About East Coast Excavation & Site Work

East Coast Excavation & Site Work is based in Bow, New Hampshire, a town just south of Concord that blends suburban neighborhoods with larger residential lots that often require private septic systems. The company works across excavation, demolition, and septic services, which gives them a real advantage when a job involves more than just pumping a tank. Many septic issues, especially drain field failures or full system replacements, require serious earthwork that a general excavator can't handle the same way. Their location in Merrimack County puts them close to a wide range of residential and commercial projects.

Services & Process

East Coast Excavation handles the full range of excavation work that septic projects demand, from digging new tank locations to uncovering buried lids for inspection access. For septic-specific work, they can manage system installations, which involves grading the site, setting the tank, and laying out the drain field correctly according to state specifications. Their demolition background means they're also equipped to remove old or failed systems safely before putting in new ones. Site work services round this out, covering final grading and ground restoration once a septic project is complete.

Service Area

East Coast Excavation serves Bow and the greater Concord metro area, with reach across Merrimack County and into adjacent parts of southern New Hampshire. Towns like Dunbarton, Hooksett, and Pembroke fall within their typical working range for septic and excavation projects.

Frequently Asked Questions

Do I need a separate contractor for excavation and septic installation, or can one company handle both?
A company that does both, like East Coast Excavation, can manage the entire project without handing off between crews. This simplifies communication and often keeps the project on a tighter schedule.
How long does a full septic system installation take in New Hampshire?
From permit approval to finished site work, a typical installation takes one to two weeks of active work. The permitting process itself can add several weeks depending on the town and how quickly the engineer submits the design.
What soil conditions in the Bow area affect septic system design?
Bow has a mix of glacial soils, some areas with good drainage and others with ledge or clay that limits percolation. A soil test called a perc test or soil evaluation is required by New Hampshire before any system design can be finalized.
Can an excavation company help with a failed drain field?
Yes, drain field repairs almost always require excavation to expose the affected area, assess damage, and either repair or replace the leaching system. A company with both skills handles this more efficiently than separate trades working together.
What permits are required for septic system replacement in Bow, NH?
You'll need a state-approved design from a licensed engineer and a local permit from the town. New Hampshire's Department of Environmental Services oversees the approval process, and your contractor typically helps coordinate this.
What happens to the old septic system when a new one is installed?
The old tank is usually pumped out, then either crushed in place and filled with sand or removed entirely from the site. The choice depends on the tank material, its location, and the requirements of the new system design.
