What we clean

We wash exterior walls, eaves, joinery, and spouting on classrooms, school halls, administration blocks, and early childhood buildings. We also clear gutters, apply roof treatments, wash decks, paths, and car parks, and treat shade sails and shade structures for mould and lichen.

Our telescopic reach extends to 15 metres, which means most shade structures and multi-storey buildings can be cleaned without scaffolding or elevated work platforms. This keeps the job faster, less disruptive, and more cost-effective.

We also wash adventure playgrounds and outdoor play equipment. We take care around planted areas, gardens, and any surfaces tamariki come into direct contact with, and we use biodegradable solutions throughout.

How we plan the work around your school or centre

Most of our school and early childhood work is scheduled during school holidays, teacher-only days, and weekends. When jobs do need to happen during term time, we plan around bell times, break times, and the areas tamariki are using.

We do not simply turn up and start. Before the job, we identify access points, confirm which areas need to stay clear, and make sure cleaning solution runoff is directed away from play spaces and gardens. We brief our team on site-specific requirements every time.

For centres with strict no-children-on-site requirements during cleaning, we confirm the timing and access plan in writing before we begin. We have worked with early childhood networks across Northland and understand the compliance requirements that come with the territory.

Real example
We look after a network of early childhood centres across Northland. Across 26 locations including a head office, we run a six-monthly maintenance programme that covers roof treatment, gutter clearing, building wash, shade sail treatment, concrete and path cleaning, and play equipment washing.
The network operator books once and we take care of the rest. Sites are scheduled across the relevant school holiday period so there is no disruption to children, families, or staff. Every site gets the same scope of work.
After every single centre, we produce an image-rich post-wash report. This includes before and after photos of the building exterior, roof, gutters, and any hard surfaces we have cleaned, plus photos of any problem areas spotted during the job. Every report goes to the property manager digitally, usually the same day.
For a multi-site operator, having one accredited contractor who understands the scheduling requirements, knows the sites, documents the work properly, and does not need to be chased is the whole point.

Roof treatment vs roof washing for school buildings

‍

We are sometimes asked to quote for a roof wash on school buildings where what is actually needed is a roof treatment. The two are not the same, and the difference matters.

Our team arrives prepared. Every job is set up properly before we start, with equipment, hoses, and access plans confirmed on site.

Roof treatment applies a slow-release solution that kills lichen, moss, and black mould at the root and keeps the surface clear for significantly longer than washing alone. Washing removes the visible growth but does not treat the spores underneath. Growth returns faster after a wash. On a budget cycle, treatment is almost always the better investment.

Real example
A large Whangarei high school had been paying for roof washing on a regular cycle through a facilities management company. When they came to us for a quote, we assessed the roof and recommended switching to a treatment programme instead.
The roof had not been treated, only washed. Growth was returning within months each time. We switched them to an annual treatment programme. The roof stayed clear for the full year between treatments, and the school saved a significant amount compared to what they had been spending on repeated washes.
We will always tell you which approach is right for your building and why. If a wash is the correct call, we will say so. If it is not, we will say that too.

For centres and schools with specific chemical use requirements or sensitivities, let us know at quoting stage and we will confirm exactly what we use and how we manage it on site.

When we apply solutions near planted areas, sand pits, vegetable gardens, or water features, we redirect runoff and cover the areas where needed. We take this seriously. It is not an afterthought.

Post wash report

We use biodegradable cleaning solutions across all our school and early childhood work. These are safe once dry. We do not use harsh chemicals, bleach-heavy solutions, or products that leave harmful residue on surfaces tamariki touch.

On request, we provide a post wash report after cleaning your school or early childhood buildings. The report includes photos of any areas showing signs of damage, wear, rot, or erosion that we spotted during the job.

Chemical safety and care around play areas

School buildings often have areas that are difficult to see from the ground, particularly around roof edges, soffits, gutters, and upper-level joinery. Our technicians are up there with the right gear, so they see things a routine ground-level inspection misses.

We cover all of Whangarei and Northland, and we work with single sites and multi-site networks. Get a quote and we will come back to you within 1 to 2 hours during business hours.

Catching a damaged soffit or early-stage rot before it becomes a serious repair is exactly what a post wash report is for. For boards of trustees and property managers making maintenance decisions, having documented photographic evidence of problem areas can make the difference between a small repair and a large one.

Frequently asked questions

When do you schedule school cleaning jobs?

We schedule the majority of school and early childhood centre work during school holidays, teacher-only days, and weekends. We can work during term time when needed, and we plan around bell times, break times, and the areas tamariki are using. We confirm timing and access in writing before the job begins.

Are your cleaning solutions safe around children?

Yes. We use biodegradable solutions throughout all school and early childhood work. These are safe once dry. We take particular care around play equipment, sand pits, planted areas, and water features, and we manage runoff to keep these areas clear during the job.

Can you work on multi-site school networks?

Yes. We work with multi-site operators across Northland, including early childhood networks with 20 or more locations. We coordinate scheduling across sites, maintain consistency of scope, and report back on any problem areas spotted during each job. You book once and we take care of the rest.

What is a post wash report and do you provide one?

A post wash report is a written and photographic record of any damage, wear, rot, or problem areas we spotted during the cleaning job. We provide these on request. They are particularly useful for school buildings with hard-to-see areas around soffits, roof edges, and upper-level joinery. Ask about this when you request your quote.

Do you provide a health and safety compliance record for our files?

Yes. We hold SiteWise Gold accreditation with a 100% score across two consecutive years, and nine consecutive years of accreditation in total. We can provide our SiteWise certificate on request. Our technicians hold WorkSafe-recognised working at heights qualifications, and we carry out site-specific hazard identification and WorkSafe notifications where required.

What is the difference between roof treatment and roof washing for school buildings?

Roof treatment applies a slow-release solution that kills moss, lichen, and black mould at the root and prevents fast regrowth. Roof washing removes visible growth but does not treat the spores underneath, so growth returns sooner. For most school buildings on a maintenance budget, treatment is the better investment. We assess each roof and recommend the right approach for your building.
