What we do and why choose us

Great service at a reasonable price

With Branches in Auckland, Tauranga and Dunedin we service Nationwide from Kerikeri to Invercargill, the Washco group of companies has a good reputation among facilities, asset, building and property managers nationwide for getting the job done right the first time.

All claddings, any surface

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

Delicate Cleaning: Caring for your property

Washco's experienced, industry-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 some of the delicate surfaces the Washco team can clean.


With Washco you can be confident that a senior member of the management team will turn up in-person to do an onsite inspection – that's how we get it right the first time. Big enough to have the resources, equipment and qualified people, Washco is also small enough to practise robust health and safety and to be more responsive and more reliable. It's why many Washco clients have been with the company for between 10 and 15 years.

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.

A big thank you to your and your team. Staff and residents found your team to be extremely helpful and courteous and an overwhelming vote that this is the best window cleaning the village has ever had. As a Village Manager I am very impressed with your compliance with H&S and reporting of any issues.

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.
