Comprehensive Building Materials Lists. Whether you are a Builder/Contractor, Lumberyard Salesperson, Architect or Designer, or just building your own private residence; My Materials Lists can help you through the bidding and quoting stages. Use only one list from me; to give to all of your suppliers, so you can compare more easily. I always send my customers' 2 lists; one in an Excel format, and the other in a .pdf file format, for easy manipulation and forwarding purposes.
