Great Lakes Windows

We spent decades developing the highest quality vinyl replacement windows and patio doors, homeowners can ever find. We turned our attention to quality in 1981 when the founders of the Great Lakes Window brand discovered fusion welded frames and sashes that were used in Europe. This was quickly brought to their homes in Toledo, Ohio.

 

Having done almost 10 million vinyl replacement windows and doors, we have set our standards higher and have also been meeting them. We also continue introducing new products, adding new options and provide more support to homeowners coast to coast. We believe our products are as good as the people who make them. So we work with the best home improvement professionals to get quality replacement windows to your home. This is one of the many reasons Great Lakes Window products have an edge ahead of competition.

 

So come explore Great Lakes Window. Search for the windows and doors that celebrate your unique style and make your home sweet home, sweeter than ever.

Bethlehem Windows is locally

owned and operated.
