Fascias are architectural components, so before any house washing takes place, we will inspect them to ensure no urgent repairs are required


Eaves are the part of the roof that hangs out over the walls to provide shade and weather protection to the windows and outside of your house.

Roof Junctions

We will check all lower roof to wall connections before conducting the house wash and any other roof job for a thorough roof treatment.


Ensure your cladding is free from moss, mould, or any further contaminants that could cause your cladding and or coatings to prematurely fail or break down. We also ensure the cladding does not have cracks or defects and catch small repairs before they become costly or extensive.


We make sure that your joinery/glazing seals and joinery-cladding junctions and sealant are performing as required to ensure weathertight junction before house washing commences.

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

We properly inspect your property before beginning to make sure that our house wash service leaves your North Shore property spotless, properly repaired and inspected for weather tightness to maintain your property’s good condition for years to come. Customer satisfaction and a great job done are our priorities.


Our house wash services include the process of clearing away foreign objects, dirt and grime during the exterior cleaning process. We remove cobwebs and clean the outside of guttering, barge board, flashings, all exterior cladding, gables, window exteriors, exterior paint and framework.

Keeping on top of your exterior cleaning prolongs your property’s lifespan. Through regular house wash and maintenance services, we can detect damage early to be able to fix it, maintain and uphold your exterior paint warranties, as well as keeping the property looking great.

Absolutely. Our house wash services on the North Shore uses eco-friendly house washing products and processes. This natural house wash still performs and delivers quality results. It cuts through dirt, grease and stubborn grime just the same, if not better, than chemical house wash cleaners.

We are incredibly conscious of unnecessary water wastage on the North Shore, especially during the summer 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 house washing services trailer, and it’s used in our house washing services.

Not at all. Our exterior cleaning processes and products are gentle enough that they will not hurt 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 washing products.

Eventually, yes, but we make sure it is safe to do so by the time that it does. Before we begin washing an Albany house, we inspect the property and what needs to be cleaned first. If there is light to medium organic dirt and debris on the home, it is safe to be washed straight into the North Shore 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 North Shore stormwater system.

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

We provide these services to adhere to those warranties! Our house 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 homes. Weather tightness just means that all points of your home are safe from the external elements, and the inside of your home is dry and stays dry.

If there is weakness in your exterior cladding or other points of construction, then your home is at risk of weather damage and possibly leaky home syndrome.
