Detect a leak in a wall without chiseling
Detecting a leak in a wall requires precision, speed, and minimal disruption. At Ultrices Leak Detection, we locate a leak in your wall using thermography, acoustics, and tracer gas while your home or business premises remain intact. Damp spots, mold, peeling paint, loose plaster, or a musty odor tell us a lot about the source of the moisture. With professional measuring equipment such as a FLIR infrared camera, Trotec and Tramex moisture meters, a Ridgid endoscope camera, and Testo data loggers, we pinpoint the leak to the centimeter. Our specialists are VCA VOL and NEN 3140 certified and work in accordance with NEN 1006 for drinking water installations. If you want to know exactly how we find leaks without breaking anything, read on about Leak detection without demolition or breaking at your home or business premises.
Causes and types of wall leakage in homes and businesses
- Water pipe leak: small perforation or corrosion in a copper or plastic pipe in the wall, often signaled by pressure loss and a rising water bill
- Drain or central heating pipe: leakage due to subsidence, cracking, or aging connections causing moisture in the wall and cavity
- Rain penetration and facade penetration: penetration of rainwater through porous mortar, cracks around window frames, or broken facade joints that wet walls from the outside in
- Rising damp and capillary action: rising groundwater due to missing base sealing, salt crystals, and peeling plaster as characteristics
- Condensation and thermal bridge: moisture due to vapor diffusion and temperature difference at cold spots in the wall, such as concrete columns and lintels
Our leak detection method and scientific basis
We detect leaks in walls using a protocol that rules out causes and objectively establishes the true source. Thermography shows heat patterns and temperature gradients indicating flowing water. Electroacoustic detection with a geophon makes the leak sound audible when pressure is applied to the pipe. Tracer gas based on hydrogen and nitrogen finds micro-leaks that are invisible and inaudible. A fluorescein dye test makes infiltration trails visible in drains and shower walls. Endoscopy inspects the cavity wall or pipe ducts through a drill hole the size of a pencil. We record relative humidity and dew point with data loggers and link this to capillary action, hydrostatic pressure, and vapor diffusion—concepts found in building physics and materials science. Our report follows a reproducible format with measured values, photos, and conclusions, suitable for insurers and damage repair.
- Thermographic cameraFLIR or Fluke infrared images capture temperature differences that indicate moisture and flow in the wall.
- Moisture meters and hygrometersTrotec, Tramex, and Gann instruments measure moisture percentages in building materials and relative humidity.
- Tracer gas set: inert gas mixture under low pressure escapes through the leak, after which sensors locate it exactly
- Acoustic correlator and geophon: microphones filter out leakage noise and triangulate the source
- Endoscope camera: Ridgid inspection tool looks inside cavity, shaft, or cavity without demolition
Step-by-step plan for detecting a leak in a wall
- Intake and analysis: we discuss complaints, year of manufacture, materials, and previous repairs, and check water consumption and pressure loss
- Visual inspection: we mark damp spots, cracks, and risk details around window frames, expansion joints, and penetrations
- Measuring is knowingWe combine thermography, moisture measurement, acoustics, and tracer gas until a clear leak pattern emerges.
- Verify and record: we confirm the source with a second method and document everything with photos and a measurement report
- Recovery advice and aftercare: you receive an expert plan with priority, cost indication, and prevention tips, including insurance frameworks
Leak detection process request
Common signs and quick checks
- Slight discoloration or ring formation: initial damp patches around baseboards, electrical outlets, or window frame connections often indicate a wall leak
- Salt efflorescence and crust formation: crystals on plasterwork betray rising damp or penetration from the cavity wall
- Persistent musty smell: microbial life and moisture load in the wall cause a recognizable odor for a long time
- Clammy-feeling wall: a cold and damp-feeling zone indicates condensation or leakage near a thermal bridge
- Unexplained water bill: a rise may indicate a leaking water pipe in the wall, for which a pressure test will provide a definitive answer.

Frequently asked questions
How do you recognize a leak in the wall and not just condensation?
Pay attention to signs that keep recurring or worsen. Think of round damp circles, mold, salt efflorescence such as white crystals on the plasterwork, peeling paint, or a musty smell. If the water meter continues to run while all taps are closed, or if you hear a soft humming sound in the wall, there is often a pipe leak. Moisture that occurs primarily during rain indicates penetrating damp or rainwater entering through the facade more often than condensation.
We verify the difference using moisture measurements, thermography, dye tests on drains, and, if necessary, a pressure test on supply or central heating pipes. Without any demolition work, we map the pattern and link it to the source. If you are thinking of the facade or cavity, read on about detect rain penetration at the facade.
Which professional method works best to detect a hidden pipe leak in a wall without breaking anything?
The best approach depends on the source. For supply or central heating, we use thermographic scans with an infrared camera to visualize heat trails and thermal bridges, plus acoustic and ultrasonic microphones to pinpoint the leak sound. In case of doubt, we use tracer gas with a safe hydrogen-nitrogen mixture to find micro-leaks. For drainage and shower zones, we use dye tests and endoscopy to look behind the wall or into the cavity. Everything is done non-destructively.
We combine measurements to reach a conclusive conclusion and record it in a measurement protocol. If a building physics cause plays a role, such as capillary action or penetrating damp, we perform a spray test or smoke test in the cavity. We work VCA VOL and NEN 3140 certified, with a 99 percent success rate and no solution, no payment. Interested in cavity wall inspection without demolition work?

How much does it cost to detect a leak in a wall and is it covered by insurance?
The costs depend on accessibility, the type of construction, and the number of measurements required. We work with a clear rate per survey, including professional equipment and a comprehensive report. You will receive a free, customized quote within 24 hours. Generally, building or contents insurance covers the cost of tracing and consequential damage if a covered event occurs. Check your policy conditions for exact coverage.
We deliver an Expertise Report within three days, including photos, measurements, cause, source location, and repair recommendations, prepared for quick acceptance by insurers. Thanks to our experience and five-star rating, you help your claim move smoothly through the process. If you want to know immediately how the report strengthens your case, view Example and explanation of an insurance report.
