How Often Should You Repaint a House in Melbourne?

There is no single answer to how often a house needs repainting, but there is a useful rule of thumb and a set of signs that tell you when your particular home is due. Here is how to read it.

The rough rule

In Melbourne's climate, a well-prepared **exterior repaint generally lasts around 7 to 10 years**. Interiors last considerably longer and are usually repainted for how they look rather than to protect anything. That range is a starting point, not a guarantee — several things push it shorter or longer.

Why some walls fail faster

Exposure

The sun and the weather do the damage. North and west-facing walls that cop the afternoon sun fade and chalk faster than shaded southern elevations. Walls that catch driving rain or sit under a leaking gutter fail sooner still. It is completely normal for one side of a house to need attention years before another.

Surface

Timber and weatherboard move with heat and moisture, so their paint flexes, cracks and sheds earlier than paint on rendered masonry or brick. A weatherboard home will usually want attention before a rendered one of the same age.

Preparation last time

This is the hidden factor. A repaint done over poor preparation — painted onto chalky, dirty or flaking surfaces — can start failing within a couple of years, no matter how good the paint. A properly prepared repaint reaches the longer end of the range. It is why the cheapest quote often costs more over a decade.

The warning signs

Rather than counting years, watch the house:

- **Fading and chalking** — colour looks flat, and a wipe leaves powder on your hand - **Flaking and peeling** — paint lifting, especially on timber and at edges - **Cracking** — fine crazing or larger cracks in the coating or render - **Bare timber or render** — any exposed surface is unprotected and degrading - **Mould and staining** — common on shaded, damp elevations

Bare or flaking areas matter most, because they let water into the timber or render underneath. Catching a repaint before that stage is far cheaper than repairing damaged building fabric later.

Don't wait for total failure

The cheapest time to repaint is just as the old coating is wearing out, not years after it has failed and let moisture into the structure. If your home is heading toward the 7-to-10 year mark and showing a few of the signs above, an inspection will tell you whether it is due now or has another season or two in it.
