Sweeney Excavating Corp.

Sweeney Excavating Corp. is a Bourne-based crew that spends its days on the parts of a home project buried underground or under a yard — septic systems, site grading, retaining walls, drainage, and lot prep — across the towns ringing Plymouth, Falmouth, Kingston, Pembroke, Marshfield, Norwell, Sandwich, Barnstable, and Duxbury. It's a one-owner operation: BBB records list it as a sole proprietorship run by Michael J. Sweeney Jr. There's a wrinkle in how long it's been at it. The company's own site dates its current run to 2014, while BBB's file puts it at 18 years in business — two different starting points that don't reconcile, and worth asking about directly. Where the read is clearer is how the work lands with customers. Its Google rating sits at 4.9 stars across 28 ratings, and BBB gives it an A+ grade with no complaints on file, even though the business has never applied for BBB accreditation. The numbers behind that are modest rather than deep — there isn't a large bank of recent, detailed reviews to draw on — but nothing available runs against the grain. The company describes itself, on its own site and in outside listings, as fully licensed and insured for excavation work in Massachusetts. That's Sweeney's own claim rather than something independently confirmed here, so it's worth having them show current documentation before signing anything. For septic work, grading, drainage fixes, or a retaining wall in the South Shore towns it lists, Sweeney is a small, owner-run option with a clean complaint record so far. Given the thin review history and the founding-date mismatch, it's worth a short conversation about how long Sweeney has actually been doing this work, plus getting current license and insurance documentation in hand before the job starts.
