Most New Zealand homes should have their exterior repainted every 7–10 years, though exposed, coastal or south-facing surfaces can need it sooner. The real answer is to repaint when the existing coating starts to fail — catching it early is cheaper than waiting until timber is exposed.
What affects how often you need to repaint
Exposure is the biggest factor. Sun, wind, rain and salt break paint down, so a coastal Raglan home or a sun-blasted north wall ages faster than a sheltered one. The quality of the previous paint job — especially the preparation and the grade of paint — also makes a big difference to how long it lasts.
Cladding matters too: timber moves and needs flexible coatings, while plaster and fibre-cement have their own systems. A premium repaint done well simply lasts longer between repaints.
Signs it's time to repaint
Look for fading or chalking (a powdery film when you rub the surface), flaking or peeling, cracking, gaps opening at joints, and any bare or greying timber. If you're seeing these, the coating is no longer protecting the surface and it's time to act before repair costs climb.
Frequently asked questions
Is it bad to leave it too long?
Yes — once paint fails and timber is exposed, you get rot and more extensive (and expensive) preparation and repair at the next repaint.
How often for a coastal home?
Coastal homes can need attention every 5–7 years or sooner because salt air is so hard on coatings.
