About Us


J&J Custom Builders was established in 1999. We are an owner operated general contracting company that perseveres in high-end residential construction. Long after many years of building and renovating homes in the Fairfield County area, a benchmark was etched. J&J was formed from hard work, determination, and the passion for perfection.

J&J Custom Builders is led by Joe Filanowski and John Costantini who are devoted to creating homes which become masterpieces of architect and client vision. Each home is finely crafted to the quality deserved. Whether contemporary or traditional, we apply the highest levels of attention to detail, foresight, material product, communication, loyalty cost, and finally, the team spirit that makes your construction experience a enjoyable venture. We are dedicated to serving our customer's needs, and our goal is 100% customer satisfaction. We strive to bring you the best in quality service. If something isn't right, please let us know.
