Legacy Excavation is a Plymouth-based excavation and septic company. Its own site says it handles septic installation and repair, site preparation, utility trenching, drainage, grading, land clearing, and related earthwork across Plymouth, Barnstable, Bristol, and Norfolk counties; it identifies Joseph Derochea as owner and founder and describes the company as family-owned. The site also presents a Title 5 focus and Dig-Safe compliance claim.
The strongest through-line in the customer comments is practical site work done quickly and with care. A recent August 2026 reviewer described Joe as prompt, neat, thoughtful, and reliable. Earlier homeowners described a septic system passing inspection in less than five days, a septic tank replaced in two days, and an emergency farm water-line repair handled within two hours with the area left clean. Other reviews describe drainage and grading, driveway work, a retaining wall, and pool-site grading.
The written history is still short: 13 Google reviews dated from June 2025 through August 2026, with 13 of 13 reaching this read. The recent comments are positive and repeatedly mention communication, fair pricing, timely work, clean sites, and responsiveness. Before booking, ask how the quoted scope, permits, and Title 5 responsibilities will be handled for your particular site, and reconcile the company timeline: the site says it formed in 2025 while also describing a first backhoe in 2015 and 10 years in business.
Legacy looks most relevant for homeowners needing excavation-led septic, drainage, utility, grading, or site-preparation work in Southeastern Massachusetts. Confirm the exact scope, schedule, and current credentials for the job before signing.
