House Washing Auckland

Exterior house washing

It’s important to keep the exterior surfaces of your home free of dirt, grime and mould to prevent them from rotting over time. Ideally, you should have a house wash every year to ensure protection from the weather, ensure your paint warranty is valid, and to kill any unsightly mould spores that can cause expensive structural damage if left unchecked.

Property pre-sale preparation

If you’re thinking of selling your home, remember that first impressions are key. Professional exterior cleaning adds value and can make a massive improvement to the presentation of your property. Unlike water blasting, low-pressure cleaning is suitable for cleaning any surface.

House washing prior to painting

If you are planning on painting your house, we recommend that you get in touch with us to arrange a low-pressure pre-paint clean and sterilization first. This will remove any dirt, grease or other contaminants to prevent future mould growth and to ensure that the paint adheres properly.

Soft wash cleaning technique

Unlike harsher water blasting techniques that can potentially damage exterior surfaces, we use a unique low-pressure exterior cleaning system and fan washing procedure. Our soft wash technique will kill any mould spores, whilst thoroughly cleaning the exterior surfaces to make them look like new again. Many of our customers are amazed at the difference to the aesthetic of their home after a Chemwash exterior house clean.

Biodegradable cleaning detergents

Our specially formulated cleaning detergents are tough on grime and dirt but gentle on surfaces. Its biodegradable formula means it won’t adversely affect plants in your garden and is safe for your whole family, including pets. We care about the environment as much as you do.
