What is leak detection in Tzummarum and why it matters
Leak Detection Tzummarum focuses on precisely locating water leaks in homes and business premises in the village center and rural areas of the municipality of Waadhoeke in Friesland, without demolition. Due to the influence of sea winds and heavy rain in the area around the Wadden Sea dike and the polder, the risk of roof leaks, water penetration through walls, and hidden water pipe leaks is real. At Ultrices Leak Detection, we combine local knowledge with building physics and mechanical engineering measurement methods to provide you with clarity quickly. We deliver an Expertise Report within three days suitable for your building or contents insurance, allowing you to immediately contact your contractor or installer. Thanks to our partnership with insurers, no cure no pay promise, and coverage guarantee, you are 100 percent risk-free.
How leak detection works in Tzummarum without demolition
We combine thermography, acoustic measurement, tracer gas, and moisture analysis to provide a conclusive diagnosis. Non-destructive testing keeps your finish intact and prevents unnecessary costs. On bitumen, EPDM, or PVC roofs, we test using controlled water loading and thermal imaging. On brick facades with cavity walls, we assess mortar joints, lead flashing, window frame joints, and waterproofing. In bathrooms, we trace the water flow of the shower, drain, and sealing tape using dye or smoke. If you want to see exactly how this is done, read on at This is how we find leaks without hacking..
Our leak detection process step by step
- Intake and analysisYou describe complaints such as damp patches, loss of pressure, or a high water bill; we examine the year of construction, pipe routes, and recent weather data from the KNMI and formulate the correct hypothesis.
- Safe and smart measurement planIn accordance with VCA VOL and NEN 3140, we work safely, select the best sequence of measurements for each situation, and coordinate with you and, if applicable, Wetterskip Fryslân or the municipality when an outdoor investigation is required.
- Non-destructive testingWe measure with an infrared camera, electro-acoustic microphone, correlator, cavity endoscopy, and moisture meters, and where necessary, we use tracer gas containing hydrogen and nitrogen for micro-leaks.
- Validation and proofWe verify the cause with a targeted spray test on the roof or facade and pinpoint the leak area with markings and photos so that the repairer knows exactly where to open.
- Report and adviceYou will receive a complete Expertise report within three days with measurements, images, and repair advice, ready for the insurer and contractor, with a 99 percent success rate and our no cure no pay guarantee.

Causes and signs of leakage around Tzummarum
- Water pipe pressure lossSudden low water pressure or a ticking boiler often indicates a leak in the supply or underfloor heating, made visible using acoustics and tracer gas, even in concrete floors.
- Stains and mold on the ceilingRings or mold formation above the bathroom or under a dormer indicate roof or drainage problems that we pinpoint using thermography.
- Damp cavity or cold inner wall: Damp patches, musty odor, and peeling plaster can be the result of rain penetration or damp penetrating through aging pointing and a missing damp-proof course.
- Gutter and valley gutter problemsLeakage along zinc gutters or at connections with lead flashing causes discoloration and wood rot at the eaves, demonstrable with endoscopy and a targeted water test.
- High water billUnexplained excessive consumption is often caused by a hidden pipe leak, which we pinpoint exactly down to the meter line or branch.

Techniques and tools that we use in Friesland
- Infrared thermographyThermal images show temperature jumps caused by moisture transport and leakage paths, ideal for flat roofs and underfloor heating.
- Electroacoustic correlationUsing microphones and a correlator, we determine the exact break point on water pipes under the floor or in the wall, even at low flow velocities.
- Tracer gas with forming gas: a mixture of hydrogen and nitrogen escapes through the smallest opening and is detected above the surface without risk to humans or material.
- Endoscopy and fluid measurements: through small inspection holes, we examine the cavity, roof details, and crawl space, while capacitive and resistance measurements objectively assess the moisture load.
- Spray and water test: Controlled spraying of the facade or detailing shows whether rain penetration during a westerly wind triggers the problem, crucial for facade penetration in Waadhoeke.

How do you locate a hidden leak in Tzummarum without hacking and breaking?
We combine multiple techniques to work in a targeted and damage-free manner. Examples include thermography to visualize heat flows and moisture patterns, acoustic correlation to locate flow noise in pipes, tracer gas with hydrogen and nitrogen for micro-leaks, a smoke test for flat roofs and rainwater drainage, endoscopy in crawl spaces or cavities, and pressure and dye tests for central heating and underfloor heating.
On-site in Tzummarum, we start with an intake, moisture measurement, and a plan of action. Next, we systematically measure each circuit—water pipes, central heating drains, roof, and facade sections. Using professional measuring equipment, we isolate the leak point with millimeter accuracy. You will receive an immediate verbal explanation and shortly thereafter a report with repair recommendations to minimize demolition work.
What signs indicate a leak in your home in Tzummarum and what can you do yourself immediately?
Watch out for brown circles on ceilings, peeling plaster or sealant, a musty smell, warm streaks in the floor near underfloor heating, ticking pipe noise, sudden pressure loss in your central heating boiler, or an inexplicably higher water meter reading. On the roof, blisters in bitumen or wet insulation often indicate a roof leak, while wet grout and limescale deposits say something about the bathroom.
In the event of active water damage, turn off the main valve, switch off the power in wet areas where it is safe to do so, lay down towels, and ventilate. Take photos and save the wet areas for your insurer. Call our emergency service; we are available day and night and will be on-site within an hour in Tzummarum and the surrounding Waadhoeke and Friesland.
