About Nicco

Bellevue Hills Timber Windows

Founded in 1998 by industry veteran Nicholas Toskas, NICCO Timber Windows & Doors (previously Nicco Joinery) began as a boutique manufacturer.

Prior to founding NICCO, Nicholas' experience in the joinery industry began in the late 1960s. Initially working with his family running a local hardware store in Sydney’s Marrickville, he then went on to co-owning the legendary Tosca Joinery.

Today, NICCO is a second-generation family business run by Nicholas’ eldest son John Toskas. John’s passion for the industry and family business was instilled at a young age. In fact, John has been with his father from the inception of NICCO and is proud to champion his father’s legacy as well as his vision to be the most trusted name in custom-made timber windows and doors.

Working closely with architects, builders and designers across both commercial and residential projects, John and the 30+ team at NICCO is committed to bringing together traditional joinery expertise with industry innovation to produce timber windows and doors of exceptional quality.

We proudly train our team to offer innovative and expert thinking to ensure NICCO remains at the forefront of the industry, while remaining socially responsible and continuing to pay homage and respecting the traditions that have made us who we are today. This uniquely positions us to deliver industry leading solutions to meet our client's needs with integrity and authenticity.

Australian made to rigorous Australian standards, NICCO combines traditional joinery methodology (such as wedged and glued mortise, and tenon junctions) with state-of-the-art manufacturing techniques (e.g. computer-operated CNC machinery) to produce custom made timber windows and doors to suit any project.

We are competitively priced, and our lead-times are amongst the best in the industry. We partner with our clients at every stage of the process from design, quotation, order-placement, preparation of NICCO workshop approval drawings, manufacture, delivery and after-sales service.
