Our Connecticut Story
Founded in 2008, 203 Windows was born out of a simple observation: Connecticut homeowners were struggling with high heating bills due to old, inefficient windows. Our founder, Mike Johnson, saw families choosing between staying warm and staying within budget.
Starting with a single truck and a commitment to quality, we've grown to become one of Connecticut's most trusted window companies. What hasn't changed is our focus on helping Connecticut families save money on energy costs while improving their home comfort.
Today, we've helped over 5,000 Connecticut families reduce their energy bills and improve their homes. From historic colonials in New Canaan to beachfront properties in West Haven, we understand the unique challenges of Connecticut's diverse architecture and climate.
