Leak Detection
What is included
Around 95% of wet-area leaks in Sydney come from failed grout and sealant at the wall-to-floor junction, not from the pipework. We prove exactly where the water is going using a combination of pressure testing, moisture meter mapping, thermal imaging and a controlled flood test — then we show you the photographs and the evidence.
If the failure is seal-only we reseal on the spot. If the membrane has failed, we quote a complete strip and re-seal, with a fixed price agreed before any work starts.
Our scope of work
- Pressure test to isolate supply and waste lines
- Controlled flood test with infrared camera
- Moisture mapping of adjacent rooms and subfloor
- Live photo report of the failure point
- Fixed-price repair proposal with options
- Optional termite and rot assessment of framing
When you need it
- Water appearing downstairs or in adjoining rooms
- Staining or bubbling paint near wet areas
- Persistent musty odours under floors

Frequently asked questions
Straight answers to the questions we are asked most often across Sydney.
How much does leak detection cost?
from $395 is our starting price for a standard leak detection job in metropolitan Sydney. Final pricing depends on the size of the area, the condition of the substrate, access and whether any tile or substrate repair is required. We confirm a fixed, itemised price before work begins — never an hourly estimate that grows.
How long does leak detection take?
Expect Same-day diagnosis. Most jobs of this type are completed in a single visit by a licensed tradesman, with the area protected, cleaned and left ready for use. Larger works such as balcony rectification may take several days depending on access and the extent of tile removal.
Is leak detection covered by a warranty?
Yes. This service carries a written 10 years warranty, issued with a photographic record of the installation. The certificate covers both labour and materials for the waterproofing work we performed. If anything we installed fails inside the warranty period we return and rectify it at no charge.
Do you need access to the property first?
Not to give you a price. Send photos of the affected area through our quote form and we will come back with a fixed price, usually within the hour. We only attend the property for a formal inspection when the photographs are inconclusive or when a certificate is required by your body corp, insurer or tiler.
