Where it sits among every floor wood.
Hardest first. Floors we carry in oak brown, the rest in tan, red oak in black. How the Janka test works.
The number is a start. The floor is the answer.
Hardness is one fact among many: the finish, the sheen, the width and how the house is lived in all count. A free visit puts one of us in your rooms to weigh them with you.
