Speakman Excavating LLC is a family-owned excavation and septic contractor based at 235 Great Western Rd in South Dennis, working what its own site calls the Plymouth-to-Provincetown corridor. The advertised work is septic pumping, Title V inspections, septic and sewer tie-in engineering and installation, site work and demolition, with four licensed septic inspectors said to be on staff. Septic and sewer work is what customers actually describe. A July 2026 reviewer had a tight tank installed behind a Plymouth beach cottage and credited Charli with guiding them through the process and negotiating an easement with a neighbour; a February 2026 reviewer said two other septic companies had refused a complicated install and that Charlotte and her team met every deadline needed to close a home sale through a snowy winter. A December 2025 reviewer used them for a septic inspection and repair quote and praised quick responses and a clear report. The accounts are unusually specific about people and follow-through. A May 2025 reviewer described yard excavation and a hatchway installation where Miguel worked to their timeline and returned within two hours to re-fill and compact settled ground after heavy rain. In a 2023 review a homeowner said the company returned with excavating equipment to fix a problem on a septic system it had installed more than six years earlier. Outside the review platforms the name shows up in municipal work: a Bourne town engineer, quoted by capenews.net in August 2026, said the Dennis-based contractor did "a lot of work in a very short amount of time"; the Nantucket Land Bank's $784,250 Easton Street rain-garden project was built by the company as sole bidder; and the Marshfield Housing Authority took its bid as lowest of nine for a sewer extension and later certified substantial completion on a state septic replacement project. Two things to raise before booking. A 2022 Google reviewer wrote that a bulkhead was installed wrong, that the company would not fix it and that they expected to sue in small claims court — the only negative on file, and it stands unanswered here. And the licensing picture is untidy: BuildZoom lists a Home Improvement Contractor licence plus eight others, but the records it shows are one Newton general-contractor licence marked active-but-unverified with a December 2022 expiry and five inactive or cancelled entries, and its owner field names William Buchanan rather than the Speakmans. Ask directly for current HIC and Title V inspector credentials, in writing, and for the licence numbers that cover your specific job.

Speakman did an excellent job installing a tight tank behind my beach cottage in Plymouth. I worked with Charli, who made the whole process easy — I didn’t know much going in, and she guided me through every step. The install required coordinating with my neighbor through an easement, and Charli handled that beautifully, communicating clearly with both of us throughout. A pleasure to work with. Highly recommend!
Speakman Excavating goes above and beyond for their clients. I had two septic companies prior who were not willing or able to take on a complicated septic install. Charlotte and her team came in and saved the day. They met every deadline we needed in order to complete the sale of the home even with the snow we had this winter. I have zero reservations recommending them.
Worked with Charlotte and Miguel for a septic inspection and potential repair. Cannot stress how helpful they were, stellar service from start to finish. Quick responses and clarification when needed, scheduling the work and providing the report.
Contracted with Speakman for yard excavation/flattening and a hatchway installation. Miguel handled the job from start to finish. Job was done exactly as expected. Miguel worked with my timeline to insure I could have the exterior door at the bottom of the hatchway into our basement framed and installed within 24 hours of him installing the hatchway. Some settling of fill around the hatchway after some heavy rain two days later and Miguel was there within 2 hours to fill and compact. Another small amount of settling happened in front and he was there to fill and compact within two days (I texted him on Sunday afternoon of Memorial Day weekend and he arrived before 8:30AM in Tues to fill and compact. I do not hesitate to recommend doing business with Speakman Excavating based on my positive experience.
Speakman installed our septic system over 6 years ago. We just recently had it pumped and an issue was discovered. We informed Speakman, who them came to our site with excavating equipment and resolved the issue. Exceptional customer service.
