How to Maintain a Netball or Tennis Court for 10+ Years

Building a sports court is an investment—but keeping it in great condition is what ensures it lasts for many years. Whether you’re managing a school, sports club, or community facility, regular court maintenance can prevent expensive repairs and keep your players safe.

At William Gift Civil (Pty) Ltd, we don’t just build courts—we also help you protect them. Here’s a complete guide to maintaining your netball or tennis court for 10+ years in South Africa’s climate.

Weekly Maintenance Checklist

1. Sweep the Surface
Remove dust, leaves, and litter with a soft outdoor broom or leaf blower. This prevents buildup that can trap moisture and cause mould or algae.

2. Inspect for Early Cracks
Hairline cracks should be sealed quickly to prevent water from entering and widening them.

3. Clear Drainage Channels
Blocked drains or edges cause puddles. Always ensure water flows off the court properly.

Seasonal Maintenance Tips

Rainy Season (Spring/Summer):

• Check for standing water after rain

• Pressure wash the court if algae appears

• Watch for weed growth along edges or cracks

Dry Season (Winter):

• Apply crack sealant to prevent expansion

• Repaint faded lines if needed

• Schedule resurfacing during dry periods for best results

How to Know When It’s Time to Resurface

You should consider resurfacing if:

•The surface has multiple cracks or low spots (puddling)

•Players complain about poor bounce or grip

•The coating is faded, slippery, or peeling

•It’s been over 5–7 years since the last resurfacing

Resurfacing doesn’t mean rebuilding. Most of the time, we simply clean, seal cracks, apply an acrylic coat, and repaint lines—saving you thousands of rands.

Mistakes to Avoid

•Using high-pressure washers too often – this can wear down the coating

•Letting water or moss sit too long – leads to surface breakdown

•Ignoring loose posts or leaning fences – these are safety hazards

•Delaying small repairs – minor cracks become major issues if neglected

We offer once-off or scheduled maintenance visits to:

•Inspect and patch cracks

•Treat for weeds, pests, or mould
