John's in-depth knowledge of materials, based on 10 years experience in the lumber and building materials business, goes beyond understanding how to select quality support beams, or where to get the best price. We also understand which suppliers have reliable inventories that can be shipped on a moments notice, and where to go to get the right lumber at the right price when there is a shortage. We know what substrate to change to if the soil content of your home site is different than expected, and where we can get it in time to keep the process moving forward.
