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.

Frequently asked questions

How are investigation costs usually structured?
Typically there's an initial callout plus hourly labour and any materials used during the visit. If the investigation requires intrusive access or leads to full-area waterproofing, material quantities and labour time usually increase accordingly.
Will the investigation include fixing tiles or finishes?
A standard diagnostic visit often covers locating the leak and small localised repairs, but intrusive investigations usually include only temporary protection and not full repair of finishes. Subsequent replacement or restoration of tiles and finishes is commonly quoted separately.
How long does a leak investigation usually take?
Simple diagnostic visits are typically completed in a single attendance, but intrusive testing or complex leaks can take longer due to access work. Full-area membrane replacement usually requires longer cure and dry windows, which extend the overall timeframe.
Do waterproofers need to be licensed?
Yes — licensing is mandatory for waterproofing work in this listing. You should check that any provider holds the required licence for waterproofing before engaging them.
