ᐅ How can I optimize the installation of IKEA Metod cabinets on older walls?

Hello everyone,

I am currently facing the challenge of installing IKEA Metod kitchen cabinets in an older building where the walls are not only uneven but partly made of old masonry with plaster and possibly even multiple layers.

I am especially wondering how to securely and evenly mount the cabinets without the wall anchors or fasteners giving way or coming loose.

Are there specific installation strategies you would recommend, such as certain types of anchors, screw techniques, or tools that are particularly useful for uneven walls and old masonry?

I am also interested in the best way to deal with the unevenness: should I first level the wall, what is practical, or can the cabinets be adjusted so they hang straight even if the wall is not perfectly even?

I look forward to any tips and experiences to help me install the IKEA Metod cabinets as efficiently and securely as possible.

Hello Richard,

I can understand the challenges you face with old walls, especially when using IKEA Metod systems, which are designed for straight lines and standard dimensions. Here are some structured tips for you:

- First: Carefully check the condition of the wall. For old masonry, chemical anchors or heavy-duty anchors are better choices than simple plastic plugs, as they provide better support.
- You can often compensate for unevenness by using custom shims made of wood or plastic on the backs of the cabinets. This helps avoid rigid pressing against the wall.
- If the wall is very uneven, a shadow gap between the cabinet and the wall can improve both appearance and function, so small gaps don’t matter.
- Before installation, you can attach a vertical guide (e.g., a laser level or a straightedge) to align the mounting rails for the cabinets. This ensures a perfectly straight hanging.
- For heavily uneven surfaces, consider mounting on spacers so the cabinet sits about 1–2 cm (0.4–0.8 inches) away from the wall. This way, irregularities can be “hidden” underneath.

Chemical anchors with resin offer strong holding power if the wall is crumbly. Also, do not insert screws straight in parallel; rather, screw them in at a slight angle if it supports the structural stability.

Completely leveling the wall is only worth it if there are significant irregularities or cracks. Usually, it’s faster to work with shims and hang the cabinets on a leveled mounting rail.

Summary: It’s better to use robust fasteners (chemical anchors), precise alignment with laser or spirit level, and adjustment of the cabinets with shims. All this ensures a stable, straight installation despite the old wall.

Hello Richard,

Your question is of great interest to many DIY enthusiasts because older walls often have their challenges. I have personally mounted IKEA Metod cabinets on older walls several times and would like to give you a more detailed explanation:

Before you start the installation, you should check if the wall is load-bearing enough. Old plaster layers can be crumbly, so test this by gently tapping and feeling the surface. Any loose plaster parts must be removed and repaired before mounting.

For anchors, it’s better to use heavy-duty anchors or chemical anchors. These hold better in old masonry than simple plastic anchors. If the wall is very porous, a granular resin injection for reinforcement might be worthwhile, provided you can do this professionally.

I can only confirm that. A tip from me: It’s best to first roughly lay out the entire cabinet row and then mark the heights for the shims. This way, you can adjust everything together before the final mounting.

If the wall is extremely uneven, you can also consider installing a substructure of horizontal wooden battens on which the Metod profiles are mounted. This gives you a flat base even if the wall itself is crooked.

Last but not least: Be patient when aligning and remember to use a level repeatedly. With patience and careful preparation, your kitchen cabinets will hang very stable and straight.

If you have any further questions, feel free to ask—I’m happy to help!

That’s my favorite tip! I agree completely: instead of struggling with frustration and constant adjustments, a substructure creates the perfect base for your Metod kitchen stars.

I did the same in my old building — in the end, it looks like a small wall on which you can easily hang the cabinets. You can even add small spacers to the substructure if the wall bulges in some areas. Just like naujon and Annedeo say, visualizing and adjusting becomes much easier and more relaxed this way.

Just make sure to protect the wood against moisture and pests, since older buildings can sometimes hide surprises behind the wall. A little primer can work wonders here.

And one more practical tip: allow some space for the inevitable screw holes — you’ll need them. It’s better to have one hole too many than to come up short when things don’t align perfectly!

Good luck installing your IKEA Metod kitchen — you’ll manage just fine!
