Denron Plumbing & HVAC and J. Lawrence Hall merge businesses

Manchester, NH Two of New Hampshire’s most successful mechanical contractors have combined teams to form a commercial plumbing and HVAC powerhouse in the market.

Denron Plumbing & HVAC LLC, serving commercial and industrial plumbing and HVAC clients throughout New England since 1974 and J. Lawrence Hall, family-owned and operated design-build mechanical contractor in Nashua since 1937 have merged.

The merged companies will be known as Denron Hall Plumbing & HVAC

“It was important for us to find a partner who could help carry on the legacy that of our family built over 8 decades,” said J. Lawrence Hall president Charlie Hall. “Taking care of our employees and customers long term have been our top priorities and the merger with Denron accomplishes both.”

The merged company will maintain both their Manchester and Nashua locations and will have more than 200 employees. Although both companies previously provided both plumbing and HVAC services to general contractors, building owners and facility managers throughout northern and central New England, Denron’s strength was on the plumbing side and J. Lawrence Hall had a strong background in HVAC, including their own sheet metal shop.

“It truly is a merger of equals, with each of the companies bringing unique specialties to the table,” said Denron Hall CEO Joel Pickering “Bringing together these two great companies makes us stronger in the marketplace.”

“There’s no one in the region now that brings this level of expertise in plumbing, HVAC construction and building services at this size and scope to a project,” said Pickering. “Additionally, by maintaining the two locations allows us to better serve our service and maintenance customers in southern New Hampshire and northern Massachusetts.”
