Duggan Builders is a design-build firm based in Sagamore Beach/Bourne, MA, run by John Duggan, serving Cape Cod, the Upper Cape and towns south of Plymouth. Houzz lists a Massachusetts construction supervisor license (CS 094530) for the company, attributed to that directory rather than independently verified against the state registry. The one written account on file, a 2020 Houzz review, describes John Duggan completing a full home renovation on a foreclosure purchase in Sagamore Beach. The homeowner called the process effortless despite a complicated project, credited Duggan's experience and knowledge with exceeding expectations while staying within budget, and recommended him as an honest, reliable and professional builder. With only one detailed review on record, anyone considering Duggan Builders for a renovation should ask for references from more recent projects and confirm current licensing directly before booking.
