Cracks in exterior wall

[Daveoakley]

Hi. I’ve noticed the below cracks in my exterior walls (extension from 1983) and the rear wall. Any thoughts what could be the cause ?? The cracks run diagonal on each side wall of the extension, on one side they start high, other they are low. On rear house wall it is mid height...

Any internal damage anywhere?

There was cracking inside too

Any large trees / large shrubs anywhere near the affected areas?

Do you know what type of ground your property is sitting on? Clay? Sand?

Any recent [within about one year, or even longer?] blocked drains, any type of drain?

Hi-no trees or large shrubs. There is a drain but unsure of any issues as only moved in a year ago

Tried to highlight where crack is running

Similar on this side of the extension.

If you has a Survey when you purchased the property, was there any mention of cracks either inside or out in this survey?

Have you noticed any undulations or loose paviours in the drive, especially near the rain water down pipe?

Sorry for all the questions, but these questions are [generally] what an Insurer would ask if you were to intimate a claim, it is all background and history .
