As a longtime Masonry Wholesale Distributor, WSS has a large offering of Clay, Cement, Paving, FireBrick as well as many accessories to go along with it. Always maintaining that brick was relatively strong, long lasting and easy to maintain when used in construction.Cement and Mortar are the backbone of the masonry business. William S. Simpson Co. Inc. is a distributor for several companies whose chemicals enhance, protect, and beautify. There are cleaners, additives, sealers, caulking and other chemicals used in the masonry/building materials business. Our vendors alongside us strive to supply you with useful and safe chemical products. VOC compliant, OSHA and DOT safety are always paramount concerns. Check out the links to our suppliers sites for MSDS and Tech Spec info and feel free to call WSS for more information. Many of the lines we have carried for years overlap into other segments of the building supply industry. We recently came to the conclusion that if we're servicing lumberyards and stove shops as well as the masonry yards, and the materials are readily available to us...why don't we cross over and sell these items along with the usual fare. Hence we are offering some roofing items, chemicals, vents etc. Why should our customers have to look to others for these things when our trucks are delivering to them anyway.
