We detect ceiling leaks quickly and without any demolition work. If you see brown circles or drips near a light fixture, we minimize damage.
We use thermography, an infrared camera, acoustics, tracer gas, dye, pressure testing, endoscopy, and a moisture meter. This allows us to accurately locate every water leak.
Whether the source is water pipes, drains, central heating pipes, roofing, bathroom, kitchen, rainwater, or sewer, you will receive a leak detection report for the insurer and a repair plan. We are Ultrices Leak Detection with 5 out of 5 Google reviews. read our reviews on detecting ceiling leaks.

Detecting ceiling leaks explained
Ceiling leak detection involves the targeted and non-destructive identification of the source of water infiltration located in or above a ceiling. At Ultrices Leak Detection, we combine building physics with advanced measurement techniques to quickly locate minor pipe leaks, seeping rainwater, condensation, and hidden moisture bridges. We work nationwide for private individuals and businesses, are VCA VOL and NEN 3140 certified, and deliver an expert report accepted by insurers within three days. Our success rate is 99 percent, we work without demolition or breaking, and with a "no solution, no payment" policy, you are completely risk-free.
Signs and causes of a leaking ceiling
A wet or discolored ceiling is caused by various sources. By examining the context, such as bathroom use, recent rainfall, or loss of water pressure, we link symptoms to the most likely cause and confirm this with measurements.
- Typical symptoms: brown circles, mold growth in corners, peeling paint, loose plaster, sagging plasterboard, musty odor
- Sources in installations: leaking copper or PEX water pipe, failing compression fitting, defective central heating pipe or underfloor heating, leaking drain or riser pipe
- External sources: roof leakage in bitumen, EPDM, or PVC roofs, broken roof penetration, clogged rainwater drain, crack in lead flashing or roof edge
- Building physics causes: condensation due to thermal bridge, high relative humidity, capillary action in building materials, leaky vapor barrier
If you are unsure whether rainwater is entering through the roof or coming from the system, read how we first rule out the building envelope in the case of a wet ceiling using a water test and thermography. If you want immediate in-depth information on roof sources, view our approach for targeted roof leak detection.
Our method without hacking or breaking
We detect ceiling leaks using measurement protocols that align with NEN 1006 for drinking water installations, NEN 3215 for internal sewage systems, and the forensic principles of ASTM E2128 for water intrusion. We use calibrations and reference measurements to ensure that conclusions are reproducible and the report is legally sound. Everything is done non-invasively so that your ceiling and finish remain intact.
- Thermography: FLIR infrared camera visualizes cold spots caused by evaporation and leaking pipework in floors above your ceiling
- Acoustic correlation: ultra-sensitive microphone listens for leakage sounds in pressurized pipes, even at minimal volume flow
- Trace gas: forming gas with hydrogen finds microcracks, the sniffing probe detects gas migrating to the ceiling via the leak path
- Endoscopy and dye: we look into the structure through a small inspection opening or rosette; fluorescein follows waterways without contamination
If minimal damage is crucial, choose our proven leak detection without demolition where we capture the exact source using combined sensors.
Step-by-step ceiling leak detection
We work according to a clear step-by-step plan so that you know exactly what we are doing and why. With this process, we ensure speed, safety, and verifiable results.
- Intake and hypothesis: we analyze complaints, time of onset, floor plan, installations, and roof details, and form a working hypothesis
- Orientation and baseline measurement: visual inspection, moisture measurement with capacitive and dielectric meters, and documenting the initial situation with photos and thermography
- Targeted tests: pressure test of water pipe or central heating, smoke or water test on facade or roof, tracer gas or dye to confirm the leak path
- Corroboration: second confirmation technique so that cause and location are unambiguous, including exclusion of alternative scenarios
- Cancellation and advice: immediate verbal result, emergency measure where possible and recovery advice including prevention tips against recurrence

Types of ceiling leaks and practical examples
Every situation requires specific measurements. By recognizing types and context, we save time and limit consequential damage.
- Bathroom above the ceiling: Leaking shower corner due to open sealant joint or porous grout, often visible as a ring around a light fixture or along walls
- Kitchen or laundry room: dripping due to defective dishwasher or washing machine connection, combination of acoustics and dye provides evidence
- Rain-related leak: wet ceiling especially after wind from a specific direction, we specifically test facade openings and roof details with a controlled water test
- Seasonal condensation: thermal bridge in concrete beam or steel profile, thermography shows pattern and data logger records dew point exceedance
If water is coming from a ceiling after a rain shower or you notice a loss of pressure on the water meter, let us isolate the root cause and rule out the rest. If you would like to delve deeper into installation lines and leakage behavior, please view our page about precisely detect water leakage.

Frequently asked questions
Damp spot in ceiling: what now and how to have a ceiling leak professionally detected.
Immediately close the main valve if you see active water flow and switch off the power to fixtures near the leak. Take photos and note when the spot appears or worsens, for example after showering or rain. Then contact us so that we can be on site within 1 hour. We are available 24 hours a day, 7 days a week for business and private clients.
During the visit, we pinpoint the source without any demolition or breaking. You will receive a clear plan of action and an expert report within 3 days. If your bathroom is located above the damp patch, read how we resolve ceiling damage under bathrooms via Ceiling under bathroom renovation.
Which method do you use to detect ceiling leaks without demolition?
We combine thermal imaging inspections with acoustic measurements, moisture measurements, and tracing techniques. Examples include thermography with a FLIR thermal imaging camera to identify hot water pipes, an acoustic microphone for dripping sounds in drains or piping, and fluorescein dye tests to confirm leaking wet areas. Where necessary, we perform pressure tests and a smoke test on roof penetrations or flat roofs affected by rain.
This non-destructive approach identifies the exact cause in 99 percent of cases, from a crack in the drain to a leaking central heating pipe or condensate bridge. We work with professional detection equipment, are VCA VOL and NEN 3140 certified, and adhere to our no-cure, no-pay policy. This allows you to avoid unnecessary demolition and carry out targeted repairs.
How much does it cost to detect a ceiling leak and do you get reimbursed by the insurance?
You will receive a free quote within 24 hours with a fixed price for the inspection, including a measurement report and photo report. After our visit, you will receive a comprehensive expert report within 3 days that insurers accept, including the cause, consequential damage, and repair advice. We operate nationwide and, where desired, coordinate directly with your insurer.
Damage caused by pipe leaks or water penetration through the roof and facade is often covered under buildings insurance, while consequential damage to contents is sometimes covered under contents insurance. Always check your policy or ask us to review it. If you want to know exactly what documentation insurers require, please view Sample reports for insurance.
How quickly do you come by in case of an emergency, and what is the process from the initial report to recovery?
In urgent cases, we are usually on site within 1 hour. The examination itself typically takes 60 to 120 minutes. You will receive an immediate preliminary diagnosis and advice to limit further damage. We then provide the full measurement report and expert report with photos and clear repair steps.
With our network of contractors and installers or your preferred company, we plan targeted repairs, such as fixing a leaking drain or sealing a roof penetration. No solution, no payment thanks to no-cure-no-pay and coverage guarantee.
