For almost a quarter century, Certified Windows and Doors has been helping the Essex County community replace their windows and doors. We've been family owned and locally operated since our inception. Along the way, we've made a lot of friends, grown from our mistakes and continue to offer the industries most incredible lifetime warranty on service and materials. We're not one to brag about ourselves. Our customers do it for us. Thanks to one and all who've made Certified Windows and Doors a household name in Essex county and the surrounding areas! <3
