Commercial · New Zealand
Kiwi Maintenance Group has been delivering commercial building washing to office towers, rest homes, schools, and industrial facilities across New Zealand since 2010. We have 50+ directly employed staff, in-house access capability, and ISO 45001:2018 certification. Our company provides Facility Managers a building wash contractor they can schedule, trust, and forget about.
Not every exterior cleaning company understands the difference between a high-value commercial building in an active environment and an empty car park. The wrong approach, wrong chemical, or wrong pressure on a premium facade can cause damage that costs far more to fix than the wash itself.
KMG crews are trained to assess surfaces before any work begins, select the correct method and chemical mix for each substrate, and deliver a result that protects your asset as well as cleaning it. We have been doing this work since 2010 and the investment in training and equipment shows in every job.
For Facility Managers, the biggest risk with exterior cleaning is not the cleaning itself. It is the disruption. KMG crews are specifically trained to work in active environments, including occupied office buildings, operational rest homes, and busy school campuses. We coordinate timing around your schedule, pre-water gardens before chemical application, cover electrical fittings and sensitive surfaces, manage noise levels, and leave every access point exactly as we found it. Your tenants and staff should barely notice we were there. That is the standard we hold ourselves to on every job.
Every KMG staff member who arrives at your building is directly employed by us, not sourced through a subcontractor or labour hire agency. We operate with 50+ staff nationwide, all trained to our internal standards and managed through our job management system. For Facility Managers, this means the same people return visit after visit, retaining your site knowledge and protocols without you having to re-brief anyone. Our compliance documentation, SWMS, toolbox meetings, and incident reporting are all managed in real time through our cloud-based HSE app, so you have full visibility whenever you need it.
KMG holds ISO 45001:2018 certification for occupational health and safety, a standard that many exterior cleaning companies in New Zealand cannot demonstrate. We are Site Wise Gold certified, the highest certification level available through Site Safe, and pre-qualified through both Impac Prequal and CM3. For Facility Managers who manage contractor approval processes, KMG arrives already vetted. No chasing documents. No compliance gaps.

Most commercial buildings benefit from a wash once or twice a year, depending on location, facade material, and surrounding environment. Buildings near the coast, busy roads, or industrial areas typically require more frequent washing. KMG can assess your building and recommend a maintenance schedule that protects your asset year-round.
KMG uses a combination of soft washing with biodegradable chemical treatments and low to medium pressure water blasting, depending on the surface substrate and level of soiling. Our crews assess each facade before work begins to ensure the correct method is applied. We never use indiscriminate high pressure on surfaces that could be damaged.
KMG is trained to work in active, occupied environments. We schedule around your operational requirements, manage noise, pre-protect gardens and fittings, and coordinate access with minimal disruption. Most clients report that their staff had no awareness the work was taking place.
