What Our Customers Say
Real, verified reviews from Southern Oregon property owners, builders and business owners who trusted Pacific Earthworks with their site work.
We recently hired Pacific EarthWorks for excavation and cleanup at our new Apple Outlaw Taproom in Jacksonville, and they did an outstanding job. From start to finish, their team was professional, efficient, and thorough. They tackled the site prep with precision… Highly recommend them for any earth-moving project!
We went through a proposal process for maintenance and repair of our long driveway where we had four reputable companies submit proposals… But one really stood out and that was Pacific Earthworks. The outcome exceeded our expectations. He told us how long it would take and he was spot on. Pacific Earthworks gets our highest recommendation.
Jared, Patrick and Jeremiah at Pacific Earthworks are top notch… They spent about 2 weeks on my 40 acres and did above and beyond my expectations. Even after our first rain, no puddles, no potholes, and all the water stayed in the gutters where it's supposed to. They stayed within budget and did not try to nickel and dime for more pay.
