TG Gallagher is a New England mechanical contractor headquartered in Waltham. The company says it was founded in 1940 and provides HVAC, plumbing, fire protection, and service and maintenance for commercial facilities. Its website describes work for healthcare, higher education, and life-science institutions, alongside a large prefabrication operation. Trade coverage has documented the company’s work and growth over time. ENR reported in 2017 that its Cambridge-based crews had logged about 325,000 worker-hours annually over the prior four years, and local trade groups have described its prefabrication work and industry partnerships. The BBB profile lists an A+ grade and 79 years in business, while noting that the company is not accredited. BuildZoom lists a Massachusetts Pipefitter Master License, MA11196P, and 247 permitted projects, but its contractor profile uses a Cambridge address and says the license was not re-verified after January 2010. Confirm the current license status and which address applies to that profile before relying on those details.
