About Us

Chemwash Exterior House Cleaning

Chemwash Waikato

At Chemwash Waikato, we are always striving to be the best at what we do. We are vastly experienced, versatile and local. The advantage of calling your Chemwash operators is that we can tackle any sized job, residential or commercial, with a state of the art health and safety system that is updated annually.

Our licensed areas cover Hamilton & Cambridge, stretching out to the wider Waikato region. Part of a national franchise, Chemwash Waikato is one of many Chemwash operators nationwide.


Chemwash was formed in 1981, bringing a new cleaning technique to the exterior cleaning market. Using non-poisonous and non-toxic detergents to do all of the ‘hard work’, the Chemwash system replaces high pressure water blasting, changing the game completely. Water blasting is still used extensively today by many other cleaning companies, which is a lot more dangerous. With Chemwash however, there is no risk of damaging surfaces.

Developed by a leading industrial chemist, our detergents are totally safe to use around buildings and houses, effective in the selective killing of mould, lichen and moss, while simultaneously cleaning away dirt and grime. Of course, our detergents were also made to be totally safe around people, pets and all general vegetation.
