Steele Group Services
Excavation
Steele Group delivers precision excavation and grading services across Long Island, from residential foundations to large-scale commercial sites. Our experienced operators and modern fleet handle everything from topsoil stripping and land clearing to deep trenching and sub-grade prep. Whether you’re building in Oyster Bay, Smithtown, or Riverhead, we know the soil, slopes, and permitting conditions unique to Nassau and Suffolk County.
Foundations
Every great structure starts with a solid base. Steele Contracting provides foundation excavation, footing prep, and backfilling for residential and commercial construction throughout Long Island. Our precision ensures your foundation is level, stable, and built to last — even in coastal and high-water-table environments.
Rock Revetments
Protecting waterfront properties requires expertise and the right equipment. We specialize in rock revetment, seawall reinforcement, and erosion control solutions tailored for Long Island’s coastal zones. Our team sources durable rock, installs engineered revetments, and works within DEC and town regulations to secure your shoreline against storms and tides.
Retaining Walls
From small landscape walls to heavy-duty structural systems, Steele Contracting designs and builds retaining walls that hold strong and look great. We work with concrete block, boulder, or timber systems to stabilize grades, prevent erosion, and enhance property aesthetics. Proper drainage and compaction ensure your wall performs for decades.
Drainage
Proper drainage is key to protecting property and pavement. Steele Contracting installs drainage systems, culverts, and dry wells that meet town and county standards. We analyze site elevations and water flow to prevent pooling, flooding, and foundation damage — essential for Long Island’s diverse soils and coastal climates.
Septic Installation
We provide full septic system installation and replacement services throughout Long Island, ensuring compliance with Suffolk and Nassau County health regulations. From excavation and tank placement to leaching field setup, our experienced team ensures clean, efficient, and environmentally sound results.
Demolition
Steele Contracting offers safe and efficient demolition services for homes, outbuildings, driveways, and commercial structures. We handle permits, debris removal, and recycling with precision — leaving your site ready for new construction or landscaping.

For a low-maintenance, high-impact finish, Steele Contracting installs artificial turf systems for residential yards, athletic fields, and commercial landscapes. Our process includes proper grading, drainage layer installation, and seamless turf finishing for a durable, natural look that lasts through Long Island’s seasons.
