About Grantham Excavating

Built on Tradition. Focused on the Future.

Founded in 1945, Grantham Excavating was built on hard work, reliability, and a straightforward approach to getting the job done right. What began as a small, family-run operation has grown through decades of dedication to quality site work and excavation services throughout Lake County and Northern Illinois.

Today, under Brett Grantham’s leadership, the company continues to expand while staying grounded in the same values it was founded on. Every project, whether residential or commercial, is approached with careful planning, professional execution, and respect for the property and surrounding environment.

A Legacy of Dependable Work

Excavation is the foundation of any successful project. Grantham Excavating understands that proper preparation beneath the surface determines the long-term stability and success of what’s built above it. 

Our goal is to make the excavation phase smooth and predictable, so the rest of your project can stay on schedule.
