Illinois Electrical Office
Strategically located in Granite City along historic Route 3, Guarantee Electrical Company's Illinois office supports the growth and expansion needs of southern and central Illinois. From US Steel's ongoing operations to Southern Illinois University-Edwardsville's ever-expanding campus, the "eastern suburbs" of the St. Louis metropolitan region continue to grow and thrive. New infrastructure, hospitals, educational institutions, urban transportation systems, wastewater treatment centers and entertainment facilities have brought continued opportunity to the Guarantee Electrical Company Illinois team. A smaller presence than our sister office across the river in St Louis does not diminish our professionalism or the high level of electrical contracting expertise we bring to Southern Illinois. It just makes us easier to get to know.
