About Sport Court Maintenance
A sport court doesn't fail all at once — it fades a shade at a time, picks up algae in shaded corners, opens a hairline crack near the net posts, and loses its lines to UV and foot traffic until nobody can tell where the boundaries are. By the time a tennis, basketball, netball or multi-sport court looks obviously worn, the base and surface coating have usually been degrading for a season or two already. We maintain sport courts for homes, schools, clubs, estates and businesses across Germiston, the East Rand and Johannesburg: surface cleaning, crack repair, line repainting and scheduled upkeep, on tennis, basketball, netball and combination multi-sport surfaces. This is deliberately smaller-scale, lower-cost work than a full resurface or new build, and doing it regularly is what keeps your court off the repair list for as long as possible.
What's Included
- On-site check of surface, cracks, drainage and lines
- Soft-bristle broom and blower pass for debris
- Pressure wash with mild detergent for algae and grime
- Cracks checked at joints, net-posts, corners and repairs
- Acrylic filler for hairline surface cracks
- Fabric-reinforced repair for structural, reopening cracks
- Lines repainted to correct dimensions per sport code
- Drainage points and edge channels checked and cleared
Our Process
- 1
Clean the Surface
Routine cleaning is a soft-bristle broom or blower pass to clear leaves, dust and loose debris before it embeds into the acrylic coating. For a deeper clean, we pressure wash with a mild, non-caustic detergent, working section by section and rinsing thoroughly so no residue is left to attract more grime.

Inspect and Repair Cracks
Every visit includes a check of expansion joints, net-post surrounds, corners and previously repaired areas, where cracking tends to start first. Hairline cracks are filled with an acrylic filler matched to the coating colour, while structural cracks that keep reopening get a fabric-reinforced system that flexes with the movement instead of just bridging over it.

Repaint the Lines
We repaint faded or damaged lines using an acrylic marking system that bonds to the existing coating, measured to the correct dimensions for tennis, basketball, netball or a multi-sport layout. On a combination court, each code's lines stay a distinct colour so players aren't second-guessing which boundary applies.

Schedule Ongoing Upkeep
For clubs, schools and estates running a court under regular use, we set up a scheduled maintenance visit — cleaning, a crack and drainage check, and line touch-ups — on an agreed interval. Catching small issues early costs less over the court's life than waiting until it's visibly failing.

Sport Court Maintenance FAQ
How often should a sport court be maintained?
Most courts benefit from a professional inspection and clean at least once a year, with more frequent attention for courts under heavy or year-round use, such as a school or club facility. Between professional visits, a regular sweep or blow-down to keep leaves and debris off the surface goes a long way, since debris left to sit is what turns into staining and, eventually, surface damage. Courts in shaded or damp spots on the Highveld tend to need attention more often than a court in full sun, because algae and moss build up faster wherever water sits. We'll recommend a schedule based on your court's actual conditions and how much it's used, not a generic interval.
How do you get rid of algae, moss or green staining on a court surface?
Light algae or staining usually lifts with a pressure wash using water and a mild, non-caustic detergent, worked over the affected area and rinsed thoroughly so no residue is left behind. Caustic, acid-based or solvent cleaners are avoided because they can strip the acrylic coating along with the grime, which does more damage than it fixes. If algae keeps coming back in the same spot, it's usually a drainage or shade issue keeping that section damp longer than the rest of the court, and we'll look at addressing that rather than just cleaning the symptom every few months.
Can cracks in a tennis or basketball court be repaired without resurfacing the whole thing?
In most cases, yes. Hairline surface cracks are filled with an acrylic crack filler matched to the coating, and cracks that keep reopening get a fabric-reinforced repair that flexes with the movement underneath rather than just bridging over it. This works well for isolated cracking on a court that's otherwise sound. Where cracking is widespread across the surface, or keeps returning across multiple areas, that's usually a sign the base itself has failed, and at that point a repair or resurface through our sport court repairs service is the more honest fix than patching indefinitely.
How often do court line markings need repainting?
It depends heavily on traffic and sun exposure, but expect faded lines somewhere in the range of every one to three years on a regularly used outdoor court, sooner on high-traffic areas like the baseline and service boxes, and sooner still on a shared multi-sport court where several codes' lines get walked on. UV exposure fades paint even on a court that isn't used much, so age matters almost as much as use. We'll tell you honestly whether your lines need a full repaint or just a touch-up when we assess the court.
What's the difference between maintenance and resurfacing a sport court?
Maintenance is the ongoing work that keeps a structurally sound court playable and safe: cleaning, crack filling, line repainting and drainage upkeep. Resurfacing is a bigger job, stripping and reapplying the surface coating, or rebuilding sections of the base, and is what's needed once general wear, extensive cracking or a failed base go beyond what cleaning and patching can fix. Regular maintenance is what delays the point where a court needs a full resurface, sometimes by years, which is the main reason it's worth doing on a schedule rather than only once something looks obviously wrong.
