Helping you make a great first impression

With more than 20 years of exterior cleaning experience, Washco is well known for our respectful, friendly and expert service and quality finish. Some clients have worked with Washco for more than fifteen years – the longevity of the paint, cladding and joinery on their buildings is testament to our relationship.

Building Washing & Cleaning

All claddings, any surface

New Zealand’s diverse climate and geography places some unique demands on commercial buildings. Washco’s national wide experience across all claddings and surfaces – from aluminium and steel to concrete, composites and brick – ensure that your building will benefit from the correct expertise, optimal products and best technology for the job.

Window Cleaning

Brighter buildings, more sunshine

You can tell a lot about the people in a building by the condition of their windows. To help you make the best first impression upfront, Washco purifies the water from your taps before using it to clean your building and windows. This helps eliminate unsightly post wash spotting. Mop and blade – both art and technique – and soft brush cleaning (using state-of-the-art carbon-fibre water-fed telescopic poles) means Washco can reach windows up to five storeys without leaving the safety of the ground. For the rest, there is Washco’s abseiling team.

Roof Cleaning

Taking care of the frontline

Often the crowning glory of a building, the roof is often sadly neglected despite it being the frontline protecting the occupants from harsh weather and helping maintain a good internal climate.Washco offers two roof cleaning techniques:Pressure Washing: Depending on the type of roof, Washco’s working-at-heights team and specialist water blasters can help bring out the best in your roof.Moss and Mould Treatment: Washco uses iconic Wet and Forget products and supplies to clean and freshen all roofs of all types and sizes – particularly tiled and other delicate roofing materials.


Scaling new heights in cleanliness

This is the team to call when the project needs specialist industrial abseiling. Washco’s experienced at height access and industrial rope solutions cleaning teams can go where others cannot. Impeccable health and safety practises and superb at height techniques combine with professional cleaning skills for the best possible outcome.


Safe, fast and cost effective

Home to birds’ nests and leaves, gutters are an essential part of your property’s ecoystem and require a special approach – whether a one-off job or part of a full building wash.Washco uses a Skyvac Gutter Vacuum which allows gutters to be cleaned by a technician on the ground. A camera feature facilitates full visual control during the clean. Washco’s @Height team can take care of areas that are not easily accessible.

Delicate Cleaning

Caring for your property

Washco’s experienced, industry standards qualified technicians will assess the surfaces you need cleaned to determine the best techniques, tools and cleaning applications to get the job done. Heritage buildings, plaster clad facades and high-end stone cladding are just some of the delicate surfaces that the Washco team can clean.Ever respectful of your property, Washco will apply soft brush cleaning and low-pressure water blasting to finish the clean to avoid damage.Moss and mould treatments to delicate areas (without ever touching the building) can help preserve even the most delicate surfaces.

Carparks & Yards

A clean introduction

Carparks and Yards can quickly turn grubby with stains from exhaust fumes, oil, grease, gum and other types of dirt. They’re also one of the first things your customers and other stakeholders see. Washco’s mechanical scrubs – ideal for indoor concrete surfaces – and mechanical sweepers can lift and vacuum the dust and debris. Mechanical scrubbers and good quality cleaning applications do the rest. The finishing touches are added by a squeegee and vacuum.

We used “Wash Co” for the first time this year to clean the exterior of our villas and the community centre. We had all their health and safety documents prior to arrival and they signed in and out religiously every day. (very important these days!)The team were here for 4 ½ days. That was approx. 90 villas + a 1300m 2 comm centre.They were polite, thorough and did a fantastic job. Excellent communication with management throughout, and very cost effective.I highly recommend Wash Co.

On behalf of the team at Hugh Green Retirement Village, we would like to thank you for the brilliant job you did with the windows. Considering the enormous size of the job here, there was no disruption to residents, which is appreciated, and the residents are delighted to be able to see out the windows at last! I will be in touch soon to book the windows in for another clean in November.
