The floor creaks in the apartment. What to do?

What to do when old wood floor creaks? Of course, renovate! This time we do it, perhaps, in the simplest way.

Before the linoleum flooring had to be cleaned the creak of an old floorboard in only one part of the room. The situation was slightly complicated by the fact that the floor the top is covered with fiberboard, which means it was not possible to look at the boards and find the position of the bearing lags by the hammered nails. In the cracks near the walls, where the plinths were, the logs were also not visible, since the gap is very, very small that you cannot push through a ruler. I had to look for lags by a random method - I twisted it with a screw until I hit it.

To strengthen the floors I decided to use black wood screws 76 mm long. They are equal to about two thicknesses of the board, which is exactly what is needed in such cases. It is also important that there is no thread at the top of such a self-tapping screw.

Thanks to this, it is easy to understand that the self-tapping screw fell into the void, passing through the board, and even when screwed to the end, it does not fold and does not break in half close to the head. This often happens if you use, for example,

55 screws for wood, which have a threadalmost the entire height. Although they are shorter by 2 cm, out of ten pieces I usually have 2-3, when fully screwed into a dense tree, fold.

After the "scientific" research, I found out that the distance between the lags is somewhere around 50-55 cm. In some places, the logs are spliced ​​in the middle of the room, which also needs to be taken into account. This means that you need to find the end of the lag and understand on which side the extended part is located, in order to then continue to twist into it (photo 3) .

Since the ends of the boards stick out from under the fiberboard near the wall, it is not difficult to get into the center of the board with self-tapping screws. In the most creaky places, I screw 2 screws onto the board on each lag. Thus, you can scroll the boards throughout the room, or only locally, as I did in this room.

It turns out to completely remove the squeak in most cases. If the reason for the skip is not in the boards, but in the lags, then it is worth using other methods, for example, long anchors, which should rest against the bottom of the floor slab, and on top should be flush with the board. But that's a different story.
