## The honest read

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.

**Strengths:**
- Emergency responsiveness — Gary praised for quick, communicative emergency service
- Detailed site work — stump removal, grading, and driveway installs praised by name
- Repeat customers — one reviewer calls them a long-time, regularly used contractor
- Named crew praise — Gary and Collin repeatedly singled out as hardworking

**Concerns:**
- Recent driver complaints — two May 2026 Google reviews cite rude conduct on the road
- Reachability — one reviewer noted the company can be hard to reach by phone
- Cross-platform amenity conflicts — directories disagree on emergency service and warranty availability

**Where sources disagree:**
- HomeAdvisor's own 'Services we offer' list includes 'Septic Cleaning' while its About text explicitly states the company does not provide septic pump-outs or cleaning -- a contradiction on HomeAdvisor's own page.
- HomeAdvisor states no emergency services and no warranties are offered, while Angi's profile for the same business states both are offered -- the two directory mirrors disagree on amenities.
- The January 2020 4-star review appears on Angi attributed to 'Francis M.' and on HomeAdvisor attributed to 'Robertal L.' with identical text and date -- the same review carries two different author names across platform mirrors.
- Google's 3.4-star average (5 ratings) is dragged down by two very recent (May 2026) 1-star reviews about a truck driver's road conduct, in contrast to Angi's 4.8-star and HomeAdvisor's 4.9-star averages built from an earlier, larger set of customer-hire reviews (2017-2023).
