average cost to have hardwood floors installed
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. Custom borders and patterns can look fantastic but bump up installation costs by $1-$2 or more a square foot, adding at least $144-$288 for a 12x12-foot room. 2  The more custom the project, the higher the additional expense.
