Can You Run Hardwood Flooring Parallel To Your Joists?

The direction in which your hardwood flooring is laid is generally up to you.

There are some cases where technical specs need to be followed, however in most cases a choice of direction can be made.

In cases where hardwood timber is laid directly onto joists (subfloor structure), then you will have to lay them at right angles for obvious reasons, leaving you with no choice.

So the first thing you’ll need to think about is the direction of your floor joists.

Where plywood is screwed directly to floor joists as a barrier between the hardwood floor boards, in most cases it’s still the conservative option to go perpendicular across the flooring joists.

Over time, this can result in the plywood sagging in between the joists, and if the plywood drops, it could possibly cause your hardwood floor to twist and buckle causing major issues and unpleasant aesthetics.

If your laying floorboards over particle board, or concrete slab with battens or any other type of core solid structure, then you have the option of which direction.

Newer residential homes or those typically built later than 1990, are subjected to more rigorous building regulations. Newer houses have more level sub-floors that are required by code to meet minimum deflection scores.

The directions you lay hardwood floors in a new house is based more on visual and style factors as opposed to the directions of the joists. In these instances the wood floor planks are normally laid in parallel to the longest run or wall in the installation.

It’s always best practice to inspect the sub-floor first to identify the levelness and evenness.

Any sagging or bounce across the sub-floor will be noticeable. Where there are instances of this you’re going to have to either repair the subfloor structure or lay the floorboards perpendicular to achieve greater structural strength.

Try to avoid altering directions in your flooring in various spaces, and do your finest to prepare the layout prior to starting your floor installation.
