Court Resurfacing

Line Marking Australia resurfaces tennis, basketball, netball and pickleball courts across Australia. We repair cracks, recoat acrylic, replace worn synthetic grass and re-mark every line. A tennis court acrylic resurfacing starts from about $8,000 (Airtasker cost guide, 2026), and we tell you honestly when a court needs a rebuild instead.

Most courts don't fail all at once. The colour fades, the surface gets slippery, a few cracks open up, and the lines go grey. By the time players complain, the court is usually overdue for a recoat.

The good news is that a sound slab can be brought back for a fraction of the cost of a new court. Here's how we work out what your court needs, what it costs and how long it takes.

How much does tennis court resurfacing cost in Australia?

Tennis court resurfacing in Australia starts from about $8,000 for an acrylic recoat on a sound court (Airtasker cost guide, 2026). The final price depends on the court size, how many cracks need repair, whether the base has moved, how many colours and sports you want lined, and access for equipment.

Work	When it fits	Cost guide
Acrylic recoat and new lines	Faded or worn surface on a sound slab	From about $8,000 for a tennis court (Airtasker cost guide, 2026)
Crack repair plus recoat	Hairline to moderate cracks, no major movement	Quoted per site; we itemise the repairs
Synthetic grass replacement	Worn, flattened or torn synthetic grass	Quoted per site
Full rebuild	Failed base, heavy cracking, poor drainage	Quoted per site; new tennis courts start from about $40,000 (Oneflare cost guide, 2026)

Basketball, netball and pickleball courts follow the same logic. The surface area, the condition of the base and the number of line colours drive the price, so we quote each court after we've seen it.

How often should a tennis court be resurfaced?

A tennis court should be resurfaced about every 7 to 10 years if it's acrylic and about every 10 to 15 years if it's synthetic grass, according to Tennis Australia's Victorian maintenance guides. Heavy use, full sun, tree debris and poor drainage can shorten that, while regular cleaning helps a surface last longer.

Signs your court is due:

• The colour has faded and the surface looks chalky or patchy
• The texture has worn smooth and the court feels slippery
• Cracks are opening or water sits in puddles after rain
• Synthetic grass is flat, bald or lifting at the joins
• The lines are faint or there are old lines you no longer use

Acrylic recoat or full rebuild: which does my court need?

An acrylic recoat suits a court whose concrete or asphalt base is still sound, with only surface wear and minor cracks. A full rebuild is needed when the base has moved, cracks keep coming back, water ponds badly or the court sits on failed ground. We check the base before recommending either.

What we look at on site:

• Cracks: how wide they are, whether they're moving and whether they go right through the slab
• Levels and ponding: where water sits after rain and whether the falls still work
• Edges and surrounds: tree roots, soft edges and drainage around the court
• Existing coatings: how many layers are on the court and whether they're bonding

If a recoat will only last a season or two, we'll tell you. A rebuild is a bigger job, and our tennis court construction team handles the base, slab and new surface in one project.

How do you repair cracks in a tennis court?

Cracks in a tennis court are repaired by cleaning them out, filling them with a flexible crack filler or acrylic patch, levelling the repair and then recoating so the repair blends in. Fine cracks usually disappear under the new coating. Large or moving cracks may need a crack membrane, and some return over time.

Our usual repair steps:

1. Pressure clean the court and remove moss, dirt and loose coating
2. Rout out and clean each crack
3. Fill and level with a suitable filler, in several passes if needed
4. Patch low spots where water ponds
5. Apply the acrylic resurfacer and colour coats
6. Re-mark the lines

We're upfront that structural cracks can come back, especially on reactive clay soils. We'll explain the options and expected results before you commit.

Can you replace worn synthetic grass on a tennis court?

Yes. Worn synthetic grass on a tennis court can be lifted and replaced with new sand-filled synthetic grass, usually on the existing base if it's still level and draining. We remove the old turf and sand, check and repair the base, lay and join the new grass, add the lines and top-dress with sand.

Some clubs use replacement time to switch surfaces, for example from synthetic grass to acrylic hard court, or to add pickleball lines. Tennis Australia classifies surfaces in its National Court Surface Policy, and we follow its guidance for club and community courts.

How long does it take to resurface a tennis court?

Resurfacing a tennis court usually takes a few days to about two weeks on site, depending on the crack repairs, the number of coats, synthetic grass removal and the weather. Acrylic coatings need dry, mild conditions to cure properly, so rain or extreme heat can push the schedule out.

We give you a timeline before we start and keep you posted if weather changes it. For clubs and schools, we plan around fixtures and school holidays where possible.

Can you resurface basketball, netball and pickleball courts too?

Yes. Line Marking Australia resurfaces basketball, netball, pickleball and multi-sport courts using the same steps as tennis: clean, repair, recoat and re-line. Resurfacing is also a good time to change the court layout, add a second sport or switch to colours that make each set of lines easier to read.

Once the surface is done, we mark each sport to its court dimensions. See our multi-sport court line marking page if you want to combine several sports on one court, or our court painting page for colour choices.

Is resurfacing a court worth it?

Resurfacing a court is worth it when the base is sound, because a recoat costs far less than a rebuild and restores grip, colour and clean lines. A tennis court recoat starts from about $8,000, compared with about $40,000 for a new tennis court (Oneflare cost guide, 2026). It isn't worth it on a failed base.

Delaying a recoat often costs more in the end. Water gets into open cracks, the base softens and a cheap repair turns into a rebuild.

Are there grants for club and school court resurfacing?

Yes. Clubs and community groups in Australia often fund court resurfacing through state and council grants. For example, the Queensland Gambling Community Benefit Fund offers up to $35,000 for club projects such as resurfacing, lighting and fencing. We can provide a detailed scope and itemised quote to support your application.

How we keep every resurfacing job compliant

Every court resurfacing job we do follows the same safety and compliance steps, whether it's a backyard tennis court or a bank of club courts. These are the checks that apply to resurfacing work, so you know the court is safe to play on and the job was done properly.

• Council check: we confirm whether your council needs to approve the work, especially if fencing, lighting, drainage or levels are changing
• Work Health and Safety: Safe Work Method Statements for high-risk construction work, such as excavation and mobile plant on rebuilds
• Silica dust controls: water suppression or on-tool vacuum extraction when cutting or grinding concrete
• Sediment and stormwater controls so cleaning water and debris don't leave the site
• Before You Dig Australia check before any excavation on a rebuild
• Slip-resistant textured finishes on every acrylic coat
• Licensed builders who hold the licence your state requires, with public liability insurance
• Tennis Australia guidance for club and community tennis, and each sport's court dimensions for the lines
• School sites: work scheduled for school holidays where possible, with Working with Children checks for crews

What do you need from me to quote a court resurface?

To quote a court resurface, we need to know the court type, its current surface, its size and condition, and what you'd like it to become. Photos of the whole court and close-ups of any cracks or puddles help us give you an accurate quote faster. Tell us:

• Court type and sports to mark (tennis, basketball, netball, pickleball, multi-sport)
• Resurface, conversion to another sport or a full rebuild
• Court size and number of courts, indoor or outdoor
• Site type: home, school, club, council, strata or other
• Current surface (acrylic, asphalt, concrete, synthetic grass) and its age
• Cracks, ponding, slope or drainage problems
• Access for vehicles and equipment
• Preferred surface and colours
• Equipment, fencing, lighting or power changes
• Any approvals, plans or photos you already have
• Timing and budget
