Andrew Jarocz
From a young age, Andrew Jarosz was immersed in the world of steel and hard work. His journey began at just 14 years old, welding side by side with his father, a Polish immigrant who came to the U.S. in 1974 and founded Jarosz Welding in 1986. What started as a father-son trade evolved into a lifelong commitment to craftsmanship, resilience, and growth.
After graduating from Catholic High School in 1990, Andrew joined the family business full-time. He gained early experience welding aircraft parts for major aerospace companies, including Pratt & Whitney, before transitioning into structural and architectural steelwork. His deep understanding of the trade and hands-on approach led him to rebuild properties, take on subcontracting work, and eventually manage large-scale fabrication projects.
In recent years, Andrew Jarosz launched JWC Steel and made major investments in equipment and capabilities, including a 150,000-pound beam line and industrial cranes. Today, he operates two thriving steel fabrication companies—CWJ Deck and JWC Steel—serving general contractors throughout Connecticut and the Greater Boston area. His team produces steel stairs, railings, porches, balconies, and fire escapes for residential and commercial projects. Running two companies allows Andrew to diversify services and maintain flexibility in a competitive industry.
Beyond the shop floor, Andrew is deeply committed to developing his workforce. He’s provided opportunities for apprentices from all backgrounds, including individuals from state rehabilitation programs and international workers seeking a fresh start. He believes in fairness, personal accountability, and continuous improvement—for himself and for his team.
Andrew Jarosz continues to expand operations, explore new markets, and invest in his craft. With an eye on growth and a foundation built on family, discipline, and trust, he brings not just steel structures to life, but opportunities for those willing to work hard and rise with him.
