Founded in 1902, Guarantee Electrical first showed the world what electricity could do by illuminating the 1904 World’s Fair, and then “guaranteeing” that it would work for the duration of the event at a time when electrification was still in its infancy. Today, we continue to build our legacy as a national leader in electrical engineering, preconstruction, electrical construction, building management systems, cutting edge electrical construction technology and methodologies, and project management. 

With four regional offices, Guarantee Electrical Company has the capability to meet any owner or contractor's project demands.   

As a member of the Federated Electrical Contractors (FEC) best practices network, Guarantee is able to provide support beyond our core regions by partnering with other electrical contractors across North America.  The FEC is an international network of leading electrical contractors dedicated to safely providing clients with the highest quality electrical and low voltage systems at competitive pricing, regardless of geographic location.
