Precision Manufacturing
Our Story
What began as a small workshop in Chicago has grown into one of North America's most trusted architectural door and window manufacturers.
Founded in 1999, Precision Door & Window Manufacturer was built on a simple belief: that every building deserves doors and windows as thoughtfully engineered as the architecture they serve. Over the past 25 years, we've grown from a team of five craftsmen to a 300+ person operation, serving architects, builders, and homeowners across 30 countries.
Our manufacturing facility combines German CNC precision machining with Italian finishing techniques — all guided by American quality control standards. Every product that leaves our factory is the result of generations of accumulated expertise and a culture that refuses to compromise.
