Our 3 bed bungalow was built in 1985. Exterior walls are brick on concrete foundations and the internal walls are breezeblock on concrete slab. We have clay soil and a oak tree 12m from the point of the closest wall crack. All our cracks are on internal walls (not loadbearing) and the 3 which are the worst we have taken pictures of.
Bedroom 2 This crack started 20 years ago, was polyfilled 15 years ago, and then left as the room is unused, it runs up corner from skirting board but doesnt quite reach coving, it is 2mm at its widest point. However the crack has gone through the wall into our main bedroom. We polyfilled our bedroom wall crack 2 years ago but it showed as a hairline crack again after 12months.
Bedroom 3This crack has been evident for some 10 years, has got progressively worse runs from skirting to 1ft below coving, is at its worst around radiator approx 1.5mm wide, it is now showing as hairline crack otherside of wall in our lounge.
The hall crack is 2mm at skirting travels up wall and then splinters off into 2 hairline cracks across wall and also upto coving.
As they are internal wall cracks (we have checked and have no external wall cracks) how do we fix them to stop them coming back. We have always just painted our walls and do not want to paper over. However we do not want to keep having to fill cracks up. Possible causes would be appreciated, along with suggestions for repair. Many thank
