How Long Does Exterior Paint Last on a House?

November 13, 2025
Keeping your home’s exterior looking fresh isn’t just about curb appeal - exterior paint plays a crucial role in protecting your property from Perth’s intense sun, wind, and rain. Many homeowners wonder, how long does exterior paint last on a house? The answer depends on several factors, including paint type, surface material, and the quality of the application. Understanding these elements can help you plan your repainting schedule and maintain your home’s condition for years to come.

Typical Lifespan of Exterior Paint

On average, exterior paint lasts between 5 to 10 years. However, this range can vary significantly based on surface type and environmental exposure.
  • Timber weatherboards may require repainting every 4–7 years due to expansion and contraction caused by temperature changes.
  • Brick and render surfaces tend to last longer, typically around 8–12 years, since they’re less prone to moisture absorption.
  • Metal surfaces, like gutters and fences, usually last around 5–8 years before fading or rusting appears.
In Perth’s hot, dry climate, UV rays and temperature extremes can accelerate paint deterioration, especially on north- and west-facing walls that receive the most sun exposure.

Factors That Affect How Long Exterior Paint Lasts

Several factors determine how many years your exterior paint lasts before it needs refreshing:

Surface Material

Porous materials like timber absorb more paint and require more frequent repainting than non-porous surfaces such as brick.

Preparation Quality

Proper cleaning, sanding, and priming before painting make a significant difference in how long the finish lasts. Paint applied over dirty or flaking surfaces won’t adhere properly.

Paint Type

High-quality acrylic or elastomeric paints are designed to withstand UV damage and resist cracking, peeling, and fading.

Climate and Weather Exposure

Perth’s combination of strong sunlight, coastal winds, and occasional storms can reduce a paint job’s longevity if inferior products are used.

Application Method

A skilled painter applies even coats and ensures correct drying times. DIY applications often miss these steps, leading to premature paint failure.

Signs It’s Time to Repaint Your Home Exterior

Even the best paint eventually wears down. Recognising the early warning signs helps you schedule a repaint before damage worsens:
  • Fading or Chalky Paint: UV exposure breaks down pigments, leaving a powdery residue.
  • Peeling, Cracking, or Bubbling: Often caused by moisture trapped under old paint or poor preparation.
  • Exposed Timber or Rust Spots: Indicates that your paint’s protective layer has failed.
  • Mould, Mildew, or Stains: Common in shaded or damp areas, showing that the surface is retaining moisture.
If you spot any of these issues, it’s time to contact a professional painter for an inspection and repaint before costly structural repairs are needed.

How to Extend the Lifespan of Your Exterior Paint

While repainting every few years is inevitable, you can significantly extend the life of your exterior paint with some simple maintenance habits:
  • Wash Your Walls Annually: Use a soft brush and mild detergent to remove dust, grime, and pollutants that can degrade paint over time.
  • Inspect Regularly: Check for cracks, flaking, or water damage after each season. Early intervention prevents small issues from becoming major repairs.
  • Trim Nearby Plants: Overgrown trees or vines trap moisture and rub against paint, causing wear.
  • Choose Premium Paints: Invest in high-quality paints formulated for UV resistance and Australian weather conditions.
Schedule Professional Maintenance: Even a quick touch-up every few years can refresh your home’s appearance and extend the life of the existing paintwork.

How Often Should You Repaint?

The best way to know when to repaint your exterior house is to monitor both the condition of the paint and the age of your last job. As a general guide:
  • Timber: Every 5–7 years
  • Brick/Render: Every 8–12 years
  • Metal: Every 5–8 years
If your home faces harsh coastal winds or constant sun exposure, you might need to repaint more often. Regular upkeep not only protects your property but also maintains its street appeal - something that’s especially important if you’re planning to sell or rent your home.
