Moved into a new build last week and had a snagger round at the weekend. He noted various relatively minor things and a large number of screw pops - literally every wall/ceiling has numerous. Not super visible unless looking for them. We've talked to the builder about the list and they're mostly fine to fix stuff, but they're saying the screw pops would only be fixed if they are very visible and there's an excessive number in one area. Our house had sat for a few months after being built and the builder is saying this is why there are screw pops - due to normal settling. The snagger has said that is really unacceptable and that moving into a new build the house should be made perfect, the fact that it sat for a while is their problem not ours. Is the snagger right? We just want to make sure we're not being fobbed off.
