About Us

Our Story & Commitment

Twenty-five years ago, childhood friends Sean McCormick and Jed Kenedy started doing side jobs together while attending college. After pursuing careers in other fields, they realized their true passion was building and renovating homes. In 2005, they founded Great South Bay Home Improvements with a simple philosophy: treat every customer as if they were our only customer. That mindset has shaped us into the trusted home renovation contractors we are today.

Communication is at the heart of every successful project. From the initial client meeting to the final walk-through, we prioritize clear, open dialogue. Our partnership ensures that an owner is always on-site, overseeing project management, coordinating with subcontractors, and maintaining quality at every stage. Behind the scenes, we also have an owner managing purchasing, scheduling, financials, and inspections. With our skilled team and reliable trade partners, we create a seamless, efficient, and detail-driven remodeling experience.

At Great South Bay Home Improvements, we are dedicated to making your vision a reality. From new construction to remodels, we take pride in delivering high-quality craftsmanship and personalized service. Your satisfaction is our greatest success, and referrals from happy clients continue to drive our business forward. When you work with us, you’re not just hiring a contractor—you’re gaining a team that truly cares about your home.
