Hairline cracks reappearing

callmechar

Keep finding small thin hairline cracks around the bathroom doorway which I fill and paint over but keep reappearing. I am not sure what to do.

Oddly one of the cracks which runs from about 10cm down from the top of the door frame runs horizontally across the wall from the frame.

Both cracks are thin. Only hairline and have never been wide cracks.

Should we be worried? My concern is subsidence as we have found other cracks in the house but it is an old house (60's) and has not been really done up until we purchased the house 3 years ago. So the other cracks could be old movement

It's not an old house if you mean the 1960's. It's probably just lines where plasterboards join

No it's not where the plasterboard meets.

There is one crack above the door and one from the side.

As I understand it a horizontal crack is not likely structural. The one crack from the side of the door could possibly be where the plasterboard joint is as I think that is where a door used to be and pre previous owners got rid of the door when they separated the bathroom from two rooms into one

Houses move all the time different construction materials expand and contract at different rates at different times subsidence cracks tend to show more zig zag as leaving a stepped type crack or in moon sort of shapes very rarely straight as brickwork is interlocked it tends to give at weakest point first that should be mortar

Yours sound more like stud wall moving as door opens and closes or plasterboard moving along joint if its plaster you could try putting screws in it or instead of filling it with paint which isn’t really a filler use a proper filler that expands and contracts

I've had hairline cracks like this appear when I've gone in loft. Is the area near the loft hatch or near where someone has been above in the loft? I send my teenage dd up there now as she's lighter than me.
