Harbour Group has acquired Symmons Industries Inc. and Symmons Connected LLC, bringing a longtime commercial plumbing manufacturer and a smart water management technology business into its industrial and building products portfolio.
Financial terms were not disclosed.
Founded in 1939 and based in Braintree, Massachusetts, Symmons makes specification-grade plumbing products for commercial and institutional markets. Its lineup includes shower systems, faucets, valves, accessories, and replacement parts. Through Symmons Connected, the company also offers intelligent building technology through its Evolution AI-First platform for smart water management in commercial facilities.
The deal expands Harbour Group’s position in building products and flow control and adds a company with both traditional plumbing products and connected water management offerings. The original announcement said commercial property owners are increasingly investing in water conservation, operational efficiency, and predictive maintenance, helping drive growth in digital water management platforms.
Symmons will continue to be led by Chief Executive Officer Tim O’Keeffe, a third-generation member of the founding family.
"Harbour Group has demonstrated repeated success in the flow control and building products sectors", O’Keeffe said. "We believe that their operational expertise and ability to drive complementary acquisitions will enable us to accelerate our strategic growth plans. It was exceptionally important to me and my family to select the best partner to create opportunities for our people and enhance our brand and family’s legacy, and we’re confident we have found that with Harbour Group."
Harbour Group said it plans to support Symmons’ product development efforts while using its operational experience and acquisition background to help drive growth. Jeff Fox, chairman and chief executive officer of Harbour Group, had this to say of the new partnership:
"The O’Keeffe family and Symmons team have built an outstanding business. We are humbled that Tim and his family have partnered with us for the next phase of the company’s growth. Symmons has several new product launches and growth initiatives under way. Those programs, combined with its strong foundation, great people, and our support will create exciting opportunities for the employees and customers of Symmons."
The transaction also reflects continued consolidation in the building products industry, where manufacturers are broadening portfolios and investing in technologies aimed at improving building performance and resource efficiency.
For Harbour Group, the acquisition adds another industrial business to a portfolio that spans manufacturing and distribution across multiple sectors. Since its founding in 1976, the St. Louis-based investment firm has acquired 236 companies in 51 industries, with a focus on operational improvements and long-term growth.
