This is a new build, and there are several cracks appearing in various locations.

Here are my questions for you:

  • What is causing this?
  • Will these cracks continue to grow wider or larger?
  • How can this be prevented or permanently concealed?

Thank you in advance.

First of all, thank you for your feedback. In the past, I have unfortunately experienced a lot of different kinds of stress. Because of this, my nerves are quite frayed. I therefore prefer an independent and reliable opinion rather than one from the agent or owner.

So far, everything has been handled only through the agent, as they are also the property manager. At first, he told me this was a very good sign. According to him, the apartment is not damp, and these cracks are likely caused by drying.

Over the weekend, he informed me that the issue is related to the foundation slab.

I just want to find out how serious these cracks are, since I have not yet moved in.

As I see it, these are basically just hairline cracks and are generally harmless. The crack near the window is due to the missing plaster tape. Since the window moves when opened and closed, a plaster tape is usually installed there to absorb this movement. Plaster is rigid and cracks if something moves.

The agent's argument that you can determine moisture content from a crack is nonsense; he just wanted to avoid any hassle.

Just my two cents.

As I see it, these are basically just hairline cracks and are harmless. The crack near the window is due to the missing plaster beads. Since the window moves when opening and closing, a plaster bead is normally installed at this location to absorb this movement. Plaster is rigid and will crack if something shifts.

The real estate agent’s argument that you can determine moisture levels from a crack is nonsense; he just wanted to avoid any trouble.

Just my two cents.

These are hairline cracks. Typically, such cracks are excluded from warranty coverage in construction contracts.

At least that’s the case here. This is quite normal because the house is still settling, but everything needs to be finished quickly.

Don’t worry about it if you are a tenant.

One example is a clearly visible drying crack near the switches; below them are grooves heavily filled with plaster. When the plaster loses its water content, it naturally shrinks a bit. If you feel that the shrinking process is finished, usually after about 6 months, you can seal it tightly with some Moltofill or similar compound using an old credit card or something similar, then dab paint on it, and it’s done.

I would also call these hairline cracks! They appear and are not serious. They often don’t get any worse.

The issue here is that a standard wallpaper, like fleece or textured paint, could cover them up. But in this case, there is a firm decorative plaster that does not compensate for unevenness. If you want to rent the apartment, it might be worth asking the landlord to do some additional filling so that you rent a clean, paintable wall.

Everything in the building/apartment should be intact. If necessary, take photos with the date visible beforehand, which you can use later when moving out if needed. Otherwise, it is the owner’s or property manager’s responsibility.
