Empowering our Employees to deliver safe, quality solutions with on-time performance.


Our values are not just words on a page, we live them, measure our success by them, and continually evolve. All employees are proud to uphold our core values. These include safety, doing what is right, accountability, respect, problem solving, excitement for the future, embracing innovation and technology, and carrying the colors to honor our history.

Meaningful Work

Our craft and office professionals are the best in the industry, working tirelessly to deliver the highest quality mechanical and plumbing solutions every single day. There’s life at work and life outside of work. We strive to provide the best of both.


We provide employees the latest technology and resources to design, create, fabricate, and install complex mechanical and plumbing systems for all customers we serve. We pride ourselves on being adaptable and willing to change with the times.


Our technology drove the need for our business back in 1896 when the world needed a solution for health and sanitation to stay healthy. Our Founders responded by creating indoor plumbing systems. We continued to respond and expand to mechanical systems, HVAC, centralizing heating and cooling, and plumbing. Corrigan Company is one of the largest and most enduring St. Louis mechanical contractors, founded in 1896 by John F. Corrigan and today led by Dennis Corrigan as CEO.

Essential Services

We supply and support complex public health, sanitation, and heating and cooling so we can all live in comfort, with modern efficiency. We fabricate and assemble piping modules and other sub-assemblies in our own shop, delivering the greatest efficiencies, highest quality of craftsmanship and at a lower cost than assemblies on site.
