Columbia Flooring will institute a price increase of up to 10 percent on its 3/4" prefinished solid oak hardwood flooring products. The increase is in response to a long-running industry trend of rising hardwood lumber costs, according to Columbia.

The new pricing, effective Nov. 1, applies only to Columbia's prefinished oak collection, which includes Adams, Taylor, Carrollton and Thornton 3/4" solid hardwood offerings. The company's engineered hardwood flooring products, exotic Out of Africa Collection and Dales Collection glueless longstrip flooring are exempt from the increase.
