APR Supply Co., a fourth-generation, family-owned plumbing, HVAC, PVF, and irrigation distributor now in its 104th year of business, announced today that it has officially completed the acquisition of McArdle & Walsh, Inc., a respected supplier of plumbing, heating, and industrial products serving contractors across the Greater Baltimore region for more than a century.

Founded in 1922, McArdle & Walsh has built a strong reputation for deep industry expertise, reliable service, and long-standing customer relationships. The acquisition brings together two legacy organizations that share a commitment to exceptional customer experience, product knowledge, and continued investment in the trades.

“We are excited to officially add our first Maryland location to the APR family,” said Scott Weaver, CEO of APR Supply Co. “McArdle & Walsh’s long-standing dedication to the trades and strong presence in the Baltimore market align perfectly with our values and growth strategy. Together, we will build on both organizations’ strengths to deliver even greater support to professional contractors for generations to come.”

Together, APR Supply Co. and McArdle & Walsh represent more than 200 years of combined service to the plumbing and HVAC industry. APR Supply Co. is focused on ensuring a smooth transition for McArdle & Walsh customers and teammates, while preserving the relationships, expertise, and local identity that have defined McArdle & Walsh for more than a century.
