Stanek Windows Our Story

Stanek® brand vinyl windows and patio doors are made exclusively by Great Day Improvements, LLC,a residential and commercial manufacturer and installer of windows and doors. We custom design and custom manufacture all our products specifically for you and your home. Because we make your windows in our own state-of-the-art manufacturing facility in Ohio, we can ensure exceptional quality from start to finish. Non-standard and large openings are no problem.

At Stanek Windows, we work with you to help you understand the window industry — what to look and watch for in energy-efficient windows. We take the time to get to know your specific needs before we ever recommend a solution.

Our line of beautiful Stanek windows offers outstanding strength and unbeatable insulation, backed by certified performance. Stanek windows deliver cutting-edge performance along with beauty, high quality and exceptional energy efficiency! Our new triple-pane windows exceed ENERGY STAR® ratings in all climate zones across the United States and are among the most energy-efficient products.

You can get a new window anywhere; but Stanek windows deliver benefits far beyond style. The energy-efficient windows and patio doors are engineered to outperform the elements and the competition. To reinforce our commitment to quality, we independently certify and test our windows and patio doors. We offer advanced thermal protection that increases energy efficiency and lowers energy bills. With Stanek Windows, you will have peace of mind knowing you have made a beautiful choice with lifetime performance.

In addition to Stanek brand vinyl windows and Patio Enclosures brand sunrooms, we also are a dealer of ProVia® Entry Doors.
