Hamm Septic Services is a Hudson-area septic contractor serving southern New Hampshire, with the company saying it has operated since 1958. Its own site describes residential, condominium, and commercial septic-system repair and maintenance, including tank pumping, riser and cover-extension work, pump-station troubleshooting and installation, excavation, filter work, jetting, camera locating, and sewer-line repairs. The company also describes itself as veteran-owned and operated and says its staff is trained, licensed, and insured, with a certificate of insurance available on request.
Customers consistently describe dependable septic pumping and tank cleaning. Recent reviews praise technicians for arriving on time, communicating by text, working efficiently, explaining the system, and leaving soil, grass, mulch, and work areas tidy. Reviewers also describe riser installation, filter cleaning, tank-cover work, and long-running relationships with the company, including customers reporting 20 to 40-plus years of use. Google shows 4.8 stars from 188 ratings, while BBB lists an A+ grade; that BBB grade is not a customer-review average.
There is one sharply negative review alleging unauthorized extras on a bill and an argumentative response when questioned. Other reviewers mention a three-day delay returning phone messages and one appointment that ran late, although the work was completed well. Before booking, confirm the exact scope, any added work or materials, pricing, arrival window, and which technician will attend. Hamm appears best suited to homeowners and property managers seeking recurring pumping, septic maintenance, and related repair or excavation work across its stated southern New Hampshire service area.
