Lawn seeding, renovation, landscaping and backyard design for Port Jefferson and Port Jefferson Station homes.

Port Jefferson ranges from the hilly village around the harbor and the Bridgeport ferry to the flatter, newer neighborhoods of Port Jefferson Station. Two very different kinds of yards, and we work both.
In the village, it's steep lots, older homes and tight spaces. In Port Jefferson Station, it's lawns that need seeding or renovation and backyards ready for a plan. Lawn seeding and renovation are the top searches across both.
On Port Jefferson's steep village lots, equipment access drives the plan. We use smaller machines and hand work where needed, and favor planted slopes and terraced beds over lawn on banks that are hard to mow.
