ᐅ Why do some Billy shelves start squeaking only after being used for a while?

In recent weeks, I’ve noticed that my Billy shelves from IKEA start squeaking only after being used for some time. I don’t mean right after assembly, but rather after a few days or weeks once the shelves have been in use for a while. I am particularly interested in why this happens. Is the squeaking caused by material fatigue, exposure to moisture, or possibly by the fasteners slightly loosening over time? I would also like to know which factors contribute to this noise and whether it can be prevented permanently without completely taking the shelf apart. Maybe there are tips on how to specifically avoid this effect. I’m looking forward to your experiences and explanations!

It’s great that you’re looking into this topic so thoroughly! 🙂 I suspect that with Billy-type shelves, the main issue comes from the combination of wood particle boards and the adjustable shelves. Weight and movement create small friction points between the components. If dust or moisture gets in there, it tends to make the squeaking worse.

Even if the screws and dowels aren’t entirely loose, this slight movement can be enough to cause noise. Sometimes, applying a bit of lubricant or wax to the joints can help prevent the squeaking. It’s really interesting how many small factors can affect such a simple shelf!

The squeaking of Billy shelves after extended use can be technically explained by the properties of the material and the construction.

1. Material expansion: Particle boards respond to changes in temperature and humidity by slightly swelling or shrinking.
2. Friction points: Slight movements at connection points, especially around dowels and screws, cause friction.
3. Settling movements: The weight of the items placed on the shelves can cause components to shift slightly and rub against each other.

To reduce squeaking, the following measures are recommended:
- Tighten all screws and dowels after the first few days of use
- Use dry lubricants (e.g., silicone spray) on contact surfaces
- Avoid high humidity levels in the room

This information is based on building and furniture engineering and should explain the issue in most cases.

Very well observed. I would like to add a brief guide to prevent squeaking:

1. Construction: When assembling, make sure all joints fit tightly; fasten dowels and screws securely, not too tight but firm.
2. Adjustment: After about 1-2 weeks of use, check all fasteners again and tighten if necessary.
3. Lubrication: Applying a thin layer of beeswax or graphite powder on the joints can reduce friction.
4. Environment: A dry, well-ventilated room is ideal. Avoiding moisture keeps the material stable.

Summary: Small movements at contact points usually develop over time, which is why squeaking appears with a delay. Preventive readjustment and lubrication are key to long-term noise-free performance.

Hey, I think it’s great that you’re looking for sustainable solutions right away! 😊 So, yes, you don’t always have to take the entire piece apart. Often, it’s enough to target the problematic areas.

These small squeaking noises usually come from slight movements at the wood-to-wood or wood-to-metal joints. For example, in my Billy shelf, I simply inserted small felt or foam rubber strips* between certain parts. This cushions the friction and effectively reduces the squeaking. And if the screws feel a bit loose, tighten them – but be careful not to overtighten, as that can cause more damage than good.

*Fun fact: This was really easy and a nice DIY approach without complex tools or long disassembly. Plus, it really saves your nerves in the long run – good luck, and no more squeaking! 😉
