Got a failed waterproofing job? Here's what it costs to fix.

If water is escaping the wet area, bubbling paint next door, soft skirting, mould bloom, the original waterproofing has failed. Here's the realistic Sydney cost to put it right, by severity.

Minor, surface remediation $5,000-$12,000 Visible mould or efflorescence, no damage to adjacent rooms. Strip wet area, re-membrane to AS 3740, re-tile.

Moderate, subfloor or wall damage $12,000-$25,000 Water has reached the subfloor, plasterboard or adjacent walls. Includes substrate replacement, treatment and re-build.

Severe, structural rebuild $25,000-$40,000+ Multiple rooms affected, framing rotted, ceilings below damaged. Full strip-out, structural repair, re-membrane and re-fit.

Important: In NSW, waterproofing on jobs over $5,000 must be done by a licensed builder under HBCF cover. If your original builder is still trading and the job is under 6 years old, you may have a major-defect claim. We can help you assess it.

About these numbers: Indicative price ranges based on Sydney supply & labour costs as at May 2026. Actual cost depends on access, structural condition, plumbing layout and finish selections. We provide written fixed-price quotes after an on-site assessment.
