How Often Should You Repaint Your House in Gauteng’s Climate?

Painting your home isn’t only about looks. In Gauteng’s tough climate, regular repainting protects your walls from damage caused by sun, rain, and temperature swings. But how often should you repaint?

Peeling and weathered paint reveals the layers of time on an old wall, showcasing a tapestry of textures and faded colors.

Exterior Walls

• Every 5–7 years is a safe guideline.

• The Highveld sun fades paint quickly, especially lighter colours.

• Afternoon storms cause water streaks and can damage cheaper paints.

• North-facing walls usually need repainting first because they take the most sun.

  
  

Interior Walls

• Every 7–10 years if you use quality paint and live in low-traffic areas.

• High-traffic rooms (passages, kids’ rooms, kitchens) often need repainting every 3–5 years.

• Bathrooms may need it sooner if there’s damp or mould.

  
  

Roofs and Boundary Walls

• Roof coatings last around 5–8 years, depending on quality and exposure.

• Boundary and perimeter walls often need repainting sooner than the house itself because they get more weather and dirt exposure.

  
  

Signs It’s Time to Repaint

• Paint is fading, peeling, or chalking.

• Damp patches or mould spots are showing through.

• Cracks are forming in the plaster.

• Walls look dirty even after cleaning.

  
  

How to Get the Best Lifespan

• Use professional surface preparation (filling cracks, cleaning, priming).

• Choose high-quality, UV-resistant paint for exteriors.

• Stick to paint colours that handle the Highveld sun better (mid-tones over very dark shades).

• Wash walls and touch up small chips before they spread.
