Hidden water leaks can cause serious damage to homes, commercial buildings, strata properties, and industrial facilities. Left undetected, even a small leak can lead to structural deterioration, mould growth, rising water bills, and costly repairs. At Remseal, we provide professional Water Leak Detection Services throughout Sydney using advanced non-invasive technology to accurately locate leaks without unnecessary demolition.
Our experienced technicians specialise in identifying the source of water ingress, moisture intrusion, and concealed plumbing leaks using thermal imaging, moisture mapping, micro-camera inspections, pressure testing, and flood testing techniques.
Whether you're experiencing a leaking balcony, roof leak, bathroom leak, rising damp, or unexplained moisture damage, our leak detection specialists can accurately diagnose the problem and provide a detailed investigation report.

Finding the source of a water leak is often far more complex than simply identifying where water appears. Water can travel significant distances through walls, ceilings, concrete slabs, masonry, and waterproofing systems before becoming visible.
Our Water Leak Detection Services focus on locating the true source of the leak, allowing property owners, builders, insurers, and strata managers to implement the correct remediation strategy.
Our Leak Detection Methods Include:
By combining multiple testing methods, we can accurately diagnose even the most challenging water ingress issues.
Balcony Water Leaks
Leaking balconies are one of the most common building defects in Sydney. Failed waterproof membranes, inadequate drainage, cracked grout, and deteriorated sealants can allow water to penetrate beneath tiled surfaces and enter internal walls and ceilings.
Our team conducts comprehensive balcony leak investigations to determine the exact point of water entry and assess the condition of the waterproofing system.
Roof Leak Detection
Roof leaks can be caused by damaged flashings, cracked roof tiles, deteriorated membranes, blocked gutters, or construction defects. Water often travels through roof cavities before appearing internally, making the source difficult to identify.
Using thermal imaging and moisture mapping, we trace the leak path and identify the source with precision.
Shower Leak Detection
A leaking shower can cause extensive damage to surrounding walls, flooring, and adjacent rooms. Our non-invasive shower leak detection services can determine whether the leak is caused by waterproofing failure, plumbing issues, movement cracks, or failed sealants.
Basement and Retaining Wall Leaks
Basements and below-ground structures are particularly vulnerable to hydrostatic pressure and waterproofing failures. We investigate basement leaks, retaining wall seepage, and underground water ingress issues affecting residential and commercial properties.
Plumbing Leak Detection
Concealed plumbing leaks behind walls, under floors, and within concrete slabs can remain hidden for months. Our specialised leak detection equipment allows us to locate plumbing leaks quickly while minimising disruption.
Thermal Imaging
Thermal cameras allow us to identify temperature variations caused by moisture hidden behind walls, ceilings, and floors. This technology helps locate leaks that may not yet be visible to the naked eye.
Moisture Mapping
Using calibrated moisture meters, we measure moisture levels within building materials to determine the extent of water penetration and identify affected areas.
Micro-Camera Inspections
Where access permits, miniature inspection cameras can be inserted into cavities and concealed spaces to visually inspect leak pathways and building defects.
Flood Testing
Flood testing is commonly used for balconies, rooftops, planter boxes, podium decks, and wet areas. Controlled water testing allows us to confirm waterproofing failures and identify leak locations.
Dye Testing
Specialised tracing dyes are used to track water movement through building systems, helping isolate the precise source of water ingress.
