## The honest read

Celtic Landscaping, Inc. is a Massachusetts sitework and landscape contractor that has served the Boston area since 1987. Owned and operated by Steve Sullivan, the company describes itself as handling land-clearing, demolition, excavation, concrete form work and foundations, septic system installation, grading, drainage and landscape installations in-house, along with commercial snow services.

The Better Business Bureau independently lists the company as incorporated in 1987, with 39 years in business, and gives it an A+ grade, though the profile is not BBB accredited. Procore Construction Network's contractor listing describes the same concrete-and-excavation focus rather than routine lawn care, matching the company's own description of its work.

Before booking, it's worth confirming licensing directly with the state. Massachusetts registry records show the company's home improvement contractor licence (HIC #157617) is expired. BuildZoom separately lists additional licence numbers (132260 and 147512) under the company's name. The company's mailing address also differs across sources — a Duxbury, MA post office box on its own website, a Milton street address on Procore, and a Canton, MA street address on its BBB profile — all tied to the same (617) 908-5975 phone number, so confirming the current business address directly is a reasonable step.

Celtic Landscaping is best suited to homeowners with sitework needs — excavation, demolition, foundation and concrete work, septic installation or drainage — who want one contractor handling the earthwork rather than coordinating several trades, and who verify the state licence status before signing a contract.

**Strengths:**
- Long tenure — operating since 1987, confirmed independently by BBB's 39-year record
- In-house sitework — handles excavation, concrete and landscaping without subcontractors
- BBB A+ grade — Better Business Bureau rates the company A+

**Concerns:**
- Expired HIC license — state registry shows licence #157617 as expired
- Additional license numbers — BuildZoom lists numbers 132260 and 147512
- Address varies by source — Duxbury, Milton and Canton addresses appear

**Where sources disagree:**
- BBB grade of A+ appears on a profile explicitly marked as not accredited — two separate BBB facts, not one rating
- The company's own website and a state bonded-contractor list give a Duxbury, MA address, Procore's directory listing gives 567 Randolph Ave, Milton, MA, and BBB gives 121 Shawmut Rd, Canton, MA — all under the same (617) 908-5975 phone number
- BuildZoom's generic five-item services template (Agricultural Fences, Patios, Ornamental Metal Fences, Basement Remodel, Vinyl Fences) does not match the excavation, concrete and landscape services described by the company's own site and other directories
