Phoenix Foundation Company is a geotechnical contractor based in Douglas, Massachusetts, that drills vertical geothermal boreholes and installs closed-loop ground systems as a specialty subcontractor on commercial and institutional projects across New England. Listed in the IGSHPA directory as a Ground Loop Installer, the company applies deep-foundation and drilling expertise to geothermal bore fields rather than selling residential heat pumps or HVAC equipment. Its documented geothermal work includes drilling a network of twenty-two closed-loop, 800-foot boreholes for the Mary Ellen McCormack public-housing redevelopment in Boston, using air-rotary down-the-hole hammer drilling. The firm's broader geotechnical services cover deep foundations, earth retention, and grouting, with project experience spanning Massachusetts and neighboring New England states. Engagements are business-to-business and institutional in scope rather than direct-to-consumer.
