A family of established industry leaders in building wash, window clean and engineering work-at-height.
About Us
One group.
Five specialist companies.
Any height, every capability you need.
The formation of Hawk Services Group was driven by a common vision: to provide our customers with exceptional services and a seamless experience.
Together, we are New Zealand’s leading names in exterior cleaning, rope access, and height safety. Our five specialist brands are proven in their fields, with reputations built on consistent results, strict safety standards, and nationwide reach.
When you work with one of us, you benefit from the combined expertise of the group — backed by specialist equipment, certified technicians, and decades of experience.
Nationwide presence, local dedication
With a nationwide presence, we have established ourselves as the largest and most reliable provider of commercial building washing and window cleaning services in the country.
Collectively, we cater to a diverse clientele in various industries. Whether it's in the city center or more remote, we deliver top-notch services, tailored to meet the unique requirements of each location.
Our team of experts is equipped to handle projects of any scale, be it commercial complexes, industrial facilities, or residential towers.
Safety is our foundation
Hawk Services Group is synonymous with safety. When it comes to any work at height, we adhere to the strictest safety protocols and regulations, ensuring the well-being of our team members and clients alike. Our skilled engineers are trained to handle any project, no matter how complex or challenging, with utmost professionalism and safety as the top priority.
Through PREQUAL contractor prequalification, our health and safety policies, practices, and procedures have been independently assessed and verified. This gives clients confidence that we not only meet but actively maintain industry expectations.
We align our practices with WorkSafe NZ guidelines and legislative requirements, and we work with clients to comply with their health and safety processes.
Our insurance cover includes $20 million public liability, and we are committed to keeping this current. Above all, we are committed to doing the right thing — operating safely, transparently, and responsibly on every site.
Investing in our people
Our strength comes from our teams. Each year, we put in over 2,000 hours of training to keep skills sharp and knowledge current. This commitment means our people stay at the top of their game — giving clients confidence that every project is delivered to the highest standards of safety and quality.
Service reports
We keep clients informed with detailed service reports after every job — complete with photos and notes on any areas needing attention. Since assets like roofs and gutters are often out of sight, this visibility helps clients stay proactive, catching issues early before they turn into costly problems.
Experience unmatched service
Customer satisfaction is at the core of everything we do. Our skilled technicians, advanced equipment, and customer-centric approach ensure a seamless experience from start to finish. We take pride in building lasting relationships with our clients, earning their trust through consistently exceptional results.
Never content to stand still, we are continually innovating. This includes our introduction of drone technology to complement our existing services.
Just as we select between rope access, wash trucks, or ground crews depending on the site, drones give us another option, to ensure we deliver the best overall solution.
Drones are especially valuable for inspections, façade cleaning, and chemical application on large or complex rooftops. They reduce access costs, minimise risks by keeping people off inaccessible rooftops, and provide detailed proof of coverage — ensuring every job is completed faster, safer, and with greater accuracy.
