Just removed wallpaper from room we are decorating, and found quite a few cracks. A couple am quite concerned about, these are fairly large and did not notice with wallpaper on (only been in this house for 9 months)
I have chip plaster away and found the crack is though and in the thermolite internal wall, see pics.
Is this a concern? do I need a structural eng
to look .at.
The house is a 60s build, and all internals are thermolie block and under and top coat plaster.
What should I do, as I think this is not the only one in the house, do thermolite crumble and fall apart.
There are no external cracks in brickwork.
Any advice much appreciated
