Before any work begins, the site is set up properly.

Signage in place, access controlled, and the people around us informed. It is a standard we hold on every job, at every site, nationwide.

15/06/2026

Gutters do not fail all at once.

Debris accumulates gradually. Leaf fall, sediment, moss build-up, until drainage is compromised and water finds another path. A blocked gutter in winter is a water ingress risk. Clearing them before conditions worsen costs a fraction of what it costs to fix.

The world's first 100% electric robotic building wash machine.

Developed by SummitBWT, operated by JT Group. It works from the ground, reduces water use by up to 85%, and produces zero on-site emissions.

Already operating at Auckland Airport, Wellington Airport, and Hnry Stadium.

Every long-term client relationship we have started the same way. Someone needed a job done properly, without disruption, and without having to follow up.

That is still the brief, sixty years in.

07/06/2026

Planned Preventative Maintenance isn't complicated.

It's a scheduled cycle of roof washing, gutter clearing, facade treatment, and chemical application. Agreed in advance, carried out on time. For facilities managers, it means fewer reactive callouts and no winter surprises.

Some jobs require getting closer to the work.

Our abseiling teams carry out high-rise building washing and maintenance where ground-based access is not an option. Safely, methodically, and with minimal disruption to the people using the building.

More than 60 years of working at height. The standard does not change.

02/06/2026

High-risk work requires the same standard regardless of conditions.

As a business, we hold SiteWise Gold and Totika certification - not because we have to, but because it reflects the standard we work to. On every site, regardless of weather, access complexity, or building type.

28/05/2026

Abseiling requires training, planning, and a team that works at height every day.

Our crews are experienced rope access operators - and where the building or environment calls for it, we also operate ground-based robotic wash technology developed by Summit Building Wash
Technologies.

Every access method, covered.

Petrol-powered building wash equipment is the industry norm. It doesn't have to be.

JT Group operates world leading battery electric systems developed by Summit Building Wash Technologies - eliminating on-site carbon emissions and saving up to 96kgCo2 per day versus petrol alternatives. Each electric machine removes the equivalent of 8 vehicles from the road.

500+ tonnes eliminated annually across our nationwide fleet.
