Larry Gagnon, Gagnon Construction Company - Chelmsford, Ma, has been building additions and remodeling homes for over twenty-five years. During that time, he has developed a strong reputation for producing the very best in value, quality, and service. “For my clients, building an addition or remodeling a house or room, should be a very personal and unique experience, says Larry.” This collaborative process is always aimed at accommodating the aesthetic vision of the homeowner, taking into consideration their practical and functional needs. “In the construction process, I get to know a lot about their needs, including optimizing the flow of their space, and learning what really matters to them. I make sure our custom craftsmanship reflects the values, tastes, and day-to-day activities of my clients. In addition, we aim to deliver in a timely manner and cost contain within their budget.”


Larry and his team have also been providing custom carpentry in distinctive homes and they are more passionate than ever with their craft. “It is very important to give the homeowner the utmost level of detail with each of their interior or exterior projects, says Larry.” The custom carpentry includes all the finishing touches that will enhance each home’s character from coffered ceilings to detailed moldings and mantles to built-in bookcases and stately staircases. Gagnon Construction Company can upgrade any room in any home with custom carpentry!

Sensitive to the benefits of adding increased property value to each project, Larry advises his clients relative to the most efficient solutions for their respective homes. He not only raises the roof of each custom built project but he continually raises the bar of the quality and service he provides each new client, each new home, each new room.
