Cracks internal wall first floor

Featured Replies

Hi all, I am looking to buy a house which has not been lived in for last 35years at least.

There are some cracks but these are the worrying one for me. I know I need to get structural survey but what are your thoughts. Any help will be greatly appreciated.

The top of the door frame crack is in bedroom three (wall shared with landing).

The crack on the side of door frame is on upstairs WC wall.

Please could you also specify which crack is more concerning.

Thanks

Typo

If there are no cracks evident outside it may be no issue. Make sure your structural survey look at these.

I'd look hardest at the last 2, as they show a step-crack on brick. The earlier ones seem to be due to a change of substrate.

This is from distance before the bricks were expised. Could this be simply lintel failure. Can't see the same crack going down to the ground floor so that reduces the risk of it being subsidence.

I am assuming lintel failure is relatively easier fix than subsidence. Please correct me if I am wrong?

Just for context this is where the crack is located circled in red (so it's an internal wall).

Which way does the ridge run - front to back or L-R? If L-R you could maybe have purlins bearing on those 2 walls above the bedroom ceilings. We need more pics.

Does this help? Unfortunately I don't have any more photos and the ridge seems to be combination of both L-R and Front to Back. It's just at that junction. The cracks are above both bedrooms doors IE Bedroom 3 and Bedroom 1. 4th picture on original post was bedroom 1 and 5th picture bedroom 3. These wall seems to be alongside the L-R ridge. What does this mean if its a load bearing wall? Are we saying this is not just lintel failure IE this is more and fix will be lot more costly? Any idea of complexity or scale would be good. Thanks.
