what our clients say..
“Millbrook have had a long association with S J Allen who have been vital to our waste management. They collect our rubbish, manage our recycling, clean, and dispose of waste from sumps, drains, grease traps as well as clearing those blockages that would bring us to our knees. The growth in Millbrook is reflected in the capability and scale of S J Allen’s operation, where they can provide both reliable services on a weekly and seasonal basis as well as the urgent calls for help. Their staff understand our business and work to minimise disruptions, often working out of hours to avoid problems.”
Mike StaceyMillbrook, Facilities & Property Manager
“I have really enjoyed working with the SJ Allen team over the past couple of decades. They understand events, plan their operations well and deliver on time. They are one supplier you don’t need to worry about, no matter where or what the delivery requirements are, they work hard to find the solutions and get the job done. I would wholly recommend using this supplier for your events or venue.”
Nicole FairweatherFormer race director/manager of Queenstown Marathon
“SJ Allen have provided a dependable cartage service to QLDC since 2017. The service they provide ensures the district’s wastewater sludge can be safely disposed of, and as a result its wastewater treatment plants can operate effectively. The SJ Allen team has been reliable over the term of the contract and always willing to go the extra mile to get the job done”
