Pricing guide
Costs are driven by the initial callout plus hourly labour and any materials used during diagnosis and repair. Intrusive investigations that require cutting access or protecting finishes typically add labour time, while full-area membrane replacement generally involves larger material quantities, longer cure/dry windows and possible coordination with other trades. Work outside standard hours is usually charged at a higher rate (often 1.5–2x).
Callout fee and labour time
An initial callout plus hourly labour forms the base of most diagnostic visits, and longer investigations increase total labour time.
Intrusive access and finish removal
Cutting access panels or removing finishes to locate a leak requires careful labour and temporary protection, increasing the scope of the diagnostic visit.
Extent of waterproofing damage
A small, localised leak usually needs less work than a failed membrane that requires full-area replacement and more materials.
Coordination with other trades
Extensive remediation often needs a tiler, plumber or carpenter, which can add coordination time and may be quoted separately.
After-hours attendance and timing
Visits outside normal hours are typically charged at a higher rate (often 1.5–2x) and can increase overall cost.
