Custom Wood Windows and Doors

The G. W. Cernoch Works specializes in producing custom wood windows, window sash, interior and exterior doors and exterior traditional wood blinds.  We build for both new construction as well as reproduction work requiring period authentic millwork to maintain the historic or architectural integrity of a structure.  The range is from a simple single-light sash to windows and doors for a complete home or building. In addition, we can produce any incidental custom millwork you may need for your restoration, renovation, or new construction project.


While many projects may require only generic period profiles and details we have complete profile grinding equipment to produce custom cope-and-stick profiles and molding profiles in house.  We have an extensive library of door, window, and molding profiles available and have resources for custom tooling that may be required to produce or reproduce your project. Through constant analysis of period construction details, close examination of construction methods and awareness of the history of both hand and machine woodworking, we strive to produce products that are as authentic as possible.


Although some of our output goes into new construction, a large portion of our work is providing replacement window sash, windows, screens, and doors for older structures and for historic preservation projects.  Recent projects include:
