I have purchased materials at both Home Depot and Lowe's and really have no preference. However, I have found that the workers at Lowe's on Bouquet Canyon are quite knowledgable and helpful. I usually send my clients to the Home Depot on Newhall Ranch Road because it is larger and cleaner. When I am working for women they tend to prefer Home Depot so I go wherever they prefer, as it is their choice. It is a good idea to compare prices. Usually both stores will honor the sale price of the other, if you speak with the manager or someone up front. I like to save my clients as much money as possible. Newhall Hardware Store on San Fernando Road also has many good items.
