In 1891, E.M. Duggan, began as a modest plumbing repair and maintenance business founded by Edward M. Duggan I. Today, a fourth and fifth generation continues the proud tradition of providing top-quality plumbing, HVAC, and fire protection to eastern Massachusetts industries, including commercial, industrial, institutional, medical, government, and multi-family residential.

From the time it was founded, E.M. Duggan has earned a stellar reputation for high quality work and outstanding service. We are known for completing projects on time and within budget, and for controlling cost with our prefabrication capabilities. We thank our clients and are proud to work with some of the biggest and best general contractors in the area.

As competitors have come and gone, E.M. Duggan has endured and diversified. Our policy of planned growth ensures consistent quality throughout expansion. E.M. Duggan has kept up with emerging market technologies like building information models (BIM). From the beginning we have sought to be the best at meeting our clients' needs, reliably providing dedicated service espoused by our founder in 1891.
