Serving the Rogue Valley & Southern Oregon
Pacific Earthworks LLC is a licensed, bonded and insured excavation and construction contractor based in Williams, Oregon, handling everything from custom home site prep and foundations to septic systems, retaining walls, grading and ponds across Southern Oregon.
Southern Oregon's Earthwork Specialists
Before the house, the shop, the driveway or the drain field, the ground has to be right. Pacific Earthworks handles the excavation, grading, foundations and underground work that quietly determines whether a project lasts for decades, or starts settling and cracking in a few years.
We bring the equipment, the operators and the attention to detail to do it once and do it correctly. From a single trench to a full custom-home site, every job gets the same standard: precision, punctuality and performance.

Excavation is unforgiving, small mistakes get buried and become big, expensive problems later. Here's how we make sure that doesn't happen on your project.
Grades, depths and compaction done to spec and verified, never just eyeballed, so everything built on top stays true.
We show up when we say we will and keep your project moving. Your schedule, trades and budget depend on it.
The right equipment, experienced operators and clean execution. High-quality work at competitive prices.
Owner-operated and rooted in Southern Oregon. You deal directly with the people doing the work.
