Landscape Materials
in Covina


O.F. Wolfinbarger has been serving the Upland, California region as a trusted supplier of landscaping products for the better part of a century now. With a lengthy and storied history in landscaping products and building products, we've built a strong foundation of excellence and are pleased of the reputation we sustain in the area.

When a company has enjoyed success for over 90 years, there's likely a effective reason for it. At O.F. Wolfinbarger, our success story started off four generations ago when our patriarch Olin borrowed $350 from the bank to buy a truck for hauling cow paddocks. What started off as an casual business transaction between a farmer and a dairyman has since developed into one of the leading providers of landscaping materials in the Southern California area. At the heart of our business is our custom soil mixing. This service was born out of necessity when neighborhoods began moving into the once-barren foothills of the area.

Why Choose O.F. Wolfinbarger Inc. As Your Dependable supplier of Landscape Materials? We're popular among homeowners, businesses, and building products companies throughout the region. We would love to add you to our lengthy list of satisfied clients. Find out for yourself why we are the go-to place for landscaping in the area.

5 star ratingJust had a great experience at Wolfenbarger.  Needed a specific kind of landscape rock (pyrite), and was not able to find it at other material centers.  Wolfenbarger has a large selection of rock, including pyrite.  Price was right too.  Thank you!

4 star ratingWe have done business with them a couple of times now for 2 different properties, and have had no issues. First time we picked up a few scoops ourselves, and the second time we had it delivered. The delivery was smooth and they even called in advance to let us know driver was on his was. This company has good prices, and I would do business with them again. The ladies in the office can be a bit more friendly since they are dealing with customers (only reason I didn't give them 5 stars)
