Locally owned and operated, Chemwash was the first New Zealand company to utilise soft washing cleaning methods. Soft washing is a low-pressure technique that uses specialised detergents to remove dirt, grime, and buildup. The low-pressure system is specialised for house washing and cleaning of all exterior surfaces. We provide comprehensive cleaning services for residential and commercial properties, including buildings, shopfronts, concrete washing, paths, gutter cleaning, roof treatments, fences, wooden decking, and outdoor structures.

Our environment is full of microscopic organisms that can cause unsightly buildup and growth on the exterior of your property. To prevent your outdoor surfaces from being compromised, it’s important to have them soft washed to remove these spores. This not only extends the life of your surfaces but also helps to protect your health by eliminating harmful bacteria.

Our Chemwash Cleaning System provides specialised sanitisation, which effectively cleans and disinfects all exterior surfaces, helping to eliminate algae, spores, and viruses. We can ensure zero face-to-face contact throughout the process to protect our community’s most vulnerable.
