Commercial Window Cleaning
CrestClean’s Pure Water Window Cleaning provides cost-effective high-rise window cleaning for buildings up to 4 storeys high.

Our specialised professional window cleaning system converts tap water into ‘pure water’ by passing it through filters and resins which remove any minerals that can leave deposits or stains on windows.
Along with delivering great results, our Pure Water Window Cleaning service uses no chemicals, meeting strict environmental standards as verified by our Toitū Enviromark Diamond certification. Health and safety is simplified because ladders and platforms are not required to access higher windows, and the price is less because the extra equipment is not needed.

No chemicals are used with Pure Water Window Cleaning. The mineral deposits in tap water are filtered, allowing the water to clean better at an ionic level. The results are clearly cleaner windows without spots or streaks, without harming the environment.
With the latest carbon fibre extendable poles we can clean high windows without using platform lifts or ladders. No power is required – only a hose tap.
Risks and hazards are dramatically reduced when compared with conventional high-rise window cleaning services. Our operators work from the ground only. We also prepare site-specific safety plans including pedestrian and traffic management.



We bring more than just a squeaky clean attitude to our window and glass cleaning services – we bring innovation.
Our Pure Water Window Cleaning services use high-tech water filtration to remove all solids, leaving only pure water to clean your windows… without spotting or streaking. With a carbon fibre pole, one operator can quickly and efficiently clean high windows, window frames and glass, all while meeting strict Health and Safety standards. CrestClean’s Pure Water Window Cleaning provides cost-effective, chemical-free window cleaning solutions for buildings up to 4 storeys high.
CrestClean’s Pure Water Window Cleaning uses no chemicals, making it both cost-effective and environmentally responsible. The purer the water, the more effective it becomes, acting as a natural detergent that loosens dirt from glass at an ionic level. Free of impurities, this pure water eliminates the need for detergents or chemicals and rinses cleaner, leaving windows streak-free and spot-free.
Using the latest extendable carbon fibre poles, we can clean windows up to 4 storeys high without ladders or lifting platforms, making Pure Water Window Cleaning a safer alternative to other commercial window cleaning options. There is no risk of property damage from ladders and heavy equipment, and our specialised water purification machines do not require power, only a hose tap.
Compared with conventional building and office window cleaning, risks and hazards are dramatically reduced because our operators work from the ground using carbon fibre poles. We don’t work from heights or use ladders or platforms. All activities are conducted under SafeClean®, our Health, Safety and Environmental Management Systems, which are specifically designed to minimise the risk of our work on your premises.
All CrestClean Pure Water Window Cleaning technicians receive specialised training in the safe operation of the system. This is in addition to the professional industry training they undergo, including specific health and safety training in safe working procedures. See mastercleaners.org.nz
