Lawn care, garden maintenance, irrigation & hardscaping for Mount Sinai homeowners. Reliable, fully insured, and right around the corner — with free on-site estimates.
Green Horizon keeps Mount Sinai yards looking sharp, from the streets near the harbor to the quiet residential blocks across the 11766 area. We treat every property like it's our own.
Out in the North Shore, Mount Sinai homes deal with mature trees, shadier lots, and heavier seasonal leaf drop — so the right care really matters. We show up on schedule, do clean, careful work, and leave your yard better than we found it.
Whether it's weekly mowing, a fresh mulch job, a new sprinkler system, or a full backyard build, you've got one local, insured crew handling all of it.
