Custom Wood, Clad & Steel Windows and Doors in Arlington, WA
Founded in 1982 by two Pacific Northwest general contractors, Quantum has evolved from a small custom wood window manufacturer into an industry leader in architectural wood, clad, and steel fenestration solutions. Our journey began with dissatisfaction over mass-produced windows, driving us to create products that match the craftsmanship of the homes we served. Over four decades, weve expanded our offerings to include clad and steel systems while maintaining our commitment to quality, sustainability, and innovation. Headquartered in Arlington, WA, our locally owned business combines traditional artistry with modern technology to deliver products that meet the demands of architects, builders, and discerning homeowners.

We prioritize environmentally responsible materials and processes, ensuring our windows and doors not only enhance spaces but also minimize ecological impact. With international reach and a focus on continuous improvement, Quantum remains dedicated to exceeding expectations through precision engineering and timeless design.
