OTTAWA -- The cost of lumber has skyrocketed during the pandemic. Whether it's building a backyard deck or fence, or framing interior walls for an addition or renovation, the cost will likely be double what it was last year. Initially, Roger Liddle planned for a huge 25-by-30-foot wooden deck in the backyard of his new home in Manotick Ont. Once the design was complete, Liddle priced it out. "The prices we looked at for the lumber last summer was quite reasonable," says Liddle. "If we had just bought the lumber and done the work ourselves the deck would have cost about $3,000 for the lumber itself."
