Signs You May Have a Balcony Leak
Have you noticed:
- Unexplained water stains on ceilings below your balcony
- Damp or wet patches around balcony edges or adjoining walls
- Cracked tiles or deteriorating grout on your balcony surface
- Peeling paint or bubbling plaster near balcony areas
- Musty smells coming from rooms below or adjacent to the balcony
- Water pooling or poor drainage after rain
- Rusting balustrades or structural components
- A constantly running water meter
If you said yes to any of the above, you may need professional balcony leak detection services. At G.X.R Plumbing & Gas, we specialise in locating hidden balcony leaks quickly across the entire Perth metro area.
Using advanced acoustic leak detection technology and non-invasive testing methods, our licensed plumbers can pinpoint the source of your balcony leak without unnecessary damage to tiles, membranes, or structural elements.
While some leaks are obvious such as visible cracks or surface pooling, many balcony leaks are silent and develop beneath tiles or waterproofing layers. Over time, these leaks can cause serious structural damage, including concrete deterioration, timber rot, mould growth, and internal ceiling damage.
Early balcony leak detection can save you thousands in long-term repair costs.
Our Perth balcony leak detection specialists can identify and repair:
- Leaking balcony surfaces and substrates
- Failed waterproofing membranes
- Cracked grout and tile leaks
- Drainage and overflow issues
- Pipe leaks beneath balcony structures
- Ceiling damage caused by balcony leaks
- Balcony re-sealing and waterproofing repairs
Our fully licensed Waterwise plumbers provide honest, fast, reliable, and affordable balcony leak detection services throughout Perth.

We Use Advanced Ultrasonic Technology for Accurate Balcony Leak Detection
We’ve been servicing Perth for over 20 years, specialising in professional balcony leak detection. While some balcony leaks are easy to spot, many are hidden beneath tiles, within waterproofing membranes, or inside structural elements and require specialised equipment to locate.
Our licensed plumbers use advanced ultrasonic leak detection technology to pinpoint even the smallest hidden leaks, including failed waterproofing membranes, cracked grout, drainage issues, and pipe leaks beneath balcony surfaces. Using 40 kHz acoustic sound waves, we can detect water movement beyond normal hearing range.
With fast, non-invasive balcony leak detection across Perth, we help prevent structural damage, mould growth, and costly repairs. Contact us today.
