Our exterior cleaning methods are safe for surfaces. Contrary to the common practice of many inexperienced pressure wash contractors, our goal is to clean your house using as little pressure as possible. This virtually eliminates concerns of water being forced behind siding, paint being blown off, and water being pushed in around windows and doors. Instead, we use biodegradable detergents to gently emulsify surface pollutants and kill mildew. That means our exterior cleaning service is not just safe to use around for surfaces, but also for the environment, pets and people.

Chemwash also follow strict Health and Safety Policies. These are supported by a comprehensive health and safety programme and manuals.


Chemwash is fully insured (5MM PL and $100k PI), and our staff undergo ongoing training in maintaining a safe and healthy workplace for customers. Our business offers a variety of up to date exterior cleaning options. Our objective is to provide quality and service at a reasonable cost. This objective is achieved by:
