Welcome to Wintek

Featuring Northstar, Duxton, Provia, Sunrise, and Wincore products.

We are located in West Michigan and offer energy efficient vinyl and fiberglass windows and sliding doors that are manufactured to the highest standards. Our broad knowledge of the construction industry and building codes along with in depth knowledge of the products we sell, position us to be uniquely qualified to help you select the best window and door products for your next building or replacement window project.

We provide prompt window quotes from your prints or on-site measuring can be requested to insure your windows are ordered to your exact specifications.


New construction windows and replacement windows are made to order. There are no “stock” sizes, so they can be ordered in increments of 1/16″.

Deliveries in and around the Grand Rapids area are scheduled around your installation time frame. We can address most service issues ourselves, which eliminates waiting for a manufacturers service technician.
