New build cracks

[EnlightenedOwl]

Is this ok it doesn't go right across and seems just hairline

Look like settlement cracks to me. How long have you been living there?

Its 1.5 years old bought from new this has been there a while got no worse

As the house 'dries out' you get cracks as things shrink!

We had these and filled them with polyfilla before painting.

Thanks its overdue for painting and filling. Totally lost confidence inclined to be a bit panicky as got an nhbc claim ongoing

That's not a big crack, certainly not structural.

Thanks just needed reassurance I will get it filled and painted but obviously can't have anyone in to do it at the moment. Just lost confidence with the nhbc claim and hearing horror stories

Nhbc warranty on new builds is worthless. They are in bed with the house builders.

I know I agree but put claim in anyway on a see what happens basis I bitterly regret buying new build tbh

Unfortunately thousands feel the same. They just didn't know exactly what they were signing up to. The contracts are written deliberately in confusing legalise with punitive clauses deeply embedded within.
That's why they try to force/tempt/threaten you to use their "recommended" solicitors.

If this is a brick and block house then there may have been thousands of litres of water used in its construction. If you then move in before a cold spell and turn on the heating you will experience numerous shrinkage cracks appearing , as shown in your pic and also around skirtings, door frames etc.
Nothing to worry about and the NHBC has its uses but in this case it won't cover this 'problem'.

Oh I know. The NHBC is for cracked masonry ( non supporting decorative stone header above window ) and leaking front door. We are under 2 year builder warranty period but now gone to nhbc as builder not interested in sorting.
