About Us

From 1954-1956 my father (a Canadian immigrant) worked for a local commercial construction company. At the time, he was building many of the schools and churches in the Southern NH area. In 1956 he and my mom Rita started their own company called Laurier Theriault General Contracting. After many successful years serving the community building homes, additions as well as site work and paving, my parents decided to retire in 1980. This is where I com in. I graduated from Nashua in 1975. I attended Berklee College of Music in 1976. I left college to work in the family business full time. I took over the business and as a tribute to my family, changed the name to Theriault and Sons, Inc., which was incorporated in 1980. Our main focus has been residential paving and general excavating services. Over the years I have attended several night classes at various universities such as Wentworth Institute of Technology, Northeastern University and UMass Lowell, which have helped me to stay current with today’s technologies.

My wife Suzanne and I also have the pleasure of raising our two children in this community and continuing the family tradition. Sam has always had an interest in the business. He graduated from Souhegan High School in 2012 and is no working full time for Theriault and Sons, Inc. He is also studying at Wentworth Institute of Technology in the Construction Technology Program. We have enjoyed helping homeowners and businesses with their paving and miscellaneous excavation needs. We are staffed with an n exceptional, experienced crew dedicated to serving our customers with reliable, quality service, and with state of the art equipment. We are fully insured and will be happy to secure a permit for your job, if necessary.

I am pleased that you are considering Theriault & Sons, Inc. for your paving or excavation needs. My name is David Theriault. Sam and I look forward to serving you.
