Extension vertical crack

[cheshireblue12]

Hi I wonder if anyone can help with some advice ?

We had a two storey extension built to extend kitchen and build a third bedroom approx 5 years ago. I have noticed a vertical crack appear in the extended kitchen area where the side gable wall joins the front wall. The crack is approximately 1mm and has run a long the vertical length of the plastered walls.
Can anyone give me some advice whether this is a major concern or am I becoming a little paranoid.
All advice gratefully accepted.

You need to post photos.

You need to post photos.

Thanks for the reply,
See photo attached (best I could do with poor light). The photo needs rotating through 90 deg to show true to life.
Cheers

Not especially clear but 1mm wide wouldn't bother me much. I'd fill it and see if it opens up again.

When my kitchen extension was built the same happened and I put it down to settlement so just left it but kept my eye on it. 20years later it's still the same. The same thing happened to both my nieghbours extensions so if I was you I wouldn't be concerned.

The photo is useless. But if the crack is only 1mm its nothing to be concerned about. As mentioned just fill it and keep and eye on it.
