Removing supports after installing steel beam

Tucker

On mine they did stay in for a couple of days, but only because the external skin wall was bricked up above the steel with new brickwork and mortar to fill the void.

The internal wall was packed with slate, but of course the externall wall needed time for the new brickwork to go off before the props could be removed.

Some cracking and movement above a new steel is normal, depending on the length of the beam. Mine was 5 metres and there were some hairline cracks in the plaster in the bedroom above. The structural engineer warned me to expect it.

It was filled and painted and has been fine for 3 years since.

I'll tell you another take on this.
My daughter had a supporting wall removed from her present house, the jacks were put in place and everything was packed up tight, left for a couple of days and the jacks removed.

Unfortunately the builders were a little to exuberant with the jack screws, the bedroom door in the wall directly above had been distorted by about 1/4" and the plaster/brickwork above it cracked:eek::eek:

Whatever building work is done there is always going to be a slight settlement somewhere. A couple of hairline cracks are nothing to worry about. A quick application of filler and the problem has disappeared forever.
Some people do seem to have to have something to panic about. I suppose that is because of general ignorance of how buildings are constructed.

Hair line cracks are 1 thing, bricks parting are another, not to mention jammed doors in our case.
