Hairline crack after plastering

I had house renovated in July including New plastering. After two months I notice now hairline cracks appearing in several places. I asked the builder to come and look at it . He is asking to pay him for mending the cracks. Am I required to pay for this, as this is due to his initial plastering?
Do you normally get hairline cracks after plastering? Pease could you give advice on this.

"As a rule you don't get them on fresh board, but on stuff that's got paint or artex it could happen, and not totally be the plasterers fault also if you had the house with the radiators on it wouldn't help, but the main thing if you expose the crack, and it was on fresh plasterboard and the crack is on where the plasterboard meets this needs a skim specially for this purpose if it hasn't got it its totally the plasterers fault hope this helps"

"Plaster shrinks and cracks will appear get a good filler and put over cracks with a paint scraper sand back and repaint"

"Of course your get hair line cracks plaster is a hand finished product and is only applied to roughly 2-3mm,

A house moves lots and lots due to temperature change
If its in the corners then there's a possibility he's not scrim taped the edges which in that case should of at a minimum chalk around edges ( wouldn't recommend this )

Plasterers are not magic but then again builders aren't plasterers"

"If fibre tape is not applied on all joints before plastering you will get hair line cracks"

"No you don’t often get cracks in plastered walls. If you have had a lot of work done some being structural then things will need to settle, and then cracks will appear. This is normal. Realistically yes the builder should fix the problems, but if it is not stated in the quote then I’m afraid he doesn’t have to come back to repair the cracks."

"You should not need to pay anything it should be covered by a Guarntee. Also if there are cracks appearing it sounds like they have used a sand and cement product which Typically will fail within the first year or so, We only use a polmor based products as they last in excess of 10/15 years.Also you should never use any contractors that do not have an Insurance backed Guarntee , If you have any further questions please feel to phone scotia Installations, We also supply render roofing roughcast windows and doors"

"First and foremost it is the builders responsibility and you shouldn't be paying any more money , sometimes you get hairline cracks above doors and windows , this suggests that the builder has not applied a mesh fibre tape where required, to prevent cracks therefore the hairline cracks need cut out at least 10cm either end of cracks, and a fibre tape put over the cracks and refilled .Cracks appearing have nothing to do with client so the builder should rectify at his expense ????"

"Yes sometimes it happens specially if there is movement in the building,I tend to rake the cracks out then fill it with dry wall adhesive that helps"

"This can happen from time to time in older buildings, unfortunately this could be caused by movement if other work ongoing. He has an obligation to sort this out for you."
