Excavation & Sitework.
Every build that lasts starts below the finish line — the dig, the grade, the drainage, the concrete no one photographs. We handle the ground your project stands on, so the beautiful part has something honest to sit on.

What “Sitework” Actually Covers
Most contractors hand you a project and leave the dirt to someone else. We don’t. When an addition needs a new foundation, when an ADU needs a pad, when a basement floods every spring because the grade runs the wrong way — that’s sitework, and it belongs inside the same team that draws the plans and hangs the trim.
Site Prep & Clearing
Clearing, stripping, stump and debris removal, and staging a working site — the first honest look at what's under the surface.
Excavation & Grading
Precise cut-and-fill, land leveling and finish grading so pads, slabs and additions sit exactly where the plans put them.
Foundation & Footing Excavation
Digging to spec for additions, ADUs and new foundations — the difference between a level home and a callback in five years.
Structural Concrete & Flatwork
Footings, stem walls, slabs, driveways and approaches — a stable, square base to start building on.
Stormwater & Drainage
Stormwater systems, footing drains and grading-to-daylight that move water away from the structure instead of into it.
Utilities & Right-of-Way
Underground utility trenching and right-of-way work, coordinated with locates so nothing gets hit that shouldn’t.
Demolition
Selective and full demolition to clear the way for what’s replacing it, hauled out clean.
Land Clearing & Access
Opening up lots, driveways and building envelopes on wooded or sloped Northwest sites.
Retaining Walls & Erosion Control
Hillside stabilization, boulder walls and drainage solutions that keep your site from moving after we leave.
