Retaining Wall Contractors in Newberg, OR

"small glitch in scheduling, but contractor came through full-on onc"

"Accurate bid, quality work, they had some design improvement ideas for me, and friendly and easy to work with. I have had neighbors already hire this company based on the work they have done fror me. I will use them again for a backyard project this spring."

"We hired Jose last summer (2025) to remove some flag stones in the back yard and move them to the front walkway as well as put in a 16x14' concrete slab in the back yard. We interviewed 4 other contractors but he was the only one that gave us ideas on how to make it better than I could have imagined! What originally started as a single concrete slab in the back yard turned into a show piece walkway in the front yard and a back yard patio that was nice enough to add a gazebo! You would think that with all the extra add ons it would have been way over budget but it ended up costing much less than all the other quotes! We are looking at having Jose put in a new 28'x28' slab in the other side of the yard for a possible basketball hoop or, gosh, anything. I really recommend this company. Jose is very personable, professional, and very very qualified. Thanks Again Jose!"
