CBRE Strata Window Cleaning Sydney

CBRE manages some of Sydney’s most prominent strata properties. Shimmer was approached by the CBRE management to maintain immaculate building exteriors across three towers, cause minimal disruption to residents and ground-floor retail tenants, and operate reliably within a schedule subject to weather-related adjustments.

The three-tower configuration added logistical complexity as each tower required individual access planning. Davitt arms built into residents’ balconies needed their own sequencing to keep that phase of work efficient and contained. CBRE needed a contractor who could manage that complexity without requiring ongoing direction from the building manager.

Site Assessment and Maintenance Planning for Strata Window Cleaning

Before work commenced, Shimmer conducted a full site walkthrough with the CBRE building manager. The team assessed glass condition across all three towers, façade exposure, access constraints, and the scheduling requirements of residents and retail tenants below.

From that assessment, Shimmer developed a site-wide maintenance plan covering cleaning frequency, method selection by area, and scheduling protocols. Shimmer scoped pressure cleaning for walkways and hard surfaces and planned window cleaning tower by tower. The team prioritised the Davitt arm sections for rapid completion to reduce the access window for residents.

Shimmer assigned a dedicated account manager to the engagement from day one. That manager handles schedule updates, weather-related adjustments, and post-service reporting directly with the building manager. Accordingly, the building manager receives detailed service reports after each visit, documenting areas completed, issues noted, and maintenance observations for future cycles.

Access Challenges Across Three High-Rise Towers

High-rise strata window cleaning in Sydney is directly affected by weather. Wind and rain can halt rope access and elevated work platform operations with little notice. To that end, Shimmer built its scheduling process to accommodate this reality. When conditions change, the account manager notifies the building manager promptly and adjusts the programme without requiring the client to follow up.

Jorge, Shimmer’s co-director, holds licences for boom lifts and scissor lifts and leads access planning on complex sites. With 27 years of experience, he resolves access problems across glass roofs, high-exposure façades, and buildings with non-standard window configurations. The Davitt arm sections at this CBRE complex required that same level of methodical planning. As a result, Shimmer sequenced that work to minimise the period during which balcony access affected residents and kept them informed throughout.

Safety and Certification for High-Rise Strata Work

Shimmer holds triple ISO certification that independent auditors review annually:

• ISO 9001 for quality management
• ISO 45001 for occupational health and safety
• ISO 14001 for environmental management

Shimmer also submits a current Safe Work Method Statement prior to commencing every job. The CBRE engagement has maintained a 100% safety record across three years of operation. For a high-rise strata site with over 1,000 residents, that record reflects both the quality of the planning process and the discipline of the on-site team. In practice, property managers who need to provide contractor compliance documentation to building owners or strata committees will find Shimmer’s certification and reporting structure covers that requirement directly.

SafeWork NSW publishes current requirements for high-risk work at height, which apply to all rope access and elevated work platform operations on sites like this.

Why Strata Window Cleaning at This Scale Requires a Planned Approach

A three-tower residential complex with active retail at ground level has no tolerance for uncoordinated cleaning activity. Residents need advance notice when balcony access is required. Retail tenants need assurance that work above them is properly managed. Building managers need a contractor who documents outcomes, not just invoices for them.

Shimmer’s engagement with CBRE reflects what strata window cleaning at this scale actually demands: a site-specific plan, consistent communication, a dedicated point of contact, and a certified safety framework. The relationship has operated on that basis since 2022 and continues.
