Retaining walls, flagstone patios, pavers, stone steps, concrete and excavation for Cortlandt Manor homeowners — from a licensed and insured, owner-operated contractor right next door.
Leo’s Construction & Excavation Corp. is based in Buchanan, right next to Cortlandt Manor. We can usually come out quickly to walk your property, and Nestor, the owner, is on site for the work itself.
Many Cortlandt Manor homes sit on hillsides, wooded lots and rocky ground. Sloped yards are where stonework fails most often: walls lean, steps shift and water runs toward the house. We start every job with proper excavation, a solid compacted base and drainage that moves water away from your foundation.
Whether you want a flagstone patio with a fire pit, a natural stone retaining wall, new entry steps or a paver walkway, we give you a clear written estimate and a finished job you will be proud of.
On this sloped property in Cortlandt Manor we removed the old timber steps, excavated the hillside next to the driveway, and are building a new natural stone retaining wall, stone steps, and a patio by the deck — built on a solid base with proper drainage.






We built this backyard patio from irregular natural flagstone, with a round stone fire pit, a curved stone seat wall, and a natural stone retaining wall with steps up to the garden — all set on a compacted base so the stone stays level through New York winters.
