Watsco has announced that it has completed the previously announced acquisition of The Granite Group, a diversified distributor of plumbing and HVAC products with approximately $500 million in sales throughout seven Northeast States. Watsco’s ownership culture, scale, OEM relationships and industry-leading technologies are now available to Granite’s leadership team and customers to help them accelerate beyond their impressive track record of growth.
Founded in 1971 and headquartered in Concord, New Hampshire, The Granite Group is a third-generation, family-led distributor serving customers across seven states in New Hampshire, Vermont, Maine, Massachusetts, Connecticut, Rhode Island and New York.
The Granite Group serves approximately 11,000 customers from 82 locations and offers approximately 29,000 SKUs sourced from over 450 vendors. The Granite Group has achieved a 10% annual compounded growth rate in sales since 2010 through a combination of bolt-on acquisitions and more than 30 new store openings to win new customers and better serve existing customers.
Watsco’s partnership with The Granite Group adds scale, density, product diversification and deepens its market position in the growing plumbing space – a large and fragmented market that represents compelling avenues for expansion.
The Granite Group will operate as an independent business and will continue to be led by its existing management team, under the leadership of Bill Condron, in keeping with Watsco’s long-standing and successful strategy of investing in great leadership teams and successful cultures.
Albert H. Nahmad, Watsco’s Chairman and CEO said: “The Granite Group is a legendary distributor in our industry with an entrepreneurial spirit that mirrors our own. They have embraced our ownership culture and we look forward to supporting their growth plan with our scale, capital and technology to build on their track record of success. We are pleased to become part of their family.”
Bill Condron, CEO of The Granite Group, commented: “The Granite Group and Watsco share similar cultures and think about the business in similar ways. We love the fact that The Granite Group will remain independent while gaining access to Watsco’s scale, capital, and the most advanced technology platforms in the industry. Our team is motivated to join and collaborate with Watsco’s community of great companies and leadership teams.”
Watsco’s Buy and Build Growth Strategy
The closing of The Granite Group acquisition marks the second, large acquisition completed by Watsco during 2026. In June, Watsco closed on the acquisition of Jackson Supply Company, a market-leading HVAC distributor with annualized sales of approximately $230 million across 25 Sunbelt locations. Jackson Supply offers a balanced product offering of HVAC equipment, parts and supplies. As importantly, Jackson Supply added to Watsco’s entrepreneurial community of leaders.
Watsco has acquired 74 businesses in the HVAC and plumbing markets since 1989, most of which were successful, multi-generation, family-owned businesses. Watsco’s buy and build strategy is as follows:
- Identify and partner with great distribution businesses.
- Support their leadership team and honor the culture and legacies they created.
- Ask for aggressive growth plans and help leadership achieve their ambitions.
- Motivate teams and build an ownership culture with long-term equity.
- Deploy the industry’s most comprehensive suite of customer-focused technologies.
- Solicit and collaborate on big ideas to foster a spirit of innovation and growth.
- Build a stronger Watsco because of our association with these companies.
Watsco is actively seeking additional opportunities to invest and grow through acquisitions to expand its relatively low market share of the estimated $74 billion North American distribution marketplace.
