Frank by Ostaco is a family-owned Canadian maker of custom vinyl windows and doors. Its made-to-order approach gives you a choice of sizes, styles and finishes for a renovation or new opening. If you want a traditional window look in vinyl, this line may be worth comparing.

Ostaco develops its products with feedback from dealers across Canada. Ridley will help you compare styles, glass and hardware in plain language, including where a simpler choice will do the job.

Vinyl is only one part of the decision. Accurate measurements, the condition of the opening and careful installation all affect the final fit. We measure on site before preparing a quote, finish the trim and clean up when the work is done. Our warranties and aftercare continue afterward.
