Welcome to Optima Windows and Doors, Whitby's trusted provider of premium replacement windows and entry doors.

Why Whitby Homeowners Choose Optima Windows and Doors
Whitby holds a special place in Durham Region as the seat of regional government and a community rich in history. Named after the seaport town in Yorkshire, England, Whitby was incorporated in 1855 and served as a vital transportation hub. The town was also home to the legendary Camp X, a WWII spy training school, and the 1958 World Champion Whitby Dunlops hockey team. Today, Whitby seamlessly blends this heritage with modern suburban growth.
Whether you own a heritage home near Downtown Whitby's historic Brock Street, a family home in established Williamsburg or Rolling Acres, a waterfront property in Port Whitby, or a newer build in rapidly-growing Brooklin or Taunton North, your windows and doors must perform in Ontario's demanding climate. Lake Ontario influences temperatures in southern Whitby, while northern areas experience the full range of Canadian seasons.
Our vinyl windows are manufactured locally using authentic German engineering principles. Every window features multi-chamber frame construction, Low-E glass coatings, and argon gas fills that exceed ENERGY STAR requirements. The result? Whitby homeowners report energy savings of 25-35% on heating and cooling costs after upgrading to Optima windows.
