My new apartment has developed hair-line cracks in all the walls?

Question

Hi, I have purchased a new under-construction apartment from a reputed builder in Mumbai, India. We have moved in just about a month ago. We have observed that very fine, hair-line cracks have developed in all the walls. Reportedly, this is heppening in all apartments of the same complex. We asked the builder about it and they responded saying that this is normal for a new construction and happens due to climatic changes. They have asked us to wait for more such cracks to come in next 3-4 months and then they will repair/fill it and do the touch-up. My question is that whether this is normal and whether after the repair this will be alright? It will be great if anyone can throw light on this. Thanx.

Answer 1

it's probably from the ground moving and the foundations moving. Even if the repairs are done properly, it will probably happen again.

Answer 2

This can not be repaired with filling the cracks. The foundation of the building is settling/shifting. That is fairly normal, yes but It might not stop. You may want to have someone check out the ground underneath to see of it is stable enough to hold up the place. It may cost a bit to fix if the ground is soft but if you plan on keeping the place for a while (a generation or more) it will be worth it.

Answer 3

They could be harmless cracks; they will return with regularity no matter how often you fill them. Watch, though, for loose or crumbly cracks, holes, and bulges; these may mean you have a leak.

However, it could also be a sign of foundation trouble. You might wish to hire another contractor or inspector to take a look.

Answer 4

of course it's normal. it's expansion and contraction. are you sure the cracks are appearing in the wall or the paint?
