Clean Haven's ute and traffic control set up outside an apartment building

Project overview

CleanHaven was engaged to clean the exterior of a multi-building property in NSW. The scope covered the building surfaces, common-area pressure cleaning, concrete cleaning and a general lift in presentation across the site.

The work was staged to keep disruption to residents, tenants and operations low, while dealing with heavy build-up in high-traffic, high-visibility areas.

The challenge

Built-up dirt, mould, algae, and surface staining across multiple buildings
High-traffic areas requiring careful access management
Need to minimise disruption to residents, tenants, and operations
Multiple surface types and access points requiring different methods
Property presentation a priority for management

The scope

Building exterior wash-down across multiple levels
Common area pathways and courtyards
Car park and basement garage cleaning
Concrete surfaces and hardstand areas
Entry areas and foyers
Bin room and bin pad cleaning
Spot treatment for oil, grease and algae stains
Final inspection and before/after photo documentation

The result

Cleaner, safer-looking common areas across the site
Improved street appeal and overall property presentation
Better experience for residents, tenants, visitors, and management
Full before/after photo documentation provided to client
Ongoing maintenance plan established for continued presentation
