The new build snagging period is two years. A developer must fix any snags reported during this period. However, ideally a snagging survey should be done before move in day. This is to ensure that any defects found are not attributed to damage caused by the property being lived in rather than poor workmanship. Furthermore, most developers have strict rules about how and when snags are submitted and fixed. Most developers will only allow one list with no changes after it is submitted so it is best to use a snagging company.
