Is it normal to install a windowsill (granite slab) on a single drywall (only 1 layer of drywall)?
Hi!
In the apartment I've moved into, I discovered that one of the windowsills was slightly slanted. I investigated and quickly noticed that the windowsill (granite slab) was mounted on a wall with only one gypsum board (simple gypsum wall) without any reinforcement (plywood, screwed into a stud, OSB) behind it. It's a completely worthless construction; it only takes leaning against it a little or having curious kids hanging 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 for a solution? It must be reinforced behind. I have a solution in mind but I'd love to hear more ideas.

New or old house ??? Newly renovated or original ??
It sounds completely wrong. You don't mount anything in plaster other than the occasional painting. Window sills should definitely be attached to studs.
Rental apartment or condominium
Rental apartment: the landlord's problem,
Condominium: your problem, you know who did it, it probably doesn't matter who did it, such defects come as a bonus when buying.
To fix it again, drill deep into the wall with 2 holes on each bracket (might have to drill new holes in the bracket), long screws and plugs, and some form of wooden piece as a spacer behind to the wall.

What do you mean by long screws/anchors? It won't help at all if the only thing there is the drywall. If it's not possible to attach the brackets to the wall studs, the only reasonable solution is to remove the surface layer and add noggings.

Moly plugs can hold quite a bit. Should work.
But it's best if you can move the brackets so you screw into the stud.

Molly plugs can hold some, but not for a window sill. Consider the torque that occurs when someone hangs on or leans against it.
Molly is not stronger than the board they're in. If it were double plasterboard maybe, but never in a million years with single plasterboard. I wouldn't use molly in double plasterboard either.

I understand that it's my responsibility to investigate, and I actually pointed it out during the apartment viewing. They knew nothing, of course... I know I can handle this, so it's not really a big problem. BUT, I am a professional demolisher, however, not a carpenter... I want to know, is it really built like this, or could this be called a botched construction? I would never mount the TV on the wall, for example. And tips for solutions, please.L Liteavvarje said:

If I have to move the brackets, I need to drill new holes in the slab, not a big issue but I still have to fix the wall and was thinking that I should cut open, insert plywood as reinforcement behind, and then reassemble everything...J jackolako said:
No need to drill more than 12 mm to go through the plasterboard everything is hanging on. Do you mean I should drill straight out through the facade then? I think I'd probably hear a thing or two from the association then...L Liteavvarje said:
