1 Installing a standard solid-strip hardwood floor averages about $8 a square foot for materials, insulation and site finishing, and up to $12 a square foot for wide pine planks, or $1,150-$1,750 for a 12x12-foot room.
(250 square foot living room) Cost to install hardwood flooring varies greatly by region (and even by zipcode). Get free estimates from flooring contractors in your city. The average cost of installing 250 sq.ft. of hardwood flooring is $2,300.
