Uneven floor repair Sydney — diagnosis, levelling and fix

Most uneven Sydney floors are repaired in 1–3 days using a combination of substrate inspection, structural repair where needed, and self-levelling compound or screed to restore flatness.

Uneven floors in Sydney homes are usually caused by failed substrates, slab subsidence, or original installation defects. We diagnose the cause first — then specify the right combination of structural repair, screed, and self-levelling compound to fix it for the long term.

What this service delivers

  • Diagnostic substrate inspection before quoting a fix
  • Structural repair where slab or joist movement is the cause
  • Self-levelling or screed system selected for the actual problem

Frequently asked questions

What causes uneven floors?
Common causes include slab subsidence, joist movement, failed magnesite, water damage, and original installation defects — each requires a different fix.
Can self-levelling compound fix any uneven floor?
No. Self-levelling fixes thin corrections; deeper or structural problems need screed or substrate repair first.
How do you diagnose the cause?
We inspect the substrate, check moisture, measure slope, and assess movement patterns before recommending a fix.
How long does an uneven floor repair take?
Most residential repairs complete in 1–3 days; structural cases may take longer if engineering input is required.
