Hello everyone,
A few months ago, I bought an IKEA Kallax shelving unit and stored it on my balcony during the warmer months. Now that the weather has become cooler and more humid outside, I’ve noticed that the unit has become noticeably more wobbly – its stability has decreased, even though I reassembled it indoors. My question: Are there ways to restore the stability of a Kallax shelving unit after extended outdoor storage? Is it possible to tighten screws, treat the wooden parts, or take other measures to regain the original strength? I would appreciate any expert advice and tips on how to make the shelf stable again without having to replace it entirely.

Structural weaknesses usually occur at the joints where dowels and screws loosen from the glued wood-based panels or where the wood has swollen internally.Thank you for the detailed advice, Filippo. That exactly describes the issue with my shelf – the screws are loose, and as you said, I suspect that the panels have swelled and essentially detached from the dowels. I didn’t want to start fiddling with everything without guidance, but your input is very helpful.
Do I understand correctly that carefully redrilling and inserting new dowels can be a good solution? That should at least make the shelf more stable again? Or is the glue bond between the panels usually so strong that this is not recommended? Are there any practical experiences you have had with IKEA furniture in this regard?

Do I understand correctly that careful re-drilling and inserting new plugs can be advisable?Yes, that is correct. Furniture made from particleboard is very sensitive to moisture. After a certain drying period, gaps often appear where plugs no longer hold properly. Careful re-drilling to create new plug holes in undamaged wood can significantly improve stability. Be sure to match the drill bit size closely to the plug diameter— for example, 6 mm (0.24 inches) plugs require a 6 mm (0.24 inches) drill bit. Screws should also be tightened to the recommended torque to avoid damaging the material.
These steps are a common repair method that regularly works well for IKEA furniture. A complete replacement of the panels is rarely necessary unless there is rot or severe mechanical damage.
Additionally, I would like to point out that moisture damage in particleboard can generally cause internal damage, leading to a loss of compression density and therefore mechanical strength. For this reason, outdoor storage should be avoided whenever possible.
For the repair: If the wood does not show any visible dents or breaks and only the joint is loose, the method of re-drilling and inserting new dowels works surprisingly well.
If you intend to use the shelf permanently indoors again, stabilizing it with metal brackets helps, as this introduces additional support forces into the structure instead of relying solely on the particleboard.
