Coyne Stair Construction
Serving residential clients across the Bay Area and Silicon Valley, Coyne Stair Inc specializes in designing, building, and installing custom staircases and rail systems. Based in Redwood City, the company handles a range of staircase styles, including curved, spiral, wishbone, elliptical, straight, and flared designs. Coyne Stair works with materials such as new and reclaimed woods, wrought iron, glass, and cables to create both contemporary and traditional looks. The firm also undertakes historical stair restorations, offering solutions tailored to period homes. Coyne Stair’s advanced shop uses computer-aided design (CAD), CNC cutting, and hand-crafted wood shaping methods to achieve precise, furniture-quality fit and finish. Their stair systems are assembled without pre-framing, reducing waste and minimizing environmental impact.
