Sean Farrell Excavation, working out of Quincy, is the crew people call after a water or sewer line fails and they need someone who can dig a trench, replace a pipe, and put the yard back together without a mess left behind. The company says it has operated since 2000, running excavation, foundation, grading, storm drainage, water/sewer/septic, and pool-removal work across Quincy, Braintree, Boston, Milton, Weymouth, Hingham and much of the South Shore, with Sean Farrell himself named directly as the person overseeing jobs. Across 40 Google reviews from 2021 through mid-2026 - including six in the last six months - the pattern holds steady: a broken water main gets excavated and replaced within days, driveways and lawns get releveled and reseeded, and a specific crew member (James, Gary, Kathleen, Shane, Amos, Paddy) is named directly as having handled it well. Recent reviewers describe a thorough four-estimate comparison that landed on the company for its explanation of contingency plans, a same-day pool-removal quote executed in a tight backyard, and a water-meter job that turned into a full new water-line install without a hitch. Older reviews from 2022-2023 describe stump removal in tight, wire-crossed spaces, a driveway rebuilt into a patio and garden with a mid-job grade correction, and repeat work for at least one commercial client over several years. Not every job landed clean. A late-2024 reviewer gave 2 stars over a job site that reportedly went uncleaned for two months despite repeated calls and emails, and a separate 2024 reviewer alleged the company posted unauthorized no-parking signs on public streets during a job with no visible permit numbers. More seriously, the company's Better Business Bureau page - which otherwise shows an A+, accredited-since-2006 rating - carries one visible complaint alleging code violations, fraud, and defective structural work; no date or resolution is given here, so it's worth asking the company directly and checking the live BBB page before signing on for anything structural. For a straightforward water, sewer, or drainage dig, this is a company with a long, specific track record and an owner who shows up personally to scope the work - but given the BBB complaint, get the specifics on it before committing to anything bigger.

We were looking for a contractor to remove our in-ground pool, and are so glad we found Sean Farrell Excavation company in Quincy, Mass. They did a fantastic job for us- from the initial quoting process and planning, their expert logistics (our pool was in the backyard and not especially easy to access with equipment), and the highly professional crew who did the work - including Kyle and Freddie. They worked skillfully, fast and were very thorough. I would highly recommend Sean Farrell Excavation.
I highly endorse Sean Farrell Excavating for any forthcoming projects. What was initially expected to be a simple thirty-minute water meter replacement evolved into the installation of a new water line service, which was executed efficiently. I would also like to extend my sincere appreciation to Victor and Matthew for their exceptional professionalism, demonstrating outstanding expertise and representing your company in an exemplary manner. Once again, I wholeheartedly recommend their services. Furthermore, I would like to express my gratitude to Sean and acknowledge Kathleen's efforts.
They replaced our watermain last week. It was a long line and our soil was very rocky. They had to pull the old line out under a rock wall and through a bed with established trees. The team did an excellent job. They cleaned up thoroughly in our basement and fixed the lawn. They came in right on the quoted cost. Highly recommend.
I had an excellent experience with Sean Farrell Excavation when they replaced my water pipe. From start to finish, the team was incredibly professional—fast, efficient, and clearly knew exactly what they were doing. They completed the job without any issues, and what really stood out was how clean they left everything afterward. They were also genuinely kind and respectful of my property, which made a stressful repair feel easy and worry-free. It’s not always easy to find contractors you can trust, but this is definitely one I’d recommend without hesitation.
