C. Mayo Excavating, Inc.

What exists on C. Mayo Excavating is paperwork rather than customer stories. Ashland's town site listed the Clark Street company among septic installer permits in a December 2024 posting, and Sherborn's records include it among Disposal Works Installer Permit renewal applications alongside two other installers; a December 2023 Sherborn listing carries the company with its own permit number. That points at the trade plainly enough — septic system installation and the excavation work that goes with it, in the MetroWest towns around Ashland. LinkedIn profiles from current and former staff show an office side too: project management, billing and bookkeeping, so this is not a one-truck operation. No customer has written about the work anywhere, so there is nothing yet to judge the finished jobs by. If you are weighing them for a septic install or site work, ask which towns they have installed in recently and for owners you can call, confirm the installer permit is current with your own board of health, and get the scope and the price on paper before anything is dug.
