Water pipe leak detection helps you quickly resolve damp spots and high water bills. Our specialists find the leak without any demolition using thermography, acoustic measurement, tracer gas, and pressure testing.
We work in kitchens and bathrooms, crawl spaces, walls, floors, ceilings, and gardens, on copper, PVC, PEX, and steel, from water meters to couplings and branches, so that water damage and mold are stopped.
After water pipe leak detection, we provide a clear insurance report and repair advice. Read our Google reviews 5/5 via experiences with water pipe leak detection and call Ultrices leak detection.

What is water pipe leak detection and why it matters
Water pipe leak detection involves the targeted locating of a hidden leak or pipe rupture in the drinking water installation without any demolition or breaking work. At Ultrices Leak Detection, we combine acoustic correlation, thermography, tracer gas, and pressure testing to determine the exact leak position with a 99 percent success rate. We work in accordance with NEN 1006 for drinking water installations and the VEWIN Waterworksheets, holding VCA VOL and NEN 3140 certifications. Thanks to our expert report within three days and our collaboration with insurers, you can address damage repair faster and with insurance coverage. You often notice signs such as a ticking water meter, wet spots, or unexplained pressure loss. We assist you nationwide and are often on-site within an hour in urgent cases, 24/7, for both residential and commercial properties in cities such as Amsterdam, Rotterdam, Utrecht, The Hague, Eindhoven, and Groningen.
Signs of a water pipe leak that you must not ignore
- Unexplained loss of pressure: The shower becomes weaker or taps provide less water while the main valve is fully open.
- High water billA suddenly higher bill while your usage remained the same may indicate a leak behind the water meter.
- Wet or warm places: Damp skirting boards, discoloration of walls, or localized warm zones on the floor near hot water pipes.
- Noise in pipes: Whispering or hissing sounds when installations are stationary, picked up by a geophone or acoustic sensor.
- Mold and musty smellCapillary action transports moisture through building components, resulting in mold formation.
How water pipe leak detection works step by step
- Inventory and measurementsWe check the water meter for micro-consumption, perform a manometric pressure test, and establish the installation boundaries according to NEN 1006.
- Acoustic correlationUsing a correlator and contact microphones, we analyze the leakage noise and determine the crossover point where the signal peaks.
- Thermography and moisture measurement: Infrared camera and moisture meters show anomalous surface temperature and moisture gradients through emissivity patterns.
- Tracer gas methodWe inject forming gas with hydrogen and nitrogen into the circuit and detect leakage with an H2 sensor for plastics and poorly conductive surfaces.
- Endoscopy and pinpointUsing an endoscope, we inspect ducts or shafts and perform precise localization for targeted repair without demolition work.

Professional techniques and equipment for water pipe leak detection
- Acoustic geophone and correlator: For metal and plastic pipes with signal analysis and time-delay cross-correlation, based on TNO acoustics principles.
- Thermographic inspectionIR images reveal heat patterns in hot water pipes or convection currents along leakage paths.
- Tracer gas detectionForming gas 95 5 with extremely small molecules finds micro-leaks with high reliability and is safe for indoor spaces.
- Pressure and flow rate logging: Data loggers on sections provide pressure drop and intermittent flow, useful for nocturnal micro-consumption and hard-to-catch leaks.
- Endoscopy and dye test: Endoscopes in shafts and fluorescein for visual inspection of flow routes along pipes and bushings.

Causes of pressure loss and hidden pipe bursts in the house
- Corrosion and pitting loss: Aging copper pipes can develop pinholes, often with hard water quality or galvanic couplings with steel.
- Freezing and evictionWinter cold causes cracks in poorly insulated routes, especially in crawl spaces and facade penetrations.
- Mechanical loadVibrations from pumps or subsidence in the floor put couplings under stress, resulting in hairline cracks.
- Assembly errors: Insufficient deburring of plastic pipes or bends pulled too tightly cause subsequent leakage.

Practical example and result
In Utrecht, a family was struggling with a ticking water meter and damp patches near the skirting board. Our specialist placed correlator microphones at two taps and found a sharp peak under the kitchen. Thermography showed a warm streak line along a hot water tap section. Using tracer gas, we confirmed the exact position at a compression fitting. The installer was able to lift a tile in a targeted manner and replace the fitting. The damage remained minimal, the flow rate normalized, and the insurer accepted our report without any additions. This is how water pipe leak detection should work.

Frequently asked questions
How do you locate a leak in the water pipe without hacking and breaking?
We combine acoustic correlation with geophon, thermography with FLIR, nitrogen- and hydrogen-based tracer gas, cavity endoscopy, and precise pressure tests. This allows us to detect hot and cold water leaks in copper, PEX, and PVC pipes with centimeter accuracy. Our measuring equipment from Trotec and Ridgid, among others, provides hard data for a conclusive diagnosis.
You benefit from 15 years of experience, VCA VOL and NEN 3140 certification, a 99 percent success rate, and no solution means no payment. We work nationwide, without demolition or breaking, and deliver an expert report within three days. If you want to see how heat leaks become visible in wet shower walls, take a look. thermography for bathroom leaks.
How much does water pipe leak detection cost, and is it covered by insurance?
We work with a fixed price per investigation, including reporting, photographic evidence, and repair advice. After registering, you will receive a clear, free quote within 24 hours. No hidden costs and 100 percent risk-free thanks to our no cure, no pay promise if no cause is found.
Insurers often reimburse leak detection under buildings insurance for consequential damage, provided it is well-substantiated. Therefore, we deliver an expert report within three days that meets the requirements of Dutch insurers and guarantee coverage where applicable. Always check your policy conditions. Read more about reimbursement and processing via Insured leak detection for bathroom leaks.
How soon can you come and how long does it take to locate a water pipe leak?
With our 24-hour emergency service, we are often on-site within one hour. A full inspection takes an average of 60 to 120 minutes, depending on the building structure, pipe length, and accessibility. During the measurements, we keep water damage to a minimum.
Upon localization, we immediately take emergency measures, such as temporarily shutting off or clamping off a section of the pipe, and you will receive a clear repair plan. You will receive the expert report within three days. We work with insurers and score 5 out of 5 stars on Google reviews. For immediate assistance with wet areas, check out our emergency service for bathroom leak.
What works better for water pipe leak detection, acoustic testing or thermography?
That depends on the type of pipe, the water temperature, and the construction. Thermography is ideal for hot water pipes in walls and floors, because temperature differences make moisture patterns visible. Acoustic correlation and geophony are strong in copper or PEX pressure pipes, especially when the leak emits sound waves.
For silent or deep-seated leaks in sand cement or under tiled floors, we often use tracer gas to measure upwards through micro-cracks. Endoscopy helps to map hollow spaces, and a pipe locator determines the exact pipe route. We select the best combination for each situation, ensuring you quickly receive a reliable and non-destructive diagnosis from Ultrices leak detection.
