About Wei's Windows & Doors
Over 23 years of excellence in the DMV area
Our Story
Founded over two decades ago, Wei's Windows & Doors has grown into the DMV area's go-to design partner for windows and doors. We started here, grew here, and have stayed here — working on homes across Bethesda, Rockville, Silver Spring, Alexandria, and DC. We're not a franchise or a national chain; we're part of these neighborhoods. When you work with us, you're working with someone who cares about how your home looks, because we drive past it too.
