Welcome to Gilwin Company.

We are a manufacturer of premium vinyl window and door products suited to a wide range of applications and projects.

We have the experience and know-how necessary to assist you with a project of any magnitude. From a simple fixed window replacement in your home, to the installation of an entirely new series of hung windows with block and tackle support in a condo/apartment complex, our professional installation experts have years of field experience that allows them to provide confident, friendly service quickly and efficiently.

We sell a tremendous variety of window types, and since we manufacture all of our own vinyl products, each and every one of them can be customized to suit the specific needs of our clients. Nothing is too big or too small – just ask us for details!

Finally, and most importantly, we at Gilwin are ready to stand behind everything that we sell. From our windows to our accessories to the services that we provide homeowners, glass shops, window distributors and building developers/contactors across the state – we want you to know that your satisfaction is our primary concern.

If there’s ever anything we can do to ensure your satisfaction, consider it done.  As we are privately owned and operated we welcome suggestions for improvement in both product and procedures.
