The price of lumber has skyrocketed since the start of the COVID-19 pandemic. 350% increase from this time last year, said Mike Viozzi, the general manager of Lezzer Lumber in Lancaster.Viozzi said the supply is choked from the forests to the mills, while demand is record-setting.Products like OSB, which is used for roof and wall sheeting, are hard to come by. We can t get it fast enough. It’s almost a little concerning. People don t even care anymore what it costs. They just kind of get it, he said.Before the pandemic, a 2x4 cost about $2.60. Now, it’s $7 or $8.Lisa Cooper, who owns Cooper Custom Homes, said the higher prices are affecting scheduling and the cost of projects. I would say that the cost to build a house has probably risen about 25% in the last six months, she said.Viozzi’s advice is to wait if you don’t have to build right now. The prices will probably come down at some point.
