Genex Window — Windows & Glass · General Contracting in Warren, MI
Genex Window is a Michigan-based manufacturer and installer of custom-built vinyl replacement windows for residential homes.

We specialize in double-hung, casement, sliding, picture, bay and bow windows, as well as patio doors. Every unit is built to order using high-performance glass, reinforced vinyl frames, and premium hardware.
