Chemwash Waikato

New Zealand's leading house wash
and exterior cleaning company.

Why Chemwash?

Chemwash has been soft washing houses in Hamilton, Cambridge and the wider Waikato region for over 30 years. We specialise in both residential house washing and commercial building cleaning. We can also clean concrete, roofs & gutters, fences, decking, windows, outdoor furniture and more.

Founded in 1981 and 100% kiwi owned, Chemwash is a leading pioneer in the exterior cleaning industry. We were the first house wash company in New Zealand to use the combination of low water pressure and biodegradable detergents. The Chemwash cleaning system is extremely versatile and safe, specialised for all exterior surfaces. That means we can produce great results, with no risk of damage to your property.
