Established in 1995, Jantek was determined to be an industry leader in the vinyl replacement window and patio door industry. The goal was to build a company that makes the window and patio door buying and installation process easy, trustworthy, and reliable.

The business model was built around manufacturing well made, custom sized, energy efficient replacement windows and sliding patio doors at a fair price to their customers. Jantek does not use hard-sell or deceptive sales tactics.

To do this, an expert team was assembled that included, engineers, product specialists, and installers. Manufacturing was streamlined to ensure their products were accurate and turned around quickly.
