Visiting the showroom in Dandenong and talking with Rudi and Sylvia gave us the confidence to go ahead with replacing 28 year old double glazed PVC windows/sliding doors in our living room in harsh beach side conditions. Technology and quality has improved remarkably over the years, backed with the high standard of German expertise, trusting that they will last the rest of our lives. Mario and staff installed the windows/doors efficiently, cleaning up after the job. Thank you for a reliable quality service. We are going ahead now with replacing more windows in our house.
