Trumbull-Nelson Construction Company describes its work as general contracting for residential, institutional, commercial and industrial clients throughout New Hampshire and Vermont. The company says it was founded in 1917 and has moved from Hanover to West Lebanon. A 2017 customer said Eli, John and Tom built a 28-by-12 farmer's porch in two and a half weeks, arriving on time each day and finishing ahead of schedule despite snowstorms and foul weather. The 2017 customer said project manager Christian was accessible and the project stayed on budget. A 2022 customer said a commercial building Trumbull-Nelson had built 30 years earlier had held up well, and praised the company's organization and work quality. A 2024 subcontractor said working with Trumbull-Nelson was a pleasure and described management and field personnel as personable and professional.
