Wood flooring is on the top list of most of todays home reno’s … just watch some HGTV episodes. In the past 2″ Oak flooring, as pictured here, was installed in many homes in the early 1900”s.
Due to it’s thin 3/8 inch thickness, it can only be sanded a few times before the tongue and groves that join the strips together rise to the surface …causing the oak to split and crack.
As a result the floor is generally no good and un-repairable.
