John Duggan has been in the Real Estate and Construction business for over 20 years. He prides himself on completing your project “On Time” and “On Budget”! With a combination of design and management experience, Duggan Builder’s goal is to exceed our customers expectations.


John worked closely with us right from the beginning – from seeing the land for the first time, purchasing the land, designing our home and all the way through construction. Working with Duggan Builders has been a great experience and we look forward to working with them again on future projects. We would definitely recommend them!

John was present for all aspects of construction and available to answer any questions or concerns. His reliable, experienced subcontractors and relationships with the town made it a smooth and easy process.

To our amazement, Duggan Builders fully rebuilt the house, and it’s site, On Time and On Budget.. While John’s active on-site management ensured smooth coordination of the project.

John exceeded our expectations,we were unaware of how much personal attention he would give us. The entire process, from clearing the land to occupying the home, was exactly as planned. Not only did he save us money, the job was done on time and on budget! We highly recommend Duggan Builders!
