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

Hello everyone,

I am currently planning to install an IKEA Metod kitchen in my older apartment but am facing some challenges, especially regarding the installation of the kitchen cabinets on the mostly uneven walls typical for older buildings. The walls consist partly of old masonry with varying degrees of unevenness, so the mounting rails and cabinet connections often do not fit properly without adjustment.

I am interested in how you optimize the installation in such cases to achieve a stable and level kitchen run. Which tools, aids, or techniques do you recommend for compensating for uneven surfaces and aligning the Metod units neatly against older walls?

Are there any proven methods or special fasteners that you use? And how do you deal with wall rails that are not straight?

Thank you in advance for your tips and experiences!

Hello Pehau,

Your question touches on an important issue that is often underestimated when installing IKEA Metod kitchens in older buildings. Walls in older buildings are usually not only uneven but also often not perfectly vertical or level, which makes installation more difficult and requires adjustments.

My advice is to approach the installation in several steps with care. First, you should definitely use a long spirit level and a laser level to align the mounting rail as precisely as possible. Keep in mind:

- Mark the vertical and horizontal lines on the wall by taking multiple measurements
- Use mounting rails that can be leveled with shims or washers if needed to compensate for unevenness
- Use high-quality wall plugs and screws, appropriate for the wall material (concrete, brick, old plaster)
- Check whether struts or wooden battens need to be installed as a subframe to create an even surface

It can also help to align the floor precisely, as this allows better compensation for wall irregularities. For sloping walls, a custom-made wedge profile is recommended to get the mounting rail straight.

Also, pay attention to the order of installing the base cabinets: install the base cabinets first, then take measurements for wall shelves or wall cabinets, as this allows for more tolerance.

Important: Take your time for preparation. Incorrect alignment can be very difficult to fix later, especially once the cabinet fronts are installed.

If you like, feel free to share more details about the wall thickness and material – that will help provide more targeted advice!

Measure walls and floors precisely using a laser.

Level with spacer strips under the mounting profiles.

Install heavy components first, overlapping them.

Use special anchors for older walls.

Ensure a horizontal level, even if the wall is slanted.

Hello Pehau,

I fully agree with Parbo and would like to add some important points, especially when dealing with old walls. These walls are often not only uneven but also covered with old plaster layers that may be crumbly or porous. This can significantly affect the load capacity of anchors.

A common mistake is to screw the mounting profiles directly to the wall without first checking the wall condition. For this reason, I strongly recommend:

- Before installation, tap the plaster lightly with a small hammer to check if it is solid enough.
- If not, remove any loose plaster and level the anchor points with filler mortar or repair putty.
- Use appropriate heavy-duty anchors depending on the wall structure (e.g., cavity anchors or chemical anchors for porous masonry).
- If needed, use mounting profiles with rails where you can insert adjustment blocks to precisely compensate for unevenness.

Another tip: align and securely fix the cabinets at the floor before mounting the upper units. This helps minimize sagging, especially on old floors that may not be completely level.

Finally, I advise double-checking all measurements and measuring twice before drilling. It’s also helpful to work with a template that you position at several points on the wall in advance.

If possible, having a second person align the formwork while you fasten it makes the process much easier.

I hope this helps!

That is basically correct, but I think it’s also important to critically consider whether the standard Metod profiles are really suitable for all types of old building walls.

That only helps if the substrate can bear enough load – very often you see the plaster is old and crumbly, so even the strongest anchors fail.

Therefore, I recommend thoroughly inspecting the wall beforehand – through small drill holes or with an endoscope if available. If the wall is too deteriorated, it’s better to install a kind of substructure with wooden battens that can be securely fixed.

Only this way can a permanently stable kitchen installation be ensured later on. By the way, Metod is very modular and offers some flexibility, you just have to be willing to improvise and not just blindly nail the system to the wall.

I’m curious to know how others handle this, especially with different wall materials in older buildings? Their experiences would be interesting.
