Customize Ostaco Window and Door Shapes and Shades to Suit Your Needs

Ostaco’s stellar reputation is based both on their quality and ability to create virtually any shape, size and colour of windows and doors that you want. So let your creativity have free reign! Octagon, trapezoid, hexagon, gothic, segmental, oval or double-cornered windows—the only limit is your imagination.

Matching a paint colour or custom shade is just as easy. Simply bring 2 colour samples and we will begin the colour matching process. Once you have approved the sample we send back to you, Ostaco will paint your custom designed windows or doors in the shade you choose.

How to Design Your Ostaco Moose, Bi-Folding and Sliding Patio Doors

Hinged Entry Doors

  • Choose the perfect colour: With 24 paint colours as well as custom colour match options, you can have virtually any shade that you want.
  • Select the finish: Whether you decide on a grainy or smooth finish, it’s all up to you. Rustic mahogany, American fir, oak, cherry, knotty alder—there are so many choices.
  • Available options in Stain-grade Fiberglass
  • Determine panel style: Available in a range of heights and widths, door panels can be designed to match your architectural style. Choose from flush, 3-panel craftsman, camber top, plank, and more. You can also enhance the look of your door with a finely-crafted dentil shelf. Ideally-suited to craftsman doors, it adds character and creates a striking focal point.
  • Select the right glass: A choice of glass shapes such as craftsman, oval, scroll, square, camber/arch, etc. with custom sizing, allows you to style your door, slabs, sidelights and transoms to your unique taste.
  • Pick your hardware and accessories: From handle sets to hinges, clavos and straps, Ostaco allows you to personalize every little detail while enjoying maximum protection and security. Take your door from boring to chic with interesting strike plate finish options that include antique nickel, satin nickel and Victorian bronze. Pair it with handsome ball bearing hinges in stainless steel, oil-rubbed bronze, brass, zinc or brushed nickel. You can also match your solid wood frame with a solid wood brickmould or choose from Ostaco’s Vinyl clad frames with a wide selection of vinyl brickmould options.
