Lawn installation, seeding, aeration, weeding and poolside landscaping for Mount Sinai homes near the harbor.
Mount Sinai is on the North Shore in the Town of Brookhaven, around Mount Sinai Harbor and Cedar Beach, with newer neighborhoods off Route 25A and North Country Road. Lots are generous, many homes have pools, and North Shore soil and slopes add their own challenges.
Mount Sinai is one of our busiest search areas: lawn installation, seeding, aeration, weeding and poolside landscaping all show up here. We handle all of it, from building a new lawn to cleaning up the beds around the pool.
Weeds come back fast in thin lawns and bare beds. In the lawn, thicker grass is the best weed control, so overseeding matters. In beds, a clean-out, an edge, and 2-3 inches of mulch stop most weeds before they start.
