Cracks in Bedroom

[old wrinkly]

Some twenty odd years ago we hade an extension built that included a new bedroom, new en-suite and a small room with access from the outside that acts as a store room.

The dividing wall between the bedroom and ensuite was built using white building blocks (Celcon?).

We had a leak in one corner of the bedroom where insufficient lead had been used to protect the gully and this damaged the coving in that corner.

The coving is now splitting from the ceiling around about 70% of the ceiling and there are some siginificant cracks on the wall between the bedroom and en-suite.

We have a plasterer coming in to replace the coving and he is going to chase out the cracks and back fill. He said when he came that he wasn't sure why the cracks have appeared as there seemed not to be any other cracks i.e the tiles in the en-suite and there shouldn't be any issue with subsidence. The plaster has not blown.

He also said that if the cracks came back he would recommend getting a builder in to take a look from a building perspective.

Anyone have any ideas?

Thanks

Did he do the tap test to see if the plaster has blown? If so, it'll need hacking off in those areas and re doing... Back to brick if necessary.

Yes he did the tap test and said it hadn't blown. Is going to try the repair I mentioned rather than a full blown down to brick repair to avoid mess for us. Hopes that might work but!!!!!

Is he skimming the whole wall or just filling and patching? If skimming he could put some scrim tape into the plaster along the crack.

Filling and patching. Did mention the scrim tape but again was worried about the mess this would give us (we are both 80 plus) so picked what he hoped would be the less inconvenient route.

Well, it's worth a suck it and see before more extensive works I suppose.

Thanks, that was his view but will have to see. If it doesn't work will have to consider more drastic action. He was really baffled as to why the plaster had cracked which is worrying.

With very dry summers last few years, been a lot of issues with ground drying out and shrinking, maybe that or difference in ambient temps between your ensuite and bedroom... Who knows... Nothing lasts forever.
