Electrical Contractor | St. Louis Electrician | Guarantee Electrical Company


ST. LOUIS, MO April 16, 2021 – St. Louis based electrical contracting firm Guarantee Electrical Company announced Colorado Springs based Berwick Electrical Company will be merging onto their platform. The merger will be finalized on June 1. As Guarantee’s newest business unit, Berwick joins existing operations in Colorado, Missouri and Illinois. The combined companies will have total revenue of $250,000,000 and 750 total employees.  

When the merger is complete, Berwick Electric will become an independently operating business unit within Guarantee Electrical Company, while continuing to do business as Berwick Electric Co. Its operations, leadership, management and team will remain intact. Third-generation owner Doug Berwick will retire upon completion of the transaction. 

“We’ve worked hard at Guarantee to build a platform for this exact type of partnership,” said Rick Oertli, Chairman and CEO of Guarantee Electrical Company.  “Guarantee’s ownership and governance structure, coupled with the support services in place, provides a pathway for compatible companies looking for a stable long-term succession plan. The Berwick team’s solid reputation, culture and capabilities make for a great fit. We are thrilled to have them on board.”

Both companies have been long-time partners within the Federated Electrical Contractors (FEC) peer group and have aligned company cultures. Having shared an operational footprint in the Colorado market for more than 15 years, the companies have come to understand and appreciate what each has to offer.  

“I’ve admired Guarantee for a long time. We share common culture, values and approaches to both operational excellence and the wellness and prosperity of our teams,” said Doug Berwick. “Connecting my Berwick family to the Guarantee team is the culmination of a lifelong goal of ensuring Berwick Electric will live on for the next 100 years.”
