Join in with the Joists
More modern homes have a floor joist system and a sub-floor. Experts have always been aware of the effect floor joist direction can have on the performance of solid 3/4 inch hardwood floors. The preference has always been, to install perpendicular to the joists, as it provides stronger support for the floor going over top. Installing along with or parallel to the floor joist system, can lead to sagging or board separation.
