We were the first exterior cleaning company in New Zealand to utilise a low pressure cleaning system, in combination with environmentally friendly detergents that are gentle on surfaces, but hard on dirt. Regular house washing and cleaning is more than keeping your house looking pristine. Having a professional wash your house is essential to prevent permanent damage to your home such as staining, mould growth and more.
