The procurement director for a Fredericksburg-area building supply company has given up worrying about lumber prices. Thomas Kujawa said that his concern now is actually getting shipments of 2-by-4s, floor joists and other wood products, which have more than tripled in price, from sawmills to Jim Carpenter Co. in Spotsylvania County so he can supply his customers. âThere have been acute shortages for two years,â he said. âLast year, the hot ticket item was pressure-treated wood. This year, everything from floor joists to panels to lumber have been in short supply. When you canât find it, the prices become secondary.â
