Hi I live in a bungalow dorma and the 2 rear bedroom have a hair line crack on the two outer walls and both sides of the inner wall (which is between both bedrooms) all cracks are in about the same position and run vertically from floor to ceiling and looks similar upstairs in the dorma would this be structure damage from the dorma. Appreciate any help

The cracks are fairly small and are probably cosmetic, although it looks like they have been painted over before.  Have you had any work done that would cause them?

There was a dorma built about that was in 2005 Iv had the house a few years now but Iv not done any work only hung a tv on the middle wall thanks for replying it looks like there are similar cracks upstairs in the dormer as well. 

May well be the dormer settling or moving - very wet weather and timber can absorb from the outside and move slightly. They seem small enough to be down plasterboard joins 

Ok thanks do you think it’s nothing to worry about then 

All downstairs is solid walls as it was built in the 50s but upstairs is timber

I would simply fill and re-paint. If they come back then investigate further. For now i wouldn't worry.

Ok will do thanks for your help 

I took away a bit of plaster and the crack looks about 2mm but this would be on 2 other walls that all line up together would this be an issue
