Is it normal to install a windowsill (granite slab) on a single drywall (only 1 layer of drywall)?

Sounds strange that there isn't a beam under the window.

Of course there is a beam there somewhere but not where they originally put the screw and I have to fix and tweak things there anyway, so I might as well reinforce and put it back in the same place.

We have the consoles that were in a picture on page two and they work well. Of course, there must be a rule right under the window. It is possible that it is placed far inside.

I would personally be cautious before tearing into an external wall like yours. There is probably a vapor barrier behind the plasterboard that you shouldn't destroy.

An alternative solution is to attach with existing brackets, long screws, and install a radiator cover that sits in two or three supports which go between the board and the floor, at the front, not against the wall.

Place three 30*30 mm pieces as support, attach the radiator cover to these two sections, then it looks as if it is supposed to be like that, a bit of a makeshift solution but an alternative.

Hi!
In the apartment I moved into, I discovered that one of the window sills was leaning a bit askew. I investigated and quickly noticed that the window sill (the granite slab) was mounted on a wall with only 1 plasterboard (single gypsum wall) without any reinforcement (plywood, screwed into a stud, OSB) behind. Completely useless construction, it takes just a little leaning against it, or curious kids climbing on it, for it to come loose with the result of large holes in the wall.
Is it standard to build this way?
Do you have any tips on remedies? It must be reinforced behind. I have a solution in mind but would like to hear more ideas.

Let me clarify.
At the top of the bracket is the window rule and at the bottom of the bracket is 1 layer of plasterboard, nothing else. This means you'll have a leverage effect on the lower edge of the bracket if, for example, you were to place a slightly too heavy flowerpot on the windowsill, which in itself is a heavy granite slab.

This means that you get a leverage effect against the lower edge of the console if, for example, you were to place a slightly too heavy flower pot on the windowsill, which itself is a heavy granite slab.

Certainly, I am fully aware of that, but read my post again.
If you attach the bracket against the wall, it sits well against the wall in the edge of the frame, put a heavy windowsill there, and everything collapses.
If you brace vertically, between the floor and the windowsill with "studs" of adapted size, they support the weight of the slab. The studs should face outwards into the room, not against the wall.
The point is to hide the function of the studs with a nice radiator cover, nothing else.

Best regards, P-A

It is best to ask the association if you can remove the plaster to make the inner layer of the outer wall more stable. The construction they have done is completely unacceptable, no thought behind the construction except for economic gain. Wrong, no, just stupid... I hope it works out for you. Best regards, P-A

I understand P-A, it's not a bad idea. It wasn't you I was clarifying for, it was for those who needed it. Thanks again for the tip/Jack

Exactly. I'll probably have to take it up with them. It will probably end up fine. Thanks/Jack

Just wanted to give some input before the holiday season:
It's frustrating when mishaps occur, it doesn't matter if you have a newly built house/apartment, there often arise minor or major problems over time.
I myself have an old farm where most things can and have gone wrong.
I have worked with everything from fine carpentry to building restoration.
When you know what you're getting into when acquiring an older property, setbacks don't frustrate you as much.
Now you seem to just want help, not as desperate as many can get when walls are falling apart.
Stay calm, there will be more problems, guaranteed, but there are always solutions, maybe not always quick solutions, but solutions do exist, always.

I really hope you solve your little mishap; don't make it into a bigger issue so that you end up living in a construction site during Christmas, it can be taxing in various ways.
Gather information, explore different proposals, start the project when you know how you want it to be, take it slow!

Have a pleasant first Advent, feel free to continue your thread, some pictures when you start the renovation can always be fun.

Best regards, P-A

Exactly the right attitude P-A, I’m probably there myself. Fully renovated my last apartment, there were problems almost all the time and it all turned out really well, so this will be a breeze as soon as I get started. Will post pictures when I tackle the mess. Take care//Jack

Hello!
In the apartment I moved into, I discovered that one of the windowsills was hanging a bit crooked. Upon investigation, I quickly noticed that the windowsill (granite slab) was mounted on a wall with only 1 layer of drywall (single drywall) without any reinforcement (plywood, screwed in a stud, OSB) behind it. A totally useless construction, it's enough to lean against it a bit, or have curious kids hanging on it, for it to come loose, resulting in large holes in the wall.

Do you have any advice on how to fix it? It definitely needs reinforcement behind it. I have a solution in mind but would like to hear more ideas.

Sorry everyone! I probably explained the problem a bit wrong. It was so long ago that I discovered it, and I've probably forgotten the details about it all. And I was probably a little tipsy yesterday too... The windowsill bracket was well screwed into the window frame, yes. The problem lies in the fact that the underside of the bracket is supported only by 1 layer of drywall without any reinforcement behind it. This means that if the slab is heavily loaded, the underside of the bracket gets pushed into the wall... Once again, sorry for being unclear//Jack
