Excavation & Septic Services You Can Count On in VT & NY

When you're tackling a major property project—whether it’s a new build, a septic upgrade, or clearing land for future development—it’s not enough to hire just anyone. You need professionals who know the land, the regulations, and the work. That’s where John trombley construction comes in. With roots going back to 1976 and nearly 50 years of continuous service, our team delivers reliable, practical sitework and septic services throughout Vermont and parts of upstate New York.

Septic Services Backed by Generations of Know-How

A well-functioning septic system is one of the most critical components of any property, especially in rural and semi-rural areas like Castleton, Rutland, Addison, and Poultney. At John trombley construction, we offer everything from septic system design to installation, pumping, tank replacement, and even state-approved septic sand. If your system needs maintenance or a complete overhaul, we’re ready.

We don’t cut corners. Our designs follow strict state guidelines while being tailored to your property’s unique soil, layout, and usage needs. Our team takes pride in making systems that last for decades, not just years. And when it’s time for routine pumping or a tank upgrade, we respond fast and get it done right.

Excavation & Sitework Built on Experience

You can’t build anything solid without starting from the ground up. Whether you're clearing a new lot, removing old stumps, grading a driveway, or digging a pond, we offer full-service excavation to set your land up for long-term success. We’ve seen it all—clay-heavy soil, steep grades, soggy lowlands—and we bring the right equipment and crew to tackle the job the first time.

Our services include ditching, drainage, demolition, road grading, pond installation, and more. Vermont’s terrain can be a challenge, but with over four decades of experience, we know how to move the earth efficiently and safely. Our goal? A clean, stable, and build-ready site—without the delays or mess.

Construction & Landscaping Services That Pull It All Together

Once the ground is prepped and your septic system is in place, we’re ready to help you finish the job with strong construction and outdoor improvements. We build retaining walls that protect against erosion, offer roofing services for both repairs and new construction, and handle additions to make your space more livable.

Our landscaping and material supply services make it easy to complete your outdoor vision. Whether you need gravel for a driveway, topsoil for planting, screen gravel for a foundation, or crushed slate for a decorative touch, we’ve got it—and we’ll deliver. We also supply fill dirt and sand to level uneven terrain and prepare for planting, paving, or structural support.
