O’Neill Landscaping has been serving coastal New Hampshire and southern Maine since 1994.

What began with a mower, a trailer, and a commitment to doing things the right way has grown into a full-service landscaping company trusted for thoughtful design, expert craftsmanship, and dependable year-round property care.

Founded on hard work, integrity, and a deep knowledge of horticulture, O’Neill Landscaping brings decades of hands-on experience to every project—from custom landscape construction and outdoor living spaces to meticulous property maintenance, irrigation, outdoor lighting, and snow & ice management.

We believe exceptional landscapes come from more than just equipment and labor—they come from experience, attention to detail, and a genuine commitment to our clients.

Whether we’re transforming a backyard, maintaining a coastal estate, or keeping properties safe through New England winters, our goal remains the same:

to care for your property like it’s our own.
