No state license for this trade. New Hampshire doesn't license or register demolition & excavationbusinesses, so there's no state registry to check. That's true of every demolition & excavation business in the state, not a mark against this one. Insurance is self-reported.

Derry Septic Service, Inc. is a family-owned and operated septic company based in Londonderry, New Hampshire, run by the Ball family (Richard and Lynn, per BBB) along with other family members reviewers name directly, including Matt, Mike, and Jason. The business has been operating since 1981, and at least one long-time customer reports having used them for 38 years. Reviewers across five years, from 2021 through 2026, consistently describe fast, dependable emergency response: multiple accounts describe technicians pumping tanks and diagnosing clogs the same day or the day after an emergency call, even in winter conditions with frozen ground. Several reviewers specifically praise the company's honesty over upselling — one customer recounts being told a full inspection wasn't necessary after Lynn took the time to understand the actual issue, and another contrasts Derry Septic favorably with larger, consolidated septic operators. A recurring theme is septic inspections tied to real estate purchases, with several buyers describing thorough evaluations of a leach field or tank ahead of a closing deadline. The record is unusually uniform: 36 stored reviews spanning 2021 to 2026 are all five stars, with no negative reviews on file, and Google separately shows an even larger pool of 66 ratings. The consistency of detail — specific technician names, specific fixes such as clog snaking, pump replacement, and leach field evaluation, plus repeat customers describing decades of use — supports a genuine, established local reputation. New Hampshire does not license septic installers or excavation contractors as a state-registered trade, so there is no state credential to check here; BBB lists the business as not accredited and without a customer rating, which is common for long-established local firms that haven't sought BBB accreditation. Because every available review is positive, there isn't a documented pattern of complaints to weigh against the praise. Homeowners can expect a well-established, communicative family operation for routine pumping, inspections ahead of a home purchase, and emergency repairs, with a track record long enough that some customers have relied on them for decades.
