Expert Excavation Services in Vermont & Upstate New York
Davenport Excavation was founded in 1984 by Doug Davenport, who transitioned from the family farm to establish a trusted earth-moving business rooted in Southern Vermont and Upstate New York. With over 35 years of experience, our family-owned company specializes in residential and commercial site work, including septic system installation, replacement, and repair. Dougs father, George, a seasoned dozer operator with military and conservation program experience, mentored him, laying the foundation for our commitment to quality and reliability. In 2016, Doug passed leadership to his son Ryan, a University of Vermont Civil Engineering graduate, who brings advanced expertise in commercial and industrial site construction, automated machinery, and Vermont-certified water/wastewater system design.

Our team prioritizes strong customer relationships, efficient execution, and quality craftsmanship, ensuring every project aligns with client visions. Ryans certifications, including Vermont Shoreline Act Contractor and Engineer Intern License, underscore our technical proficiency. We supply premium materials like crushed slate, stone, and organic topsoil, supporting diverse projects from driveways to municipal site work. Our portfolio spans septic systems, retaining walls, demolition, and landscaping, reflecting decades of adaptability and trust. Customer satisfaction remains central, with 24-hour response guarantees and seasonal flexibility in operations. This legacy of expertise, family values, and community focus continues to drive our success.
