Acquisition of Stancills will expand P. Flanigan & Son’s current storm water management offering and strengthen its environmental approach to infrastructure construction


P. Flanigan & Sons, one of Baltimore’s oldest family-owned construction and transportation infrastructure companies, announced today it has acquired Stancills, Inc., an 83 year-old, family-owned and operated specialty aggregate company based in Perryville, MD. Stancills is a pioneer in the manufacturing of green roof media. Stancills will continue to operate as an independent entity within the P. Flanigan & Sons portfolio, and maintain its current organization and staff.


The acquisition will further enhance P. Flanigan & Sons’ approach to its environmentally beneficial products and business practices by manufacturing in-house the environmental soils they have historically outsourced, ultimately creating efficiencies and reducing costs for their customers.


“Adding to our current concrete and asphalt recycling operations and our recycled and beneficial reuse materials has been a long-term goal of mine,” said Pierce Flanigan, president of P. Flanigan & Sons.


For over a decade, Stancills has been P. Flanigan & Sons’ top supplier for specialized aggregates and custom soil blends which are routinely used by the company in its large-scale projects, primarily in storm water management, sport surfaces and equestrian fields. Aligning their existing synergies will create opportunities for the companies to benefit from shared industry experience and knowledge, intellectual property, and collaboration on further innovations in the manufacturing process and products, not only for building and transportation infrastructure but also in the green building, sports, environmental remediation and defense contracting spaces.


“Stancills has been one of our closest partners for many years and their customized soil products and processes are truly best-in-class,” said Flanigan. “Bringing our assets together under one umbrella will allow both companies to better serve our customers across Maryland and throughout the Mid-Atlantic.”


“Joining P. Flanigan & Sons seemed like a natural step for Stancills, Inc. not only from a business and operational standpoint but also because our companies share the same values,” said Terry Stancill, president of Stancills, Inc. “We are both family-owned businesses proudly founded in Maryland that are dedicated to improving the community and protecting the environment.”
