Why Choose Dominator Christchurch
Dominator Christchurch, (formerly Summit Garage Doors,) is an owner‑operated family business primarily servicing the Christchurch Canterbury and North Canterbury region.
Founded by Dean Sangster, who learned the ins and outs of garage doors while living in Sydney, Australia, the business was born in March 2020 when Dean and his Kiwi wife returned to New Zealand to start a family and a new venture. Summit Garage Doors was a family business idea that has grown in strength with a strong focus on thorough communication, great workmanship, and customer care.
Dean brings years of hands‑on experience and a passion for solving garage door challenges of all sizes. Whether it’s a service, repair, new installation, or a custom solution, his goal is to take anything "Garage Door" related off your “to‑do” list and let you relax.
