A customer describing a failing septic system says Steve Sarette & Son Excavation took it from inspection to a replacement system within two weeks. In that April 2026 Google review, Tim visited that afternoon, took the old plans back to the office, prepared a quote and new plans, and submitted them to the authorities. The customer says the crew removed shrubs and old tar before installation, left the site ready for seeding, and finished within the quoted amount.
The company describes itself as a family-owned excavation business in Goffstown, New Hampshire, handling residential, commercial and municipal work. Its stated area includes Goffstown, Bedford, Hooksett, Merrimack, Manchester, New Boston, Dunbarton, Derry, Amherst and Londonderry. It advertises septic design and installation, driveway grading, ledge removal, sewer and water connections, site development and drainage. The company claims 30 years in business; BBB lists a 2001 business start. Google shows 4.9 stars from 64 ratings, and BBB gives it an A+ grade without accreditation. BBB also lists NHDES Subsurface Systems Bureau licence number 03898.
The yard work customers describe goes beyond digging a hole. A June 2026 Google reviewer says the crew cleared an overgrown area, removed stumps and large boulders, reused boulders in a retaining wall, and finished with grading, mulch and stone in requested areas. That customer praised the schedule and price. Another April 2026 reviewer described a new sewer pipe from the house to the property line and praised Mike's involvement from beginning to end.
Older customers described the work around a septic replacement as well as the installation. In a June 2025 review, one said Sarette handled design, permits and inspection. An August 2024 reviewer described a drain-field and yard-extension project with limited access: Tim walked the property before quoting, and the customer praised communication and care for the property. A March 2024 reviewer said the crew replaced a septic tank and leach field at a four-bedroom residence while protecting the driveway and adjacent landscaping.
Prices have drawn different comparisons without a complaint about the work. In a March 2025 review, a customer said Sarette's quote was slightly higher than another comparable quote, but chose Tim after he arrived with their septic plans and explained the job. A September 2022 reviewer described stump removal and grading completed on time and on budget, with direct consultation during the project.
