Detecting a water pipe leak on a riser is smart and fast. If you see wet spots near the ceiling or shaft, you want to know where the water is coming from.
We locate the leak using leak detection without demolition. We perform pressure tests, measure pressure loss, follow the pipe route along the riser, water meter, main valve, and couplings, and use thermography, acoustic detection, tracer gas, and moisture measurement.
At Ultrices Leak Detection, you receive clear advice and minimal water damage. Read our Google reviews (5 out of 5) for riser leak detection experiences and choose us to detect water pipe leaks on risers.
Detecting a water pipe leak on a riser explained
A water pipe leak on a riser is an invisible disruption in the vertical supply pipe of your drinking water installation that can cause pressure loss, damp spots, and a high water bill. The riser often runs from the meter cupboard to the top floor and supplies taps in apartment complexes, offices, and healthcare facilities. At Ultrices Leak Detection, we pinpoint water pipe leaks on risers with precision, without any demolition work, using thermography, acoustic correlation, tracer gas, and endoscopy. We adhere to NEN 1006 for drinking water installations, work according to VCA VOL and NEN 3140 standards, and provide an expert report that insurers recognize. Our team operates nationwide and is available 24/7 with an emergency service and on-site within 1 hour where possible.
How does leak detection on a riser work?
We combine scientific methods with professional detection equipment from brands such as FLIR, Trotec, Ridgid, and Testo. Think of infrared cameras for thermal pattern analysis, leak sound correlators for source localization in vertical shafts, hydrogen-nitrogen tracer gas for leakage progression, and digital moisture measurements in floors, ceilings, and shafts. Thanks to this combination, we locate a water pipe leak on a riser with a 99 percent success rate and without unnecessary demolition.

- AssessmentWe examine construction drawings, material types such as copper, PEX, or multilayer pipe, and note complaints such as pressure loss or damp spots.
- Pre-selection: we close off zones and perform a pressure test and flow measurement to determine the cross-section of the riser.
- ThermographyUsing a FLIR infrared camera, we scan shaft walls, ceiling zones, and pipe ducts for anomalous thermal images.
- Acoustic correlation: we measure leakage noise between two listening points and calculate the exact leak position in the riser.
- Trace gasWe inject forming gas and follow the gas path with a detector where moisture and air leaks converge.
- Verification and report: we confirm the location with endoscopy and provide a substantiated report with recovery advice and thermal imaging.

Signs and causes of a water pipe leak in the riser
- Signals: loss of pressure at tapping points, air in the pipes, unexplained damp patches on ceilings or walls, and squeaking noises in the shaft.
- Causes: corrosion in galvanized steel, stress cracks in PEX couplings, solder defects in copper pipes and mechanical damage during renovation.
- Risk: secondary damage to finishes, mold formation, short circuits in shaft installations, and a structurally high water bill.
- Recognition: a rapidly rising meter reading, local heat patterns in cold zones, and local moisture values above normal reference levels.
If you primarily notice pressure loss or a sudden drop in yield, read how we find the cause of pressure loss and prevent it from escalating into greater damage.
Methods and technology for detecting a water pipe leak on a riser
- Thermography: infrared detection of temperature differences caused by flowing water around the leak, ideal for hot and cold pipes in shafts.
- AcousticsUltrasonic listening equipment and leak sound correlators locate the break point of the riser to within decimeters.
- Trace gas: The hydrogen-nitrogen mixture seeks the path of least resistance, with very high sensitivity at minimal leakage.
- Endoscopy: via inspection hatches or small access points, we look live into the pipe duct and validate the findings.
These methods align perfectly with Dutch practical guidelines, such as ISSO publications and findings from research by KWR and TNO on leakage patterns in building installations. For a complete overview of our services, you can also review our explanation regarding leak detection on water pipes.

Practical examples and locations
In a residential complex managed by Waternet in Amsterdam, we located a micro-leak in a copper riser behind the stairwell. Using acoustic correlation and tracer gas, our team found the exact position without removing any finishing. In an office building in Rotterdam in the Evides area, thermal anomalies and pressure drop measurements indicated a defective compression fitting in a vertical PEX section. In Utrecht within the Vitens area and in The Hague at Dunea, we see similar patterns where aging valves and corrosion are the main causes. Our nationwide team also serves regions with PWN and WML and works closely with HOA managers for planning and safe access.
- Apartments: shared risers with branches to kitchens and bathrooms, often in shafts next to the stairwell.
- Utility: office shafts with combined piping for drinking water, sprinklers, and sprinkler supply where accurate localization is crucial.
- Healthcare and education: extra focus on continuity and hygiene with NEN and ISSO best practices for drinking water safety.
- Renovation projects: preventive scans to prevent new leaks after renovation and to validate connections.

Frequently asked questions
How to locate a water pipe leak in a riser without demolition work
We combine pressure measurement according to NEN 1006 with acoustic correlation and a geophon to pinpoint noise and vibrations in the riser. For hot water lines, we deploy a FLIR thermal imaging camera, and where necessary, we use forming gas with hydrogen and nitrogen to detect minuscule leaks. With endoscopy, we safely inspect shafts and soffit spaces so that your finish remains intact. This allows us to locate the exact spot with accuracy down to the coupling or segment, without any demolition or breaking work.
As Ultrices Leak Detection, we bring fifteen years of practical experience, certified with VCA VOL and NEN 3140. Available nationwide, emergency service possible, and often on-site within an hour. We deliver an expert report within three days and work with insurers. If you want to see how thermal imaging makes leaks visible, take a look at our thermographic approach.
What are clear signs of a leaking riser in a house or apartment?
Watch out for damp spots along shafts, the meter cupboard, or ceilings below upper floors. If you hear a soft hiss or ticking while all taps are closed, feel inexplicably warm zones in the wall, or if the pressure drops at higher taps, there is a high chance of a leak in the riser. A water meter that continues to run while everything is turned off is an additional red flag.
You can perform a quick test yourself by closing all appliances and monitoring the meter reading. If it continues to fluctuate, immediately turn off the main valve to limit damage. We will then quickly and specifically pinpoint the cause and provide repair advice that a plumber can carry out immediately. If you would like step-by-step help with determining the cause, read our clear diagnostic guide for bathroom leaks.
How much does leak detection on a riser cost and how does reimbursement via insurance work?
The investment depends on the accessibility of the shaft, the number of apartments or tapping points, and the type of piping material, such as copper, PEX, or galvanized steel. We offer a free quote within twenty-four hours, and for urgent cases, we provide a clear price indication in advance. You will receive a complete expert report with a photo report, measurement data, and clear repair advice within three days.
Damage caused by a pipe burst is often covered under buildings or contents, depending on the policy and the owner-occupier situation. We help substantiate your claim watertight and coordinate with your insurer where possible. Start immediately with a solid case file and view our insurance-proof leak detection report.
How quickly do you arrive on site and what is the on-site procedure for a riser leak?
In emergencies, we are on standby day and night, and in most regions, we are on-site within an hour. Upon arrival, we first perform a safety check and a quick baseline measurement, followed by targeted measurements using a correlator, geophon, thermography, and potentially forming gas.
