Builders FirstSource is a leading U.S. supplier of building materials and building products for builders, contractors, and remodelers, providing trusted products, industry expertise, and support for new construction, remodeling, and home improvement projects. Our Los Angeles, CA lumber yard serves customers throughout Glendale, South Pasadena, Pasadena, Alhambra, Monterey Park and surrounding Southern California Area. We provide framing lumber and other essential building products to support residential construction and remodeling projects. With reliable service, convenient pickup and delivery options, and knowledgeable local expertise, we're proud to be known as builders' first choice.
The main thing I'd say that needs improvement is that there are no prices listed in the lumber warehouse and none of the employees know the prices.
