Builderz Warehouse began in 2016 when it’s owner Ron Wittenberg, was looking for ways to save money on his home renovations. Like many of his peers, he was purchasing building products for the big box stores. Even with his pro discount he knew he could do better. Ron used his contacts to reach out overseas manufacturers and negotiated factory direct container buys on exceptional products routinely used in his renovations. He believed that his fellow real estate investors would also appreciate massive savings on their building products. Fortunately, it worked spread quickly about a local company selling building products at 30 to 70% less than the competition. In less than 30 days he was sold out of his initial order. When a purchasing agent for a large renovation company called and ordered a large order of toilets for a current multi family renovation project, Ron saw the new direction he wanted to take his company. From offering a few products for home renovations he would offer complete turnkey packages specifically for the multi family industry.
Today BW Pro is one of the leading specialty building products companies focusing on the multi family industry. Our new state of the art warehouse can fulfill complete interior material packages from 1 to 100 units and ship in a little as 24 hours.
Originally from the Seattle area, Mr. Wittenberg now resides in Paradise Valley, Arizona with his two English Goldens, Max and Chloe.
