About Global Window Systems

Fenestration Concierge Services Tailored to Exceed Clients Expectations.

Drawing on their roots in Poland and the East End of Long Island, Kris and Tom combine European craftsmanship with local expertise to bring beauty, performance, and precision to every project.

Their passion for design is matched only by their commitment to community from serving as Fire Chief of the Flanders Fire Department to supporting the Riverhead Polish School and local community initiatives.

Together, they’re redefining what it means to furnish and install windows and doors transforming complexity into clarity, and vision into reality.
