Bathroom Leak Detection Services
Fast, non-invasive leak detection for hidden bathroom issues
A small leak in your bathroom could cost you thousands, and in most cases, you won’t see it coming. Water from toilets, showers, sinks, or baths can seep silently into your walls, floors, and ceilings. By the time stains or damp patches appear, the damage is already done.
Our bathroom leak detection service helps you stop the problem early, before it spreads and becomes costly. If you suspect something’s wrong, the best time to act is now.
What Causes Leaks in Bathrooms?
Bathrooms get used multiple times a day, every day. Over time, even the strongest fittings wear down. Seals degrade. Joints loosen. Pipes shift. And the result is often a slow, silent leak that goes unnoticed until the smell of mould or a spike in your water bill gives it away.
Toilet Leaks
Toilets are a frequent culprit. The wax or rubber seal under the toilet base can wear out over time, letting water leak into the subfloor. Internal parts such as flappers and fill valves can also fail, leading to a constantly running toilet or small drips that go unnoticed. Even the water supply hose behind the toilet can develop tiny leaks at the joints.
Shower and Bathtub Leaks
Showers and bathtubs are especially vulnerable to hidden leaks. Constant water exposure can break down grout and sealant between tiles. Water may then seep behind the tiles or under the shower tray. The seal around a bath can also degrade, especially if it’s not been properly maintained or was installed with movement in the frame. Waste pipes underneath baths are another weak spot — if they’re loose or misaligned, water can leak slowly into the floor space without being visible from above.
Sink and Vanity Leaks
Sinks and vanity units often hide leaks inside cupboards or beneath the surface. Supply pipes under sinks can corrode, especially in older properties. Plastic or rubber seals in the waste trap may degrade with age and use. In many cases, damp inside a vanity unit goes unnoticed until the smell of mildew gives it away.
Hidden Pipe Leaks
Pipes inside walls and under floors can crack or shift due to building movement, temperature changes, or old age. Because these leaks are entirely out of sight, they tend to do the most damage before they’re found. A small split in a pipe behind plasterboard might release water 24/7, soaking timbers and insulation without any outward sign until serious damage appears.
What Our Bathroom Leak Detection Service Includes
We offer a thorough, non-invasive investigation using professional-grade equipment. Our service includes:
- A full inspection using moisture meters, thermal imaging, acoustic sensors, and tracing dyes, where needed
- Pinpoint the location of leaks so you’re not wasting money on unnecessary or inaccurate repairs
- A clear written report with photographs, measurements, and technician notes
- The sound of water running when no taps are on
- Advice on repair options and recommendations for trusted tradespeople if required
- Support for insurance claims, including Trace and Access documentation
We typically allow a full working day per leak detection visit, although the inspection itself usually takes 1 to 2 hours. This gives us enough time to investigate properly and compile a detailed, high-quality report.
Signs You Might Need Leak Detection
If you’ve noticed any of the following signs, it’s worth arranging a leak detection survey before things get worse:
- A musty smell or mould in the bathroom
- Soft or spongy flooring underfoot
- Peeling paint or warped skirting boards
- Water stains on the ceiling below the bathroom
- The sound of running water when the taps are off
- Unexpected increases in your water bill
Even if you’re not entirely sure, it’s better to have the area checked than risk letting the problem develop. A minor leak can turn into a major issue if ignored, especially in timber-framed or older properties where water damage can affect the structure.
What Happens If You Wait Too Long?
Postponing leak detection may save a bit of money in the short term, but the long-term cost can be far greater. Continuous exposure to moisture can weaken joists, damage plasterboard, rot subflooring, and ruin bathroom fixtures. It can also lead to persistent mould growth, which not only causes health issues but is expensive to remove professionally.
We’ve seen cases where a simple leak under a toilet ended up causing thousands of pounds in repairs to the floor, ceiling below, and even electrical fittings. Early intervention always works out cheaper, and it keeps your home safe.
Insurance Claims and Trace & Access
Most UK home insurance policies include Trace and Access cover as part of buildings insurance. This covers the cost of locating and accessing a hidden leak, but not the cost of the actual repair. In other words, if you need to cut into a wall or floor to get to the source of the leak, your Trace and Access cover should pay for that part of the job.
Our reports are formatted to meet the requirements of UK insurers and include all the evidence they need to validate your claim. We aim to submit all reports within 48 hours of our visit.
It’s worth checking your policy to see what your insurer will cover. In many cases, you’ll be able to claim back the full cost of our leak detection service if you’re covered for Trace and Access.

What Happens During Your Survey
Every leak detection visit follows the same structured process, so you know exactly what to expect and what you’ll walk away with.
1. Arrival and walkthrough.
Your named technician arrives in a branded vehicle at the agreed time. We walk through the property with you, noting every area of concern such as damp patches, pressure drops or visible damage, so nothing is missed.
2. Non-invasive testing.
We deploy the right combination of tools for your situation, including thermal imaging to map moisture behind walls, acoustic listening to trace pressurised leaks, tracer gas injection for underfloor pipework, and moisture meters to measure the extent of saturation.
3. Source identification.
We isolate the leak to its precise origin point and confirm the cause — whether it’s a failed joint, a corroded section, a cracked fitting, or external water ingress. We photograph the evidence and explain our findings on-site so you’re never left guessing.
4. On-site debrief.
Pipes inside walls and under floors can crack or shift due to building movement, temperature changes, or old age. Because these leaks are entirely out of sight, they tend to do the most damage before they’re found. A small split in a pipe behind plasterboard might release water 24/7, soaking timbers and insulation without any outward sign until serious damage appears.
5. Written report delivered
Within 48 hours you receive a detailed PDF report by email. This is the document you forward to your insurer, your plumber, or your landlord. It contains everything listed below.
Your report includes
- Confirmed leak location with annotated photographs
- Identified cause (e.g. failed solder joint, cracked compression fitting, degraded pipe section)
- Thermal images and moisture readings showing the affected area
- A clear written summary of findings
- Recommended next steps for repair
- Technician name, qualifications, and date of inspection
- Insurer-ready format accepted by all major UK home insurance providers
