I have a two storey extension that was done to my house well before I bought it (at least 12 years ago).
On the first floor there is a crack on the side wall both exterior and interior. It is plaster-breeze block-pebble dashing. Interior it just runs along the corner. Exterior crack is about 2m in length, about 3cm wide in widest point but most of it it is 1-3mm wide. There is no sign of any issues on ground floor.
Insurance company arranged a video call with building consultant who concluded that it wasn't subsidence and nothing covered under insurance, he said it was very slow movement of the side wall pushing against the back wall. He verbally said to me he would just peel back the plaster, repair the cracks from inside, put some metal supports in place then re plaster. Outside is in a really awkward position to get to.
I've now had a builder round to quote for the work and he's said he can do the inside only but would recommend doing outside as well and it should be covered under the insurance.
This has left me a bit confused what to do.
So my question is do you think it's worth just doing the inside? Or am I just going to get into issues again in a couple of years time.
I've attached some pictures as well.
