Our partners


We are South Australia’s largest fabricator of uPVC Windows and Doors.

Founded in 2004 by Paul McCabe, a Scotsman passionate about high quality windows and doors, the company has grown steadily over the years. In 2017 we took a great leap forward by doubling the size of our Lonsdale factory, building a showroom and welcoming our Sales Manager Leila to the team. Leila worked for a German uPVC extruder for over 16 years in Scotland bringing a wealth of experience and enthusiasm to the party.

Paul, Leila and our highly skilled and experienced fabrication and installation teams take our projects and customer experiences very seriously. From quoting and planning right to the end of the job, we are with you every step of the way to ensure your complete satisfaction and we will be here for any questions you have for the years following the completion of your project.
