It’s very much a family business.

We have several employees who have been with the company for a decade or more, including second-generation Windowmakers and family duos on the team. This dynamic has shaped us into a truly family-oriented business.

Where it all started.

Windowmakers was founded in 2002 by Managing Director Heidi Johnston, based on a foundation of passion and expertise in architecture, engineering, and quality workmanship. The business was initially brought as First Windows and Doors North Harbour before being rebranded as Windowmakers, the name it is known by today.

One of the first priorities was the construction of a new factory and showroom, propelling the company forward and reshaping the industry. Fast forward to 2015, the demand for products and services had outgrown the capacity, leading to the establishment of a second factory in Silverdale. Playing a pivotal influence in the current development of our new facility, the merger of both Silverdale factories into one unified space aims to achieve ultimate business cohesiveness.

Heidi remains dedicated to Windowmakers, continuing her role as the Managing Director, working closely alongside Lance and serving as a key decision-maker on the Windowmakers Advisory Board.

What’s ahead.

As a dynamic and forward-thinking business, we continually seek opportunities to adapt and evolve. Our aim is not only to deliver aluminium joinery solutions that are current to the expectations of our clients and the demands of our industry but to ensure they are future-proof. We view every shift in the business landscape as an opportunity to innovate, improve, and elevate our standards to solidify our position as a leader in the aluminium joinery industry and a trusted partner for your bespoke windows and doors.
