construction activities introduce contamination including silicone overspray, paint splatter, mortar, and construction dust. Post-construction cleaning requires different techniques and products to routine maintenance cleaning.

The agreement should specify:

• The process for requesting post-construction cleaning outside the standard programme
• Pricing or pricing methodology for post-construction work
• Response timeframe for urgent post-construction cleaning requests associated with building handover

---

Section 7: Communication, Reporting, and Accountability Mechanisms

A service agreement without accountability mechanisms is a statement of intent rather than a binding performance framework. Building managers should require specific reporting and communication provisions.

Pre-Visit Notification

The contractor should provide building management with advance notice before each service visit. Standard notice periods:

• Routine visits — 48 to 72 hours notice
• EWP and rope access operations — five business days minimum, to allow building management to notify tenants and arrange any necessary access

Pre-visit notification gives building management the opportunity to manage tenant expectations, arrange access to restricted areas, and raise any time-sensitive requirements.

Completion Reports

Following each service visit, the contractor should provide a written completion report documenting:

• Areas cleaned and access methodology used
• Any areas not cleaned with reason (access restriction, weather, building condition)
• Defects or issues observed during operations
• Equipment and safety documentation reference

Digital completion reports with photographic evidence are now standard practice among professional commercial contractors and should be expected.

Performance Review Process

For ongoing service agreements, the agreement should specify a periodic performance review process. A semi-annual or annual review meeting between the building manager and contractor account representative allows:

• Assessment of actual service delivery against the agreed programme
• Discussion of any presentation issues or recurring contamination problems
• Adjustment of cleaning frequencies or scope as the building’s needs evolve
• Review of compliance documentation currency

Rectification Process

Despite best efforts, occasional substandard work occurs. The agreement must define a clear rectification process:

• Timeframe for raising quality concerns following a service visit (typically within five business days)
• Response time for the contractor to acknowledge and address concerns
• Rectification visit timeframe (typically within five business days of acknowledgement for standard issues, within 48 hours for urgent presentation requirements)
• Escalation process if the initial rectification is unsatisfactory

Service Credits and Performance Penalties

Where a contractor consistently fails to meet agreed standards, the agreement should include a service credit or performance penalty mechanism. Common approaches:

• Credit of the relevant visit fee for visits not completed to agreed standard
• Reduction in annual programme value for consistent missed visits
• Termination rights for repeated performance failures

These provisions create genuine accountability and signal to contractors that performance standards are taken seriously.

---

Section 8: Insurance, Liability, and Indemnity Provisions

Commercial window cleaning on Melbourne buildings involves inherent risks — falling equipment, water ingress, glass damage, and personal injury. This is why commercial window cleaning specifications for Melbourne building managers must address insurance and liability comprehensively, rather than leaving these obligations ambiguous.

Required Insurance Coverage

The agreement should require the contractor to maintain and provide evidence of:

Public liability insurance — Minimum $20 million per occurrence for any commercial work involving access to heights or public areas. CBD and high-value commercial properties should consider requiring $20 million or higher. Building managers should request a certificate of currency annually rather than relying on documentation provided at contract commencement.

Workers compensation insurance — Current and valid workers compensation coverage for all employees. Sub-contracting arrangements must not be used to circumvent workers compensation obligations.

Plant and equipment insurance — Where the contractor uses owned EWPs, scaffolding, or other major plant, relevant equipment insurance should be in place.

Professional indemnity insurance — Where the contractor provides facade inspection or technical advisory services, professional indemnity insurance provides additional protection.

Glass Damage Liability

Glass damage is one of the most common disputes in commercial window cleaning. The agreement must specify:

• The contractor’s liability for glass damaged during cleaning operations
• The process for identifying and documenting pre-existing damage before work commences — a walk-through with photographic documentation before each campaign protects both parties
• Responsibility for reporting new damage identified during cleaning
• Limitation on contractor liability for damage caused by pre-existing conditions or defects in the glazing system

Water Ingress Liability

Water penetration during window cleaning, particularly on aged buildings with deteriorating seals, is a recurring source of building damage claims. The agreement should address:

• Contractor obligations to identify and notify building management of deteriorated seals before commencing cleaning
• Exclusion of contractor liability for water ingress through defective building elements that were identified and notified before work commenced
• Protocol for ceasing work and notifying management if unexpected water penetration occurs during operations

Indemnity Language

Standard commercial indemnity clauses should protect the building manager from liability arising from the contractor’s negligence. Legal review of indemnity provisions is advisable for large commercial contracts, as this area of contract law is nuanced and jurisdiction-specific.

---

Section 9: Contract Term, Pricing, and Variation Provisions

Contract Term and Renewal

Commercial window cleaning specifications for Melbourne building managers should address contract term and pricing transparency in equal measure — ensuring continuity for the contractor while preserving the building manager’s ability to address performance issues and market-test pricing periodically.

• Annual agreements with automatic renewal — providing continuity whilst allowing either party to review terms annually
• Two or three-year terms with CPI adjustment provisions — appropriate for larger properties where the contractor invests in equipment, staff training, and site familiarisation
• Month-to-month agreements — appropriate for smaller properties or where performance history with a new contractor is being established

Pricing Transparency and Inclusions

The agreed price should clearly document what is included and what will attract additional charges. Common additional charge scenarios:

• Additional visits outside the agreed programme
• Specialist treatments including descaling, graffiti removal, and post-construction cleaning
• Permit applications for footpath or road encroachment
• Additional travel time for mobilisation to distant suburbs within the Melbourne metropolitan area
• After-hours or weekend work required by building operations

CPI and Variation Provisions

Multi-year agreements should include a pricing adjustment mechanism to reflect labour cost inflation and equipment operating cost increases. A CPI-indexed annual adjustment prevents the need to renegotiate pricing annually whilst ensuring contractor viability.

Variation provisions should specify the process for scope changes — whether adding new building sections, changing cleaning frequencies, or including additional services. A formal variation process prevents scope creep without corresponding price adjustment.

---

Section 10: Termination Provisions

The agreement should provide clear termination rights for both parties.

Termination for Cause

Building managers should retain the right to terminate the agreement immediately in the event of:

• Serious safety incident resulting from contractor negligence
• Material misrepresentation of qualifications, certifications, or insurance
• Persistent failure to perform despite formal written notice and reasonable opportunity to rectify
• Contractor insolvency

Termination for Convenience

Standard commercial agreements include a termination for convenience clause allowing either party to exit with reasonable notice — typically 30 to 60 days. This provision protects building managers from being locked into underperforming contracts while giving contractors sufficient notice to manage resource allocation.

Transition Assistance

Where a building manager is transitioning from one contractor to another, the outgoing contractor should be obligated to:

• Complete any partially completed service visits
• Provide programme documentation and site access information to assist the incoming contractor
• Return any building keys, access cards, or other materials

---

Red Flags in Commercial Window Cleaning Agreements

Before signing any contract, building managers should benchmark the document against sound commercial window cleaning specifications for Melbourne building managers and be alert to the following warning signs:

No reference to WorkSafe compliance or safety documentation — any contractor unwilling to provide SWMS, certification documentation, and insurance evidence before commencement is presenting unacceptable liability risk.

Vague scope language — agreements that describe the scope as “clean windows” without specifics on surfaces, access methodology, or inclusions will inevitably produce disputes.

No weather contingency provisions — a contractor who does not acknowledge Melbourne’s weather variability has either not thought carefully about operations or is planning to deliver visits regardless of conditions and blame poor results on environmental factors.

No acceptance criteria — without defined performance standards, the building manager has no contractual basis for disputing substandard work.

Single document with no supporting programme — a professional commercial window cleaning contractor should be able to provide not just a contract but an annual service programme, site-specific safety documentation, and method statements tailored to the property.

Pressure to sign quickly — legitimate commercial contractors do not apply high-pressure sales tactics. The complexity of commercial window cleaning agreements justifies careful review, and any contractor unwilling to allow reasonable time for assessment should be treated with caution.
