Customer Focus

There is no better testimony to our customer-centric approach than to receive the highest awards in our industry.  Guarantee Electrical Company has won more Associated General Contractors of Missouri Construction Keystone Awards than any other electrical contractor in St. Louis.  Likewise, several of our projects have won ASHE Vista Awards, Willis Excellence in Construction Safety Awards, Federated Electrical Contractors Awards for Safety and many more.

Community Outreach

The best outreach efforts are the ones that yield results in ways that feel inevitable. We not only financially support these efforts but likewise devote time and sweat to the causes.  Organizations we support, like Pedal the Cause, Kidstruction and Hard-Hats With Heart have missions that fit well with our profile as a specialty services supplier to the construction industry.  Additionally, Guarantee Electrical is intimately involved with other missions including Flags of Valor, United Way, and Big Brothers, Big Sisters.

Diverse Talent

Our team of more than 500 employees includes engineers, electrical designers, project managers, safety directors, IBEW craft workers and office staff. They bring "Many Strengths" to our team from all different walks of life.

Social Responsibility 

We view social responsibility in several unique ways.   

  • As a longtime early adopter of construction technology, Guarantee Electrical prides itself on our commitment to "construction sustainability" including Leadership in Energy and Environmental Design (LEED), Building Information Modeling, Trimble® MEP software, electrical prefabrication, just-in-time delivery project management and much more.
  • Employee health & wellness is a critical part of our social responsibility.  Outside of offering a wide range of benefits including health, dental, long-term disability insurance, paid holidays and vacation, we have a full gym onsite offering employees the opportunity to workout at their convenience.
  • We work with many different groups to help educate elementary and high schools through educational and mentorship programs. 

Team Camaraderie

We believe in having fun!  Annually we take time out to enjoy some fun including Halloween contests, an annual Holiday party, an annual kickball game, team cycling in support of Pedal the Cause, sporting clays with customers, Cardinal baseball games and much more!

Employee Stock Ownership Plan (ESOP)

Guarantee Electrical Company employees are more than just paid workers. They’re also part owners in Guarantee Electrical Company, thanks to our Employee Stock Ownership Plan (ESOP). Successfully launched on October 1, 2005, and successfully completed on October 1, 2015, the ESOP was designed to help grow the company by facilitating the transfer of company ownership from the founding Oertli family to our employees. Our ESOP is 100% company funded and is part of Guarantee’s retirement benefits package.
