ᐅ What tips are there for installing Ikea Metod kitchen units in older buildings?

Hello everyone, I am currently planning the installation of Ikea Metod kitchen cabinets in an older apartment with uneven walls and floors. My question is: What tips and tricks do you have specifically for installing and assembling Metod units in older buildings, to ensure the cabinets stand firmly and do not warp or jam over time? I am especially interested in techniques for dealing with often slanted walls, options for adjusting the cabinet boxes, and the installation of baseboards/toe kicks. Any advice on fastening methods, special tools, or useful aids would also be greatly appreciated. I want to gather practical experience since I have heard that Metod is generally designed for straight surfaces. Thanks in advance!

Hello Bukife, your topic is very important because old buildings and Ikea Metod cabinets are indeed a combination that requires careful attention. For the sloped walls, I recommend assembling the metal frames and carcasses completely without doors first and checking all corners with a spirit level and a square. If the walls are uneven, you can slightly adjust the carcasses or fine-tune them with wooden shims. It is crucial to align the substructure very carefully before screwing the modules together. For baseboards, I suggest using flexible rubber pads or OSB boards as a base to compensate for unevenness. For fastening to old masonry, special anchors such as heavy-duty anchors or cavity anchors are suitable, depending on the wall material. Additionally, a drilling template helps to place holes precisely in uneven areas. In general, take your time when measuring and keep testing the alignment repeatedly during the assembly.

I can provide some very detailed advice on this topic, as I recently installed a Metod kitchen in an older building with walls and floors that were extremely uneven. First of all: walls in older buildings are often far from perfectly square, which makes it difficult to assess with traditional spirit levels and carpenter’s squares alone. I recommend additionally using a digital level (a so-called digital inclinometer app or tool) that can measure even small angular deviations precisely.

- Start by carefully measuring all wall angles and floor irregularities. It’s best to create a simple sketch showing exactly where the deviations occur.
- For the cabinet carcasses themselves, I use flexible mounting aids, which are sometimes available directly from Ikea, such as adjustable feet that can be placed between the cabinet base and the floor to compensate for height differences.
- Important: Do not screw the cabinets directly to uneven walls; always install a substructure made of approximately 18 mm (3/4 inch) thick plywood or OSB boards of the appropriate thickness. This substructure can be leveled accurately and serves as a straight base for the modules.
- You can additionally support the baseboards with construction adhesive if the floor is very uneven. Nothing should wobble under any circumstances.
- When tightening screws, avoid over-tightening if you still need to make adjustments afterwards.
- Also, pay attention to whether your older walls are composed of structural framing, plaster, and possibly textured wallpaper, as this significantly affects the choice of anchors.

One more question: Do you also have floor irregularities in your apartment, or are the issues mainly with wall curvature? This would be important for planning the substructure as well.

Good question, thanks! In fact, besides the significantly uneven walls, the floor is also not level—there are small waves up to 15 millimeters (0.6 inches). This makes me think that I definitely need to plan for a substructure or adjustable feet. The furniture must be absolutely stable because the family often cooks together at the stove, so it needs to stay steady. Are there any recommendations on how to build the base so that nothing wobbles or shifts, even under load?

Hello Bukife, your concern is very understandable. For uneven floors, especially as you describe, a flexible and precise adjustment of the substructure is essential.

- First, I like to use height-adjustable screw feet for Metod. These can be individually adjusted with millimeter precision. This already allows you to compensate for most of the floor waves.
- To ensure that all cabinet modules align perfectly, I first build a complete frame from multiplex plywood sheets, cut to size and leveled precisely. This frame serves as a stable base level that can be adapted to the existing unevenness using shims.
- In the next step, you mount the individual Metod cabinets onto this base plate. This prevents individual furniture parts from moving or tipping independently.
- For wall mounting: always use secure, deep drill holes with appropriate anchors. For older walls, it is sometimes worth checking for solid areas behind plaster to ensure the anchors hold firmly. I have had very good experiences with cavity anchors or chemical anchors when the plaster is crumbly.
- Regarding baseboards: if possible, use flexible mounting systems or a combination of construction adhesive and screws to accommodate slight movements.

Finally, I strongly recommend scanning the entire floor and wall surfaces with a spirit level before assembly and recording all height points with a measuring device. This way, you plan the assembly more systematically and can avoid unpleasant surprises during installation.
