Clifford Excavation, LLC

Clifford Excavation, LLC is a family-owned excavation contractor based in Harwich, on Cape Cod, offering site work that includes land clearing and grading, septic system installation, driveway installation, and rock and boulder retaining walls. Reviews from 2017 through 2023 on Angi and HomeAdvisor are consistently positive and repeatedly name Gary and Collin directly as hardworking and professional. A 2023 review described the crew clearing a lot of 30 stumps, grading the property, and installing a 185-foot stone driveway within a week of the first call. A separate 2023 review described Gary responding to an emergency septic situation caused by another company and staying in steady contact through the repair. Earlier reviews from 2017 through 2020 describe completed septic installations and driveway or grading work, with one customer noting the company can be hard to reach by phone despite being satisfied with the finished job. Two Google reviews from May 2026 describe a company truck driver behaving rudely toward a passerby on the road on separate occasions, including one account of an obscene gesture -- neither review describes a hired job or a completed project. Homeowners may want to ask directly about current crew conduct on the road. Separately, HomeAdvisor's own listing states the company does not offer emergency services or warranties, while Angi's listing for the same business states both are offered, and HomeAdvisor's services list includes septic cleaning even though its own description says it only installs septic systems and does not perform cleaning or pump-outs -- worth confirming exactly what is included before booking. For homeowners on Cape Cod needing excavation, grading, driveway, or septic installation work, the completed-job track record here is specific and strong; the main thing to verify going in is who from the crew will be on site day to day.
