Excavation, grading & driveways in Boulder County
Site grading, building pads, driveways, and utility trenching across Boulder County — the site work that makes a mountain build possible.

Every project in Boulder County starts with moving dirt correctly.
We handle building-pad excavation, site grading, driveways, and utility trenching (water, septic, electrical, communications) around Boulder, Longmont, Nederland. Steep foothill and canyon lots, decomposed granite, and wildfire-interface ground — the exact conditions that eat inexperienced crews.
At 5,200–9,000 ft, freeze-thaw, runoff, and snow load punish anything built wrong. We cut pads and access that hold up, and because we run our own septic and water crews, your trenching and your systems are coordinated by one team instead of three.
What we do
Driveways & access
The difference between a buildable Boulder County parcel and a stuck truck.
Utility trenching
Water, septic, electrical, and communications, dug and backfilled right.
Erosion & drainage
Grading that survives high-country runoff and freeze-thaw.

Excavation, Grading & Driveways in Boulder County — questions
How much does excavation cost in Boulder County?
It depends on volume, access, and ground — rocky, steep, and remote sites cost more per hour. We quote off the actual site conditions.
Can you build a driveway on a steep Boulder County lot?
Yes — steep, rocky mountain access is what we're set up for. We assess grade and drainage first.
Do you trench for septic and utilities too?
Yes, in-house — so your septic, water, and utility runs are coordinated by one crew, not subbed out.
