Tom Howe Septic Systems is a family-owned Merrimack company focused on septic work, including installation, replacement, repair, pumping and drain-field work. BBB lists the business as operating for 57 years, while HomeAdvisor and Angi describe 58 years of experience. The written reviews are a dated mix. In an October 2023 Google review, a homeowner described a fast, successful septic-pump replacement and praised the explanation of the work. Older HomeAdvisor reviews from 2015 and 2020 describe septic-system installation, sewer connection, permitting, inspections and a prompt repair, while another 2015 reviewer praised the team's integrity and efficient work. There are also serious complaints to discuss before booking. A 2024 Google reviewer said communication and additional charges were unclear, described trash and glass left in imported fill, and said the yard restoration and seeding were poor. A December 2023 Google reviewer complained about a $40,000 project, unfinished cleanup and work beginning at a neighbor's property, ending with a recommendation not to hire them. They may be worth considering for septic installation, repair or pumping when the scope is clearly documented. Confirm the total price, change-order process, fill and cleanup responsibilities, and the exact work area before signing.
Great local company Great guys to work with And very conscientious
Tom and Keith installed a new septic tank and field at a house I purchased. They were nice people but more than frustrating to work with. Communication throughout the process was not very clear and additional charges were not communicated until after completion, even though discussed in the initial scope. The fill that they brought in had trash and glass throughout, that I’m still picking out almost a year later. They spread the loam to repair the yard, but left it for 2+ weeks and it mostly washed away with rains. Did a poor job seeding and left the yard worse than it began. They did me a favor cleaning up some brush around a barn, but failed to mention that they were pushing piles of old trash down the hill. The system they installed works, and I was hoping to have a great experience working with experienced contractors who came recommended, but I did not.
They changed $40,000 they haven’t cleaned up.. they started my Neighbors without cleaning my property up. Wouldn’t hire them again
Our septic pump stopped working and we needed help and weren’t sure where to get it. I read reviews in the Merrimack Forum and Tom Howe Septic Systems was strongly suggested. I called, and within the hour, Tom returned my call. Within the next hour, Tom and Keith were at our home to assess the situation. These gentlemen know how to troubleshoot and how to work hard. They ordered a new pump, installed it and we are now back in operation. They were so kind, and when we showed interest, explained exactly what they were doing and why. We received quite a valuable education. The honesty, value and hard work provided by Keith and Tom exceeds five stars. They are fantastic!
Tom Howe and his team did a tremendous job installing a new septic system in our home. Tom is a true professional and I would highly recommend him to anyone in the need of replacing there septic system.
