Got questions about prepping land in Hartsel, installing septic systems, or building a mountain driveway? We’ve been doing this for over 20 years—and we’ve heard it all. Here are answers to the most common questions we get from Park County landowners and homebuilders.
Yes. Septic systems require permits, including soil testing and system design approvals. Excavation for foundations or driveways may require permits if it involves road access, water crossings, or substantial grading. We’ll help guide you through what’s needed.
On average, 2–5 days depending on site conditions, permitting, and inspections. We work fast—but never cut corners.
We coordinate with local engineers and soil testers to get this done properly before installation. It's the first step in designing your system.
We prep sites for cabins, homes, garages, and modular structures. Everything from full foundation dig-outs to crawlspaces and pads, we handle it all.
Absolutely! We live where we work. We specialize in tough mountain terrain. We'll walk your property and design a driveway layout built to handle snow, runoff, and rugged conditions year-round. If your land is especially rocky, keep in mind that rock breaking or blasting may be necessary and should be factored into your budget.
Yes. Proper water management is key out here. We install culverts and grade land to help prevent erosion or flooding around structures and roads.
We’re based in Hartsel and do most of our work in Ranch of the Rockies—but we tackle jobs all over Park County when the fit is right. Not sure if you're in our range? Give us a ring anyway. If you're in the mountains and need dirt moved, we probably speak the same language.
You can, but we’ll probably just call you. We’re old school. Pick up the phone and let’s talk through your project. That’s the fastest way to get real answers.
We handle all the prep work for concrete including grading, trenching, and compacting, but we don’t do the actual pouring. We’re happy to coordinate with your concrete crew or recommend a local pro we trust.
It depends on the season and scope of your project. Smaller jobs can usually be scheduled faster. Call early if you’re planning a spring or summer build. Our schedule fills up fast once the ground thaws.
