Excavation and Site Prep with Owner-Led Precision
We provide grading, trenching, and small-scale excavation with the same care and quality that’s made us Southern New Hampshire’s trusted paving contractor for over 45 years.
Excavation Services for Driveways, Foundations, Utilities & More
Whether you're preparing to pave, installing a new utility line, or regrading a property for better drainage, excavation is the first step to getting it done right. Poor site prep leads to long-term problems — from standing water and cracking pavement to unstable foundations. At Cornerstone, we take the time to understand your property’s layout, slopes, and drainage needs before we ever break ground.
Joe Stanley personally manages every excavation project, working with precision equipment and a skilled crew to make sure every cut, trench, and grade is executed to last. We don’t rush the prep — because what’s beneath the surface determines the quality and longevity of everything that follows.
Our excavation services are ideal for:
- New driveway and roadbed installation
- Building and garage foundations
- Drainage correction and grading
- Trenching for pipes and utilities
- Small-scale commercial site work
