An investment in quality for your strata building

Apartment window and door replacement is a specialist job, where high-quality products, professional service and efficient processes are key. As industry leaders since 1989, Windowline is the trusted choice for strata window and door installation in New South Wales and Queensland.

Strata building work can be complex, messy and disruptive for your residents. With over 30 years in the business, we’re experts at minimising disruption and getting your job done quickly and smoothly from start to finish.

Unlike many other companies, Windowline is not aligned with a single window or door manufacturer, but work with all leading suppliers. This enables us to make recommendations based on your specific needs – rather than choosing from a limited product range – to deliver the best solution possible.

Our highly qualified team has built up a reputation for providing personal, professional and efficient service every time, resulting in repeat business and positive testimonials from many satisfied clients. Much of our new business is due to referrals by our satisfied strata manager clients – both past and present.
