Deck Building Company in New Hampshire's Seacoast

Serving Families in New Hampshire’s Seacoast Since 2014

Built on Generations of Craftsmanship

Allan Trant’s journey in construction began long before the founding of Allan Trant’s Exterior Finish Work in 2014. As a third-generation carpenter, Allan grew up on job sites, learning the importance of precision, hard work, and doing right by the customer from an early age. His hands-on experience, dating back to childhood projects alongside his father, shaped his philosophy of honest craftsmanship and building spaces that stand the test of time.

Today, Allan leads a skilled team dedicated to delivering high-quality decks and outdoor living spaces throughout the New Hampshire Seacoast. His commitment to doing what’s best for the homeowner—not upselling unnecessary work—has made his company a trusted name in the region. Every project reflects the same care and attention to detail he learned growing up, ensuring homeowners get lasting value and beauty for their investment.
