New Enterprise Stone & Lime Co., Inc. is a family‑owned building materials supplier and highway contractor based in New Enterprise, Pennsylvania. Founded in 1924 by J. S. Detwiler and his son, the company began with quarries and asphalt and ready‑mix plants and later broadened into precast and prestressed concrete, concrete pipe facilities, and additional quarries. Over the decades it expanded its operations through acquisitions, growing its geographic reach with entities such as Martin Limestone, Valley Quarries, Buffalo Crushed Stone, Lancaster Stone, and the Stabler Companies, while leadership remains with multiple generations of the Detwiler family; the firm has also been recognized as a top workplace by the Pennsylvania Department of Community and Economic Development. The company serves construction projects as both a materials supplier and a highway contractor, supported by a broad network of production facilities. A notable recent development is the 2026 acquisition of Frank Casilio and Sons, Inc., which added three ready-mixed concrete plants in Allentown, Bethlehem, and Nazareth to NESL's footprint. The business has demonstrated involvement in municipal contracts, such as street resurfacing work awarded by Hampden Township, illustrating its activity in public-sector projects.
