You’ve invested in a professional paint job — the walls look fresh, the colours pop, and your home feels brand new again. But how long will it stay that way?
At Southern Highlands Painting and Wallpapering, this is one of the most common questions we hear from homeowners. The truth is, there’s no single number — paint lifespan depends on where it’s applied, the type of paint used, and how well it’s maintained.
In this guide, we’ll explain how long a professional paint job should last inside and outside your home, what affects that lifespan, and how to make your paint look great for as long as possible.

How Long Does Interior Paint Last?
A high-quality interior paint job typically lasts 7 to 10 years — but that can vary by room and surface.
- Bedrooms and living areas: Around 8–10 years, as they see less wear and tear.
- Hallways and high-traffic areas: 3–5 years, since they’re more prone to scuffs and knocks.
- Kitchens, bathrooms, and laundries: 3–4 years, due to heat, humidity, and cleaning.
- Ceilings: Often last up to 10 years, though stains, smoke, or leaks can shorten that time.
Interior paint generally lasts longer when applied with premium products and proper preparation — including cleaning, patching, sanding, and priming.
How Long Does Exterior Paint Last?
Exterior paint has a tougher job. It faces sun, wind, rain, and temperature extremes — all of which gradually break it down.
In the Southern Highlands, with its mix of warm summers and cool, wet winters, a professional exterior paint job usually lasts 5 to 10 years depending on surface type:
- Timber weatherboards: 3–5 years due to movement and moisture exposure.
- Brick or render: 8–10 years, as these surfaces are more stable and absorbent.
- Metal or Colorbond: 10+ years if properly prepared and painted with weather-resistant coatings.
Homes that get strong sunlight or coastal winds may need repainting sooner, while sheltered properties can often go longer between coats.
Factors That Affect How Long Paint Lasts
1. Quality of Paint and Materials
Cheaper paints fade and peel faster. Premium paints from trusted brands offer better colour retention, UV protection, and durability — meaning fewer repaints in the long run.
2. Surface Preparation
Even the best paint won’t last if applied over dust, grease, or flaking old paint. Proper preparation — cleaning, sanding, and priming — ensures a strong bond and smoother finish.
3. Application Technique
Professional painters use consistent coverage, correct brush or roller types, and appropriate drying times between coats. Skipping these steps can halve a paint job’s lifespan.
4. Climate and Environment
Harsh sunlight, humidity, and rain all wear down paint. Exterior walls that face the afternoon sun often fade faster than shaded sides.
5. Maintenance and Cleaning
Washing exterior walls annually and wiping down interior surfaces helps extend paint life by removing dirt, oils, and mould spores before they damage the surface.
Signs It’s Time to Repaint
Even if your paint hasn’t reached its “expected” lifespan, these signs mean it’s time for a refresh:
- Fading or dull colour — UV rays have started breaking down pigments.
- Peeling or flaking — Paint is no longer adhering properly.
- Cracks or bubbling — Often caused by trapped moisture or temperature swings.
- Mould or mildew growth — Common in damp or shaded areas.
- Chalky residue — Indicates the paint film is breaking down.
A professional repaint not only restores appearance but also protects your home’s surfaces from moisture and further damage.
How to Make Your Paint Last Longer
- Use quality products made for Australian conditions.
- Prep thoroughly before painting — don’t cut corners.
- Keep up with maintenance, especially for exterior walls.
- Touch up minor damage early before it spreads.
- Schedule regular inspections every 3–5 years to catch wear before it becomes costly.

Final Thoughts
A professional paint job is an investment that should last — and with proper materials, preparation, and maintenance, it will. On average, you can expect 7–10 years for interiors and 5–10 years for exteriors before needing another full repaint.
If your walls are fading, cracking, or simply losing their lustre, it may be time for a refresh. The good news? A new coat of paint doesn’t just improve your home’s appearance — it protects it for the future.
