Squeaky and creaky floorboards: How to fix noisy floors

Many homeowners and tenants know the problem: creaking floorboards. Not only is the squeaking of the floor covering annoying, it can also quickly result in a safety risk. This is why you should tackle the problem and fix the planks.

Repair creaking floorboards yourself

Before you start repairing creaky planks, you should first take a close look at the planks: Often it is small cracks or breaks in individual planks that lead to springs and thus squeak. Unless entire floorboards are cracked or, in the worst case, broken, the annoying noise can be eliminated with screws or nails.

If you decide on the variant with the nails, you should make sure to use two nails per board on each beam. These are knocked into the wood at an angle, offset from one another. This means that the movements of the floorboards do not easily loosen the nails. A creaking board can be screwed using a similar principle: Together with a drive-in sleeve, the screw ensures a firm hold and fixes the board in place. Thanks to the special principle, the screws can also be readjusted again, unlike nails.

A structure against the squeak

If the squeaking cannot be remedied by the fixation, we recommend building it under the floor: By leveling the floor in this way, the planks above can no longer bounce; a squeak becomes almost impossible. Chipboard, which is available with and without a cushioning styrofoam layer, is particularly suitable for such a construction. Styrofoam has the advantage that the material not only has an insulating effect, but also cushions steps. This method is particularly good at repairing creaky floorboards on the ground floor or in the basement.

Depending on how uneven your floor is, the use of special impact sound underlay can be worthwhile. These are more flexible than styrofoam and so adapt to the floor. Often this compensation of the unevenness is enough to prevent creaking floorboards from moving. In the case of large unevenness, you should also seal cavities with a leveling compound.

Dry screed as a last resort

If even one edition is not sufficient to permanently repair the floor, only an extremely expensive and equally complicated method can be considered. Planks only lie really quietly on an embankment made of dry materials and a layer of screed on top. However, this method is more expensive than other options and requires a certain amount of manual skill.
