There are cracks in my new build home, what do I do?
Over time, once your home is lived in, heated timber and other materials will shrink and this can cause cracks on walls, ceiling finishes and floor finishes.
These cracks are not structurally significant and can be rectified in the normal process of decoration. As such cracks are inevitable, the builder is not required to rectify them.
To minimise cracking you should keep a reasonably even temperature throughout your home, even in rooms which are not used as often, so that the structure of your home warms up and dries out gradually. Depending on weather conditions this may take several months.
