Many Northland homes built in the 1990s and early 2000s have cladding that needs replacing, and storms regularly bring insurance repair work. Clay soils and sloping sections mean retaining and drainage are common parts of a build.

- Check licensing – restricted building work needs a Licensed Building Practitioner.
