Looking For A Building Washing Company in Auckland?

Born from one of the leading leaky home repair companies in Auckland, we are your specialist building washing company that goes beyond just a wash and leave!

We make sure your property benefits from a thorough, expert building washing service that doesn’t cut corners or leave damage behind!

We properly inspect your property before beginning to make sure that our building washing service leaves your Auckland property spotless, properly repaired and inspected for weather tightness to maintain its good condition for years to come.


Building washing is the process of cleaning any foreign dirt and matter from the exterior of a property.

Keeping your house exterior clean and free from debris prolongs its lifespan, allows any damage to be better detected early, upholds your exterior paint warranties and keeps the property looking its best.

Yes! Our building washing services in Auckland use environmentally conscious building washing products like our building wash.

This natural building wash formula cuts through stubborn grime, dirt and grease just as well, if not better than, chemical cleaners.

Our building washing product is carefully formulated to quickly penetrate, emulsify and remove light to medium dirt debris. Being made from natural plants and minerals, the building wash leaves behind no chemical fumes or residue! It’s our proudly 100% natural building washing solution!

We are very conscious of water wastage in Auckland, particularly during drier seasons where water restrictions are in place.

Wherever possible, we use clean recycled water from hospitality premises like motels, hotels and environmentally-conscious hotels. We reuse the final rinse water that was used in cleaning linen in commercial buildings with eco-friendly products in a partnership that allows both of our industries to be less wasteful.

The water from this final rinse process is diverted and stored, we pick it up in our purpose-made 2000lt wash service trailer and it’s used in our building washing service.

Nope! Our building washing products are gentle enough that they will not harm any outdoor furniture if any of the water or product sprays should land on them, and the soil and plants can even benefit from the extra nutrients in our eco-friendly house washing products!

Eventually, yes, but we make sure it is safe to do so! Before we begin washing an Auckland building, we inspect the property and what needs to be cleaned first.

If there is light to medium organic dirt and debris on the property, it is safe to be washed straight into the storm system. If the debris is particularly heavy, contains paint flakes and other non-eco-friendly matter, we will block the storm drains off first before beginning so that we can filter the non-eco matter out of the dirty water before allowing it to run into the stormwater system.

No, in fact, if you read your terms and conditions of your paint warranties – particularly from companies like Resene, Wattyl and Dulux, you will find that they require a recorded annual building washing in order to maintain the valid manufacturer’s warranty.

We provide these services to adhere to those warranties! Our Auckland building washing process and products are approved by all the markets leading paint manufacturers to keep your warranty valid.

Our experts come from lengthy experience dealing with weather tightness in Auckland properties. Weather tightness just means that all points of your building are safe from the external elements and the inside of your property is dry – and stays dry. Before we begin an Auckland building washing service, we need to check that us spraying water and products onto your building is not going to seep through any cracks in the weather tightness.

If there is weakness in your exterior cladding or other points of construction, then your property is at risk of weather damage, and water damage from being washed.
