Affordable Excavation for Residential & Commercial Use

Excavation is the foundation of every successful construction or underground utility project. Whether you’re installing a new sewer line, repairing a broken water main, or grading land for a building foundation, professional excavation services ensure safety, precision, and compliance with local regulations. At St. Pierre Plumbing & Heating, we specialize in affordable excavation services for homeowners and businesses throughout New Hampshire.

What Are Excavation Services?

Excavation involves the process of removing earth, rock, or other materials to create space for construction, underground pipes, utility lines, drainage systems, or landscaping. It’s a critical step that lays the groundwork for plumbing, septic, electrical, and structural projects.

We offer both light and heavy-duty excavation, depending on the size and complexity of the job.

Our Excavation Services Include:

Sewer Line Excavation

If your sewer line is damaged, clogged, or collapsed, we perform trench or trenchless excavation to access and repair the line safely and efficiently.

Water Line Excavation

Leaking or outdated water mains often require digging to replace or upgrade pipes. We work with minimal disruption and ensure clean, safe results.

Septic System Excavation

We provide digging for septic tank installations, replacements, and leach field repairs. We ensure proper placement, slope, and drainage for long-term performance.

Grading and Site Preparation

Need a level base for construction or landscaping? We handle land grading, soil removal, and slope adjustment to prepare your site for the next phase.

Foundation and Trench Excavation

We dig trenches and footing foundations for homes, garages, sheds, and utility lines—all with precision and adherence to code.

Drainage System Installation

Proper drainage prevents water damage and soil erosion. We excavate for French drains, catch basins, culverts, and other stormwater solutions.
