About Us

Why should you choose Prime Windows?

Prime Windows is a Family Owned and Operated Company that installs the best products at affordable prices.

Our Goal is to make you a Customer For Life by respecting you, your family, and your home.

With over 50 years combined experience, Rich Sr., Rich Jr., and Dave Gagnon have built Prime Windows, LLC into a highly respected name in the replacement window industry in Connecticut and Massachusetts.

With our expert knowledge and use of our superior process of product installation, we are sure to make others seem like 2nd class.

Keep in mind that even the highest quality products can perform poorly if they are not properly installed!

We will not sell windows for the sake of selling windows. We are in the business to make you a well-informed customer who understands what we are providing and all the options available to you.

We want to ensure that you make a knowledgeable decision on this very important home improvement.

Many companies will try to be the lowest bid and sell an inferior product with inferior installation just to make a sale. We choose to show you our product and let you make an informed decision.

You can count on Prime Windows to do it right the first time because we do not subcontract our work. All our jobs are completed with factory-trained installers with the owners of Prime Windows involved on all jobs. If there were to be a problem, you can speak with an owner.


Once you see our products and our superior installation methods, you will know that Prime Windows, LLC is the right company for you.
