However, if you have a disability we are here to help you. Please call our disability services phone line at 530.362.2271 during regular business hours and one of our kind and friendly personal shoppers will help you navigate through our website, help conduct advanced searches, help you choose the item you are looking for with the specifications you are seeking, read you the specifications of any item and consult with you about the products themselves. There is no charge for the help of this personal shopper for anyone with a disability. Finally, your personal shopper will explain our Privacy Policy and Terms of Service, and help you place an order if you so desire.

In 1921 Edward J. Pardini Sr. co-founded Hills Flat Lumber Co. as a wholesale lumber mill. Hills Flat Lumber Co. quickly grew to three mills in order to supply the community’s growing needs for lumber. Along with new home construction & Victorian remodeling needs, Hills Flat Lumber Co. also played a major role in supplying lumber for water & irrigation flumes in and around Nevada County. Hills Flat Lumber’s other major consumers were the local gold mines. Hundreds of miles of underground tunnels were braced and shored up in order to protect the miners from the thousands of feet of rock and soil above their heads, and Hills Flat’s quality lumber was trusted to keep the miners safe while mining for gold. In the 1950’s the Hills Flat Lumber Co. mills were sold and Edward J. Pardini Sr. diversified his business to not only lumber, but hardware, building materials and rentals. The Pardini family business philosophy was simple…..provide superior service & the highest quality building materials available.

Since that time three generations of the Pardini family have owned and operated Hills Flat Lumber Co. at its original location. Hills Flat Lumber Co. is dedicated to continuing Edward J. Pardini’s high standards of service & quality to all of our customers…including professional contractors, remodeling contractors and do-it-yourselfers.
