Why does wooden flooring makes creaking sound ?

This blog is not going to be very long because the reasons for the creaking sound in wooden flooring have very limited reasons.

1. Uneven sub floor. –

When wooden flooring is installed on an uneven sub floor, the wooden floor makes the creaking sound. The wooden floor have normally  4ft long wood plank. Now suppose there is a depression or bump on the sub floor. As soon as you step on the area where there is depression on floor the planks will press deeper down. Due to this it makes the creaking sound.

If there is bump, here also, all-around the bump there is depression. When you step near the bump area, the wood floor will make the creaking sound.

Now let us get some butter from this.

How to solve this problem ? Mark and identify the area where the creaking sound comes. Remove the wood floor near and around that place. If there is depression fill the depressed area with POP or white cement. If this cannot be done add some extra underlay foam in that area. But harder material will be better. Try to cover the depression. Reinstall the floor. Done.

Now if you find a bump. Get a grinder and grind the bumpy spot and level the floor as much as possible. Reinstall the floor. Done.

This deformed or expanded floor makes the creaking sound.


Remove the floor, create a gap of minimum half inch all around the periphery of the walls and reinstall the floor. Done.
