High-performance windows and doors, personalized service.

At OKO, we have been importing the highest-quality European windows and doors since 2010. We collaborate closely with homeowners, architects, builders, and developers to seamlessly integrate our products into homes throughout New England.

European windows and doors perform to the highest standards of energy-efficiency, and compared to typical North American products, offer improved durability, security, and ease of maintenance. Our products are available with tilt-and-turn functionality, as well as other configurations, double or triple glazing, and many profile and finish options.

All products are fully custom-made to your specifications. Call us to learn more.
