Masonry & Hardscape in Harrison, NY
Built for Westchester winters.
Retaining walls, stone patios, pavers, walkways, steps, and drainage for Harrison homeowners — from a licensed, owner-operated Westchester contractor.
Owner-operated, not a big crew you never meet
Leo’s Construction & Excavation Corp. is a Westchester contractor based in Buchanan, and we serve Harrison, West Harrison, and Purchase, right next to White Plains. Nestor, the owner, walks your property for the estimate and is on site for the work itself.
Homes in Harrison range from older houses near downtown to larger properties in Purchase and West Harrison, and many sit on yards with grade changes, rock, and mature trees. That is where stonework fails most often: walls lean, patios settle, and water runs toward the house. We build every project with that in mind — solid base, proper backfill, and drainage that sends water away from your foundation.
Whether you want a new patio for the backyard, a safer set of entry steps, or a retaining wall to finally level out a hillside, we’ll give you a straight answer and a fair price.

Our simple process
Natural Stone Veneer on a New Building in Harrison, NY
We installed natural stone veneer around the base of a new multi-story building in Harrison — the storefront entrance, the corners, the columns, and the walls around the utility doors. Every stone was set by hand from the scaffold over a waterproofing membrane, so the finish looks clean and holds up to Westchester winters.

Harrison FAQ
Do you work in all of Harrison?
Yes — downtown Harrison, West Harrison, and Purchase, plus nearby White Plains, Rye, Rye Brook, Scarsdale, and Mamaroneck.
How quickly can you come out for an estimate?
Call or text 914-330-3941 and Nestor will set up a time to come out and walk the project. In most cases you get your price the same day.
Can you build on a steep or sloped yard?
Yes. Sloped and rocky properties are a big part of our work — retaining walls, tiered patios, and steps built with proper excavation, a compacted base, and drainage so everything stays level.
Will my project need a permit?
Some projects, such as taller retaining walls or new structures, may need a permit from the Town/Village of Harrison. We’ll let you know during the estimate if your project might need one.
Are you licensed and insured?
Yes. Leo’s Construction & Excavation Corp. is fully licensed and insured in New York State, and we guarantee our installation work.
