Our Story
SGW Excavation is a family-owned excavation contractor based in Bow, New Hampshire, serving communities throughout Southern NH, the Seacoast, and the Lakes Region. We represent the fourth and fifth generations of our family in the excavation and construction industry, bringing decades of experience to every project we take on.
SGW Excavation was founded in 2020 by Tristan Noiseux, who began his career working for several large construction companies in the area. Through various positions across different types of projects, Tristan developed a comprehensive understanding of excavation work and what it takes to deliver quality results on time and within budget.
In 2021, Sylvain Noiseux joined the company, bringing 45 years of construction experience to the business. His background spans road building, large-scale site development, utility work, drilling and blasting coordination, estimating, and project management. Together, Tristan and Sylvain combine hands-on excavation expertise with the project management skills needed to handle complex residential and commercial projects.
