A Family Tradition Of Excellence & Service Since 1921


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.
