Shimmer Glass and Pressure Cleaning has managed Hawkesbury Council window cleaning since 2017. Shimmer won the initial five-year tender and was reappointed for a second seven-year term in open competition. The contract covers a portfolio of low-rise and high-rise public buildings across the Hawkesbury region, including libraries, council chambers, administration offices, and community facilities.
Shimmer services nine Hawkesbury City Council sites under a single contract. Each site presents different access, height, and pedestrian traffic considerations, and the cleaning method is matched to what each building requires.
Sites serviced include:
At the Hawkesbury Leisure and Learning Centre, boom lift access is used for upper-level glazing. At Windsor Library, waterfed pole technology is used to clean large glass panels at height without disrupting public access. Scheduling is set around each building’s operational hours to maintain full public access throughout.
Government buildings present access challenges that standard residential or commercial cleaning does not. Hawkesbury’s portfolio includes high-traffic public entry points, elevated glazing, large glass roofing, and structures that require careful handling.
Jorge, Shimmer’s co-director, holds licensed operator certification for boom lifts and scissor lifts. He leads all high-access and technically complex jobs on site. With 27 years of hands-on experience, he identifies the most efficient access method for each building and adapts the approach when site conditions change.
In practice, Shimmer does not bring a fixed method to a site. The approach is assessed per building and adjusted over time as the contract matures.
Shimmer holds triple ISO certification: ISO 9001 for quality management, ISO 45001 for occupational health and safety, and ISO 14001 for environmental management. These are independently audited and maintained annually.
Every job is completed under a current Safe Work Method Statement submitted prior to commencement. All team members hold current police checks. The Hawkesbury Council window cleaning contract has maintained a 100% safety record since 2017.
For current NSW government contractor safety requirements, refer to SafeWork NSW.

Shimmer assigns a dedicated account manager to the Hawkesbury contract. That person maintains direct communication with each building manager, provides schedule updates, and documents any issues identified during service.
After each visit, a written report is submitted covering areas cleaned, any access or condition issues noted, and maintenance recommendations for future service cycles.
The Hawkesbury City Council contract is one of a number of government and council cleaning partnerships Shimmer manages across the greater Sydney region. If you manage public facilities and are preparing for a tender or contract renewal, Shimmer’s government window cleaning services cover the full range of access methods, compliance documentation, and reporting required by local government procurement teams.
