Hi,
I wonder if anyone has experienced (or could advise on) the following.
Last summer my sister had the lounge of her Semi re-plastered.
Just after Christmas I noticed a diagonal crack had appeared in the plaster on the party wall around 1mm in width and wider at the top than the bottom.
It has also cracked the coving at the top of the room.
I examined the wall in the eaves above the ceiling where the cracked plaster is located and have noticed that there seems to be a lot of mortar missing (In places I can see right into the wall cavity).
The damaged area had been obscured by hardboard so I assume the previous owner knew about these cracks and decided to hide them.......
The house is built on clay soil.
Should we be overly concerned here or should I just repair the cracked plaster and monitor the situation?
I am concerned that the plaster crack has occured over a short (3 month) period.
Cheers.
