Retaining walls, stone patios, pavers, walkways, steps, and drainage for Armonk homeowners — from a licensed, owner-operated Westchester contractor.
Leo’s Construction & Excavation Corp. is based in Buchanan, in northern Westchester, and we serve Armonk and the Town of North Castle. We come out ourselves to walk your property, and Nestor, the owner, is on site for the work itself.
Many Armonk homes sit on larger lots with rock outcrops, mature trees, and grade changes — especially on the wooded roads off Route 22 and Route 128. Sloped yards are 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.
Natural stone and block walls for sloped yards, built with a proper base, drainage stone, and backfill so they don’t lean or bulge.
Stone patios, interlocking pavers, and stamped concrete that stay level through New York freeze-thaw winters.
Front walks and stone entry steps that are safe, even, and pitched so water doesn’t pool or ice over.
Fixing wet yards, pooling water, and runoff toward the house — at the source, not just the surface.
Concrete foundations and slabs for additions, sheds, and garages.
Cracked concrete, loose pavers, and stone foundations on older homes that need repointing.
Yes — all of Armonk and the Town of North Castle, plus nearby Chappaqua, Bedford, Mount Kisco, Pleasantville, and White Plains.
We’re based in Buchanan in northern Westchester. Call or text 914-330-3941 and Nestor will set up a time to walk the project. In most cases you get a fair price the same day. Estimates are free.
Yes. Sloped properties are a big part of our work — for example, the natural stone retaining wall, tiered patio, and steps we built on a steep yard in Highland Falls (see the before & after on our home page).
Some projects, such as taller retaining walls, may need approval from the Town of North Castle. We’ll let you know during the estimate if your project might need one.
