Missouri Electrical Office

As one of the top electrical contracting companies in Missouri, our St. Louis office is where it all began in 1902 and continues to be our corporate headquarters.  The name “Guarantee” resulted from the unprecedented one-year installation warranty the seven founders offered World’s Fair organizers to light the 1904 World's Fair.  Due to its central location, St. Louis and in fact, Missouri, is among the fastest growing regions with global brands such as AB-InBev, Enterprise Holdings, Centene Corporation, Nestle, and many more calling Missouri home.  With a robust tourism business, Missouri is a thriving state that continues to grow and offers an exceptional quality of life. Our team of electrical contractors has a firm knowledge of the uniqueness that is the "Show-Me" state.  For more than 115 years our approach has been to take on projects in a variety of industries -- leading in healthcare, education, industrial, data centers and more. We partner with you to offer our "One Guarantee" - a high quality, collaborative and honest approach to your next project and reliable support for your future growth.
