How Often Should You Repaint a House in Melbourne?

"How often should I repaint?" is one of the most common questions we get, and the honest answer is: it depends on the surface, the exposure and how well the last job was done. But there are reliable rules of thumb, and there are warning signs worth knowing.

The general guide

In Melbourne's climate, a well-prepared exterior repaint generally lasts around **7 to 10 years**. Interiors last much longer — often **10 to 15 years** — because they are protected from the weather and only really suffer from wear and marking.

Those numbers assume the previous repaint was done properly. A rushed job over poor preparation can start failing within a year or two, which is why the quality of the work matters more than the brand of paint.

Why some walls fail faster

Not all elevations weather equally. The factors that shorten a coating's life are:

- **Sun exposure.** North and west-facing walls cop the most UV, which breaks paint down fastest. A shaded south wall can look fine while a west wall on the same house is chalking. - **Driving rain and wind.** Weather-facing walls take more moisture and wear. - **Surface type.** Timber moves with heat and moisture and fails at joints and end-grain first, so weatherboard homes tend to need attention sooner than render or brick. - **Colour.** Dark colours absorb more heat and can fade faster on exposed elevations.

This is why a home rarely needs its whole exterior redone at exactly the same time — but doing it all together keeps the finish uniform and is usually more economical than repeated partial jobs.

The warning signs

Rather than counting years, watch the paint itself. It is time to repaint when you see:

- **Chalking** — a powdery residue on the surface when you rub it. - **Fading** that is noticeably uneven across elevations. - **Cracking or flaking**, especially at edges, joints and around windows. - **Peeling**, where the coating lifts away from the surface. - **Bare or greyed timber** showing through — a sign the protective coating has gone.

Why not to wait too long

On an exterior, paint is not just cosmetic — it is the barrier that keeps moisture out of the building fabric. Once a coating fails and bare timber or render is exposed, water gets in, and timber rot and render damage cost far more to repair than a repaint would have. Repainting on time is genuinely cheaper than repainting late.

The practical takeaway

Use 7 to 10 years as a prompt to inspect, not a hard deadline. If the paint is still sound, you have time. If you are seeing chalking, cracking or bare timber, it is time — and getting an inspection done means you learn whether there is any repair needed before it turns into something bigger.
