Hello,

an earthquake 30 years ago caused a crack halfway up a gable wall.
The wall is a cavity wall.
Photos may follow.

How would you approach repairing this crack?

Have you ever seen the houses?
Can you assess their structural condition?
And what exactly is being presented... without photos or any other information?

No one except you has seen the houses, and no one except you can post pictures of this crack. But you are not able to do that.

But according to your opinion, they should be demolished immediately? Others are eager to buy the property and want to renovate it for a high price. Strange, isn’t it?
Up to page 4, there wasn’t a single suggestion on how to proceed. Genuine experienced tradespeople can describe at least the usual standard procedure for such a project without even having seen anything.
That was what was asked for.
It is not a problem to include the photos, but the timing is too early.

No, they cannot. Or rather, there are 15 different approaches depending on the specific crack. Where it is, how deep, how wide, how long, etc. – with a crack that is 30 years old, the answers range from “do nothing at all” to invasive measures.
There is no “typical” procedure for unknown damage.

Correct. The timing of the question without photos is too early.

I can do that too.
The "normal, usual process" would be that the craftsman attends an on-site appointment before saying anything. Alternatively, an experienced craftsman would take proper photos, to avoid making a completely random guess. Anything else would be unprofessional, and a craftsman who just talks without seeing anything is a bluffer.

The IRONIC comment about the demolition should have pointed you exactly in this direction.

A specific piece of advice: Walk through the property together with a structural engineer. Whether the crack has structural consequences or not determines all the following measures.

To clarify again:
- I am currently not at the property
- This is only about rough suggestions regarding the procedure of the measures
- Someone else will carry out the work, not me
- I just want to understand approximately how such things are handled. The bricklayer has offered to seal the crack. Since it’s a cavity wall construction, in my opinion only the upper half would need to be taken down and rebuilt, or secured internally with steel U-channels anchored with threaded rods.
Please understand that I cannot upload any photos yet, thanks!

Can you tell me if my shoes match my trousers? Photos will follow, but unfortunately I can’t access my wardrobe right now...

Notice anything?
