Choosing the right window for your Cos Cob CT home is a big decision.

Not only are windows literally your window to the outside world, but they are also one part of your house that can help save the world! It sounds dramatic, but really – energy-efficient windows are good for our planet, good for Cos Cob CT and the health of the nearly by Long Island Sound.

The benefits of having a quality home window system are countless. From managing sun reflection to their ease of operation, and of course, how they enhance the aesthetics of your homes’ interior and exterior.

I have lived and worked in the Tri-State area my entire life, back when I was a kid, working with my father, he taught me about the importance of working with great products.

When choosing replacement windows for your home, you have to consider the manufacture, the installer and the unique needs of your home or property.

Before I add any manufacturers line to GIANT’s offering, I do my homework. I took years looking for a window to call my own – one that would meet and exceed the needs of Connecticut area homeowners and I’ve got it! I am proud to call the Marvin window GIANT’s window of choice.
