What causes cracks in a tennis court?
Two main causes. Surface-level cracking comes from UV degradation, thermal expansion, and the natural ageing of the acrylic coat. Structural cracking indicates base movement: subsidence, soil shrinkage in dry summers, or drainage failure beneath the slab. The repair approach is different for each, which is why we assess before we scope.
Can cracks be repaired without full resurfacing?
Often, yes. Minor surface cracking can be filled, sealed, and colour-matched without a full re-coat. Structural cracking usually requires base repair first, and once the base is stabilised, the surface is often in poor enough condition that a full re-coat makes more sense than patching. We'll give you an honest assessment during the site visit.
What is a birdbath and how is it repaired?
A birdbath is a depression in the court surface, caused by base subsidence, where water pools after rain. The fix is not a surface patch. It requires levelling the base at the point of subsidence, then resurfacing the affected area. Left untreated, the pooling accelerates cracking and creates a slip hazard.
How do I know if my court needs repairs or full resurfacing?
If the surface has widespread cracking, significant colour loss, or multiple areas of damage, a full resurface is usually more cost-effective than multiple individual repairs. If the damage is isolated (a single crack run, a loose post, a patch of line marking), repairs alone may be sufficient. We'll tell you which during the site visit.
Do repairs require a building permit?
For standard repair work (crack filling, drainage correction, line marking, fencing) a permit is not required. If your property is subject to a Heritage Overlay and the scope involves structural changes to fencing or the court's physical boundary, council advice may be needed. We flag this during the site visit.
How long do repairs take?
Crack repair and line marking typically take 1 to 2 days. Drainage correction and birdbath repair: 2 to 4 days depending on the extent of base work. Fencing replacement: 1 to 2 days. We confirm the timeline in the written proposal.
