Keystone Maintenance Services Corp

Keystone Maintenance Services Corp is a small disadvantaged, veteran-owned, and service-disabled veteran-owned business headquartered in Sinking Spring, Pennsylvania, that specializes in overhead crane and hoist maintenance, inspection, repair, and installation services for the federal government. The company has been registered in SAM.gov since January 2, 2002, and maintains active certifications as a self-certified small disadvantaged business and subchapter S corporation. With its expertise in specialized equipment maintenance and demonstrated track record across multiple Department of Defense installations, Keystone Maintenance Services Corp has established itself as a key provider of critical infrastructure support services to federal agencies, particularly the U.S. Army and other military facilities throughout the Northeast region and beyond.

Keystone Maintenance Services Corp has secured numerous prime federal contract awards totaling millions of dollars for comprehensive crane and hoist services at various military installations and federal facilities. The company's work encompasses inspection, certification, preventative maintenance, load testing, repair, and installation of overhead cranes with lifting capacities ranging from 300 pounds to 60 tons, as well as sling maintenance services. Primary locations where Keystone has performed work include Letterkenny Army Depot and Letterkenny Munitions Center in Pennsylvania, Fort Drum in New York, Aberdeen Proving Ground in Maryland, Tobyhanna Army Depot in Pennsylvania, Fort Detrick in Maryland, and facilities operated by the National Institute of Standards and Technology. The company has received contract awards from multiple federal agencies including the U.S. Army Materiel Command, Army Contracting Command Redstone Arsenal, Army Installation Management Command Northeast Region, Joint Munitions Command, Army Test and Evaluation Command, National Institute of Standards and Technology, and Communications Electronics Command. Recent significant awards include a $209.75 million firm fixed-price contract for overhead crane hoist replacement at Fort Drum (awarded September 2025), a $210,225 delivery order for crane services at Letterkenny Army Depot (awarded September 2025), and a $113.3 million contract for crane inspections and maintenance at Letterkenny Munitions Center (awarded September 2025). Many of Keystone's contracts have been designated as total small business set-asides, reflecting the government's commitment to supporting small enterprises, though several recent awards have been issued without set-aside designations as delivery orders under existing indefinite delivery contracts.

Keystone Maintenance Services Corp currently holds four active indefinite delivery vehicles that serve as the foundation for its federal contracting activity. The company was awarded a $1,003,380 indefinite delivery contract by Army Contracting Command Redstone Arsenal in September 2024 for inspection, preventative maintenance, and repair services on overhead cranes at Letterkenny Army Depot and Letterkenny Munitions Center, with an ultimate completion date of September 12, 2027. Additionally, Keystone holds two blanket purchase agreements valued at $499,999 each with the Army Installation Management Command Northeast Region—one awarded in April 2025 and another in January 2024—both for overhead crane repair and replacement services at various military facilities through January 2029. The company also maintains a $450,000 blanket purchase agreement with the Army Installation Management Command Northeast Region awarded in July 2022, though this vehicle has an expiration date of October 23, 2023. These IDVs establish Keystone as a standing contractor capable of responding to task orders for crane maintenance and replacement needs across multiple Army installations in the Northeast region and beyond. The vehicles support both firm fixed-price and time-and-materials delivery orders, enabling the Army to efficiently procure critical maintenance services for aging overhead crane infrastructure that is essential to base operations and personnel safety.
