O’Leary Landscaping

O’Leary Landscaping describes itself as a full-service Cape Cod landscaping and irrigation company offering design, construction, maintenance, hardscape, lighting and irrigation for residential and commercial clients. The company says it has been in business since 1980 and recently merged with Lower Cape Irrigation, and it names Harwich, Chatham and Brewster as its service area. A 2025 Google reviewer said they had used O’Leary for over 20 years. That 2025 customer said that when the irrigation was turned on, Zach, the technician, moved some of the heads in the yard right away and made sure they were happy before he left. The same 2025 customer praised Krysta in the office and the fast online invoicing. A 2023 Google reviewer said O'Leary regraded the side and back yard and lowered and sloped a walkway and patio after a builder had put in too much fill and the cellar used to flood. That 2023 customer said the company charged a fair price and that afterward the rainwater went away from the house. A 2016 Houzz reviewer called the firm thorough and punctual and said it also provided plowing for the Cape Cod Theatre Company so it could open for business after snow. The Better Business Bureau gives it an A+ grade. Houzz lists licence number MCLP#1561 and an Angie's List Super Service Award for 2015 and 2016.
