We work closely with each client to fully realize their vision, ensuring their involvement in every step of the process.
Leveraging a diverse fleet of heavy equipment — dozers, masticators, and dump trucks — we deliver efficient, timely solutions for site preparation, land clearing, wildfire mitigation, road building, hauling, and septic excavation across Santa Clara County, Santa Cruz County, and beyond. We specialize in the steep slopes, limited-access sites, and difficult terrain of the Santa Cruz Mountains that most contractors turn down. Through long-standing relationships with trusted local suppliers, we keep material costs competitive and projects on schedule.

GM, Automatic Gate Installations & Homeowner · Santa Cruz Mountains
Chris Stille is not only a fearless dozer operator, taking on nasty slopes for a leach field that few others would tackle, but when you call him, he’s there, for however long it takes, no excuses. Cheerful, helpful, and personable… yet really focused when he is moving dirt, paving, or taking down a tree.
George Green
Landowner, Los Gatos, CA
Chris Stille is one of the best contractors I have ever had the pleasure of working with. I have used him for demolition, hauling, road building, installing two septic systems, and the excavation and drainage for my new home. His work is excellent, he delivers timely and on budget, and his pricing is fair. I highly recommend him.
